Abstract
OBJECTIVE Patients with pollybeak deformity who underwent rhinoplasty were analyzed retrospectively and across centers to identify their primary risk factors, preventative measures, and treatment modalities. PATIENTS AND METHODS The retrospective data of 100 pollybeak deformity cases (61 males and 39 females) were enrolled in our study. The causes leading to pollybeak deformity were evaluated and classified as (1) Over-resected bony dorsum, (2) Excessive supra tip scarring, and (3) Inefficient tip support causing an under-projected tip. The treatments applied to patients with pollybeak deformity were retrospectively evaluated and classified as (1) Triamcinolone acetonide injections (one or two injections), (2) Filler injection over the bony dorsum to balance, (3) Using a graft to achieve the desired nose shape, (4) Trimming down the excessive supra tip soft tissue and/or tip cartilage, and (5) Enforcing the tip support. RESULTS Our results showed that the major cause of pollybeak deformity was excessive supra-tip scarring (48%). The other reasons are inefficient tip support, causing an under-projected tip (28%), and over-resected bony dorsum (24%). The modalities for the treatment of pollybeak deformity were (1) Trimming down the excessive supra tip soft tissue and/or tip cartilage (30%), (2) Triamcinolone acetonide injections (one or two injections) (28%), or (3) Enforcing the tip support (28%), (4) Using a graft to achieve the desired nose shape (14%) and (5) Filler injection over the bony dorsum to balance (6%). In some patients, more than one treatment modality was applied. Triamcinolone acetonide or filler injections were the non-surgical therapies for pollybeak deformities. CONCLUSIONS We concluded that excessive supra-tip scarring is not directly related to a surgical error but rather depends on the patient and tissue healing. Care should be taken to avoid over-resecting the bony dorsum. Tip support should be provided to prevent inefficient tip support from causing an under-projected tip. However, efforts should be made to minimize supra-tip dead space and possibly proceeding pollybeak formation through proper bandaging.

Abstract
OBJECTIVE We investigated symptom scores and quality of life in unilateral posterior canal benign paroxysmal positional vertigo (BPPV) patients. PATIENTS AND METHODS In this retrospective and multicentric study, 78 patients with unilateral posterior canal BPPV (47 right-sided and 31 left-sided) were included. All patients have performed the Standard Epley maneuver. Features of the nystagmus [nystagmus duration (second), latent period (second)] and features of the disease [side (right or left-sided), disease duration (years), and recurrence of disease (present or absent)] were noted. Before and 1 week after the Epley maneuver, all patients were evaluated using the Vertigo Symptom Scale (VSS), Vertigo Dizziness Imbalance Symptom Scale (VDI-SS), and Vertigo Dizziness Imbalance health-related quality of life scale (VDI-HQoL). RESULTS Our results showed that VSSs of the right-sided group were significantly higher than those in the left-sided group before and 1 week after the maneuver (p<0.05). One week after the maneuver, VDI-HQoLs of the left-sided group were significantly higher than those in the right-sided group (p<0.05). In all right-sided and left-sided groups, at 1 week after the maneuver, VSSs were significantly lower, and VDI-SSs and VDI-HQoLs were significantly higher than those before the maneuver (p<0.05). As VSS values increased, VDI-SS and VDI-HQoL values decreased (p<0.05). In the left-sided group, VSS values decreased, and VDI-HQoL values increased. As disease duration increased, VSS values increased before the maneuver (p<0.05). In females, VSS values increased, and VDI-SS and VDI-HQoL values decreased before the maneuver (p<0.05). CONCLUSIONS In posterior canal BPPV, the Epley maneuver effectively decreased VSS values and increased VDI-SS and VDI-HQoL values. In the left-sided BPPV group, there were lower VSS values and higher VDI-HQoL values that showed better quality of life of the patients. Older age and female gender are other factors related to lower quality of life with higher symptom scores.

Abstract
OBJECTIVE In the present study, we evaluated patient satisfaction with cap grafts by Rhinoplasty Outcomes Evaluation (ROE) scores. Mini cap and wide cap grafts were applied. PATIENTS AND METHODS A total of 80 patients who underwent a rhinoplasty operation with cap graft application to the tip region were included in the study. According to the cap graft size, there were two groups: Group 1 consisted of 40 patients with cap graft size ≤7 cm (mini cap group). Group 2 comprised 40 patients with cap grafts ≥8 cm (wide cap group). Patients in groups 1 and 2 underwent evaluations based on the following criteria at preoperative, postoperative-1st month, and postoperative-1st year intervals: (1) Rhinoplasty Outcomes Evaluation Questionnaire (ROE), (2) tip projection (cm), (3) nasal dorsum length (cm), (4) tip projection ratio (Goode), (5) nasofrontal angle, and (6) nasolabial angle. RESULTS Postoperative 1st-month and 1st-year ROE scores of the wide cap group were significantly higher than those in the mini cap group (p<0.05). Preoperative tip projection ratio (Goode) values of the wide cap group were considerably higher than those in the mini cap group (p<0.05). There were no significant differences between tip projection, nasal dorsum length, nasofrontal angle, and nasolabial angle values of the mini cap and wide cap groups (p>0.05). Correlation tests showed that as preoperative ROE scores decreased, postoperative-1st month and 1st-year ROE scores increased (p<0.05). Postoperative 1st-month and postoperative 1st-year's ROE scores increased together (p<0.05). In the wide cap group, postoperative 1st-month and postoperative 1st-year's ROE scores increased compared to the mini cap group (p<0.05). As postoperative 1st-year nasolabial angle values increased, postoperative 1st-year ROE scores also increased (p<0.05). CONCLUSIONS We found that patients who received wide-cap rhinoplasty had increased postoperative ROE scores and higher satisfaction rates during the first month and first year. Postoperative higher nasolabial angle values were related to higher ROE scores and patient satisfaction in the postoperative 1st year.

Abstract
AIM To investigate peripheral and central olfactory pathways using cranial magnetic resonance imaging (MRI) in human immunodeficiency virus (HIV)-infected patients. MATERIALS AND METHODS The cranial MRI images of 37 HIV-infected adult patients and 37 adults without HIV infection having normal cranial MRI results were included in the study. In both groups, olfactory bulb (OB) volume and olfactory sulcus (OS) depth; and insular gyrus and corpus amygdala areas were measured using cranial MRI. In the HIV group, disease duration, HIV RNA, and CD4 lymphocyte count and levels as a percentage were also recorded. RESULTS The HIV group had significantly lower bilateral OB volumes, insular gyrus and corpus amygdala areas compared to the control group. The HIV group showed positive correlations between OB volumes, OS depths, insular gyrus, and corpus amygdala areas bilaterally. Increases in OB volumes and OS depths were associated with an increase in the insular gyrus area. The corpus amygdala and insular gyrus areas increased similarly. There was no significant correlation between age, gender, disease duration, CD4 lymphocyte count and per cent, HIV RNA values, and the measurement values of the central and peripheral olfactory regions. CONCLUSION A decrease in olfactory regions of OB, insular gyrus, and corpus amygdala in HIV-infected patients shows that HIV infection may cause olfactory impairment. There is no correlation between disease duration and olfactory impairment. It may be related to neuroinflammation, HIV-related brain atrophy, acquired immunodeficiency syndrome (AIDS) dementia complex, or neurocognitive impairment, which are the other explanations for the olfactory impairment in HIV. The possible toxicity from antiretroviral therapy (ART) may be another cause that should be investigated further.

Abstract
OBJECTIVE In the present study, we investigated the effects of 2-aminobenzothiazole application on human laryngeal carcinoma cells. MATERIALS AND METHODS Human larynx epidermoid carcinoma (HEp-2) (ATCC® CCL-23™) cells were purchased from American Type Culture Collection (ATCC, USA). Human larynx epidermoid carcinoma HEp-2 cells were cultured in complete Dulbecco's Modified Eagle's Medium (DMEM) supplemented with fetal bovine serum (FBS) (10%) and penicillin/streptomycin (1%) in a CO2 (5%) incubator under standard cell culture conditions. 2-aminobenzothiazole was prepared, and further dilutions ranging from 3.13 to 100 μM were prepared in fresh culture DMEM. HEp-2 cells on 96 well plates were incubated with the prepared dilutions of 2-aminobenzothiazole for 24, 48, and 72 hours. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) test performed cytotoxicity evaluation and viability percentages. The annexin-V staining technique detected 2-aminobenzothiazole-triggered apoptosis of HEp-2 cells. The activated caspases 3/7 on HEp-2 cells after 2-aminobenzothiazole exposure were evaluated with flow cytometric analysis. The membrane potential changing of HEp-2 cells was measured following the Muse™ MitoPotential kit manufacturer instructions. RESULTS MTT cytotoxicity test results showed that the viability of human laryngeal carcinoma cells decreased with an increase in the application of 2-aminobenzothiazole for 24 hours. The highest growth inhibition by 2-aminobenzothiazole for short-term application of 24 hours was detected at the highest concentration of 2-aminobenzothiazole (100 µM). The results underline that the cytotoxic effect of 2-aminobenzothiazole is dose-dependent. Cytotoxicity test results for an application time of 48 hours showed that the cytotoxicity of 2-aminobenzothiazole is dose-dependent on HEp-2 cells. The required dose of 2-aminobenzothiazole to decrease the cell viability to 50 percent has been 9-fold augmented. Annexin-V findings showed that after exposure to IC50 concentration of 2-aminobenzothiazole for 24 hours, HEp-2 cells underwent the early apoptotic stage (25.99%) and late apoptotic (16.69%), whereas 56.93% of the treated cells were alive. Only 0.39% of 2-aminobenzothiazole treated cells were necrotic. All study results showed that 2-aminobenzothiazole triggered apoptosis on HEp-2 cells with a percentage of total apoptotic cells 42.62 compared to untreated HEp-2 cells. Caspase 3/7 activation results showed that only 0.65% of control HEp-2 cells were with activated caspase 3/7, and 99.35% live cells. The analysis data from the Muse cell analyzer revealed that the percentage of cells with intact mitochondrial membranes was 21.30 after 2-aminobenzothiazole application, and 79.9% were cells with depolarized mitochondrial membranes. It has been understood that the depolarization of the inner mitochondrial membrane has been considered a dysfunction in mitochondria as a sign of apoptosis and drug toxicity. CONCLUSIONS Based on all study findings, 2-aminobenzothiazole has cytotoxicity on human laryngeal carcinoma cells in a dose and time-dependent manner. That means that it decreased viability via inducing caspase-dependent apoptosis. Consequently, it was concluded that 2-aminobenzothiazole has good potential to lead to cytotoxicity and apoptosis on human laryngeal carcinoma cells and, after deeper in vitro and in vivo investigations, can be a good candidate for designing anticancer drugs with high efficiency.

Abstract
This narrative review aims to provide an up-to-date definition of local allergic rhinitis (LAR), its classification, mechanisms, comorbidities, recommendations for diagnosis and treatment, and define needs in this area. Both 'PubMed' and 'Science Direct' literature was reviewed systematically, and a manual search for studies not previously encountered in the databases was also carried out. Published studies were identified in PubMed covering the period from 1947 to 2022. The following keyword search strategy was used: (local allergic rhinitis* OR entopy* OR local Immunoglobulin E * OR nasal specific Immunoglobulin E). LAR involves Type 2 nasal inflammation with local IgE and cannot be diagnosed by systemic methods, such as skin prick or blood IgE tests. A nasal allergen challenge is necessary for diagnosis. LAR can respond to usual AR treatments, including allergen specific immunotherapy (AIT). LAR is a novel entity that requires additional investigation in terms of prevalence, proper diagnosis, treatment, and prognosis. The target outcomes and possible benefits of this review are to achieve a consensus for the study and diagnosis of LAR and increase interest in this area.

Abstract
This narrative review paper evaluates the preservation rhinoplasty (PR) technique in all aspects. The literature survey was performed in PubMed, EBSCO, UpToDate, and Proquest Central databases of Kırıkkale University, Google and Google Scholar databases. The advent of the preservation rhinoplasty (PR) approach has led to a radical shift in the mindset surrounding rhinoplasty procedures. K-area (keystone region) loss, lateral cartilage collapse, and nasal stenosis are all avoidable with preservation measures. The nasal bones, the superior lateral cartilage, the quadrilateral cartilage, and the perpendicular blade of the ethmoid meet at the point known as Zone K. The variety of problems that might develop due to carelessness in this area demonstrates the significance of maintaining the nose's stability and structure. The three components of a preservation rhinoplasty (PR) procedure are (1) preserving the scroll ligament complex by elevating the soft tissue envelope (STE) in a subperichondrial-subperiosteal plane, (2) preserving the nasal dorsum without creating an open roof deformity, and (3) preserving the alar cartilages and achieving the desired shape using sutures rather than excision. Dorsal preservation is one of the three components that make up PR. However, the two concepts are not synonymous. PR involves elevating a skin sleeve from the subperichondrial-subperiosteal plane, preserving the osteocartilaginous dorsum, maintaining the alar cartilages with minor excision and using sutures to achieve the desired form.

Abstract
OBJECTIVE In this retrospective and multicentric study, we investigated applied surgical methods in rhinoplasty for crooked nose deformity. PATIENTS AND METHODS The retrospective data for 300 crooked nose deformity cases (191 males and 109 females) were used in our study. Classification of the initial deformities was performed as (1) I-shaped crooked nose deformity, (2) C-shaped crooked nose deformity, (3) Reverse C-shaped crooked nose deformity, and (4) S-shaped crooked nose deformity. As an operation technique, L-strut septoplasty was performed. The applied surgical methods in rhinoplasty to correct the crooked nose are evaluated and classified. RESULTS Our results showed that initial deformities in crooked nose patients were I-shaped crooked nose deformity (34%), C-shaped crooked nose deformity (28%), Reverse C-shaped crooked nose deformity (21.3%), and S-shaped crooked nose deformity (16.7%). L-strut septoplasty was performed, and the results of the applied methods to correct the crooked nose were evaluated and classified. It was noticed that more than one procedure was applied to each case: (1) double-side lateral osteotomy (86.6%), (2) wedge bone resection on one side of the osteotomy (7.3%), (3) single-side lateral osteotomy (6%), (4) symmetric spreader grafts (56%), (5) asymmetric spreader grafts (10.6%), (6) shaving of the transverse wing of dorsal septum (8%), (7) correction of deviated dorsal septum (16.3%), (8) displaced anterior nasal spine (12.6%), (9) clocking suture (dorsal septal rotation suture) (9%), (10) dorsal septal scoring and splinting graft (8.3%), and equalizing lateral cruses (12.6%). CONCLUSIONS I-shaped and C-shaped crooked nose deformities were mainly detected in crooked nose deformity patients. Correcting the crooked nose, double-side lateral osteotomy, and symmetric spreader grafts were the most applied techniques to correct the crooked nose. Other rhinoplasty techniques were also applied to these patients; more than one technique was needed.

Abstract
We reviewed the potential benefits of conchal cartilage or Polydioxanone (PDS) foil-empowered nasal cartilage as caudal septal extension grafts (CSEGs). Research methods included searching online databases such as Google, Google Scholar, PubMed, and Proquest Central at Kırıkkale University. Use terms like "caudal septal extension grafts," "septal extension grafts," "conchal cartilage," and "PDS foil-empowered nasal cartilage" to find related articles. Due to the anchoring of the lower alar cartilage to the nasal septum, the results of a CSEG rhinoplasty are relatively stable over the long term. They can be adjusted independently by the rhinoplasty surgeon. Over time, the skin and soft tissue envelope contract and a downward force for these grafts develops. It allows for independent regulation of projection and rotation, unlike conventional columellar strut procedures and lateral crural steal techniques. Inadequate cartilage may need conchal or costal cartilage, depending on the application and the need for projection and counter rotation. Costal cartilage transplant outperformed conchal cartilage graft in a rabbit model regarding tip projection and angle relapse rate. Three-patient case series show that PDS foil-enhanced nasal cartilage led to septal cartilage loss. However, other research draws a different result, finding that PDS foil-enhanced nasal cartilage prevented growth inhibition in the developing nasal septum following septoplasty, and reduced late problems in animals. The caudal septal extension grafts should prioritize septum cartilage if it is readily available, of adequate size, and with sufficient strength. If this is not possible, PDS foil-enhanced nasal cartilage fragments or conchal cartilage could be used as a backup. PDS foil will maintain the integrity and stability of the implanted cartilage. Due to its strength, stability, and convenient location, conchal cartilage will serve as the second donor site.

Abstract
This paper aims to review biologics in allergic rhinitis (AR). Biologic agents of Omalizumab, Dupilumab, Mepolizumab, Reslizumab, and Benralizumab are reviewed in detail. The search is performed in "Pubmed," "Google," Google Scholar" and EBSCO Academic Search Ultimate (EKUAL) database of Kırıkkale University Library from 2021 to 2000, and randomized and/or placebo-controlled studies, review papers, meta-analysis, and reports are taken into consideration. The search was performed with the keywords of "allergic rhinitis," "biologics," "biologic agents," "Omalizumab," "Dupilumab," "Mepolizumab," "Reslizumab," "Benralizumab," "Anti IgE," "Anti-IL-4/IL-13", "Anti IL-5". Search is also performed in the "U.S. Food and Drug Administration" (FDA) and "European Medicines Agency" (EMA) web systems. Biological agents such as monoclonal antibodies (MAb) in treatment are called biological therapy or biotherapy. Omalizumab is a humanized Anti-IgE monoclonal antibody. Omalizumab treatment improved the Daily Nasal Rescue Medication Score (DNSSS) and decreased the use of antiallergic drugs in seasonal and perennial AR and rhino-conjunctivitis. Omalizumab is also used in specific immunotherapy patients with allergic rhinitis and reduced allergic reactions associated with allergen immunotherapy, such as anaphylaxis. Dupilumab is an Anti-IL-4/IL-13 biologic agent. Dupilumab treatment significantly improved sino-nasal Outcome Test (SNOT-22) total scores in perennial allergic rhinitis. Anti-IL-5 monoclonal antibodies of Mepolizumab, Reslizumab Benralizumab reduce the number of eosinophils in the blood and tissue, corticosteroid addiction and asthma attacks are reduced, and their use in the treatment of severe eosinophilic asthma has been approved. Biologics, especially Omalizumab, and Dupilumab, may be used more in allergic rhinitis.

Abstract
OBJECTIVE In the present study, we investigated the effects of Ceramide C2 application on human laryngeal carcinoma cells. MATERIALS AND METHODS Human larynx epidermoid carcinoma HEp-2 (ATCC® CCL-23™) cells were purchased from the American Type Culture Collection (ATCC, USA). Human larynx epidermoid carcinoma HEp-2 cells were cultured in complete Dulbecco's Modified Eagle's Medium (DMEM) supplemented with fetal bovine serum (FBS) (10%) and penicillin/streptomycin (1%) in a CO2 (5%) incubator under standard cell culture conditions. Ceramide C2 was prepared, and further dilutions ranging from 3.13 to 100 μM were prepared in a fresh culture medium. Cells on 96 well plates were exposed to the prepared concentrations of ceramide C2 for 24 and 48 hours. Cytotoxicity evaluation was performed by MTT. Apoptosis profiles of HEp-2 cells were detected by annexin-V analysis. The activated caspases 3/7 on HEp-2 cells after ceramide C2 exposure were evaluated with flow cytometric analysis. The morphological changes on HEp-2 cells caused by ceramide C2 were evaluated by staining with phalloidine and acridine orange via confocal microscopy. For the Wound Healing Assay, HEp-2 cells were cultured in 6 well-plates until they became confluent. RESULTS MTT cytotoxicity test findings revealed that the viability of human laryngeal carcinoma cells decreased with the increased application of ceramide C2 for 24 hours compared to untreated (control) cells. The highest growth inhibition by ceramide C2 for short-term application for 24 hours was detected at the highest concentration of ceramide C2 (100 µM). Annexin-V findings showed that 98.97 of HEp-2 cells were alive, and 1.63% were detected as early apoptosis for the control group. The results showed that ceramide C2 triggered apoptosis on HEp-2 cells with a percentage of total apoptotic cells of 61,40 compared to untreated HEp-2 cells. Cysteine proteases (caspases) 3/7 activation percentages of HEp-2 cells exposed to ceramide C2 for 24 hours were compared to control cells, and the morphology of HEp-2 cells was changed with clear apoptotic signs that underlined the cytotoxicity and pro-apoptotic activity of ceramide C2. Scratch Assay assessed the migration capability of HEp-2 cells before and after the exposure to ceramide C2. It showed that ceramide C2 reduced human laryngeal carcinoma cells' migration capability and proliferation for 24 hours. CONCLUSIONS Based on all study findings, it can be considered that short-chain ceramide C2 exerted cytotoxicity on human laryngeal carcinoma cells in a dose and time-dependent manner and reduced the viability via inducing caspase-dependent apoptosis. The overall effect might be derived from the elevated intracellular ceramide levels by the exogenous application of ceramide C2. Consequently, it was concluded that ceramide C2 has good potential to cause cytotoxicity and apoptosis in human laryngeal carcinoma cells and, after deeper in vitro and in vivo investigations, can be a good candidate for designing anti-cancer drugs with high efficiency.

Abstract
In the present study, we reviewed the efficacy of traditional herbal formulas on human immunity. A literature survey was performed in PubMed, UpToDate, Proquest Central Databases of Kırıkkale University, Google and Google Scholar databases from the internet. Search key words were "immune", "immune system", "herbal", "Pelargonium Sidoides", "Echinacea Purpurea", "Sambucus Nigra", "Beta Glucan", "Vitamin C", "Zinc". The immune system is a natural self-defense mechanism made up of cells that assist the body in distinguishing between self and non-self-molecules. All immune system components must be regularly modified in order to keep the body defenses up against the ever-evolving microbes that are constantly looking for new ways to attack the host. A Chinese herbal formulation is a combination of several herbs. The practitioner begins with one or two major substances that are intended to treat the ailment. The reproducibility of the efficacy of herbal medicines is dependent on the consistency of the quality of each unique raw herb. Pelargonium Sidoides, Echinacea Purpurea, Sambucus Nigra, Beta Glucan, Vitamin C, and Zinc are some herbal treatments utilized for their benefits on human immunity. Herbal remedies are undoubtedly valuable in boosting impaired immune function, particularly where damage has occurred due to malnutrition, chronic disease or previous infections. At present, however, an invincible immune system remains firmly in the realm of fantasy.

Abstract
OBJECTIVE We investigated the effects of tannic acid on viability and proliferation of nasal cells after topical application. It was also evaluated whether tannic acid served as an alternative treatment agent. MATERIALS AND METHODS Collected primary nasal epithelium from healthy people who had undergone septoplasty operations were incubated in cell culture. Following the implementation of 2.5 µM tannic acid in cultured cells, both the number of total cells and their viability were measured using the trypan blue assay, while proliferation was assessed through the XTT method. The XTT method, which involves using "2,3-bis-(2-methoxy-4-nitro-5-sulphophenyl)-2H-tetrazolium-5-carboxanilide", is a reliable means of determining cellular toxicity. RESULTS XTT experiment results showed that there was no harm was detected to nasal cells after tannic acid's topical implementation. There were no significant changes in cell proliferation; moreover, no matter what the doses were. Additionally, no cytotoxic effects were detected on nasal cells' primary culture at "the end of the 24 hours of implementation". There was no side effect of it, either. CONCLUSIONS According to the research, the application of tannic acid topically did not result in any harmful effects on the nasal cell culture. Tannic acid's potential anti-inflammatory properties and its ability to decrease Th2-related cytokines suggest that it may be beneficial for patients with rhinosinusitis or allergic rhinitis, pending confirmation through clinical trials. Additionally, if clinical trials confirm its effectiveness, tannic acid may be useful in healing wounds for patients undergoing septorhinoplasty.

Abstract
OBJECTIVE The study aims to define butterbur's impact on nasal cells' viability and proliferation. After topically administering butterbur to the nasal epithelial cells, research has been done to see if butterbur has any harmful effect on the nasal cells. MATERIALS AND METHODS Specimens of healthy primary nasal epithelium were collected from the subjects and incubated in cell culture in due course of septoplasty. After implementing 2.5 µM butterbur in cultured cells, cell viability was defined via trypan blue assay, and proliferation was defined via the XTT method. The number of total cells, viability, and proliferation was defined. XTT (2, 3-bis-(2-methoxy-4-nitro-5-sulphophenyl)-2H-tetrazolium-5-carboxanilide) experiments can be used to evaluate cellular toxicity. RESULTS The findings of the XTT experiment reveal no harm to nasal cells after topical implementation of butterbur. No significant change in the proliferation of the cells, no matter what the doses are. There was no cytotoxic effect on the primary nasal cells at the end of 24 hours of implementation, and no side effects were found. There was no difference in cells' viability between the experimental group with butterbur application and the control group. CONCLUSIONS Cytotoxicity on nasal cells was not observed after the butterbur application. Even if there have been some indications of liver toxicity, butterbur can be suggested as a safe option for seasonal allergic rhinitis. Further studies related to the toxicity of topical butterbur are also recommended, even though this study indicates no cytotoxicity from the topical application on nasal cells.

Abstract
OBJECTIVE We investigated the role of matrix metalloproteinase-2 (MMP-2) and MMP-9 in nasal polyp (NP) pathogenesis. PATIENTS AND METHODS In group 1 (n = 24), polyp specimens were obtained from maxillary sinus, ethmoid sinus, and nasal cavity. In group 2 without NP (control) (n = 11), inferior turbinate samples were taken. Inflammatory cell count and MMP2, MMP9 and tissue inhibitor of metalloproteinase-1 (TIMP-1), positivity indexes (PIs) were evaluated. RESULTS Granulocyte and mast cell-MMP2 and MMP9-PI were higher than the rate of monocyte-MMP2-PI and monocyte-MMP9-PI, respectively, in the ethmoid sinus, maxillary sinus, and nasal cavity. Mast Cell-TIMP1-PI was higher than the rates of granulocyte-TIMP1-PI and monocyte-TIMP1-PI in the maxillary sinus and was higher than the rate of monocyte-TIMP1-PI in the ethmoid sinus. CONCLUSIONS Excessive MMP2 and MMP9, compared to TIMP1, are present in granulocytes and mast cells, respectively. With matrix MMPs, the extracellular matrix is destroyed, leading inflammatory cells to pass through, causing polypoid degeneration.

Abstract
OBJECTIVE In the present study, we investigated the efficacy of morphing technology via Adobe PhotoShop program and its "liquefy" effect in patients planned to undergo augmentation rhinoplasty. PATIENTS AND METHODS The retrospective data for 100 consecutive augmentation rhinoplasty cases (64 females and 36 males) were enrolled in our study. Preoperative computer imaging (PCI) steps, a stepwise systematic guide for image editing, including (1) augmenting the dorsum, (2) lengthening the nose, (3) adjusting the tip projection, (4) perfection of the nasal dorsum and (5) exaggerating the tip projection and/or the dorsal augmentation were applied to the patients. After performing the PCI before augmentation rhinoplasty, the patients were allowed to see the options for the final appearance of their noses. Therefore, PCI helped them to decide on their operations. RESULTS After applying CS-PCI before augmentation rhinoplasty, 71 patients (71%) accepted Step-4, and 19 (19%) accepted Step-3. Furthermore, six patients (6%) requested additional changes during their operational planning. In 95% of the cases, the authors achieved the results agreed upon based on the preoperative simulation. CONCLUSIONS By PCI involving five steps for augmentation rhinoplasty, the patients were allowed to see the options for the final appearance of their noses. Therefore, PCI helped them to decide on their operations. With the help of morphing technology (2D), it is possible to increase interpersonal communication effectively.

Abstract
OBJECTIVE The aim of this study was to investigate central smell centers with cranial magnetic resonance imaging (MRI) diffusion-weighted imaging (DWI) in COVID-19. PATIENTS AND METHODS This retrospective study evaluated cranial MRI images of 54 adults. The experimental group (Group 1), consisting of 27 patients with positive COVID-19 real-time polymerase chain reaction (RT-PCR) assays, was compared to the control group (Group 2), comprising 27 healthy controls without COVID-19. The apparent diffusion coefficient (ADC) values were measured in the corpus amygdala, thalamus, and insular gyrus in both groups. RESULTS Thalamus ADC values of the COVID-19 group were significantly lower compared to the control group bilaterally. However, no differences were found in the insular gyrus and corpus amygdala ADC values between the two groups. Positive correlations were observed between the insular gyrus and corpus amygdala ADC values and the thalamus ADC values. Insular gyrus ADC values (right) were higher in females. Left insular gyrus and corpus amygdala ADC values were higher in COVID-19 patients with smell loss. Right insular gyrus and left corpus amygdala ADC values were lower in COVID-19 patients with lymphopenia. CONCLUSIONS Diffusion restriction in olfactory areas can be considered an obvious indicator that the COVID-19 virus affects and damages the immune system at the neuronal level. Given the urgency and lethality of the current pandemic, acute onset odor loss should be considered a high suspicion-adhesive index for patients with SARS-CoV-2 infection. Therefore, the sense of smell should be considered and evaluated simultaneously with other neurological symptoms. DWI should be widely used as an early imaging method for central nervous system (CNS) infections, especially in relation to COVID-19.

Abstract
OBJECTIVE In our study, we showed that the septal extension graft (SEG) technique, which we applied for nasal projection in rhinoplasty surgery, increases the tension of the lateral cartilage (LC) and alar structures. We also demonstrated that nasal congestion could be treated by applying this technique in patients with nasal obstruction due to bilateral dynamic alar collapse. PATIENTS AND METHODS This study was conducted retrospectively on 23 patients with nasal obstruction due to alar collapse. Bilateral dynamic nasal collapse and (+) Cottle test was present in all patients. Nasal lateral wall tissue was also found flaccid on nasal palpation and collapsed to the extent of obstruction on deep inspiration. Standard septal extension graft (SEG) and tongue-in-groove techniques were applied to all patients. RESULTS Septal cartilage was used for SEG in all patients. No complaints of nasal obstruction on deep inspiration were noted by the patients at six months postoperative follow-up, and Cottle tests were negative. The patients' mean respiratory score was 152 postoperatively, compared to 66.5 preoperatively. This difference was statistically significant using the Wilcoxon signed ranks test (p<0.001). In evaluating postoperative cosmetic appearance due to nasal tip projection (NTP) and cephalic rotation changes, 16 men and four women reported that it was better, while two men felt that there was no change. One woman reported that her cosmetic appearance was worse than before; a revision surgery was performed for her at seven months postoperatively. CONCLUSIONS This method is effective for patients with bilateral nasal collapse and thick-short columella. With the applied surgery, the caudal edge of the LC diverges from the septum, alar region tension and resistance increase, the columella increases in length, nasal projection increases, and the vestibule cross-sectional area is enlarged. In this way, a significant increase in nasal vestibular volume was obtained.

Abstract
OBJECTIVE We studied the cytotoxic effects of topical anise oil on NIH/3T3 fibroblast cells using a cell culture assay. MATERIALS AND METHODS NIH/3T3 fibroblast cells were grown in Dulbecco's Modified Eagle Medium (DMEM) supplemented with fetal bovine serum (10%) and penicillin/streptomycin under standard cell culture conditions in a humidified incubator containing 5% carbon dioxide. For the MTT cytotoxicity experiment, NIH/3T3 cells were plated in triplicate at a concentration of 3x103 per well in 96-well plates and incubated for 24 hours. The cells were treated with anise oil concentrations ranging from 3.13 to 100 μM, and the plates were cultured for 24, 48, and 72 hours under standard cell culture conditions. For assessment by confocal microscopy, NIH/3T3 cells were seeded on sterilized coverslips in 6-well plates at a concentration of 105 cells per well in triplicate. For 24 hours, cells were treated with 100 μM of anise oil. Three wells that were not treated with anise oil served as the control group. RESULTS The MTT findings demonstrated that anise oil is not cytotoxic to NIH/3T3 fibroblast cells. Anise oil stimulated cell growth and triggered cell division at all three incubation intervals of 24, 48, and 72 hours. The maximum growth was obtained in the applied highest concentration of 100 μM anise oil. At doses of 25, 50, and 100 μM, there was also a statistically significant improvement in cell viability. At 72 hours of incubation, dosages of 6.25 and 12.5 micro of anise oil were shown to be viability-inducing for NIH/3T3 cells. In the confocal microscopy pictures, it was found that anise oil was not cytotoxic on NIH/3T3 cells at the applied maximal dose. The experimental group of NIH/3T3 cells exhibited the same cell morphology as the untreated control group. In both sets of NIH/3T3 cells, the nucleus was round and undamaged, and the cytoskeleton was determined to be compact. CONCLUSIONS Anise oil is not cytotoxic on NIH/3T3 fibroblast cells and initiates cell growth. Anise oil could be used topically to enhance wound healing after surgical procedures if clinical trials will confirm experimental data.

Abstract
OBJECTIVE This study evaluated olfactory function in patients undergoing hemodialysis. The evaluation utilized the Sniffin' Sticks test. PATIENTS AND METHODS The study enrolled 56 individuals undergoing hemodialysis for chronic renal failure alongside 54 healthy controls. The Sniffin' Sticks battery was used to assess olfactory function in all subjects. The battery included 12 separately identifiable odors. A score below 6 was considered anosmia, whilst scores ranging from 7 to 10 were classed as hyposmia. A score of at least 11 indicated normal olfaction. RESULTS There was a statistically significant difference in scores between the two groups. The hemodialysis patients scored 9.12±2.77 compared to 10.72±1.94 in the controls. In the hemodialysis patients, scores for males and females did not differ significantly. Furthermore, there was no correlation between score and age, sex or length of renal failure. Some 12.5% of hemodialysis patients were anosmic, whilst 50% were hyposmic. The corresponding rates in the control group were 7.4% and 20.4%. CONCLUSIONS Undergoing hemodialysis is associated with a decreased total score on the Sniffin' Sticks battery, with anosmia in 12.5% of patients and hyposmia in 50.0%. Thus, olfactory impairment is present in 62.5% of hemodialysis patients. According to previous research, renal transplantation results in an improved ability to smell, depending on how plastic the neurons involved in olfaction are.

Abstract
OBJECTIVE The aim of this paper is to investigate the efficacy of filler applications which were evaluated in terms of nasal deformity and quality of life of the patients, and to review the fillers around the nose. PATIENTS AND METHODS Forty patients who underwent filler application were included into the study and were divided into Group 1 (Deep Radix), Group 2 (Minor irregularities due to rhinoplasty), Group 3 (Shallow dorsum) and Group 4 (Dorsal irregularity). There were 10 patients in each of the groups. In all groups, nasal deformity score was evaluated with a 1 to 5 scale as following: 1- No deformity, 2- Hardly visible deformity, 3- Visible deformity, 4- Moderate deformity, 5- Apparent deformity. Quality of life was evaluated by a 1 to 10 scale, 1 showing very low and 10 showing very high. RESULTS Our results showed that there were statistically significant improvements (decreased) in nasal deformity evaluation scores after the procedure compared to the before the procedure scores in Group 1 (Deep Radix), Group 3 (Shallow dorsum) and Group 4 (Dorsal irregularity) (p<0.05) However in Group 2 (Minor irregularities due to rhinoplasty), there were no significant differences between the nasal deformity evaluation scores after and before the procedure (p>0.05). For nasal deformity evaluation after the procedure, Group 1 (Deep Radix), Group 3 (Shallow dorsum) and Group 4 (Dorsal irregularity) scores were significantly lower (better) than Group 2 (Minor irregularities due to rhinoplasty) scores (padjusted <0.0125). In all four groups (Deep Radix, Minor irregularities due to rhinoplasty, Shallow dorsum, Dorsal irregularity), quality of life scores were significantly improved (increased) after the procedure compared to before the procedure (p<0.05). For Quality of life (VAS) before the procedure, Group 3 (Shallow dorsum) scores were significantly higher (improved, increased) than Group 1 (Deep Radix) and Group 4 (Dorsal irregularity) (padjusted <0.0125). CONCLUSIONS Filler applications improved (decreased) nasal deformity evaluation scores and improved (increased) quality of life scores. Fillers can be applied for deep radix, minor irregularities due to rhinoplasty, shallow dorsum and dorsal irregularity. It is essential to choose carefully appropriate materials and procedures for patients to obtain optimum results.

Abstract
OBJECTIVE This study aimed to define the impacts of curcumin on nasal cell viability and proliferation. MATERIALS AND METHODS Specimens of healthy primary nasal epithelium were collected and incubated in cell culture during septorhinoplasty from people who signed a consent form. After implementing 2.5 µM curcumin in cultured cells, cell viability was defined via trypan blue assay, and proliferation was defined via the XTT method. The number of total cells, viability, and proliferation was defined. XTT (2,3-bis-(2-methoxy-4-nitro-5-sulphophenyl)-2H-tetrazolium-5-carboxanilide) experiments can be used to evaluate cellular toxicity. RESULTS The results revealed no harm to nasal cells after the topical implementation of curcumin. There was no significant change in the proliferation of the cells related to 24 hours of implementation. There was no adverse effect of using curcumin on the cell viability, either. CONCLUSIONS No cytotoxic effect on nasal cells has been observed after applying topically implemented curcumin. Curcumin could be used topically for an alternative treatment for allergic rhinitis as it has anti-inflammatory and immune response modulatory effects if clinical trials will confirm experimental data.

Abstract
OBJECTIVE We aimed to offer a new preservation strategy for dehumping the dorsum by using a variation of the cartilage push-down (Ishida) technique. PATIENTS AND METHODS Three hundred patients (42 males and 258 females) had surgical procedures. All procedures were closed-surgery-type, primary-case procedures performed through a closed incision. Low cartilaginous septal strip resection was performed on 269 individuals, whereas high septal strip resection was performed on the remaining 31 patients. The bony cap is shielded as a separate unit and preserved, so protected from any potential damage. The cartilage roof is separated from the bone roof and lowered while wearing the bony cap component. As a result, less concealment is required. However, it is ineffective on dorsal profiles that are sharp or S-shaped, as opposed to flat. Thus, the modified cartilage push-down with bony cap rasping procedure can be carried out. The sharp hump on the bony crown of the skull is smoothed out and filled. Therefore, the bony cap above the central cartilage roof is much thinner. Because the hump is less likely to appear again, concealment is unnecessary. A median of 8.5 months was spent following-up (6-14 months). RESULTS According to our method, among men (n=42), the hump size ranged from minor (n=5) to medium (n=25) to big (n=12). There were 258 women, 88 of whom had a little hump, 160 had a medium hump, and 10 had a huge hump. Indicative of surgeon satisfaction with low cartilaginous septal strip excision vs. high septal strip resection include the following: with a total of 269 patients, 35 males, and 234 females had low cartilaginous septal strip resections, with 98 and 96% success rates, respectively, for the surgeons. There were 31 patients, seven men and 24 women, who all underwent high septal strip resections, with a 98% and 96% success rate for the surgeons. It was found that there was a correlation between the size of the hump and the level of satisfaction felt by its bearers. Rates of male satisfaction with humps ranged from 100% for little humps to 100% for medium humps to 99% for huge humps. Satisfaction percentages among women ranged from 98% in the case of little humps to 96% among medium humps and 95% among large humps. CONCLUSIONS Our technique of modification of the cartilage push-down (Ishida)1 method is applied for dehumping the dorsum. High satisfaction percentages were obtained from the patients and surgeons. This technique may be a good option for patients who need dehumping.

Abstract
OBJECTIVE Through a cell culture test, we analyzed the cytotoxic effects of topical spiramycin on NIH/3T3 fibroblast cells. MATERIALS AND METHODS Dulbecco's Modified Eagle Medium (DMEM) supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin was used for the growth of NIH/3T3 fibroblast cells in a 5% CO2 incubator. Spiramycin's cytotoxicity was measured using the MTT assay. 5,000 NIH/3T3 cells per well of a 96-well plate were seeded in each well, and the cells were treated with spiramycin (3.13-100 μM) for 24, 48 and 72 hours while the plates were incubated at 37°C in a humidified 5% CO2 atmosphere. First, 105 NIH/3T3 cells were seeded onto coverslips in 6-well plates for morphological analysis of both untreated and spiramycin-treated cells. For 24 hours, NIH/3T3 cells were exposed to a 100 μM dosage of spiramycin. The cells in the control group were grown in complete growth media alone. RESULTS Spiramycin was non-toxic to NIH/3T3 fibroblast cells in a MTT test. The concentration of spiramycin used to stimulate cell growth increased as the concentration was increased. After 24 and 48 hours of treatment with 100 μM NIH/3T3, the cells showed the most significant increase in size. Cell viability was shown to be significantly reduced at spiramycin doses of 50 and 100 μM. All MTT findings revealed that spiramycin enhanced cell viability and was not harmful to the fibroblast cells for short-term application of 24 and 48 hours but lowered the viability of fibroblast cells at the doses of 50 and 100 μM for long-term application duration of 72 hours. Confocal micrographs showed that spiramycin treatment did not affect the cytoskeleton or nucleus of fibroblast cells, in contrast to the control NIH/3T3 cells. Both untreated and treated with spiramycin, fibroblast cells were found to be fusiform and compact, with their nuclei remaining unaltered and unreduced in size. CONCLUSIONS It was concluded that spiramycin has a beneficial effect on fibroblast cells and is safe for use over short periods. Spiramycin reduced fibroblast cell viability when applied for 72 hours. Confocal micrographs showed that fibroblast cell skeletons and nuclei were unharmed and undamaged, that cell shapes were fusiform and compact, and that nuclei were neither broken nor shrunken. Topical spiramycin could be recommended for septorhinoplasty procedures due to anti-inflammatory effects for short-term usage if clinical trials will confirm experimental data.

Abstract
OBJECTIVE In the present study, we investigated the topical bromelain's cytotoxic effects on mouse fibroblast NIH/3T3 cells via cell culture study. MATERIALS AND METHODS In this cell culture study, Dulbecco's Modified Eagle Medium (DMEM) with fetal bovine serum (FBS, 10%) and penicillin/streptomycin (1%) was used as a cell growth medium for NIH/3T3 mouse fibroblast cells. MTT test was performed in 96-well plates seeded with NIH/3T3 cells 5x103/well and under standard cell culture conditions. Bromelain doses of 3.13 to 100 μM were administered to the wells and incubated for 24, 48, and 72 hours in the same cell culture conditions. For Confocal microscopic evaluation, NIH/3T3 cells were plated on cover slips in 6-well plates (105 cells/well) and treated with 100 μM concentration of bromelain for 24 h. Untreated cells were used as controls. RESULTS MTT results showed that bromelain is not cytotoxic on mouse fibroblast NIH/3T3 cells. All three incubation times of 24, 48, and 72 hours bromelain initiated cell growth. A statistically significant rise in cell growth was detected in the only applied highest dose of 100 μM bromelain for all incubation times except for 24 hours. The nontoxic effect was further investigated by using confocal microscopy by applying the highest bromelain dose of 100 μM to NIH/3T3 mouse fibroblast cells. Confocal micrographs showed that bromelain did not change the morphology of mouse fibroblast cells at the incubation time of 24h. In untreated cells and bromelain-treated cells, the nucleus of NIH/3T3 cells was undamaged and compact, and the cytoskeleton was fusiform and non-fragmented. CONCLUSIONS Bromelain is not cytotoxic on mouse fibroblast NIH/3T3 cells and enhances cell growth. If clinical trials will confirm this, it is possible that bromelain will be used topically in humans to enhance wound healing, in rhinosinusitis and chronic rhinosinusitis with nasal polyps and endonasal surgeries due to its anti-inflammatory effects.

Abstract
OBJECTIVE Dexpanthenol is an ingredient in multiple topical pharmaceutical preparations thanks to its high penetration and localized concentration. It is included in many ointments or lotions for dermatological use, assisting in healing and reducing pruritus. Vaseline is a synthetic product obtained by distilling crude oil. It is commercially available in several grades. The study presented here examined how topically applied agents (dexpanthenol or vaseline) affect nasal epithelial cells in culture. In particular, the study aimed to identify any alterations to epithelial cells which might indicate toxicity. MATERIALS AND METHODS The nasal epithelial cells used were sourced from mucosal tissue fragments left over the following septorhinoplasty on five patients not suffering from rhinosinusitis. The first step was to dissect the mucosal fragments into smaller pieces on a sterilized Petri dish. These fragments were then placed into the DMEM-F12 cell culture medium, which had been freshly prepared. The dexpanthenol and vaseline were diluted in dimethylsulfoxide (DMSO) to a concentration of 5 mg/mL. The cells in the wells were exposed to varying concentrations of dexpanthenol or vaseline. The actual concentration of the test reagent to which the epithelial cells were exposed ranged from 0.15 mg/mL to 5 mg/mL. The exposure period was 24 hours. The cells were finally examined using a Leica SP5II confocal microscope. The features sought were DNA fragmentation, condensation of the nuclei, changes in the outer membrane, or cytoskeletal abnormality. These features, if present, indicate cytotoxicity. RESULTS The viability of the cultured nasal epithelial cells was unaltered by a 24-hour exposure to dexpanthenol, nor was the cellular proliferation rate affected at the level of statistical significance. There was evidence of a cytotoxic effect from exposing nasal epithelial cells to vaseline in liquid form for 24 hours. There was a reduction in cellular viability in the plates where the highest dose of vaseline (5 mg/mL) was used. Cellular viability was not affected significantly at any of the doses below 5 mg/mL. CONCLUSIONS The absence of cytotoxic effects from the application of dexpanthenol to the nasal mucosa indicates that this agent may be safely used within the nose. The cytotoxic effects of liquid vaseline observed in this trial (condensed nuclear chromatin, loss of cellular volume) indicate that this agent may be harmful when used intranasally. For patients who require nasal packing due to nose bleeds or following endoscopic sinus surgical procedures, dexpanthenol should be preferred to vaseline from the point of view of maximizing healing of a nasal injury.

Abstract
OBJECTIVE We aimed to create an ideal ointment combination to provide fast wound healing with the highest patient comfort after nasal surgery and nasal flap surgery. MATERIALS AND METHODS Twenty-one male Wistar rats were included. The flap survival method was used. The rats' healing process was evaluated in all groups. After having the same surgical procedure, the following ointments were applied to flap borders twice a day for seven days in each of the groups. In group 1 (Control, n=7), Dexpanthenol 5% (Dex); in group 2, Dex, Ciprofloxacin 0.5 % (Cip) and Ephedrine hydrochloride 1% (Eph); in group 3, Dex+Cip+Eph and Ketoprofen 2.5% (Ket) was applied. On the seventh postoperative day, the size of the necrosis on the flap was evaluated. RESULTS Median necrotic areas on skin flaps were 36.00% sq mm in group 1, 23.00% sq mm in group 2, and 5.00% sq mm in group 3. Flap necrosis areas on skin flaps were group 3 <group 2 <group 1 (p adjusted <0.0175). The necrosis areas of groups 2 and 3 were significantly lower than the control group, and the necrosis areas of group 3 were significantly lower than group 2 (p adjusted <0.0175). CONCLUSIONS For the postoperative healing process and to prevent flap necrosis, the Dex+Cip+Eph+Ket combination was recommended in the first order. Dex+Cip+Eph combination also reduced skin necrosis in the flaps as the second order. Only Dex treatment is not enough for the completion of the healing process. The best results were provided by the Dex+Cip+Eph+Ket combination and recommended its usage after septorhinoplasty surgeries or nasal flap surgeries to prevent flap necrosis.

Abstract
The aim of this paper is to review intranasal trigeminal system and associated reflexes. The literature survey was performed on PubMed, ProQuest Central database of Kirikkale University and Google Scholar. The intranasal trigeminal system and associated reflexes play an important role in humans in both health and disease, including in rhinitis of non-allergic and mixed type. The intranasal trigeminal nerve provides sensory perception to the lining of the nose, supplying information on how patent the nasal airway is and responding to various chemical signals. The reflexes known to exist within the intranasal trigeminal system are nasobronchial reflex, trigemino-cardiac reflex, nasogastric reflex, and nasal cycle. The intranasal trigeminal system and its reflexes play a vital role in normal human physiology. Alterations in how this system operates may underlie multiple forms of rhinitis and more research is needed to fully understand the mechanisms involved.

Abstract
OBJECTIVE The objective of the study was to evaluate the effect of ketoprofen when locally applied to tissue-cultured nasal epithelium. MATERIALS AND METHODS Healthy primary nasal epithelial cells were grown in a tissue culture medium. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay was used to evaluate cytotoxicity. Markers of cellular injury revealed by the MTT assay include fragmentation of DNA, condensed nuclei, and changes affecting the cellular outer membrane and cytoskeleton. Epithelial cells at body temperature in cell culture were exposed over a 24-hour period to ketoprofen. Following the MTT assay, the confocal microscopic examination was performed. The extent to which epithelial cells remained capable of proliferating was evaluated by inducing a scratch injury, waiting for the repair to occur, and then examining the result with the ordinary light microscope. RESULTS Topically applied ketoprofen does not affect the viability of tissue-cultured nasal epithelial cells within a 24-hour period. Furthermore, there were no cellular morphological alterations observed which would indicate toxicity from ketoprofen. In the scratch assay, the cells regained a normal confluent appearance within 24 hours. Thus, ketoprofen neither increases nor alters the rate at which nasal epithelial cells proliferate. CONCLUSIONS Ketoprofen, when applied topically for 24 hours to nasal epithelial cells in cell culture, does not cause any alterations in cellular appearance which would suggest impairment of the ability to proliferate or indicate a cytotoxic effect. Extrapolating from these results, it appears acceptable to use ketoprofen topically within the nose in cases of rhinosinusitis (acute or chronic) or nasal pain since there is minimal risk of local toxic injury.

Abstract
OBJECTIVE The objective of this research was to examine the effects of topical ciprofloxacin on cultured nasal epithelial cells of human origin. MATERIALS AND METHODS Human nasal epithelial cells were collected from patients who voluntarily donated tissue left over following septorhinoplasty. The samples were from individuals without any indication of rhinosinusitis. An assay that may be employed to investigate toxic effects at the cellular level is MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide). This test reveals where DNA becomes fragmented, the nuclei condense, the outer cell membrane is altered, or the cytoskeleton appears disrupted. The present study employed this technique. Nasal epithelium in cell culture was exposed to ciprofloxacin for 24 hours at a temperature of 37°C, following which the MTT assay was undertaken before examining the cells by confocal microscopy to look for alterations indicating cytotoxicity. Another test of toxicity, the artificial scratch technique, was also used. Cells treated in this way were assessed using a light microscope. RESULTS The nasal epithelial cells in culture that were exposed to topical ciprofloxacin for 24 hours were less viable than controls and this result was statistically significant. For this length of exposure, the IC50 was calculated as 1.565 mg/mL. The peak reductions in cellular viability occurred with exposure at a concentration of 1.25 mg/mL and 0.625 mg/mL. These was only a mild decrease in viability at other concentrations, but these results were of statistical significance. The MTT assay and confocal microscopy confirmed this result. Cultured nasal epithelium not exposed to ciprofloxacin (i.e., controls) exhibited a compact morphological appearance when examined with confocal microscopy. The epithelial cells had a regular fusiform boundary, and the nuclei were intact. By contrast, the cultures with exposure to the antibiotic were of decreased size and their outline changed from fusiform to round. The epithelial cells cultures where scratch injury was induced were examined by light microscopy, the extent of closure of the denuded area being assessed after 24 hours. It was noted that the area opened up by the experimental scratch was not closed completely by 24 hours later. This result shows that ciprofloxacin decreases the viability of nasal epithelial cells. CONCLUSIONS Topical application of ciprofloxacin to the nasal lining is not recommended, since this resulted in decreased cellular viability, cellular shrinking and alteration in outline from fusiform to round in cultured nasal epithelial cells. These changes indicate that topically applied ciprofloxacin is toxic to nasal epithelial cells. The outcomes of this study should be studied and correlated in vivo models.

Abstract
OBJECTIVE In our study we aimed to evaluate the effects of applying propolis topically to epithelial cells of the nasal cells, to discover whether this causes any toxic effect upon the cells. MATERIALS AND METHODS Samples of healthy human primary nasal epithelium harvested during septoplasty from volunteers were incubated in cell culture. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assays may be utilized when assessing cellular damage (toxicity), as evidenced by DNA fragmentation, nuclear condensation, alteration in the outer plasma membrane and cytoskeletal alteration. This was the method used in the study. Cultured epithelial cells were incubated with propolis (Bee&You) for 24 hours at 37°C. The MTT assay was then performed, and the cell morphology was examined by confocal microscopy. In addition, via wound healing assay, cellular proliferation was assessed by the artificial scratch method followed by light microscopy. RESULTS MTT assay results showed that the primary nasal cells were not affected by the topical application of propolis for 24 hours. All of the applied doses not changed significantly the viability of the cells. The agent was not found to be cytotoxic to the primary nasal cells in the application time of 24 hours. Our confocal microscopy findings supported the MTT findings. According to the confocal images, control cells that were not treated with test agent were with compact morphology and undamaged fusiform cell shape and nucleus. In test group of nasal cells, Propolis was found not to be cytotoxic on the cellular morphology and not changed the cells. When evaluating the results from the wound healing assay, the clear area of scratch obtained at the start of incubation (0th) was closed totally with the proliferated primary nasal cells after incubation of 24 hours with propolis. These findings are supported by our MTT findings that imply to the slight induce of proliferation of the primary cells by Propolis. CONCLUSIONS Topically applied propolis did not have a cytotoxic effect on nasal epithelium cells. Considering its antibacterial and antioxidant effects, it has been concluded that topical application in sinonasal inflammatory diseases (e.g., acute and chronic rhinosinusitis) may have an auxiliary effect in treatment. Moreover, there is a slight induce of proliferation of the primary cells by propolis which may help wound healing in septal surgeries and epistaxis.

Abstract
The aim of this paper is to review mechanisms and solutions for nasal drug delivery. Literature survey was performed via PubMed, Google Scholar, Google, and ProQuest Central database of Kirikkale University. The nasal lining presents a large area of endothelium of variable permeability and with a rich vascular supply. Advantages of this route include eliminating first-pass metabolism and being easily accessible. The nasal route enables some agents which are otherwise difficult to administer to enter the systemic circulation, for example, low molecular mass compounds with high polarity, peptides, or proteins. There are three principal factors that influence the extent to which drugs can be absorbed through the nasal lining, namely the physico-chemical characteristics of the drug molecule itself, the action of the mucociliary system within the nose, and the presence of any factors increasing nasal absorption. A key factor limiting the use of the intranasal route of administration is insufficient absorption through the nasal mucosa. A number of drugs in development cannot be administered intranasally because their bioavailability following nasal administration is too low. There has been considerable research focus on methods to enhance absorption via the nasal mucosa. In this chapter, we review the literature related to this problem and discuss potential solutions.

Abstract
OBJECTIVE The purpose of this study is to assess the effects of applying Garcinia cambogia to cultured human nasal epithelial cells. MATERIALS AND METHODS A cell culture was set up consisting of human primary nasal epithelial cells harvested during septorhinoplasty from volunteers. The cells came from individuals with no history of rhinosinusitis. One assay for assessing cytotoxicity in cell culture utilizes MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide). This method allows visualization of fragmented DNA, condensation of nuclei and changes to the external cellular membrane or cytoskeleton. Our study employed this method. Nasal epithelial cells at 37°C were exposed in culture to G. cambogia for a period of 24 hours. Afterwards an MTT assay was used in conjunction with confocal microscopy to assess evidence of toxicity. The proliferative capability of the nasal epithelial cells was also evaluated by inducing a scratch injury to cultured cells followed by light microscopic examination. RESULTS Testing for cytotoxicity in this manner indicates that G. cambogia does not appear harmful to cultured nasal epithelial cells when applied directly. The cells exposed to this plant extract were still fully viable 24 hours afterwards. There was no increase in viability at the level of statistical significance. It was noted, however, that proliferation did increase slightly within the exposure period. The MTT assay and confocal microscopy confirm these findings. Under confocal microscopic examination, a compact morphology with unaltered nuclear and cytoskeletal appearances was observed. Thus, there is no evidence suggesting viability is impaired or that cytotoxicity occurs. Ordinary light microscopic examination showed the area denuded of cells had become re-covered completely within 24 hours in the cultures where G. cambogia had been applied. The result suggests that exposure to G. cambogia has no significant effect in terms of stimulating or inhibiting cellular proliferation. CONCLUSIONS G. cambogia may offer clinical benefit as a supplementary topical treatment for inflammation of the nose and sinuses, as seen in chronic and acute rhinosinusitis, or nasal polyps. The plant appears to increase nasal epitheliocytic proliferation slightly, as revealed by the MTT assay. There were no indications of a cytotoxic effect on epithelial cells of the nose.

Abstract
Rhinosinusitis is one of the most common diseases today. Among diseases requiring treatment with antibiotics, it is the fifth most common. Acute rhinosinusitis is a significant medical problem that can significantly lower quality of life and can cause a large economic impact on society. Herein, we collected and analyzed data from several published studies regarding sinusitis with the aim of creating a sinusitis model. We included data from 786 studies published between 1996 and 2016 that came up on Google, Pro Quest Central or PubMed using the following keywords (or combinations thereof): "sinusitis", "rhinosinusitis", "experimental", "animal", "model", "rat", "rabbit", "guinea pig" and "mice". An appropriate sinusitis model must be established using the correct animal. Thus far, sinusitis models have been published in rats, mice, and rabbits, with rabbits being the most frequently used animal. These animals are used because the anatomy and physiology of their sinuses are very similar to those of humans. While these animals can be used in surgical models, it must be noted that prolonged stress can cause them high mortality rates. Several studies have used strains of Streptococcus pneumoniae to induce rhinosinusitis; however, it has recently been shown that other pathogenic agents can be used for this purpose as well. In this review, we presented several experimental sinusitis models in rats, mice, and rabbits. We hope that by presenting these methods, researchers may be better able to design and perform more useful sinusitis studies.

Abstract
OBJECTIVE This study used the Sniffin' Sticks test battery to evaluate olfactory function in employees of a bakery exposed to flour dust. SUBJECTS AND METHODS The study enrolled 43 individuals with exposure (i.e., to flour) plus 41 healthy volunteers as controls. Olfactory function was assessed in these subjects through the use of the Sniffin' Sticks test battery. The overall score was calculated by adding up the scores for each of the 12 separate odors. A score of 6 or less was deemed anosmia, from 7 to 10 hyposmia, and a score of 11 or 12 was taken to indicate no impairment of olfaction. RESULTS There was a statistically significant difference between the scores obtained in the exposure group (10.09±2.29) and the control group (10.73±2.07), the exposure group having a lower score (p<0.05). Within the exposure group, men and women did not score differently (p>0.05). Furthermore, in this group, the overall score did not correlate significantly with age, sex, length of employment, or use of tobacco or alcohol use (p>0.05). Using the scheme employed in this study, 9.3% of the exposed workers were anosmic, compared to 9.8% in the controls, whereas 34.9% of baker workers were hyposmic, compared to just 14.6% of the controls. Thus, our study shows that impairment of the ability to smell was present in 44.2% of individuals exposed occupationally to flour dust. CONCLUSIONS This study reveals that being exposed to flour dust reduces the ability to smell normally. In order to minimize the impact of being exposed, workplaces should ensure adequate ventilation and provide workers with protective facemasks.

Abstract
OBJECTIVE We evaluated how efficacious indomethacin, at two different doses, is in the treatment of an experimental model of sinusitis in rats. MATERIALS AND METHODS Twenty-one Wistar albino rats (all male) were sorted at random into one of three groups: 1st group (n=7) was placebo. 2nd group (n=7). These rats had sinusitis induced experimentally, following indomethacin 3 mg/kg, 5 days was administered to them. 3rd group (n=7). These rats had sinusitis induced experimentally, following indomethacin 6 mg/kg, 5 days was administered to them. The animals' sinonasal mucosae were examined histopathologically by standard light microscopy. RESULTS Experimental sinusitis was observed in the 2nd and 3rd groups, but not in the rats administered a placebo. Although the inflammatory features of sinusitis were found to be significantly decreased in the animals administered indomethacin 3 mg/kg (the 2nd group), this anti-inflammatory effect was even greater in the 3rd group, where indomethacin 6 mg/kg had been administered. Indomethacin at either dose was superior to placebo in reducing inflammatory features of sinusitis. CONCLUSIONS Topical use of indomethacin nasal drops decreased the inflammatory features in experimentally induced acute sinusitis. Moreover, a higher dose of indomethacin (6 mg/kg) was more efficacious than a lower dose (3 mg/kg). The present study is valuable as an initial step in showing the need to undertake human trials to see the effect of indomethacin nasal drops on sinusitis in humans. In acute rhinosinusitis, the use of topical anti-inflammatory drops may help to decrease the symptoms and may be used adjunctively with antibiotic treatment.

Abstract
AIM To investigate changes in olfactory bulb (OB) volume in patients with idiopathic normal-pressure hydrocephalus (NPH). MATERIALS AND METHODS This multicentric retrospective study included a test group of 23 patients with NPH (10 male and 13 female patients) and a control group of 27 healthy participants without hydrocephalus. The OB volume in all participants had been measured using cranial magnetic resonance imaging (MRI). In the NPH group, positivity for disproportionately enlarged subarachnoid space hydrocephalus (DESH) was also evaluated. RESULTS The OB volumes of the NPH group (R 38.29 ± 9.34 mm3 and L37.52 ± 9.59 mm3) were significantly lower than those of the control group (R 45.87 ± 7.33 mm3 and L48.41 ± 7.62 mm3) bilaterally. There were no significant differences between right and left OB volumes in the NPH group. Nine of the 23 patients were DESH positive and 14 were DESH negative. There were no significant differences between OB volumes of the DESH positive and DESH vpatients in the NPH group. In both groups, there was a positive correlation between right and left OB volumes. There were no significant correlations between OB volumes and age or gender. In the NPH group, there were no significant correlations between DESH positivity and OB volumes. CONCLUSION OB volume decrease and olfactory problems should be taken into account in idiopathic NPH patients. When expanded ventricles and decreased OB volume are observed at cranial MRI, a diagnosis of idiopathic NPH should be considered.

Abstract
SUMMARY The lips are an essential component of the symmetry and aesthetics of the face. Cosmetic surgery to modify the lips has recently gained in popularity, but the results are in some cases disasterous. In this review, we describe the features of the ideal lips for an individual's face. The features of the ideal lips with respect to facial anatomy, important anatomical landmarks of the face, the facial proportions of the lips and ethnic and sexual differences are described. The projection and relative sizes of the upper and lower lips are as significant to lip aesthetics as the proportion of the lips to the rest of the facial structure. Robust, pouty lips are considered to be sexually attractive by both males and females. Horizontal thirds and the golden ratio describe the proportions that contribute to the beauty and attractiveness of the lips. In young Caucasians, the ideal ratio of the vertical height of the upper lip to that of the lower lip is 1:1.6. Blacks, genetically, have a greater lip volume. The shape and volume of a person's lips are of great importance in the perception of beauty by humans. The appearance of the lips in part determines the attractiveness of a person's face. In females, fuller lips in relation to facial width as well as greater vermilion height are considered to be attractive.

Abstract
OBJECTIVES To assess postoperative pain and pattern of recovery to normal diet in children who underwent tonsillectomy. METHODS Cold steel tonsillectomy (or adenotonsillectomy) was performed in 61 children. Haemostasis was attained with sutures in Group 1 (n = 30, 8 tonsillectomy and 22 adenotonsillectomy), and electrocautery in Group 2 (n = 31, 6 tonsillectomy and 25 adenotonsillectomy). Information obtained included postoperative pain scores and the number of postoperative days taken to resume normal diet. The pain score was evaluated with the Wong-Baker FACES® Pain Rating Scale (WBFS). RESULTS Pain values in Group 1 (haemostasis with sutures) were significantly lower than those in Group 2 (haemostasis with cauterisation) from the 6th hour to the 7th postoperative day (P < .05). For both liquid and solid food, Group 1 returned to normal diet earlier, compared to Group 2 (P < .05). When comparing patients undergoing tonsillectomy vs adenotonsillectomy, resumption of normal diet was achieved later in the adenotonsillectomy patients (P < .05). In terms of postoperative bleeding, there were 2 significant events in Group 2 (electrocautery group), occurring on the 1st (severe) and 10th day (slight) in 2 children (6.5%). There were no postoperative bleeding events in Group 1. CONCLUSION Our results showed that suture haemostatis causes less pain and faster resumption of normal diet compared to electrocautery. In view of this, we recommend the use of sutures for achieving intraoperative haemostasis in paediatric patients.

Abstract
This report has been prepared by the European Academy of Allergy and Clinical Immunology Task Force on Allergic Rhinitis (AR) comorbidities. The aim of this multidisciplinary European consensus document is to highlight the role of multimorbidities in the definition, classification, mechanisms, recommendations for diagnosis and treatment of AR, and to define the needs in this neglected area by a literature review. AR is a systemic allergic disease and is generally associated with numerous multi-morbid disorders, including asthma, eczema, food allergies, eosinophilic oesophagitis (EoE), conjunctivitis, chronic middle ear effusions, rhinosinusitis, adenoid hypertrophy, olfaction disorders, obstructive sleep apnea, disordered sleep and consequent behavioural and educational effects. This report provides up-to-date usable information to: (1) improve the knowledge and skills of allergists, so as to ultimately improve the overall quality of patient care; (2) to increase interest in this area; and (3) to present a unique contribution to the field of upper inflammatory disease.

Abstract
OBJECTIVE To investigate the potential preventive effect of resveratrol in rats exposed to acoustic trauma (AT). MATERIALS AND METHODS In this experimental study, Wistar albino rats were divided into three groups: Group 1 (Control, n = 6), Group 2 (AT, n = 6), and Group 3 (resveratrol + AT). The rats in Group 2 were exposed to AT. The rats in Group 3 received resveratrol (300 mg/kg/day) via gavage for 7 days. On day 7, the rats were exposed to AT 10 min following resveratrol treatment. Histological sections of the cochleae were examined using light microscopy, transmission (TEM), and scanning electron microscopy (SEM). RESULTS The cochlear hair cells, stereocilia, and Deiters' cells of the control group appeared normal in all microscopic evaluations. In Group 2, light microscopy revealed predominantly inner hair cell loss, although the outer hair cells were affected. TEM and SEM examination showed severe loss of stereocilia and SEM revealed stereocilia arranged in an asymmetric array. The cochlear structure in Group 3 appeared well preserved under the light microscope, and although TEM and SEM revealed stereocilia loss, the hair cells and stereocilia appeared near normal compared with those of Group 2. CONCLUSIONS Resveratrol may have a protective effect against AT damage in the cochlea, most likely through its antioxidant activity. Our results may be useful for studies in humans exposed to AT and noise-induced hearing loss related to chronic exposure to occupational noise.

Abstract
UNLABELLED Smell functions in patients with multiple sclerosis: a prospective case-control study. OBJECTIVES The aim of this study is to evaluate the smell function in patients with multiple sclerosis (MS). METHODS Twenty subjects (six males, 14 females) who were diagnosed as having MS, based on the 2010 Revised McDonald criteria, and 20 healthy individuals (six males, 14 females) were included in this study. In order to measure smell identification abilities, each subject completed the 12-item Brief Smell Identification Test (BSIT). Central and peripheral regions of smell were measured using cranial magnetic resonance (MR) images. The central regions of smell (the temporal lobe insular gyrus and the corpus amygdala) and the peripheral regions of smell (the olfactory bulb, tract and sulcus) were examined in the cranial MR images. Regions of smell were also evaluated for the presence of MS lesions (plaques). RESULTS The total BSIT scores of the subjects in the MS group were found to be significantly lower than those of the control group (p<0.05). In the MS group, measurement values of the central regions of smell (right corpus amygdala diameter, right and left corpus amygdala) were significantly higher than those of the control group (p<0.05). There were no MS 'lesions in the peripheral regions of smell, but MS lesions were observed in the central regions: the right temporal lobe insular gyrus (four patients, 20.0%); the left temporal lobe insular gyrus (two patients, 10.0%); and the right corpus amygdala (one patient, 5.0%). While these results are not sufficient for statistical analysis, the total smell scores of these patients were found to be low. CONCLUSION There is a deterioration in the smell functions of patients with MS. Therefore, we highly recommend that ENT specialists use the easily accessible and reliable BSIT for the diagnosis of smell disorders.

Abstract
OBJECTIVES To investigate the role of viral infection in benign paroxysmal positional vertigo (BPPV). METHODS In this retrospective study, 483 patients with BPPV were included in the study group. The control group consisted of 461 healthy subjects. In both groups, serologic analysis of viral agents (HSV1, HSV2, Herpes zoster, EBV, CMV, adenovirus, influenza, and parainfluenza virus) was performed. RESULTS With the exception of influenza and parainfluenza, all viral serology values were higher in the BBPV group than the control group. We also observed seasonal variation. The BPPV group exhibited elevated values for HSV1 and adenovirus in March and May, for Herpes zoster, adenovirus, and influenza in April, for HSV1 in June, and for HSV1 and CMV in September, compared to the control group. In October, the BPPV group showed increased values for all of the viruses studied, compared to the control group. CONCLUSION BPPV is associated with positive viral serology, particularly during certain months of the year, mainly in spring and autumn. Viral infection might promote BPPV attacks due to the development of vestibulopathy or induce secondary BPPV via viral infection-related neurolabyrinthitis.

Abstract
OBJECTIVES To compare the size of the nasal septal body (SB) and inferior turbinate (IT) of subjects grouped by sex and age. METHOD We measured SB and IT areas (in cm2) bilaterally in computed tomography (CT) sections of 150 para nasal sinuses from 72 males and 78 females. RESULTS The right and left SB areas were smaller in females than in males. In the s25-year-old group, the right IT (RIT) was significantly smaller in females than in males. In the 26-35 and 46-45 age groups, the right SB (RSB) was significantly smaller in females than in males. CONCLUSION The nasal SB may play a role in nasal physiology similar to a turbinate and help support optimal airflow. The vascular and glandular structures of the SB should be investigated in detail, and minimal invasive procedures should be performed in nasal surgery to avoid damaging essential structures.

Abstract
OBJECTIVE In this study, we aimed to review the National Newborn Hearing Screening (NNHS) programme data obtained from Corlu, located in west part of Turkey for the last 4 years. SUBJECTS AND METHODS A total 11575 newborns that were either born in Çorlu State Hospital or referred from other Health Care Centers, between September 2009 and November 2012 were included into the study. Automated-Transient Evoked Otoacoustic Emission (A-TEOAE) test and Automated-Auditory Brainstem Response (A-ABR) were used as screening tests. When the newborn had failed at the initial A-TEOAE test, then the test was repeated after 15 days. If the same result was obtained at the second test; the newborns were referred for ENT examination. A-TEOAE and A-ABR screening tests were performed as the third stage evaluation. The failed newborns were referred for clinical ABR test. RESULTS Out of 11575 newborns, 593 (5.12%) had failed the test and they were referred for clinical ABR. Out of these 593 neonates, 470 had passed the diagnostic ABR test at the referral center. Bilateral and unilateral sensori-neural hearing loss (SNHL) was detected at 15 and 7 babies respectively, 10 of 22 of these babies had risk factors such as family history of hearing loss, and parental consanguinity. CONCLUSIONS The final hearing impairment and risk factor rates of our study was similar with literature. Although referral rates and the number of default babies gradually decreased in the last 4 years; definitive diagnosis and hearing aid initiation times need to improvement.

Abstract
OBJECTIVE The pathogenesis of sinonasal polyps has not been known completely. We investigated the role of endothelial Nitric Oxide Synthase (eNOS) in the pathogenesis of sinonasal polyps. PATIENTS AND METHODS Study group (Groups 1-3) consisted of nasal polyp samples of patients with sinonasal polyps; and control group consisted of inferior turbinate samples of patients without nasal polyp. In Group 1: 14 specimens from ethmoid sinus; in Group 2: 10 specimens from nasal cavity; in Group 3: 10 specimens from maxillary sinus; and in Group 4 (Control): 9 specimens from inferior turbinate were included. By immunohistochemical staining technique, eNOS Positivity Index in mucosal layers; and in the inflammatory cells were assessed. RESULTS eNOS Positivity Index was higher at apical layer of epithelium; and perivascular and glandular parts of subepithelial layer. As a rate of mononuclear cells increased, eNOS positivity increased at basal part of epithelium. In eNOS Positivity Index of mononuclear cells increased ones, eNOS values also increased at glands of subepithelial layer. In nasal cavity, eNOS positivity index of all cells was significantly higher than that of the control group. Increased eNOS all cells positivity index values were seen with decreased glandular and endothelial eNOS values. In all cells group, fibroblasts were seen beside the mononuclear cells. It was observed that eNOS was not expressed in PMNC (mainly neutrophils), growing more in acute inflammatory process; and was expressed in MNCs and all cells group with fibroblasts which were the cells of chronic inflammatory process. Especially MNCs and fibroblasts may play a role in the polyp formation process. In males and in patients with longer polyp duration, eNOS values decreased. CONCLUSIONS We concluded that eNOS Positivity Index was higher at apical layer of epithelium; and perivascular and glandular parts of subepithelial layer. eNOS plays role in vascular dilatation, increases in vascular permeability; increases in nasal secretion due to glandular secretion; and edema in subepithelial and deep layers of the mucosa by affecting glands. Irritant agents in the breathing air and environment may cause increase in eNOS values at apical part of epithelium and may promote polyp formation by vasodilatation and increased glandular secretion due to increased nitric oxide values. In elderly patients and in long standing polyps, eNOS values decreased causing more fibrotic polyps.

Abstract
OBJECTIVES The aim of this study was to investigate the effects of N2O-O2 mixture (Inspired O2 30%) on middle ear pressure (MEP) in children compared with the effects of an air-oxygen mixture (Inspired O2 50%). METHOD The study included thirty child patients who underwent general anaesthesia for different reasons, with the exception of ENT problems and ear interventions. They were randomly divided into two groups. Group 1 (15 children: 10 male and 5 female) received a N2O-O2 mixture (Inspired O2 30%); and group 2 (15 children: 10 male and 5 female) were given an air-oxygen mixture (Inspired O2 50%). MEP was measured using a portable impedance analyser before the operation (PreO),10 minutes after intubation (10AEn), 30 minutes after intubation (30AEn), 10 minutes before extubation (10BEx), 15 minutes after the operation (PO15), 30 minutes after the operation (PO30), 1 hour after the operation (PO1h) and 6 hours after the operation (PO6h). RESULTS The pressure and compliance values were the same in groups 1 and 2. The pressure-time graphs for the two groups were different: in Group 2, MEP rose quickly at 10AEn and positive pressure values were seen in the middle ear. MEP then fell rapidly until the end of the surgery and lower and negative pressures (Mean -50 daPa) were observed at PO6h. In Group 1, MEP was elevated at 10AEn and positive pressure was found (but not as high as in Group 2). MEP then fell more slowly. In other words, positive pressure in the middle ear persisted longer and the middle ear was subjected to positive pressure and nitrogen over a longer period. Separate analyses were made in Groups 1 and 2 of pressure differences and of compliance values at eight measurement points using the Friedman test. Differences in pressure values were found to be statistically significant in both Group 1 (p = 0.000) and Group 2 (p = 0.000). In Group 1, all the 10AEn and 30AEn values were significantly higher than the PreO, PO30, PO1h and PO6h values. The 10BEx value was significantly higher than the PreO and PO1h values. The PO15 value was significantly higher than the PreO value. In Group 2, the PO6h value was significantly lower than the 10BEx, 10AEn and 30AEn values. The PO1h value was significantly lower than the 30AEn values. The MEP values increased in Group 1 in younger and taller children and in children receiving anaesthesia for shorter periods. MEP values increased in Group 2 in younger and taller children, and in heavier children. MEP values fell with the length of anaesthesia. CONCLUSION In brief anaesthesia, nitrogen was not removed from the middle ear quickly in Group 1: middle ear pressure values were higher. The nitrous oxide remained in the middle ear longer and so the possibility of ear toxicity may increase. In Group 2, 50% O2 was rapidly absorbed and removed from the middle ear and so middle ear pressure was not as high. It may be concluded that air-oxygen mixture (Inspired O2 50%) anaesthesia should be recommended as being more reliable in tympanoplasties and other middle ear interventions than a N2O-O2 mixture (Inspired O2 30%).

Abstract
OBJECTIVES We investigated the role of inducible nitric oxide synthase (iNOS) in the pathogenesis of sinonasal polyps. METHODS Adult patients (21 men, 3 women) with nasal polyposis underwent functional endoscopic sinus surgery. Nine adults without polyps (6 men) who underwent septoplasty and/or rhinoplasty served as controls. Polyp specimens came from three regions: the maxillary sinus (10), ethmoid sinus (14), and nasal cavity (10). Control group samples (9) came from the inferior turbinate. Specimens were evaluated in eight mucosal layers for count and distribution of inflammatory cells and iNOS expression. An iNOS positivity index (PI) was determined for the epithelium (E), subepithelial layer of the lamina propria (SE), and deep paraglandular layer of the mucosa (D). RESULTS Polymorphonuclear cell (PMNC) % values of the ethmoid and maxillary sinus and overall ethmoid sinus PI were significantly higher in the polyp group. Patients with longer polyp duration, D-perivascular (D-pv), and a higher Brinkmann index had decreased ethmoid sinus D PIs. However, in older patients and patients with longer polyp duration, perivascular PIs increased in maxillary sinus SE and D, respectively. Furthermore, as PMNC % and iNOS-PMNC PI increased, SE_glandular and epithelial_apical iNOS values decreased. In the ethmoid and maxillary sinuses, iNOS_D_. endothelial values increased but decreased in the nasal cavity. CONCLUSIONS iNOS may play a role in sinonasal polyp pathogenesis, especially in mucosal SE and D layers. Increased vascular permeability, stromal edema, inflammatory cell migration into the stroma of the mucosa, and increased mucosal gland secretion may result in polyp formation.

Abstract
OBJECTIVES Language delays are common in childhood, may be associated with delays in other areas of development, and can affect school performance. Various tests designed for general developmental screening or specifically for language are used to assess developmental status in preschool children. Knowledge of the probabilities of normal developmental milestones may simplify detection of problems and delays. The aim of this study was to determine the milestones of language development in Turkish children. PATIENTS AND METHODS We assessed data from application of the Denver II Developmental Screening Test's Turkish standardization to 1,993 children, 976 (49.0%) boys and 1,017 (51.0%) girls aged 0.6-82.0 months. We used binary logistic regression to analyze the predicted probability of accomplishing the language items on the Denver II Developmental Screening Test. RESULTS We determined the sequence of assessed language items and the ages associated with accomplishing those items, as well as the ages at which 25, 50, 75, and 100% of children passed the items. Language items followed a sequential route. Graphs had polynomial slopes. CONCLUSION Curves for normal development allow detection of aberrations in the predicted course of language development, and may facilitate earlier diagnosis of delays in language.

Abstract
OBJECTIVES We investigated the effects of subjective tinnitus on sleep quality and Mini Mental Status Examination (MMSE) scores of participants. METHODS The study group consisted of 15 patients, including 21 ears with tinnitus (6 bilateral, 9 unilateral). The control group consisted of 8 healthy patients with normal hearing and no tinnitus (16 ears). We assessed sleep quality using the Mini Sleep Questionnaire (MSQ) and mental health using the MMSE. RESULTS Sleep delay (SD) was significantly higher in tinnitus patients (5.28 +/- 2.23) compared to controls (3.25 +/- 2.56) (p = 0.018). Subjective tinnitus loudness level (STLL) scores were higher and sleep quality was impaired in females, older patients, and patients with lower MMSE scores. Sleep quality was also worse in patients with longer tinnitus duration. In younger and well educated patients, MMSE scores were higher. Higher STLL scores and shorter tinnitus duration were associated with lower MMSE scores. Patients with newly developed tinnitus reported more disturbances and showed greater effects on mental and cognitive functioning. CONCLUSION In subjective tinnitus patients, sleep delay values increased. Long tinnitus duration and high STLL scores may affects patients' cognitive functions as shown by decreased MMSE scores. Furthermore, mental status changes in tinnitus patients were frequently overlooked.
