Abstract
BACKGROUND Platelet-rich plasma (PRP) and its combined therapeutic modalities have catalyzed new possibilities in dermatology; however, limitations in evidence and lack of consensus remain among clinicians regarding optimal composition, protocol, technique, and application. OBJECTIVE To provide an update and analysis of the evidence for PRP in hair restoration and skin rejuvenation through review of recent available data, highlighting controversies and expert insights to guide future studies, and stimulate discourse and innovations benefitting patients. METHODS A structured review and expert analysis of PubMed publications before October 2023, with a focus on recent literature from January 2020 through October 2023. RESULTS AND CONCLUSION Growing literature supports the utility and benefits of PRP and related autologous products for applications for skin and hair, with strongest evidence for androgenetic alopecia and skin rejuvenation. However, this is limited by lack of consensus regarding best practices and protocols. Randomized, controlled trials with uniform metrics comparing outcomes of various compositions of autologous blood products, preparation methods, dosimetry, and frequency of treatments are still required. This will allow the medical discourse to grow beyond the realm of expert opinion into consensus, standardization, and more wide spread adoption of best practices that will benefit patients.

Abstract
BACKGROUND This study compares frontal QRS-T angle (fQRS-T) in electrocardiogram (ECG) examinations of people with nasal septal deviation (NSD) with healthy controls (HC). METHODS Eighty-two patients whom a radiologist with paranasal computed tomography definitively diagnosed with NSD were included in the study. 101 individuals without NSD were selected as HC. RESULTS Compared to the HC group, the fQRS-T in was considerably wider in patients with NSD (p < .001). According to Spearman correlation analysis, fQRS-T and NSD angle, and platelet lymphocyte ratio (PLR) were significantly correlated (p = .021, p < .001, and p = .003, respectively). In linear regression analysis where the fQRS-T was taken as a dependent variable, NSD angle and PLR predicted the fQRS-T significantly and positively (F(5.76) = 8.451, R2 = 0.357, Adjusted R2 = 0.315 and p < .001). CONCLUSION In this study, fQRS-T was significantly higher in patients with NSD. In future studies, fQRS-T can be compared before and after septoplasty in NSD patients.

Abstract
Nasal obstruction due to Deviated Nasal Septum (DNS) is a commonly encountered condition by the Otorhinolaryngologist. This leads to chronic hypoxia which in turn leads to stimulation of platelets. This change can be assessed by estimation of the Mean Platelet Volume (MPV) which is a commonly available investigation while ordering a haemogram. As there is a lot of conflicting data about the relationship between DNS and MPV, this study was undertaken to evaluate if there is a relationship between these two parameters. A 1-year observational study was done and after adhering to the inclusion and exclusion criteria, there were 50 cases of deviated nasal septum and 50 controls who attended the ENT Out-Patient Department of a tertiary care hospital who were evaluated. Blood was drawn and the Mean Platelet Volume was estimated. It was found that there was no statistical significance between the cases and controls. Contradictory to other studies done in literature, our study did not find any correlation. This could be due to the type of septal deviation cases that were part of our study. Hence, multicentric studies with larger samples need to be studied in order to establish sound conclusions.

Abstract
BACKGROUND It is known that nasal septal deviation (NSD) has negative effects on the cardiovascular system, but the possible pathophysiological mechanisms of these effects still need to be explained. The aim of this study was to investigate the endothelial dysfunction (ED) caused by NSD and the effects of septoplasty on it. METHODS The study included 40 patients between the ages of 18 to 50 years with a marked NSD indication for septoplasty and 40 healthy age-and gender-matched individuals. Nasal obstruction symptom evaluation scale was used to evaluate the severity of nasal obstruction and the effectiveness of septoplasty. All participants underwent detailed cardiac examination and ultrasonographic measurement of flow-mediated dilatation (FMD). The same cardiac evaluations and nasal obstruction symptom evaluation scale assessments were repeated in the patient group at the postoperative 3rd month. RESULTS The mean FMD value in the control group was significantly higher than preoperative FMD in the patient group (9.1 ± 2.9 versus 7.6 ± 2.4, P = 0.024). In the patient group, preoperative and postoperative FMD values were measured as 7.6 ± 2.4 and 9.0 ± 2.7, respectively, and there was a significant difference between them (P = 0.032). There was no significant difference in FMD values between the control group and postoperative patient group (P = 0.925). CONCLUSIONS This study shows that NSD can cause ED, which is a precursor of atherosclerosis, and that successful septoplasty can improve ED.

Abstract
BACKGROUND Oxidative stress plays a role in the pathogenesis of many chronic diseases. Upper airway obstruction has been identified as a risk factor for increased oxidative stress-related disorders such as obstructive sleep apnea. The effect of adenotonsillar hypertrophy, which may result in a narrowing of the upper airways, on oxidative stress can be a valuable subject of research. This study aimed to investigate the efficacy of adenotonsillectomy on oxidative stress evaluated using the thiol / disulfide balance. METHODS Thirty children who underwent adenotonsillectomy and 30 healthy controls, all aged from 3 to 18 years, were included in the study. Blood samples were taken preoperatively and 3 months postoperatively in the study group; in the control group, baseline blood samples were taken and samples were again taken 3 months later. Thiol / disulfide homeostasis items were analyzed. Antioxidant markers were native thiol, total thiol, and native / total thiol. Oxidative stress markers were disulfide, disulfide / native thiol, and disulfide / total thiol. RESULTS At the preoperative period, oxidative stress parameters of thiol / disulfide homeostasis were higher in the study group than in the control group (P < 0.05) and antioxidant activity parameters were lower than in the control group (P < 0.05). Three months postoperatively, oxidative stress parameters were lower than in the control group (P < 0.05), and antioxidant parameters were no different from those in the control group (P > 0.05). In the adenotonsillectomy group considered separately, oxidative stress markers of disulfide and disulfide / native thiol decreased (P < 0.05) and antioxidant markers of native thiol and total thiol increased in the postoperative measurements (P < 0.05). CONCLUSIONS Oxidative stress related to adenotonsillar hypertrophy decreased after adenotonsillectomy. The antioxidant parameters of the thiol homeostasis increased after adenotonsillectomy. We concluded that adenotonsillectomy operations should be planned and applied timeously to prevent the adverse effects of adenotonsillar hypertrophies on thiol homeostasis.

The Relationship between the Mean Platelet Volume and Carotid Atherosclerosis and Prognosis in Patients with Acute Cerebral Infarction. BIOMED RESEARCH INTERNATIONAL 2020; 2020:6685740. [PMID: 33490251 PMCID: PMC7790567 DOI: 10.1155/2020/6685740] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Revised: 12/21/2020] [Accepted: 12/23/2020] [Indexed: 02/06/2023]
Abstract
Objective To investigate the relationship between mean platelet volume (MPV) level and carotid atherosclerosis and prognosis in patients with acute cerebral infarction. Methods. A retrospectively included 160 patients with acute cerebral infarction classified by TOAST classification as aortic atherosclerosis as the observation group. To analyze the relationship between MPV and carotid atherosclerosis, and use receiver operating characteristic (ROC) curves to analyze the role of MPV in predicting the prognosis of acute cerebral infarction in the observation group, grouping patients with different MPV by cut-off value, and analyze the differences in factors between the two groups of patients. Results MPV has a positive correlation with carotid atherosclerosis in patients with acute cerebral infarction. Multivariate logistic regression analysis revealed that increased MPV was an independent predictor of poor functional outcome in patients with acute cerebral infarction (Odds Ratio (OR): 6.152, 95% CI: 2.385-13.625, P < 0.01). ROC curve analysis showed that the area under the curve for MPV to predict poor prognosis was 0.868 (95% CI: 0.787-949, P < 0.01). The cutoff value, sensitivity, and specificity were 12.65, 76.2%, and 87.6%. Compared with patients with MPV < 12.65 at admission, patients with higher MPV levels (MPV ≥ 12.65) at admission have larger infarct size, more severe carotid artery stenosis, poor short-term prognosis, and higher mortality. Conclusion MPV level is closely related to the degree of carotid atherosclerosis in patients with acute cerebral infarction, and it is also an independent predictor of poor prognosis in patients with acute cerebral infarction at 3 months.

Abstract
The nose plays both an aesthetic and functional role in the human body. Physiologically, the nose is an important part of the upper airway. Aesthetically, it is the central focal point of the face. Thus, rhinoplasty has evolved to be both an aesthetic and functional surgery, as the manipulation of the aesthetic subunits of the nose inadvertently leads to the functional alterations of the nose. While the aesthetic goals of rhinoplasty are well described in the literature, functional outcomes from rhinoplasty have been more challenging to delineate. Rhinoplasty can have an impact on the sense of smell, sleep apnea, oxygenation, cognitive function, cardiovascular function, and voice. We have systematically reviewed the current literature in regard to functional rhinoplasty and septoplasty to summarize current surgical maneuvers and their impact on nasal function, along with physiological and perceived functional changes from rhinoplasty.

Abstract
AIM To investigate the effect of septoplasty in patients with nasal septum deviation (NSD) on erythropoietin (EPO) and hemoglobin (Hgb) levels. METHODS Between 2017 December and 2018 May, 47 patients with NSD who underwent septoplasty in Adiyaman University Medical Faculty Department of Otorhinolaryngology included in this prospective study. The changes in EPO and Hgb levels were studied before and 3 months after the surgery. RESULTS The mean age of the patients studied was 30.7 ± 9.9. 31 of the patients were male and 16 were female. Pre- and post-operative 3rd month mean EPO levels of the patients were 11.45 ± 4.9 Mu/mL and 11.39 ± 6.02 Mu/mL, respectively. When these values were analyzed, no statistically significant difference was found (P = .93). Pre- and post-operative 3rd month mean Hgb levels were 14.6 g/dL, and 14.6 g/dL, in turn. When these values were analyzed, no statistically significant difference was found (P = .68). CONCLUSION According to these results, the author can say there is no statistically significant relationship between NSD and EPO or Hgb. Therefore, this issue will be enlightened with future studies including more patients and objective tests evaluating nasal patency.

Abstract
PURPOSE Platelet-rich plasma (PRP) is an autologous prepared plasma enriched with platelets and obtained after a centrifugal separation and aggregation procedure. However, the optimized preparation protocol for PRP is still controversial and there are no standardized preparation protocols. The aim of this study is to show the effect of time and force of the centrifugation on the concentrations of platelets and to optimize the effective PRP preparation protocol. METHODS For the study, whole blood was drawn into 24 different 6-ml standard tubes containing 0.6 ml anticoagulant citrate dextrose solution-formula A. The samples were centrifuged separately at forces of 45×g, 180×g, 400×g, 725×g, 1130×g and 1630×g for 5, 10, 15 and 20 min. Every sample was analyzed, and a comparison was made between all groups. RESULTS No significant difference was observed in terms of platelet concentration, mean platelet volume or platelet mass between all groups (p > 0.05). The mean ± SD of platelet mass in baseline is 1890 ± 134 × 103 fL/μL. The mean ± SD of platelet mass in the high centrifugal force of 1630×g was 3395 ± 564 × 103 fL/μL, 2638 ± 425 × 103 fL/μL, 2355 ± 449 × 103 fL/μL and 2109 ± 41 × 103 fL/μL over times of 5, 10, 15 and 20 min, respectively. The mean ± SD of platelet mass in the low centrifugal force of 45×g was 2002 ± 1623 × 103 fL/μL, 2491 ± 1591 × 103 fL/μL, 2611 ± 876 × 103 fL/μL and 3003 ± 511 × 103/μL over times of 5, 10, 15 and 20 min, respectively. CONCLUSIONS Platelets should be evaluated with platelet mass not including platelet concentrations alone, but also with mean platelet volume, which symbolizes the size of platelets while comparing platelet-rich plasma preparation protocols and kits. This could be a new starting point for comparison of PRP for all applications in the literature. All centrifugation forces and times could produce biologically reactive PRP. It may be only suggested that if high acceleration force is used, low durations should be selected, or if low acceleration force is used, long time of centrifugation should be selected.

Abstract
OBJECTIVES This study aimed to assess the effect of nasal septoplasty in patients with marked nasal septal deviation (MNSD) on subjective perception of nasal patency, echocardiography, and hematologic parameters. METHODS Seventy-nine consecutive patients (mean age, 29.9 ± 9.7 years; 57 men and 22 women) at least 18 years old were diagnosed as MNSD consistent with presenting symptom of chronic nasal obstruction lasting at least 3 months. Complete blood count measurement to assess mean platelet volume (MPV) and neutrophil to lymphocyte ratio (NLR), the Nasal Obstruction Symptom Evaluation (NOSE) questionnaire, and echocardiography were performed for all patients just before and at postoperative third month of septoplasty. RESULTS The MPV (0.021), NLR (<0.001), and NOSE (<0.001) were all significantly decreased, and global longitudinal strain (GLS) value (<0.001) were also significantly increased at postoperative third month. Correlation analysis also indicated that ΔNLR was positively correlated with ΔGLS (r = 0.385, P < 0.001), and ΔNOSE (r = 0.436, P < 0.001), and correlated negatively with the ΔMPV (r = -0.302, P = 0.024). ΔGLS was also positively correlated with the ΔNOSE (r = 0.769, P < 0.001). CONCLUSION Septoplasty for MNSD could provide not only alleviation of otorhinolaryngologic symptoms but also improvement in subclinical left ventricular systolic dysfunction and decline in MPV and NLR levels.

Abstract
Recent years, the discussion about whether platelets participant in the development of sudden sensorineural hearing loss (SSHL) continues and many studies on the relationship between them have come to our attention. Some studies believe that platelet parameters have significantly changed in patients with SSHL, while some not, controversially. Therefore, to investigate the association between platelet parameters, including mean platelet volume (MPV), platelet distribution width (PDW) and platelet count (PLT), and SSHL, expecting to resolve controversy and provide clinical evidence for diagnosis and monitoring of SSHL. Basic methods: Literature was retrieved searching electronic databases (PubMed, Embase, Cochrane, and Scopus) and searching references of related articles by hand. A total of 18 case-control studies involving 1837/1734 subjects (SSHL/control) were included. Meta-analysis showed there was no difference between the patients who suffered SSHL and healthy controls in MPV level [standard mean difference (SMD) (95% confidence interval (CI)) = 0.16 (-0.07, 0.40), I2 = 80%, P<0.00001] and PLT [SMD (95% CI) = -0.03(-0.18, 0.12), I2 = 73%, P<0.00001]. While PDW exhibited significant difference [SMD (95% CI) = 0.85 (0.20, 1.49), I2 = 93%, P<0.00001]. Subgroup analysis about geographical area suggested PLT have obvious evidence for SSHL in Eastern country [SMD (95% CI) = 0.23 (0.14, 0.33), I2 = 0%, P=0.81]. Our study did not support a correlation between MPV and SSHL, while PLT may have clinical significance for SSHL in Eastern country. With insufficient data to explore the resource of heterogeneity for PDW, there is no decisive conclusion reached.

Abstract
We explored possible relationships between sudden sensorineural hearing loss (SSNHL) in patients differing in terms of audiographic data and the levels of vascular markers in routine blood data.We included 37 patients with low-frequency SSNHL (LF-SSNHL), 28 with high-frequency SSNHL (HF-SSNHL), 32 with all-frequency SSNHL (AF-SSNHL), 32 with total-deafness SSNHL (TD-SSNHL), and 31 age- and sex-matched healthy controls. Peripheral venous blood samples were collected, and routine blood parameters including platelet and lymphocyte count, mean platelet volume (MPV), and platelet-to-lymphocyte ratio (PLR) were measured. Each group was divided into recovery subgroup and unrecovery subgroup in accordance with hearing level after 1 month therapy, then compared the difference of platelet and lymphocyte count, MPV, and PLR between the 2 subgroups.No significant difference was observed between platelet count of all SSNHL patients and control group (all P > .05). MPV of AF-SSNHL and TD-SSNHL, PLR of all SSNHL patients were significantly higher than those of control group (all P < .05), while lymphocyte count of all audiographically distinct SSNHL patients was significantly lower than that of control group (all P < .05). However, the difference of platelet count, lymphocyte count, MPV, and PLR among audiographically distinct SSNHL patients was not significant (all P > .05). In HF-SSNHL patients, lymphocyte count of unrecovery subgroup was significantly lower, while MPV and PLR of the unrecovery subgroup were significantly higher than those of recovery subgroup (all P < .05). In AF-SSNHL patients, MPV of the unrecovery group was significantly higher than that of recovery subgroup (P < .05).Lymphocyte count, MPV, and PLR may be relative to SSSNHL, but they could not be used to distinct SSNHL audiographically. Lower lymphocyte, higher MPV, and PLR may be indicative for the prognosis of HF-SSNHL patients; higher MPV may be related to bad treatment outcome of AF-SSNHL patients.

Abstract
OBJECTIVE Nasal septum deviation may affect cardiopulmonary system. Those effects can be determined via blood tests and Epworth sleepness scale (ESS). In this study, it was aimed to measure mean platelet volume (MPV) and platelet distribution width (PDW) in patients with nasal septum deviation and to assess changes at their levels after septoplasty. Furthermore, it was purposed to document the correlation between ESS score and MPV, PDW levels. METHODS Eighty-one patients who underwent septoplasty and 50 healthy controls composed the study group. Epworth sleepness scale was performed to all patients preoperatively and patients were divided into 2 groups in terms of ESS scores. Mean platelet volume and PDW levels were measured preoperatively and it was repeated postoperatively. RESULTS In Group A (ESS <10), MPV reduced from 8.48 ± 0.38 fl to 8.47 ± 0.36 fl (P >0.05), PDW reduced from 14.56 ± 1.27% to 14.43 ± 1.03% after surgery (P >0.05). On the other hand, in Group B (ESS ≥10), MPV reduced from 9.54 ± 0.68 fl to 8.87 ± 0.44 fl (P <0.001), PDW reduced from 17.15 ± 1.75% to 15.35 ± 1.29% postoperatively (P <0.001). CONCLUSIONS Statistically significant improvements at MPV and PDW levels after surgery were noticed only at patients with excessive daytime sleepness whose ESS score was 10 or above. According to this, it would be preferable to operate these patients earlier to protect them from systemic effects.

Abstract
INTRODUCTION Studies on Mean Platelet Volume (MPV) in children with Sleep Disordered Breathing (SDB) report conflicting results and the hypothesis of an intermittent hypoxemia leading to a systemic inflammation is reaching consensus. Vitamin D exerts anti-inflammatory properties and its deficiency has been supposed to play a role in sleep disorders. Emerging interest is rising about Primary Snoring (PS) since it is reasonable that also undetectable alteration of hypoxia might predispose to an increased production of inflammatory mediators. In this perspective, in a group of children affected by SDB, our aim was to investigate MPV, vitamin D and C Reactive Protein (CRP) levels, which had been previously evaluated separately in different studies focused only on Obstructive Sleep Apnea Syndrome (OSAS). MATERIALS AND METHODS We enrolled 137 children: 70 healthy controls (HC), 67 affected by SDB undergoing a polysomnographic evaluation, 22 with a diagnosis of PS and 45 with a diagnosis of OSAS. All patients underwent routine biochemical evaluations including blood cell counts, CRP and vitamin D. RESULTS Children affected by SDB had a mean age of 8.49±2.19 and were prevalently males (23 females, 34%; 44 males, 66%). MPV levels were higher in OSAS and PS when compared to HC; platelet count (PLT) and CRP levels were higher while Vitamin D levels were lower in children with SDB when compared to HC. MPV levels were correlated with PLT (r = -0.54; p<0.001), vitamin D (r = -0.39; p<0.001) and CRP (r = 0.21; p<0.01). A multiple regression was run to predict MPV levels from vitamin D, CRP and PLT and these variables significantly predicted MPV (F = 17.42, p<0.0001; adjusted R2 = 0.37). Only platelet count and vitamin D added statistically significantly to the prediction (p<0.05). CONCLUSION The present study provides evidence of higher MPV and lower vitamin D levels in children with PS as well as in children with OSAS, and supports the underlying inflammation, hence, highlighting the importance of an early diagnosis of this previously considered benign form of SDB.

Abstract
Adenoid hypertrophy (AH) is a common disorder in children, resulting in chronic nasal congestion. This chronic congestion should be evaluated carefully because it can lead to chronic upper airway obstruction. Many authors have suggested that increased nasal resistance to respiration may cause disturbances in the pulmonary ventilation and carry the risk of cardiopulmonary diseases. Mean platelet volume (MPV) is a marker of platelet function and is positively associated with indicators of platelet activity. Mean platelet volume is an indicator of larger and more reactive platelets and has been shown to be increased in patients with vascular disease, including peripheral, pulmonary, and coronary artery disease. Recently, MPV levels have also been shown to be increased in patients with severe obstructive sleep apnea, and marked nasal septal deviation. Moreover, increased MPV has also been shown to have a prognostic role in cardiovascular disease. We investigated whether MPV is higher in patients with AH and whether higher MPV levels can be reduced by adenoidectomy. To the best of our knowledge, this is the first study to investigate MPV in patients with AH. Our results suggest that MPV, a determinant of platelet activation, is elevated in patients with AH and adenoidectomy is an effective therapeutic measure in such patients. Increased platelet activation may be related to an increase of cardiopulmonary risk in patients with AH.

Abstract
Nasal obstruction is a common cause of marked nasal septal deviation. It is related strongly with hypoxia. Hypoxic conditions increase mean platelet volume levels. This study aimed to investigate the effect of age on mean platelet volume in patients with marked nasal septal deviation. We made a retrospective study of patients with marked nasal septal deviation between January 2012 and May 2014. The patients were divided into four groups according to duration of nasal obstruction (less than 10, 10-20, 20-30 and more than 30 years). The groups were compared with each other in terms of mean platelet volume, platelet distribution width, platelet count in preoperative hemogram. This study was performed on 356 male and 139 female patients. Mean age was 33.9 ± 12.3 years. It was determined that the platelet count, mean platelet volume did not constitute statistically significant difference between groups (p > 0.05). Nevertheless, it was determined that as the duration of nasal obstruction elongated the mean platelet volume value increased and platelet count values decreased. Mean values of platelet distribution width constituted statistically significant difference between all groups (p = 0.026). Patients with marked nasal septum deviation should be subjected to surgery as soon as possible because of the increase in mean platelet volume and platelet distribution width values which are related to increase in the risk of cardiopulmonary complications of nasal obstruction.

Abstract
In E.N.T clinical practice, patients with nasal obstruction due to deviated nasal septum is a common presentation. Nasal airway obstruction is a common cause of upper airway obstruction further leading to obstructive and hypoxic manifestations. Mean platelet volume (MPV) levels increase in hypoxic conditions. MPV is one of the platelet activation index which reflects the platelet production rate. Present prospective study conducted in the department of Otorhinolaryngology and Head and Neck surgery, Gandhi Medical College and Hamidia Hospital, Bhopal, on 63 patients with the clinical evidence of DNS and 63 healthy age matched subjects as control group, aimed to evaluate the relationship between MPV levels and nasal obstruction due to deviated nasal septum (DNS). The diagnosis of patients with DNS was based on anterior rhinoscopy and endoscopic nasal examination. Blood samples were collected before surgical correction. In present study, the authors found that there is preponderance of DNS in the age group of 25-45 years being the most active age group, males having the higher incidence. Majority of cases of DNS being left sided and of obstructed type. MPV were significantly higher in patients with DNS than the control group. Among the cases MPV being higher in females and in the impacted type of DNS. Present study reemphasized the concept that MPV is increased in chronic nasal obstruction due to DNS and this increase is in accordance with the severity of DNS.

Abstract
OBJECTIVE Adenoid hypertrophy (AH) is a common etiology of chronic upper airway obstruction. Upper respiratory tract obstruction may cause chronic alveolar hypoventilation and pulmonary vasoconstriction. In one previous study in patients with obstructive sleep apnea (OSA), it has been claimed that mean platelet volume (MPV), an indicator of platelet activation is increased and that MPV has an important role in the pathophysiology of cardiovascular diseases. We investigated in our study if MPV can be used as an indicator of obstruction due to adenoid hypertrophy. METHODS Our study includes 61 children that underwent adenoidectomy with a mean age of 7.12 (± 2.373). White blood cell, platelet count, MPV, platelet crit and platelet distribution width levels were measured before and 3 months after adenoidectomy. Children's symptoms for upper airway obstruction (UAO) (presence of snoring, mouth breathing or difficulty in breathing during sleep, obstructive breathing or apnea during sleep) were questioned in the preoperative and postoperative period by a standardized questionnaire. RESULTS There was no significant difference between preoperative and postoperative mean values of MPV, hemoglobin, platelet count (p > 0.05). White blood cell levels were significantly higher in the preoperative period values compared with postoperative period values (p < 0.05). Preoperative UAO scores were significantly higher than the postoperative UAO scores. After stratification of the degree of obstruction (as mild, moderate and severe) there was no significant difference in between groups in terms of MPV values. CONCLUSION There was no significant relation between MPV levels and obstructive adenoid hypertrophy.
