Abstract
OBJECTIVE Most patients with olfactory dysfunction experience stress and anxiety because of the inconvenience and changes caused by the loss of olfaction. However, psychological assessment is not performed routinely in patients with olfactory dysfunction, and the characteristics of these patients with psychological depression are unclear. METHODS In this study, we used the Self-rating Depression Scale to evaluate the degree of depression in patients who visited our clinic with olfactory dysfunction and examine the characteristics of these patients with strong depressive tendencies. Patients who visited our clinic between April 2019 and March 2020 with complaints of olfactory dysfunction were included in the study. RESULTS A total of 180 patients (79 male and 101 female) underwent olfactory examination and completed the Self-rating Depression Scale. Eighty-six and 94 patients were included in the low depression and high depression groups, respectively. Binomial logistic regression analysis showed significant positive associations of Self-rating Depression Scale scores with female sex and the presence of parosmia/phantosmia (p < 0.05). CONCLUSION In our study, approximately half of the patients with olfactory dysfunction had depressive tendencies especially in female and parosmia/phantosmia patients. We believe that psychological assessments, such as that with the SDS, can help identify patients with olfactory dysfunction who may be at a greater risk of developing depression.

Abstract
INTRODUCTION Zinc deficiency may worsen the severity of olfactory dysfunction; however, the relationship between serum zinc levels and therapeutic effects on olfactory dysfunction remains uncertain. This study investigated the relationship between normalising serum zinc levels and the therapeutic effects on olfactory dysfunction. METHODS Forty-two patients diagnosed with post-infectious, posttraumatic, and idiopathic olfactory dysfunction, with serum zinc levels < 70 µg/dL, were included in the study. All patients were treated with mecobalamin, tokishakuyakusan, and polaprezinc. The patients were divided into 2 groups: the zinc-normalised (≥ 70 µg/dL) and zinc-deficient (< 70 µg/dL) groups, based on their post-treatment serum zinc levels. Olfactory test results were compared in each of the 2 groups. RESULTS The patients were treated for a median of 133 days. The zinc-normalised group had significantly better results in all olfactory tests (detection/recognition thresholds of the T&T olfactometer, odour identification test (Open Essence), visual analogue scale for olfactory dysfunction, self-administered odour questionnaire). In contrast, only the self-administered odour questionnaire showed a significant improvement in the zinc-deficient group, with no significant differences observed in the other olfactory tests. When comparing the changes in the olfactory test scores between the 2 groups, significant differences were observed in the detection/recognition thresholds of the T&T and Open Essence results. CONCLUSION These findings suggest that patients with olfactory dysfunction may have difficulty improving their olfactory function if they also have zinc deficiency. Furthermore, normalisation of zinc deficiency may contribute to the improvement of olfactory dysfunction with general treatment.

Abstract
BACKGROUND Rhinoplasty is one of the most popular plastic surgery techniques. The evaluation of both functional and cosmetic aspects of rhinoplasty is essential for planning and assessing surgery results. The Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) is a validated questionnaire used to assess both functional and aesthetic symptoms in patients with nasal problems, and it has been translated into several languages. The purpose of this study was to translate, culturally adapt, and validate the SCHNOS in Japanese among patients undergoing rhinoplasty. METHODS This was a prospective validation study of the Japanese version of the SCHNOS (J-SCHNOS). The first phase involved translation and cross-cultural adaptation of the SCHNOS. The second phase included validation of the J-SCHNOS among native Japanese speakers. RESULTS In total, 357 participants completed the final version of the J-SCHNOS (219 males and 138 females; mean age 43.4 years). The J-SCHNOS showed high internal consistency with excellent Cronbach's alpha values for both obstruction (SCHNOS-O) (0.96) and cosmetic (SCHNOS-C) (0.93) domains. The reproducibility was high, with an excellent intraclass correlation coefficient (ICC) >0.9 for all items. Exploratory factor analysis showed unidimensional structures in both the SCHNOS-O and the SCHNOS-C. CONCLUSION The J-SCHNOS is a reliable and valid tool to assess the severity of nasal problems in patients undergoing rhinoplasty.

Abstract
BACKGROUND We investigated the outcomes of postoperative radiation therapy for olfactory neuroblastoma (ONB) and our cross-departmental collaboration to enhance the effectiveness of cancer treatment. METHODS We retrospectively evaluated 22 patients with ONB who underwent postoperative radiotherapy after tumor resection. En bloc resection was performed; pathology specimens were prepared in coronal sections; and irradiation fields were determined after discussion with radiation oncologists, head and neck surgeons, and pathologists. RESULTS The overall survival and local control rates were 95.5% and 100%, respectively, at a median 37-month follow-up. The 3- and 5-year disease-free survival (DFS) rates were 64.4% and 56.3%, respectively. Of the 22 patients, 9 (8 Kadish C and 1 Kadish B) had disease recurrence. Of the nine patients, five had positive margins and two had closed margins; cervical lymph node recurrence occurred in six, and distant metastasis with or without cervical lymph node recurrence occurred in three. DFS analysis of risk factors showed no statistically significant differences, but positive margins were a significant recurrence factor in multivariate analysis. CONCLUSIONS The local control rate of ONB treated with postoperative radiation therapy was 100%. This may be attributed to cross-departmental cooperation between head and neck surgeons, pathologists, and radiation oncologists, which resulted in accurate matching of CT images for treatment planning with the location of the tumor and positive margins. Longer follow-up periods are required to evaluate the effectiveness of our strategy.

Abstract
Introduction The treatment of nasal septum perforation solely by surgical intervention presents significant challenges. This study evaluated the effect of basic fibroblast growth factor (bFGF) in combination with collagen/gelatin on wound healing of nasal septum perforation in a rabbit animal model. Methods A nasal septum perforation rabbit model was created. bFGF was added to a collagen/gelatin fixture and placed adjacent to the perforation, which is a complete defect. The rabbits were divided into three groups: the sham group that underwent the surgical procedure only, bFGF (-) group that received collagen/gelatin fixture without bFGF, and bFGF(+) group that received collagen/gelatin fixture with bFGF. The dimensions of the perforations were measured after 4 weeks, and the septum was subjected to histological examination. Results All perforations remained open in the sham group (closure rate: 20.4%-83.1%). The closure rates of the bFGF(-) and bFGF(+) groups were 49.4%-68.8% and 72.7%-100%, respectively. No significant difference was noted in the closure rates between the sham and bFGF(-) groups; however, significant differences were observed between the sham and bFGF(+) groups, and the bFGF(-) and bFGF(+) groups (p < 0.05), indicating that bFGF promoted perforation closure. Conclusions The study demonstrated that bFGF with collagen/gelatin carrier promoted wound healing in a rabbit model of nasal septum perforation.

Abstract
BACKGROUND Sinonasal neoplasms, whether benign and malignant, pose a significant challenge to clinicians and represent a model area for multidisciplinary collaboration in order to optimize patient care. The International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors (ICSNT) aims to summarize the best available evidence and presents 48 thematic and histopathology-based topics spanning the field. METHODS In accordance with prior International Consensus Statement on Allergy and Rhinology documents, ICSNT assigned each topic as an Evidence-Based Review with Recommendations, Evidence-Based Review, and Literature Review based on the level of evidence. An international group of multidisciplinary author teams were assembled for the topic reviews using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses format, and completed sections underwent a thorough and iterative consensus-building process. The final document underwent rigorous synthesis and review prior to publication. RESULTS The ICSNT document consists of four major sections: general principles, benign neoplasms and lesions, malignant neoplasms, and quality of life and surveillance. It covers 48 conceptual and/or histopathology-based topics relevant to sinonasal neoplasms and masses. Topics with a high level of evidence provided specific recommendations, while other areas summarized the current state of evidence. A final section highlights research opportunities and future directions, contributing to advancing knowledge and community intervention. CONCLUSION As an embodiment of the multidisciplinary and collaborative model of care in sinonasal neoplasms and masses, ICSNT was designed as a comprehensive, international, and multidisciplinary collaborative endeavor. Its primary objective is to summarize the existing evidence in the field of sinonasal neoplasms and masses.

Abstract
A critical procedure in the transcribriform approach is the resection of the crista galli. However, the standard technique for crista galli resection has several disadvantages. We reviewed the cases of patients with olfactory neuroblastomas who underwent an endoscopic endonasal transcribriform approach using a newly developed technique for crista galli resection. We performed a cadaveric study to measure the superior accessibility limits using the proposed method. We included 38 patients with olfactory neuroblastomas in this study. The tumor invaded the posterior crista galli in four patients. The anterior end of the crista galli was not invaded by the tumor. Our cadaveric study showed that the dura was approachable to the point that was 7.4 ± 1.3 mm superior and 23.2 ± 7.2 mm lateral to the foramen cecum following crista galli removal. By resecting the crista galli in advance, manipulation of the superior dura became feasible.

Abstract
OBJECTIVE The histological findings of wound healing depending on different nasal packing materials and replacement periods were lacking. METHODS Mucosal defects were created in the nasal septum of rabbits and covered with Spongel®, Algoderm®, or Nasopore®, which were cleaned on Day 14. To investigate the effect of replacement durations, Spongel® was removed on Days 3 and 7. All nasal septal specimens were collected on Day 28. Samples without packing material were prepared as controls. Depending on residual packing materials in the regenerated tissue, specimens were classified into the remnant and non-remnant groups, and morphology was compared using epithelium grade score and subepithelial thickness. RESULTS The epithelium grade score in the Spongel-14d group was lower than that in the other groups (p < 0.05). Subepithelial thickness was higher in the Algoderm-14d and Spongel-14d groups (p < 0.05). Epithelium grade scores were higher and subepithelial thicknesses were lower in the Spongel-3d and -7d groups than in the Spongel-14d group. Epithelium grade score was lower and subepithelial thickness was higher in the remnant group (n = 10) than in the non-remnant group (n = 15; p < 0.05). CONCLUSIONS Differences in packing materials and placement durations affected wound healing of nasal mucosa. The selection of appropriate packing materials and replacement duration was considered essential for ideal wound healing. LEVEL OF EVIDENCE NA Laryngoscope, 134:562-568, 2024.

Abstract
Dupilumab inhibits interleukin-4Rα and suppresses type 2 inflammation. Careful administration of dupilumab is required because it increases the blood eosinophil count secondary to a decrease in local eosinophil counts, sometimes resulting in eosinophilic complications. We herein report a case of recurrent chronic eosinophilic pneumonia after switching from benralizumab to dupilumab. A 54-year-old man with a history of eosinophilic pneumonia presented to our hospital with symptoms of cough, fever, and phlegm production six months after beginning dupilumab administration for recurrent chronic rhinosinusitis. When using dupilumab, it is essential to carefully monitor patients' eosinophil trends and pulmonary symptoms.

Abstract
OBJECTIVE Juvenile nasopharyngeal angiofibroma (JNA) is a very rare hemorrhagic vascular tumor that predominantly affects adolescent boys. The tumor is relatively large when detected, and the risk of intraoperative bleeding is high. We aimed to examine factors associated with intraoperative blood loss in JNA surgery. METHODS Thirteen patients with JNA who underwent surgery at the Jikei University Hospital between 2009 and 2020 were retrospectively reviewed, and factors associated with blood loss were examined by single regression analysis. RESULTS The mean age was 20.8 ± 7.7 years. Preoperative angiographic images were evaluated in 9 of the 13 cases. The 6 patients with the largest bleeding volumes, all had residual nutrient vessels from the internal carotid artery (ICA), with an average number of 2.5 vessels. The mean blood loss of patients with residual nutrient vessels from the ICA was 3037 ± 2568 mL. Single regression analysis of bleeding volume against the number of remaining nutrient vessels from the ICA and the total peak contrast density of nutrient vessels (Cmax) standardized by region of interest showed that the coefficient was positive (P < 0.05 for both), confirming a significant correlation between the 2, respectively. CONCLUSIONS The amount of bleeding significantly correlated with the number of remaining nutrient vessels from the ICA after preoperative embolization and with the total Cmax/region of interest. The ability to predict the amount of preoperative blood loss using this study will facilitate proposals for external incisions in patients with JNA.

Abstract
OBJECTIVES Eosinophilic chronic rhinosinusitis (ECRS) is known to recur after surgery. The treatment choice for recurrent ECRS, such as oral steroids or biological agents, must be chosen carefully, and identifying the lesion location may be useful. This study aimed to evaluate the postoperative course of ECRS patients and assess the relationship between endoscopic lesion location and postoperative oral steroid use. METHODS Patients with chronic rhinosinusitis who underwent bilateral endoscopic sinus surgery from April 2018 to March 2020 were divided into two groups based on the presence or absence of oral steroid use after surgery. The primary endpoint was the lesion location on endoscopic findings during surgery: middle turbinate, middle meatus, superior turbinate, superior meatus, nasal septum, and sphenoethmoidal recess. Subjective symptoms, blood tests, and computerized tomography (CT) findings (Lund-Mackay score) were evaluated as secondary endpoints. RESULTS Among 264 patients, 88 were diagnosed histologically with ECRS (mean 48.98 ± 1.40 years, 67 males/21 females). Twenty-three patients were steroid-using, 65 were steroid-free, and six stopped attending their appointments. Patients with sphenoethmoidal recess lesions were significantly more likely to require steroids (p = 0.019). There was a significant association between steroid use and younger age (p = 0.041), olfactory dysfunction (p = 0.021), and all sinuses (Frontal sinus: p < 0.001, Anterior ethmoid sinus: p = 0.002, Posterior ethmoid sinus: p = 0.011, Maxillary sinus: p = 0.018, Sphenoid sinus: p = 0.034, Total score: p < 0.001). CONCLUSION A sphenoethmoidal recess lesion was a risk factor for requiring postoperative steroids. Young age, olfactory dysfunction, and preoperative severe CT findings were also significant risk factors. LEVEL OF EVIDENCE 3 Laryngoscope, 133:2511-2516, 2023.

Abstract
OBJECTIVES Resonance properties of the nasal and sinus cavities are involved in the individuality of speech. However, detailed information on how alterations in the nasal cavity morphology affect voice quality is lacking. The aim of the present study was to investigate the effects of structural changes in the nasal cavity on voice production by spraying a topical adrenaline solution with a vasoconstrictive effect into the nasal cavity, causing nasal mucosal contraction. STUDY DESIGN Prospective. METHODS Overall, 51 adult volunteers were recruited from the Otorhinolaryngology Outpatient Department of the Jikei University Hospital from June to September 2022. Among them, 20 completed acoustic rhinometry and voice recordings before and after adrenaline spraying. The nasal consonant [N] uttered with the mouth completely closed was recorded for 5 seconds. The remaining 31 volunteers completed all auditory experiments. This was conducted to determine whether the changes in voice before and after adrenaline spraying could be discriminated against by the participants. RESULTS The nasal volume had increased 5 and 10 minutes after spraying compared to that before spraying, reaching a significance at 10 minutes (P = 0.06). It had increased at 2 and 5 cm from the external nostrils compared to that within 3 cm of the external nostrils (P = 0.04). Among the 31 volunteers in the auditory experiments, 30 had a discrimination rate >90%, with a mean of 96.3% (standard error, 3.2). The spectral envelope of the 16 frequency bands varied significantly at 500-Hz increments (P = 0.0006). In particular, changes in the high-frequency bands were larger between 4500 and 6000 Hz. CONCLUSIONS Nasal enlargement with 0.02% topical adrenaline affects the spectral envelope, particularly in the high-frequency bands between 4500 and 6000 Hz, and perceptibly alters the voice.

Abstract
Sinonasal inverted papilloma (IP) is at risk of recurrence and malignancy, and early diagnosis using nasal endoscopy is essential. We thus developed a diagnostic system using artificial intelligence (AI) to identify nasal sinus papilloma. Endoscopic surgery videos of 53 patients undergoing endoscopic sinus surgery were edited to train and evaluate deep neural network models and then a diagnostic system was developed. The correct diagnosis rate based on visual examination by otolaryngologists was also evaluated using the same videos and compared with that of the AI diagnostic system patients. Main outcomes evaluated included the percentage of correct diagnoses compared to AI diagnosis and the correct diagnosis rate for otolaryngologists based on years of practice experience. The diagnostic system had an area under the curve of 0.874, accuracy of 0.843, false positive rate of 0.124, and false negative rate of 0.191. The average correct diagnosis rate among otolaryngologists was 69.4%, indicating that the AI was highly accurate. Evidently, although the number of cases was small, a highly accurate diagnostic system was created. Future studies with larger samples to improve the accuracy of the system and expand the range of diseases that can be detected for more clinical applications are warranted.

Abstract
BACKGROUND There are multiple treatment methods for odontogenic sinusitis (OS); however, the optimal treatment remains unclear. AIMS/OBJECTIVE To determine the cure rate of OS after tooth extraction and the factors contributing to the cure. MATERIAL AND METHODS We prospectively identified 37 patients diagnosed with OS with an indication for causative tooth extraction. Before and three months after tooth extraction, the patients were assessed using sinus computed tomography and classified as either cured or uncured based on the absence or presence of soft tissue shadow in the maxillary sinus. The prognostic factors were analysed by comparing the two groups. RESULTS There were ten patients for whom all data could be obtained. The mean age of the patients at the time of tooth extraction was 53.8 ± 12.9 years (range, 34-75 years). In seven patients, the soft tissue shadow in the maxillary sinus disappeared; these patients were classified as cured. Uncured patients were significantly younger than cured patients (59.9 vs. 39.7 years). CONCLUSIONS AND SIGNIFICANCE Tooth extraction effectively treated OS in 70% of patients. However, even after tooth extraction, OS may not improve, particularly in younger patients.

Abstract
In traditional open maxillectomy, identifying the posterior margin is difficult because of its deep location and bleeding from the pterygoid venous plexus. Here, we present our endoscope-assisted total en bloc maxillectomy technique and discuss its merits and demerits compared to previously reported methods. We developed an endoscope-assisted total en bloc maxillectomy procedure. We reviewed a series of total maxillectomies performed with and without endoscopic assistance to verify the advantages of endoscopic assistance over conventional total maxillectomy. We analyzed (1) the precision using the distance of the remaining pterygoid process, (2) the operation time, and (3) blood loss. The length of the remnant pterygoid process was significantly shorter in the endoscopic assistance group. The operation time and blood loss were not significantly different between the two groups. Endoscopic assistance makes total maxillectomy more precise without requiring additional time and is a reasonable option for total maxillectomies.

Abstract
Background Extranodal NK/T-cell lymphoma, nasal type (ENKL), is an aggressive tumour with poor prognosis. Its early diagnosis may improve the prognosis of patients; however, it is often overlooked in many cases and misdiagnosed as an inflammatory sinus disease during its initial stage. Identifying the clinical characteristics of ENKL may aid otorhinolaryngologists in indicating cases early for a pathologic examination. In this study, we aimed to investigate the clinical characteristics of ENKL compared with that of diffuse large B-cell lymphoma (DLBCL), which is the most common nasal malignant lymphoma. Methods The backgrounds, clinical symptoms, blood test results, and computed tomography images of patients with nasal/paranasal malignant lymphoma in our hospital between 2012 and 2017 were investigated. The characteristics of ENKL and nasal DLBCL were compared to differentiate them. Results A total of 27 patients with nasal cavity and/or paranasal sinus lymphoma were included. Extranodal NK/T-cell lymphoma, nasal type, was diagnosed in 10 patients, while DLBCL was diagnosed in 17 patients. The median age of patients with ENKL was significantly lower than that of patients with DLBCL. All patients with ENKL had a unilateral lesion in the nasal cavity, with most located at the inferior turbinate. They also experienced nasal symptoms with significantly higher incidence of nasal obstruction and tendency of bleeding. Conclusion ENKL was often unilateral and caused nasal obstruction, unlike DLBCL. Those who are younger in age and have sinonasal tumour with unilateral nasal obstruction and bleeding should be considered for early and repeated biopsies at multiple sites, with ENKL taken into consideration.

Abstract
PURPOSE Endoscopic sinus surgery (ESS) is widely used to treat chronic sinusitis. However, it involves the use of surgical instruments in a narrow surgical field in close proximity to vital organs, such as the brain and eyes. Thus, an advanced level of surgical skill is expected of surgeons performing this surgery. In a previous study, endoscopic images and surgical navigation information were used to develop an automatic situation recognition method in ESS. In this study, we aimed to develop a more accurate automatic surgical situation recognition method for ESS by improving the method proposed in our previous study and adding post-processing to remove incorrect recognition. METHOD We examined the training model parameters and the number of long short-term memory (LSTM) units, modified the input data augmentation method, and added post-processing. We also evaluated the modified method using clinical data. RESULT The proposed improvements improved the overall scene recognition accuracy compared with the previous study. However, phase recognition did not exhibit significant improvement. In addition, the application of the one-dimensional median filter significantly reduced short-time false recognition compared with the time series results. Furthermore, post-processing was required to set constraints on the transition of the scene to further improve recognition accuracy. CONCLUSION We suggested that the scene recognition could be improved by considering the model parameter, adding the one-dimensional filter and post-processing. However, the scene recognition accuracy remained unsatisfactory. Thus, a more accurate scene recognition and appropriate post-processing method is required.

Abstract
Background: Empty nose syndrome (ENS) is caused by nasal turbinate surgery. The standard treatment for ENS is an inferior meatus augmentation procedure (IMAP) in which autologous tissue such as auricular cartilage, rib cartilage, or artificial material is transplanted into the nasal cavity. However, some challenges like a very small auricular cartilage are associated with these autologous tissue types. Moreover, since using rib cartilage is a highly invasive technique, the scar on the chest from where the harvesting is done is easily visible, and the artificial material is susceptible to infection. We used autologous dermal fat (ADF) in IMAPs in our study for the following reasons: the quantity of ADF could be increased or reduced as needed, ADF is considered a safer option than rib cartilage because it is harvested from superficial tissue, it is superior in terms of cosmetic appearance to harvested rib cartilage, and it has a lower risk of infection than any artificial material.Objective: The purpose of our study was to investigate the efficacy and safety of IMAPs using ADF.Methods: We included nine patients with ENS who underwent an IMAP using ADF. The patients' backgrounds and responses to the Empty Nose Syndrome 6-Item Questionnaire (ENS6Q) were recorded. Changes in each item of the ENS6Q before and after surgery (up to 3 months) were analyzed.Results: The postoperative ENS6Q total score and parameters were significantly better than their preoperative counterparts. Nasal dryness improved slightly less than other symptoms. There were no complications.Conclusions: The IMAP using ADF was effective in improving ENS symptoms; however, some physiological functions were difficult to improve, and dryness persisted. Autologous dermal fat is larger than auricular cartilage, less invasive than rib cartilage, and has a lower risk of infection than artificial material.

Abstract
The olfactory nerve map describes the topographical neural connections between the olfactory epithelium in the nasal cavity and the olfactory bulb. Previous studies have constructed the olfactory nerve maps of rodents using histological analyses or transgenic animal models to investigate olfactory nerve pathways. However, the human olfactory nerve map remains unknown. Here, we demonstrate that high-field magnetic resonance imaging and diffusion tensor tractography can be used to visualize olfactory sensory neurons while maintaining their three-dimensional structures. This technique allowed us to evaluate the olfactory sensory neuron projections from the nasal cavities to the olfactory bulbs and visualize the olfactory nerve maps of humans, marmosets and mice. The olfactory nerve maps revealed that the dorsal-ventral and medial-lateral axes were preserved between the olfactory epithelium and olfactory bulb in all three species. Further development of this technique might allow it to be used clinically to facilitate the diagnosis of olfactory dysfunction. Combined high-field MRI and DTI analyses in post-mortem mouse, marmoset, and human samples provide insight into the neural connections between nasal cavities and olfactory bulbs.

Abstract
OBJECTIVE Caudal septal deviation (CSD) correction during septorhinoplasty is challenging, and various surgical modifications and evaluations remain controversial. This study aimed to introduce an objective evaluation method based on computed tomography (CT) images to measure the effectiveness of septorhinoplasty for CSD treatment. METHODS We retrospectively analyzed preoperative and postoperative CT images of patients who had undergone functional open septorhinoplasty by the plastic surgery and otorhinolaryngology teams between January and September 2019. Using OsiriX Lite (Pixmeo, Switzerland), CSD was calculated as the distance between the septum midline and palatal plane. Deformation was categorized as C-shaped unilateral or S-shaped bilateral deviations. The change in the distance between preoperative and postoperative images was considered because of surgical intervention. RESULTS Twenty patients (mean age, 35 years; 13 males [65%], 7 females [35%]) were included. The median deviation was 3.01 mm (range, 0.45-7.34 mm) preoperatively and 1.6 mm (range, 0.5-2.86 mm) postoperatively, indicating a reduction of 1.26 mm (median, P < 0.05) due to surgical intervention. C- and S-shaped deviations were seen preoperatively in 9 (45%) and 11 (55%) patients and postoperatively in 6 (30%) and 14 (70%) patients, respectively. The mean ± SD time of analysis was 7 ± 2.1 minutes. CONCLUSIONS Caudal septal deviation showed significant changes from preoperative to postoperative CT images, based on the distance between the actual septum midline and the constructed straight septum. This allowed effective evaluation of surgical efficacy for septum straightening. Although additional studies are needed, this method allows clearer stratification of surgical outcomes.

Abstract
AIMS Endoscopic modified transseptal bi-nostril approach minimizes turbinate and olfactory mucosal invasion and ensures preservation of the turbinates and bilateral olfaction. The main objective of this study was to investigate the pre- and postoperative variations in olfactory function in patients using this approach, and the secondary objective was to investigate the complications associated with the surgical procedure. MATERIAL AND METHODS This study is a single-center prospective cohort study using STROBE analysis. To completely protect the bilateral turbinates and olfactory epithelium, this procedure provided access to the sphenoid sinus by a transseptal approach via the left nasal cavity and by the olfactory cleft approach via the right nasal cavity without any turbinate resection. A T&T olfactometer was used to assess the mean recognition threshold of the left, right, and bilateral nasal passages before and after surgery, and complications associated with the surgical approach were investigated. OBJECTIVES We included 27 patients who underwent endoscopic modified transseptal pituitary surgery with an olfactory and turbinate preservation approach at our hospital between April 2018 and December 2019. RESULTS The mean postoperative recognition threshold of the right, left, and bilateral nasal cavities did not worsen (P<0.001 for all) relative to the preoperative values, and there was no difference in values between the right and left nasal cavities (P=0.85). The nasal turbinates were preserved in all patients during the study period, and no recurrence was observed. CONCLUSION Our modified EETSA could be implemented as an approach for turbinate and olfaction preservation.

Abstract
BACKGROUND Advances in technique and instrumentation have improved outcomes after resection of anterior skull base tumors. However, cerebrospinal fluid (CSF) leak occurs in 4%-20% of patients. To reduce the risk of CSF leak, we have developed a novel reconstruction technique that consists of a 4-layered graft with patchwork suturing and hard material. OBJECTIVE To evaluate the effectiveness of this reconstruction technique when used for resection of anterior skull base tumors. METHODS This case series included 59 patients with anterior skull base tumors in whom the 4-layered closure technique was used. The main outcome measures were complications, including CSF leak, meningitis, postoperative bleeding, and infection. RESULTS There were no CSF leak cases or serious complications after closure of the anterior skull base using the 4-layered technique. CONCLUSION Closure of the anterior skull base in 4 layers prevented CSF leak and was not associated with any serious complications. However, further studies in larger numbers of patients are needed to confirm our outcomes using this closure method.

Abstract
BACKGROUND Olfaction plays an important role in our daily and social lives, both as adults and as children. This study assessed whether the ability to identify odours increases with age, as well as the ability in various age groups and the factors involved. METHODS The survey was performed in 2017 on 697 Japanese children (366 girls and 331 boys) aged 6-18 years who lived in Tsunan, Niigata Prefecture, Japan by using the 'Open Essence', a card-type odour identification test. We collected information regarding age, sex, and physical characteristic. We also inquired whether participants had siblings or if members of the family smoked, and whether they had conversations about odour at home. Statistical analysis was performed to evaluate the factors affecting odour identification abilities. RESULTS The results showed that the odour identification abilities of children increase with age, and children who have daily conversations about odours at home have better odour identification abilities. CONCLUSIONS Odour identification ability increases with age. In addition, our findings suggest that conversation may positively affect odour identification. Hence, it is important for children to be exposed to an environment where they develop an interest in smells for better growth of their olfactory identification ability.

Abstract
Although the number of postoperative maxillary cyst (POMC) cases has declined recently, a few reports of refractory cases have also been reported. The indications for endoscopic sinus surgery (ESS) for POMC removal are broadening and attempts to prevent postoperative recurrence at the cyst opening site have been widely investigated. Here, we have advocated our original pedunculated mucoperiosteal flap (CLAP flap; covered lateral and posterior wall flap of the maxillary sinus), where the bony area exposed intraoperatively is covered, to prevent postoperative recurrence. We have also presented the method for creating the CLAP flap. We classified the POMC as being medial, lateral, or anterior superior type and performed ESS. We introduced the CLAP flap after 2015 for the lateral type and some of the medial types of POMCs. We examined the cyst opening rate using computed tomography, age, sex, cyst position, and a follow-up period in four patients (five sides) who did not undergo flap surgery, but who were managed in our hospital in 2015, and in eight patients (nine sides) who underwent the CLAP flap technique in our hospital. In the group with the CLAP flap, the cyst opening rate was significantly higher (P < 0.05). The CLAP flap was effective for preventing postoperative bony regrowth. It may be one of the options for covering the exposed bone surface as widely as possible.

Abstract
BACKGROUND The olfactory cleft (OC) comprising the olfactory epithelium (OE) is the most important anatomical location for olfactory function. Endoscopic sinus surgery (ESS) is used to treat diseases related to the OC and improve olfactory dysfunction. However, iatrogenic OE injury occasionally occurs. Comprehensive knowledge of the olfactory region is required to avoid damage to the OE during endoscopic procedures. METHODS Immunohistochemistry was performed on olfactory mucosa obtained from the unaffected side of olfactory neuroblastoma surgical specimens. The OE was defined as the epithelium containing mature olfactory sensory neurons (OSNs). The distribution and cell kinetics of the OE were examined. RESULTS The OE was selectively localized to the anterior two-thirds of the superior turbinate (ST) and in the nasal septum (NS) just opposite to the ST; the OE was not detected within the mucosa of the superior meatus. The density of mature OSNs was high at the ethmoid tegmen but gradually decreased with distance from the ethmoid tegmen. The extent of cell death and proliferation was relatively even across the OE. Analysis of airflow profiles revealed that resection of inferior ST does not decrease airflow to the OC. CONCLUSION The results indicate that the distribution and degree of differentiation of mature OSNs are heterogenous throughout the OE. Epithelial resection of the anterior or superior ST has the potential to damage olfactory function. Resection of the inferior or posterior ST or widening of the superior meatus is a safer alternative that does not damage mature OSNs or alter airflow to the OC.

Abstract
Although inferior turbinectomy with submucosal resection effectively reduces the
volume of the inferior turbinate, there is room for improvement in surgical
procedures. Techniques have been developed to reduce crusting and bleeding while
efficiently achieving volume reduction. State-of-the-art procedures pertaining
to the local injection site, incision line, exposure of the periosteum,
submucosal outfracture of the turbinate bone, trimming of redundant mucosa, and
incision line suturing are described. Pre and postoperative Nasal Obstruction
Symptom Evaluation (NOSE) scores and postoperative inferior turbinate bleeding
and crusting were evaluated. For the 18 consecutive patients analyzed, the pre
and postoperative NOSE scores were 67.8 ± 14.8 and 16.1 ± 13.0, respectively
(P = .0002). Postoperatively, bleeding was absent, and only
minor suture thread crusting was observed in 13 patients. In conclusion, our
novel technique improves the effectiveness of surgery as well as the
postoperative quality of the inferior turbinate.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a common disease, and endoscopic sinus surgery (ESS) is widely performed. However, there is no consensus regarding postoperative pain control after ESS, and postoperative opioid abuse is a problem in many countries. Acetaminophen is reportedly effective for postoperative pain control. Preemptive analgesia has received more attention lately, wherein pain is prevented before it occurs. In this study, we assessed the use of acetaminophen for preemptive analgesia during the perioperative period in ESS. METHODOLOGY This is a retrospective study of 175 patients who underwent ESS, septoplasty, and bilateral inferior turbinate mucosal resection at our hospital from April 2016 to February 2018. In total, 82 patients received 1,000 mg of acetaminophen during surgery and 4 hours after the first dose, while 93 patients did not receive it routinely. We compared these two groups. The primary outcome was the need to use additional analgesics prescribed by the ward physician and the secondary outcomes included postoperative pain, postoperative bleeding, reoperation, blood pressure, and body temperature. RESULTS The use of additional oral and intravenous analgesics was significantly reduced in the patients who received acetaminophen perioperatively. CONCLUSION Preemptive analgesia during the perioperative period of ESS could lead to satisfactory postoperative pain control.

Abstract
Objective The pterygopalatine fossa (PPF) is a narrow space situated posterior to the maxillary sinus. While external approaches have been used to treat tumors of the PPF, recent endoscopic approaches have become favored as an alternative; we developed an endoscopic tri-port approach, which provides wide surgical corridor with minimal invasion, for PPF. This report aims to introduce and verify the new approach. Design Case series. Setting A tertiary referral hospital. Participants We reviewed 11 patients with PPF or orbital tumors who were treated with the endoscopic tri-port approach. Main Outcome Measures Accessing tri-port approach's effects and limitations. Results When the tumor was located in the PPF or orbit without intracranial invasion, en bloc resection was achieved in six patients. With the exception of one patient, the nasal septum was preserved if not used for skull base reconstruction. If not invaded by a tumor or necessary for reconstruction, the inferior and middle turbinates were preserved. Conclusion The endoscopic tri-port approach provides an excellent surgical view and wide corridor and not requires an external approach, including a gingival incision.

Abstract
Resection of the olfactory mucosa (OM) is sometimes unavoidable during surgery; however, it is not known whether the OM can completely recover thereafter. The aim of this study was to uncover whether the OM fully recovers after mucosal resection and describe the process of OM regeneration. 8-week-old male Sprague–Dawley rats (n = 18) were subjected to OM resection at the nasal septum; six rats were euthanized for histological examination 0, 30, and 90 days after surgery. Immunohistochemistry was performed to identify olfactory receptor neuron (ORN) lineage cells [mature and immature ORNs and ORN progenitors, and olfactory ensheathing cells (OECs)], as well as dividing and apoptotic cells. Squamous and respiratory metaplasia and inflammatory cell infiltration were also assessed. On day 30 after resection, the mucosa had regenerated, and mainly contained thin nerve bundles, basal cells, and immature ORNs, with a few mature ORNs and OECs. On day 90, the repaired nasal mucosa had degenerated into stratified squamous or ciliated pseudostratified columnar epithelia, with reducing ORNs. The lamina propria contained numerous macrophages. Partial regeneration was observed within 1 month after OM resection, whereas subsequent degeneration into squamous and respiratory epithelia occurred within 3 months. Given the poor persistence of ORNs and OECs, OM resection is likely to result in olfactory impairment. Overall, surgeons should be cautious not to injure the OM during surgery.

Abstract
To retrospectively evaluate our treatment algorithm and surgical approaches for nasal fibro-osseous lesions at our hospital. Fifteen patients with nasal fibro-osseous lesions treated from January 1, 2010, to January 31, 2020 were included. Among them, 13 patients who underwent surgery were divided into groups A and B, based on whether they were treated before or after the treatment algorithm was established. The extent of the lesion, surgical approach, and outcomes, including bone regrowth assessed postoperatively using computed tomography at 6 months, were analyzed. In group A, six cases were treated via endoscopy and two via a combined endoscopy and external approach. In group B, three cases were treated via endoscopy, one via combined endoscopy and external approach, and one combined with craniotomy. Two group A cases and no group B cases had residual lesions postoperatively. Postoperative bone regrowth occurred in three group A patients and no group B patients. Multi-angled approaches for nasal fibro-osseous lesions based on the unified treatment algorithms used in the study may lead to a reduction in postoperative recurrence and complication rates.

Abstract
PURPOSE Caudal septoplasty is a difficult procedure. The cutting and suture technique is suitable for caudal septoplasty, but a batten graft is always necessary and bears the risk of nasal tip projection loss. We established a modified cutting and suture technique (MCAST), without using a batten graft, and investigated its effectiveness in correcting nasal obstruction and preventing nasal tip projection loss. METHODS We retrospectively reviewed the medical records of 22 patients who underwent caudal septoplasty using MCAST. Subjective assessment by Nasal Obstruction Symptom Evaluation (NOSE) score and objective assessment by computed tomography (CT) were performed before and after the surgery. For evaluating nasal tip projection, we asked patients about their awareness of external nasal deformity. Additionally, the nasal tip projection was measured by CT and compared before and after surgery. RESULTS The median preoperative NOSE score reduced significantly after MCAST (P < 0.001). On CT, the ratio of the area of the convex side to that of the concave side in the anterior portion of the nasal cavity increased significantly after MCAST (P < 0.001). All patients were unaware of external nasal deformity. There were no significant differences in the mean preoperative and postoperative nasal tip height and nasolabial angle. The mean supra tip height was significantly greater postoperatively than preoperatively (P = 0.02). CONCLUSIONS The MCAST was useful for correcting nasal obstruction with caudal septal deviation. There was no postoperative loss of nasal tip projection. The MCAST can be suitable for correcting C-shaped caudal deviations without dislocating the caudal septum from the anterior nasal septum.

Abstract
Loss of olfactory sensory neurons (OSNs) after injury to the olfactory epithelium (OE) triggers the generation of OSNs that are incorporated into olfactory circuits to restore olfactory sensory perception. This study addresses how insulin receptor-mediated signaling affects the functional recovery of OSNs after OE injury. Insulin levels were reduced in mice by ablating the pancreatic β cells via streptozotocin (STZ) injections. These STZ-induced diabetic and control mice were then intraperitoneally injected with the olfactotoxic drug methimazole to selectively ablate OSNs. The OE of diabetic and control mice regenerated similarly until day 14 after injury. Thereafter, the OE of diabetic mice contained fewer mature and more apoptotic OSNs than control mice. Functionally, diabetic mice showed reduced electro-olfactogram (EOG) responses and their olfactory bulbs (OBs) had fewer c-Fos-active cells following odor stimulation, as well as performed worse in an odor-guided task compared with control mice. Insulin administered intranasally during days 8-13 after injury was sufficient to rescue recovery of OSNs in diabetic mice compared with control levels, while insulin administration between days 1 and 6 did not. During this critical time window on days 8-13 after injury, insulin receptors are highly expressed and intranasal application of an insulin receptor antagonist inhibits regeneration. Furthermore, an insulin-enriched environment could facilitate regeneration even in non-diabetic mice. These results indicate that insulin facilitates the regeneration of OSNs after injury and suggest a critical stage during recovery (8-13 d after injury) during which the maturation of newly generated OSNs is highly dependent on and promoted by insulin.

Abstract
BACKGROUND Strong eosinophil infiltration in chronic rhinosinusitis with nasal polyp (CRSwNP) is highly associated with recalcitrance and higher nasal polyp recurrence rate after surgery. The prevalence of eosinophilic CRSwNP (ECRS) is increasing in Asian countries including Japan. Benralizumab is a humanized anti-IL-5R alpha monoclonal antibody that depletes eosinophils by antibody-dependent cell-mediated cytotoxicity. OBJECTIVE To assess the efficacy and safety of benralizumab in patients with ECRS. METHODS This phase II, randomized, double-blind, placebo-controlled study was conducted in Japan. Patients were randomized 1:2:2 to placebo, a single administration of benralizumab 30 mg, or benralizumab 30 mg every 4 weeks (q4w) for a total of three doses. The primary endpoint was the change in nasal polyp score from baseline at Week 12. RESULTS Overall, 56 patients were enrolled (placebo, n = 11; benralizumab single dose, n = 22; benralizumab q4w, n = 23). Although the mean total nasal polyp score began to decrease after the initiation of benralizumab treatment, there were no statistically significant differences in change in nasal polyp score from baseline at Week 12 between benralizumab and placebo (placebo, -0.5 ± 0.8; benralizumab single, -0.3 ± 0.8; benralizumab q4w, -0.5 ± 1.5). Post-hoc analysis showed that the administration of benralizumab decreased nasal polyp scores ≥2 points in 42.2% of ECRS patients and that patients with high blood eosinophil levels had a greater tendency to respond to benralizumab treatment. The safety profile was similar to that in previous studies and no unexpected adverse events were noted. CONCLUSION Although benralizumab did not meet the primary efficacy endpoint, reductions of nasal polyp scores were seen in the benralizumab group compared with the placebo group over the whole study period, especially in patients with high levels of blood eosinophils.

Abstract
Background: Visual complications of endoscopic sinus surgery usually occur during or immediately after the surgery. We report a case of cavernous carotid aneurysm which developed and gradually worsened after endoscopic sinus surgery was performed. Case presentation: A 63-year-old woman with chronic rhinosinusitis resistant to conservative treatment underwent endoscopic sinus surgery. Despite the surgery being successful and without complications, diplopia developed 2 weeks later. Intracranial ima- ging revealed a giant cavernous carotid aneurysm as a likely cause of the diplopia. The patient underwent endovascular stenting treatment, and the diplopia was consequently reduced. Conclusions: We experienced a rare case of cavernous carotid aneurysm which started to develop 2 weeks after endoscopic sinus surgery. Possible causes of the aneurysm in this patient are an indirect effect of surgery, such as perioperative hypertension, and bacterial sinusitis.

Abstract
OBJECTIVE Hangeshashinto is a Japanese Kampo medicine applied for the treatment of oral mucositis and gastroenteritis. Hangeshashinto exhibits broad-spectrum antibacterial activity and suppresses prostaglandin (PG)E2 production in the mucosa and has the ability to improve the inflammatory condition. In addition to these effects, because cAMP, a composition of Hangeshashinto, facilitates ciliary beat, Hangeshashinto could also improve the physiological function of the nasal mucosa, consist of ciliated epithelium, but details were unknown. METHODS This study was aimed to investigate the effects of Hangeshashinto on the nasal mucosa. Healthy nasal mucosal sections were collected from the nasal septum of ten Japanese white rabbits, placed in a collagen dish for tissue culture, and rinsed with two different concentrations of Hangeshashinto solution (1.0%, n = 10 and 2.5%, n = 10) and cAMP solution (50µM, n=10 and 100 µM, n=10) or saline (control, n = 10). Ciliary beat frequency (CBF) as a physiological function of the nasal mucosa was recorded at 1, 3 and 7 days after rinsing, and histological evaluation of epithelial damage was performed at 7 days after rinsing. RESULTS CBF in the 1.0% but not in the 2.5% Hangeshashinto group, increased at 3 and 7 days compared with that in the control group (p < 0.05). This trend was also observed in the CBF in the 100 µM cAMP group, significant difference was not observed between the CBF of the 1.0% Hangeshashinto group and the 100 µM cAMP group at 1, 3 and 7 days after rinsing (p > 0.05). Histological score only in the 2.5% Hangeshashinto group was lower than that in the control group (p < 0.05), while a significant decline was not observed in the other groups compared to that in the control group (p > 0.05). CONCLUSION Our results suggest that 1.0% Hangeshashinto solution facilitates the physiological function of the nasal mucosa by promoting ciliary functions without histological damage of cilia epithelium. When applied with the appropriate concentration, Hangeshashinto could have ability to improve the physiological functions of the nasal mucosal epithelium.

Abstract
BACKGROUND The prelacrimal approach, termed endoscopic modified medial maxillectomy (EMMM), has recently been applied for treatment of inverted papilloma (IP) in the maxillary sinus. EMMM provides wider access to the maxillary sinus while preserving the inferior turbinate and nasolacrimal duct. METHODS We reviewed patients with IP in the maxillary sinus to compare the surgical results obtained by conventional surgery (ie, endoscopic maxillary sinus antrostomy or in combination with the Caldwell-Luc approach) with those obtained by EMMM. RESULTS All patients had a T3 on the Krouse staging system, and the average follow-up time was 46.0 months. Of the 18 patients in the conventional group, recurrence was seen in 3 patients (16.6%). No recurrence was seen in the 27 patients who showed preservation of the inferior turbinate and nasolacrimal duct, and no complications occurred in the EMMM group. CONCLUSIONS EMMM is an effective surgical approach that reduces recurrence with fewer complications.

Abstract
BACKGROUND Topical application of vasoconstrictors is necessary for endoscopic sinus surgery (ESS) for a bloodless surgical view and reduced intraoperative bleeding. We aimed to verify the effectiveness of gauze placement soaked with adrenaline at suprabullar recess, where the anterior ethmoidal artery exists, on hemostasis during ESS. METHODS A randomized, double-blinded trial was carried out for 26 patients receiving ESS. At the beginning of the surgery, gauze soaked with 2% lidocaine with or without 1:10 000 adrenaline was placed at the suprabullar recess for 8 minutes. Estimated blood loss, surgical field score, and operation time were compared between the two groups. RESULTS Estimated blood loss and surgical field score were significantly smaller in the adrenaline group than in the no adrenaline group. Operation time was not significantly different between the two groups. CONCLUSION Gauze placement soaked with adrenaline at suprabullar recess reduces estimated blood loss and clears the surgical field during ESS.

Abstract
PURPOSE Attention to the inclination of lamellas attached to the skull base, including the basal lamella of the middle turbinate, facilitates the intraoperative identification of each lamella without requiring the use of a navigation system. We classified the inclination between the lamella and the skull base in preoperative computed tomography (CT) images and examined the relationship between the lamellas attached to the skull base, including the basal lamella of the middle turbinate, and the position of the anterior ethmoidal artery (AEA). We aimed to develop a preoperative classification to help prevent intraoperative injury of the AEA. METHODS We retrospectively investigated the paranasal sinus sagittal section CT slices of 366 sides of 183 patients to assess the inclination of lamellas attached to the skull base and the AEA location. We also reviewed the AEA position, its correlation with the supraorbital ethmoid cell, and the lateral lamella of the cribriform plate. RESULTS We classified the lamella inclination at the skull base as the anterior direction, perpendicular direction, and posterior direction types. Lamellas containing a floating AEA inclined in the anterior direction toward the skull base were observed in 68.9% of sides, inclination in the perpendicular direction was noted in 30.5% of sides, and inclination in the posterior direction was noted in 0.5% of sides. CONCLUSION It is easier to identify the AEA intraoperatively when the lamella inclination of the skull base attachment is recognized based on preoperative CT findings. This approach could be applied to all paranasal sinus lamellas and assist in identifying the AEA and other nearby structures.

Abstract
OBJECTIVES/HYPOTHESIS Recent developments in reconstructive techniques for mucosal defects using mucoperiosteal materials have enabled rapid recovery of physiological function after endoscopic sinus surgery. Clinical trials have described the advantages, disadvantages, and different outcomes of free graft and pedicled flap, which, respectively, sacrifice or preserve blood flow. However, histological changes, that affect the postoperative outcomes after reconstruction, remain unclear. We created an animal model for the reconstruction of mucosal defects using free grafts and pedicled flaps, and evaluated them histologically. STUDY DESIGN Animal study. METHODS We created mucosal defects in the left nasal septum of 20 rabbits and performed reconstruction with free grafts and pedicled flaps. The distribution of ciliary and goblet cells at the reconstruction site was evaluated after 7 and 28 days using hematoxylin and eosin-stained sections to calculate the Ciliary Cell Index and Goblet Cell Index. The severity of inflammation was assessed using the Cartilage Inflammatory Cell Score. RESULTS Crusting and changes in the mucosal morphology at the reconstruction site occurred only in the free graft group. In addition, the pedicled flap group had significantly greater preservation of ciliary and goblet cells and less inflammatory cell infiltration into the septal cartilage (P < .05) than the free graft group. CONCLUSIONS After reconstruction procedures for mucosal defects, histopathological differences were observed between the free graft and pedicled flap. Reconstruction with pedicled flaps had advantages including preservation of healthy mucosal epithelium and suppression of inflammation on the reconstruction site. This indicated that reconstruction with pedicled flaps might have advantages over that with free grafts. LEVEL OF EVIDENCE NA Laryngoscope, 131:E428-E433, 2021.

Abstract
The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012. The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings. EPOS2020 contains chapters on definitions and classification where we have defined a large number of terms and indicated preferred terms. A new classification of CRS into primary and secondary CRS and further division into localized and diffuse disease, based on anatomic distribution is proposed. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, allergic rhinitis, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. All available evidence for the management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is systematically reviewed and integrated care pathways based on the evidence are proposed. Despite considerable increases in the amount of quality publications in recent years, a large number of practical clinical questions remain. It was agreed that the best way to address these was to conduct a Delphi exercise . The results have been integrated into the respective sections. Last but not least, advice for patients and pharmacists and a new list of research needs are included. The full document can be downloaded for free on the website of this journal: http://www.rhinologyjournal.com.

Abstract
BACKGROUND The defect after surgical resection of sinonasal malignant tumors is normally reconstructed using free flaps obtained from donor sites. There is no report of using the palatal island flap to reconstruct defects after surgery. We aimed to describe our technique of soft tissue reconstruction through anterior pedicled inferior turbinate (APIT) flap in conjunction with palatal flap for standard inferior maxillectomy with hard palate resection and its outcomes and to discuss its advantages and disadvantages compared with free-flap reconstruction. METHODS For resection of malignant tumors arising from the anterior nasal septum, we preserved the hard palate during maxillectomy using a palatal island flap and an anterior pedicled inferior turbinate flap. RESULTS One patient developed a small oroantral fistula, which was sealed with a denture. The other patient had a good outcome. CONCLUSION Our technique of maxillectomy is useful for selected cases of sinonasal malignancy that require maxillary floor resection.

Abstract
Rhinogenous optic neuritis, which causes neuropathy associated with visual dysfunction, greatly reduces patient quality of life and requires suitable early treatment. This study aimed to analyze visual outcome predictors in patients with rhinogenous optic neuritis and to develop and investigate the usefulness of an algorithm to facilitate early treatment. Prospective and retrospective investigations were conducted at the Department of Otorhinolaryngology. The visual outcomes after sinus surgery of 24 of 53 patients suspected of having rhinogenous optic neuritis were analyzed. Furthermore, the usefulness of the treatment algorithm was evaluated in 27 of these 53 patients. Data from 24 patients who underwent surgery were included in a multiple regression analysis to investigate the associations between visual outcomes and concomitant symptoms and the time from symptom onset to surgery. The mean time from the initial examination to a request for otorhinolaryngological examination to assess the usefulness of the treatment algorithm was compared in 27 patients who did not undergo an initial otorhinolaryngological examination. Visual acuity improved in 23 participants who underwent surgery. Multivariate analysis identified the time from onset to surgery and headache as significant predictors of postoperative visual acuity. The mean time from the initial examination to a request for otorhinolaryngological examination was significantly shorter after the algorithm was introduced (1.13 days, 8 patients; P = .008). Early surgical treatment is essential to avoid further postoperative visual acuity decreases in patients with rhinogenous optic neuritis. Patients who experience headache may have poorer postoperative outcomes.

Abstract
Transgenic rice seeds that contain genetically modified Cry j 1 and Cry j 2, the two major allergens of Cryptomeria japonica (Japanese cedar; JC), have been developed as immunotherapeutic candidates for JC pollinosis. Because the transgenic rice (TG-rice) seeds express allergens containing whole amino acid sequences of Cry j 1 and Cry j 2 in the endosperm tissue (edible part of rice grain), they can potentially target all Cry j 1- and Cry j 2-specific T-cells. However, it was unknown whether antigenicity of Cry j 1 and Cry j 2 could be completely preserved in TG-rice seeds. We verified the antigenicity of TG-rice seeds to T-cells through the analysis of the proliferative responses of T-cells in Cry j 1- or Cry j 2-immunized mice or T-cell lines to TG-rice seed extract. First, four mouse strains were immunized with Cry j 1 or Cry j 2. T-cells in the immunized mice proliferated on treatment with TG-rice seed extract, but not non-transgenic wild-type rice (WT-rice) seed extract. Furthermore, T-cell lines were established from the spleen cells of the immunized mice. Each T-cell line resulted in a proliferative response to TG-rice seed extract, but not to WT-rice seed extract, suggesting that TG-rice seeds certainly express T-cell epitopes corresponding to T-cell lines. Considering the modified amino acid sequences of Cry j 1 and Cry j 2 in TG-rice seeds, the expression of specific T-cell epitopes suggested that TG-rice seeds express all possible T-cell epitope repertoires of Cry j 1 and Cry j 2.

Abstract
OBJECTIVE A major drawback of the Killian incision is its inability to access the caudal septum and correct caudal septal deviation. Open and hemitransfixion septorhinoplasty are considered necessary in such cases. We developed a new septoplasty method that can be successfully applied in patients with mild caudal septal deviation. In this study, we evaluated the outcome of this technique. METHODS We prospectively collected data of 16 patients with mild caudal septal deviation who underwent endoscopic septoplasty between November 2015 and October 2017. A modified Killian incision was made on the concave side of the septum. The central part of the cartilage was preserved, and excess cartilage was resected; the central part of the cartilage was sutured to the caudal cartilage. RESULTS Postoperatively, the ratio of the area of the convex side to that of the concave side in the anterior portion of the nasal cavity was significantly improved, as revealed on CT analysis (p < 0.001). Nasal obstruction was significantly reduced or eliminated in all patients (p < 0.001). CONCLUSION The J septoplasty method for the correction of mild caudal septal deviation is easy to perform through a modified Killian incision, and seems to be useful in selected cases.
