© 2022 Elsevier Inc.Objective: This study aims to compare the changes in the nasal airway volume and nasal airflow using acoustic rhinometry (AR), rhinomanometry (RMN), and dental volumetric tomography (DVT) after surgically assisted rapid maxillary expansion (SARME). Study Design: Our study consists of 13 adults, 3 male and 10 female patients, aged between 15 and 26, with completed skeletal development. In our study, DVT imaging was obtained twice, preoperation and 3 months after expansion. AR and RMN measurements were recorded, and Visual Analog Score (VAS) and Nasal Obstruction Symptom Evaluation (NOSE) Scale surveys were scored at preoperation and 3 months after expansion. Nasopharyngeal-oropharyngeal airway volume and areas were calculated using the Romexis 3.8.3.R (Planmeca, Helsinki, Finland) and Nemotec V2019 (Madrid, Spain) software programs. IBM SPSS Statistics 22 (SPSS IBM, Armonk, New York) was used for statistical analysis. Results: Comparing the preoperation and postexpansion measurements by both software programs revealed a statistically significant increase in the nasopharyngeal airway volume. No statistically significant change was observed in the oropharyngeal airway volume. Furthermore, we found a statistically significant increase in VAS but a significant decrease in NOSE. Conclusion: According to our findings, nasal airway volume increased after SARME, and although there was no significant change in nasal resistance, patients’ quality of life increased significantly.

Nasal chondromesenchymal hamartoma (NCMH) is an extremely rare benign tumour of the nasal cavity predominantly described in infants. We report a case involving a 48-year-old woman who had been diagnosed with NCMH a year earlier and now re-presented with a short history of progressive nasal blockage, recurrent epistaxis and orbital apex syndrome. Histopathology was suggestive of malignant transformation into sinonasal sarcoma. However, following multidisciplinary team (MDT) discussions, including second and third opinions from external departments, the histological diagnosis was revised to ‘NCMH with bizarre stromal cells’. Despite this, the lesion demonstrated malignant features of rapid, invasive growth and was treated with palliative radiotherapy. The patient later developed radiological evidence of lung and liver metastases with subsequent pulmonary emboli. Shortly after this, she passed away. This case is unique in its diagnostic challenge, with ambiguous histopathological findings, and highlights the importance of an MDT approach when managing complex sinonasal tumours.

Different techniques exist to provide tip support in rhinoplasty. There is little evidence to provide a consensus on the most effective choice.Evaluating columellar strut graft (CSG) and septal extension grafts (SEG) for their influence on airway function, patient satisfaction and tip support.A retrospective cohort study was undertaken on 165 adult patients who underwent open rhinoplasty with either a CSG or SEG, from February 2012 to August 2019 in a single tertiary facial-plastic practice in Sydney, Australia. Operations were for both cosmetic and functional indications, and both primary and revision cases were assessed. Airway testing and patient-reported outcomes (PROMs) were performed preoperatively and at least 6 months following the procedure. Photographic tip analysis was taken from approximately 4 and 12-month postoperative photographs.Nasal peak inspiratory flow (NPIF) and total nasal airway resistance (NAR) were the primary airway functional outcomes. The primary PROMs analysed were a visual analogue scale (VAS) for nasal obstruction and 13-point Likert scale for global cosmesis, the Nose Outcome Symptom Evaluation (NOSE), and the nasal obstruction score. Tip support was determined by the nasolabial angle (NLA) and Simon's ratio as assessed by Rhinobase developed by Apaydin et al. on lateral Frankfort plane photographs. Data normalised as an improvement over preoperative baseline, accounting for individual variability.A total of 165 patients was assessed (35.2 ± 12.9 yrs, 72% female), 100 (61%) of which received SEG. There were similar nasal airway assessments between CSG and SEG groups, with ΔNPIF (20.0 ± 42.1 L/min v 19.9 ± 44.9 L/min, p = 0.983) and Δ "obstructed" NAR (-1.13 ± 1.90 v -1.02 ± 4.33 Pa/cm3/s, p = 0.849). Amongst PROMs, a greater cosmetic outcome was seen in the SEG group (7.20 ± 2.97 v 5.69 ± 3.45, p 0.01) with all other assessments similar between CSG and SEG techniques. Photographic analysis of tip projection showed reduced NLA distortion in the SEG.While greater patient-perceived cosmesis was seen in patients with a SEG, there were similar airflow and patient-reported nasal function between groups. Photographic analysis of tip projection showed SEG patients additionally benefited from less NLA distortion and greater tip maintenance.

Introduction Obstructive sleep apnea syndrome is a high-prevalence disorder found in the population. Studies have shown a possible association between nasal obstruction and obstructive sleep apnea syndrome, but the existence of a association between the degree of nasal obstruction and obstructive sleep apnea syndrome severity has not yet been proven. Objective To evaluate the internal nasal dimensions of adults with primary snoring and obstructive sleep apnea syndrome by acoustic rhinometry and to correlate the findings with obstructive sleep apnea severity. Methods Twenty-one male Caucasian subjects with complaints of snoring and/or respiratory pauses during sleep, aged between 18 and 60 years of age, were evaluated. After clinical evaluation, otorhinolaryngological examination and flexible nasopharyngolaryngoscopy, all patients underwent type III polysomnography. The participants were divided into two groups according to symptom severity: group 1, primary snoring and/or mild obstructive sleep apnea syndrome(n = 9) and group 2, moderate/severe obstructive sleep apnea syndrome (n = 12). Internal nasal dimensions were measured by acoustic rhinometry, analyzing minimum cross sectional area (CSA) and three nasal segment volumes. Results The respiratory event index corresponded to 8.1 ± 4.0 in group 1 and 47.5 ± 19.1 in group 2. In group 1, the cross-sectional areas values, in cm2, corresponded to: CSA 1 = 1.1 ± 0.4; CSA 2 = 2.1 ± 0.9; CSA 3 = 3.5 ± 1.8 and, in group 2: CSA 1 = 1.2 ± 0.3, CSA 2 = 2.0 ± 0.5; CSA 3 = 2.8 ± 0.7. In group 1, volumes (V), in cm3, corresponded to: V1 = 3.5 ± 1.0; V2 = 9.3 ± 5.0; V3 = 40.2 ± 21.5 and in group 2 a: V1 = 3.6 ± 0.5; V2 = 7.6 ± 1.5; V3 = 31.5 ± 6.7. Cross-sectional area and volume did not differ between groups. Conclusion There were no significant differences in the cross-sectional areas and nasal volumes between individuals with primary snoring-mild obstructive sleep apnea syndrome and moderate-severe obstructive sleep apnea syndrome. Differently to the raised hypothesis, our results suggest that there is no association between internal nasal dimensions and severity of obstructive sleep apnea syndrome. Resumo Introdução A síndrome da apneia obstrutiva do sono é uma desordem de elevada prevalência na população. Estudos constataram possível associação entre obstrução nasal e síndrome da apneia obstrutiva do sono, porém a existência de uma relação entre a intensidade da obstrução nasal e a gravidade da síndrome da apneia obstrutiva do sono ainda não foi comprovada. Objetivo Avaliar as dimensões internas nasais de adultos com ronco primário e síndrome da apneia obstrutiva do sono por meio de rinometria acústica e correlacionar os achados com a gravidade da síndrome da apneia obstrutiva do sono. Método Foram avaliados 21 indivíduos com queixas de ronco e/ou pausas respiratórias durante o sono, gênero masculino, entre 18 e 60 anos, brancos. Após avaliação clínica, exame físico otorrinolaringológico e nasofaringolaringoscopia flexível, todos foram submetidos à polissonografia tipo III. Os participantes foram divididos em dois grupos de acordo com a gravidade dos sintomas: grupo 1, ronco primário e/ou síndrome da apneia obstrutiva do sono leve (n = 9) e grupo 2, síndrome da apneia obstrutiva do sono moderada/grave (n = 12). Dimensões internas nasais foram aferidas por rinometria acústica, foram consideradas para análise as áreas de secção transversa mínima e os volumes de três diferentes segmentos nasais. Resultados O índice de eventos respiratórios correspondeu a 8,1 ± 4,0 no grupo 1 e 47,5 ± 19,1 no grupo 2. No grupo 1, os valores de área de secção transversa, em cm2, corresponderam a: área de secção transversa 1 = 1,1 ± 0,4; área de secção transversa 2 = 2,1 ± 0,9; área de secção transversa 3 = 3,5 ± 1,8. No grupo 2: área de secção transversa 1 = 1,2 ± 0,3, área de secção transversa 2 = 2,0 ± 0,5; áre de secção transversa 3 = 2,8 ± 0,7. No grupo 1 os valores do volume, em cm3, corresponderam a: volume 1 = 3,5 ± 1,0; volume 2 = 9,3 ± 5,0; volume 3 = 40,2 ± 21,5 e no grupo 2 a: volume 1 = 3,6 ± 0,5; V2 = 7,6 ± 1,5; volume 3 = 31,5 ± 6,7. Os valores de área de secção transversa e volume não diferiram entre os grupos. Conclusão Não foram demonstradas diferenças significantes quanto às áreas seccionais transversas e os volumes nasais entre indivíduos com ronco primário e síndrome da apneia obstrutiva do sono leve e síndrome da apneia obstrutiva do sono moderada-grave. Contrariamente à hipótese levantada, os resultados sugerem não existir relação entre as dimensões internas nasais e o nível de gravidade da síndrome da apneia obstrutiva do sono.

The aim of this study was to investigate the ability of Peak Nasal Inspiratory Flow (PNIF) and Peak Nasal Expiratory Flow (PNEF) measures to predict symptoms of nasal obstruction.This is a cross-sectional study, carried out in 131 individuals (64 with symptomatic allergic rhinitis and 67 asymptomatic) aged between 16 and 50 years.PNIF and PNEF were higher among non-rhinitis. In the curve analysis (receiver operating characteristic), a value of 115 was found for PNIF with a sensitivity of 98.4% and specificity of 87.5% (AUC = 0.99, p0.001) and 165 in PNEF with a sensitivity of 65.7% and specificity of 85.1% (AUC = 0.92, p0.001).PNIF and PNEF values were lower in patients with AR compared to asymptomatic cases. Our findings present reference values of PNIF and PNEF in the evaluation of nasal obstruction symptoms and reinforce the importance to complement more refined assessment of patients' symptoms. PNEF can be a valuable tool in screening patients and to complement PNIF measurement.Accuratezza del flusso nasale di picco nella determinazione dell’ostruzione respiratoria nasale nella rinite allergica.Lo scopo di questo studio è indagare la capacità delle misure del flusso di picco inspiratorio nasale (PNIF) e del flusso di picco espiratorio nasale (PNEF) nell’ostruzione respiratoria nasale.Si tratta di uno studio trasversale, condotto su 131 soggetti (64 con rinite allergica sintomatica e 67 asintomatici) di età compresa tra 16 e 50 anni.PNIF e PNEF erano più alti nei pazienti senza rinite. Nell’analisi, il valore di PNIF è risultato essere 115, con una sensibilità del 98,4% e una specificità dell’87,5% (AUC = 0,99, p0,001) e mentre il valore di PNEF è risultato essere 165, con una sensibilità del 65,7% e una specificità di 85,1% (AUC = 0,92, p0,001).I valori di PNIF e PNEF erano inferiori nei pazienti con rinite allergica rispetto agli asintomatici. I nostri risultati mostrano i valori di riferimento delle misure PNIF e PNEF nella valutazione dei sintomi di ostruzione nasale e rafforzano l’importanza di integrare tali dati con la valutazione sintomatologica dei pazienti. La misurazione del PNEF e PNIF, può essere uno strumento prezioso per lo screening dei pazienti con ostruzione nasale.

Objective: Several methods have been reported to correct caudal deviation of the nasal septum, including open septorhinoplasty (OSR) and septoplasty with Killian incision (KI). In general, OSR is applied instead of KI for caudal deviation. However, there is little objective evidence own on the effects of OSR and KI for caudal deviation. In this study, we compared surgical outcomes between OSR and KI by quantifying nasal septum deviation using two simple and objective parameters on routine paranasal sinus CT scans. Methods: We retrospectively analyzed 18 patients who underwent OSR and 11 patients who underwent septoplasty with KI between April 2006 and October 2019. Caudal deviation was defined on the basis of the "Anterior-posterior Position of the most deviated point of the nasal septum (AP)," which was measured on computerized tomography. The deformation rate (DR) of the nasal septum was also calculated. Nasal airway resistance and visual analogue scale (VAS) score for nasal obstruction were examined. Results: The AP was significantly correlated with the VAS score (r =-0.58, p = 0.017). The DR in patients with caudal septal deviation was significantly decreased by OSR (0.14 +/- 0.06 to 0.03 +/- 0.03, p = 0.004), but not by KI (0.09 +/- 0.08 to 0.04 +/- 0.03, p = 0.25). OSR also improved nasal airway resistance (1.10 +/- 0.44 to 0.42 +/- 0.15, p = 0.02), and the VAS score (79.11 +/- 14.74 to 5.78 +/- 7.89, p = 0.004). Conclusion: Nasal obstruction is more severe in patients with the caudal deviation. OSR corrects caudal deviation of the nasal septum more effectively than does KI. The AP could be useful for the evaluation of the deviation of the nasal septum and help in selecting the appropriate septoplastic technique .

Background: The use of virtual noses to predict the outcome of surgery is of increasing interests, particularly, as detailed and objective pre- and postoperative assessments of nasal airway obstruction (NAO) are difficult to perform. The objective of this article is to validate predictions using virtual noses against their experimentally measured counterpart in rigid 3D-printed models. Methods: Virtual nose models, with and without NAO, were reconstructed from patients' cone beam computed tomography scans, and used to evaluate airflow characteristics through computational fluid dynamics simulations. Prototypes of the reconstructed models were 3D printed and instrumented experimentally for pressure measurements. Results: Correlation between the numerical predictions and experimental measurements was shown. Analysis of the flow field indicated that the NAO in the nasal valve increases significantly the wall pressure, shear stress, and incremental nasal resistance behind the obstruction. Conclusions: Airflow predictions in static virtual noses correlate well with detailed experimental measurements on 3D-printed replicas of patient airways.

Introduction: The purpose of the present study was to assess nasal mucociliary clearance (NMC) and sinonasal symptoms of healthcare professionals wearing filtering facepiece-3 (FFP3) respirators. Methods: This prospective cross-sectional study was conducted at a large tertiary care academic center. Thirty-four healthcare professionals working at a coronavirus disease-19 patient care unit were included in the study. Visual analog scale (VAS) scores of sinonasal symptoms (nasal discharge, postnasal discharge, nasal blockage, hyposmia, facial pain/pressure, facial fullness, headache, fatigue, halitosis, cough) and the NMC times of the participants were assessed immediately before wearing FFP3 respirators and after 4 h of work with FFP3 respirators. Results: The mean age of the participants was 28.82 ± 4.95 (range, 26–31) years. Twenty participants were female and 14 were male. After wearing the FFP3 respirators for 4 h, a statistically significant increase was observed in total VAS scores for all sinonasal symptoms and NMC times (p < 0.001). When the VAS score of each sinonasal symptom was evaluated separately, a statistically significant increase was found for VAS scores of nasal discharge, postnasal discharge, nasal blockage, hyposmia, facial pain/pressure, and facial fullness (p < 0.05). Conclusion: The present study shows that nasal mucosal functions might be affected significantly after 4 h of using FFP3 respirators. The long-term effects and clinical significance of these short-term changes should be investigated on healthcare professionals in further studies.

Background Insufficient support of the nasal mid-vault during rhinoplasty can cause significant complications. Accordingly, surgeons have recently paid much more attention to the preservation of nasal patency. The spreader graft is the gold standard technique for the reconstruction of nasal mid-vault. Objectives The objective of this study was to compare the spreader graft and spreader flap in terms of aesthetic and functional outcomes. Methods An inclusive search was performed with PubMed/Medline, Google Scholar, and Cochrane Library databases up to April 2021. Multiple aesthetic and functional factors, including dorsal aesthetic lines restoration, satisfaction rate, internal nasal valve angle improvement, nasal obstruction symptom evaluation scale, and active anterior rhinomanometry were evaluated. Also, a meta-analysis was performed on the included articles that provided adequate data for mentioned factors. Results After excluding papers that did not conform with the selection criteria, 10 articles with a total sample size of 567 cases with a mean age of 27.7 years (range, 18-65 years) were finally included. Analysis of the data revealed no statistically significant difference between the spreader graft and spreader flap techniques in terms of dorsal aesthetic lines restoration, internal nasal valve angle improvement, nasal obstruction symptom evaluation scale, and anterior rhinomanometry. Conclusions However, in terms of satisfaction rate, the analyzes indicated that spreader graft has significantly superior aesthetic outcomes. Generally, in case of appropriately selected patients, there is no statistically significant difference between spreader graft and spreader flap techniques in terms of aesthetic and functional outcomes.

ObjectiveThis study investigated whether inferior turbinate reduction combined with septoplasty improves patients’ outcomes, as assessed by objective and subjective methods.MethodsA single-centre, parallel-group, randomised, open-label trial was conducted at a tertiary hospital ENT clinic. Patients who underwent septoplasty were divided into two groups: group A underwent septoplasty with radiofrequency ablation; group B underwent only septoplasty. All patients were assessed before and three months after surgery using acoustic rhinometry and peak nasal inspiratory flow measurements, as well as Nasal Obstruction Symptom Evaluation scale and Sino-Nasal Outcome Test-22 scores.ResultsSeventy-four patients completed the study (36 in group A and 38 in group B). The patients in both groups showed significant improvements in acoustic rhinometry and peak nasal inspiratory flow measurements and in Nasal Obstruction Symptom Evaluation scale and Sino-Nasal Outcome Test-22 scores after the surgery (p < 0.05). However, the differences between the groups were not significant (p > 0.05).ConclusionInferior turbinate ablation combined with septoplasty does not provide any more benefit to the objective and subjective outcomes of patients than septoplasty alone.

Background Nasal obstruction is a common problem, with significant impact on quality of life. Accurate diagnosis may be challenging because of the complex and dynamic nature of the involved anatomy. Computational fluid dynamics modeling has the ability to identify specific anatomical defects, allowing for a targeted surgical approach. The goal of the current study is to better understand nasal obstruction as it pertains to disease-specific quality of life by way of a novel computational fluid dynamics model of nasal airflow. Methods Fifty-three patients with nasal obstruction underwent computational fluid dynamics modeling based on computed tomographic imaging. Nasal resistance was compared to demographic data and baseline subjective nasal patency based on Nasal Obstructive Symptom Evaluation scores. Results Mean Nasal Obstructive Symptom Evaluation score among all patients was 72.6. Nasal Obstructive Symptom Evaluation score demonstrated a significant association with nasal resistance in patients with static obstruction (p = 0.03). There was a positive correlation between Nasal Obstructive Symptom Evaluation score and nasal resistance in patients with static bilateral nasal obstruction (R2 = 0.32) and poor correlation in patients with dynamic bilateral obstruction caused by nasal valve collapse (R2 = 0.02). Patients with moderate and severe bilateral symptoms had significantly higher nasal resistance compared to those with unilateral symptoms (p = 0.048). Conclusions Nasal obstruction is a multifactorial condition in most patients. This study shows correlation between simulated nasal resistance and Nasal Obstructive Symptom Evaluation score in a select group of patients. There is currently no standardized diagnostic algorithm or gold standard objective measure of nasal airflow; however, computational fluid dynamics may better inform treatment planning and surgical techniques on an individual basis.

Introduction: Nasal septal deviation may contribute to a wide range of symptoms including nasal obstruction, headache, increased secretion, crusting, mucosal damage, and loss of taste and smell. Excessive increase in the respiratory resistance, as seen in nasal septal deviation, results in reduced lung ventilation, thereby potentially leading to hypoxia, hypercapnia, pulmonary vasoconstriction. The deformities in the nasal cavity can be associated with major respiratory and circulatory system diseases. Objective: To investigate cardiovascular effects of septoplasty by comparing pre- and postoperative transthoracic echocardiography findings in nasal septal deviation patients undergoing septoplasty. Methods: The prospective study included 35 patients with moderate and severe nasal septal deviation (mean age, 23.91 ± 7.01) who underwent septoplasty. The Turkish version of the nasal obstruction symptom evaluation, NOSE questionnaire, was administered to each participant both pre- and postoperatively in order to assess their views on the severity of nasal septal deviation, the effect of nasal obstruction, and the effectiveness of surgical outcomes. A comprehensive transthoracic echocardiography examination was performed both preoperatively and at three months postoperatively for each patient and the findings were compared among patients. Results: Mean preoperative NOSE score was 17.34 ± 1.62 and the mean postoperative score was 2.62 ± 1.68 (p = 0.00). Mean preoperative systolic pulmonary artery pressure value was 22.34 ± 4.31 mmHg and postoperative value was 18.90 ± 3.77 mmHg (p = 0.00). Mean E/e’ ratio was 5.33 ± 1.00 preoperatively and was 5.01 ± 0.90 postoperatively (p = 0.01). The NOSE scores, systolic pulmonary artery pressure values, and the E/e’ ratios decreased significantly after septoplasty (p 0.05). Conclusion: The decrease in NOSE scores following septoplasty indicated that the satisfaction levels of the patients were increased. Upper airway obstruction secondary to nasal septal deviation may be a cardiovascular risk factor and may affect transthoracic echocardiography measurements. Moreover, the significant decrease in the systolic pulmonary artery pressure value and E/e’s ratio following septoplasty indicated that negative echocardiographic findings may be prevented by this surgery. Resumo Introdução: O desvio do septal nasal pode ter uma ampla gama de manifestações, inclusive obstrução nasal, cefaleia, aumento da secreção, crostas, dano à mucosa e perda do paladar do olfato. O aumento excessivo da resistência respiratória, como visto no desvio do septal nasal, resulta em ventilação pulmonar reduzida, leva a hipóxia, hipercapnia e vasoconstrição pulmonar. As deformidades da cavidade nasal podem estar associadas a doenças importantes do aparelho respiratório e circulatório. Objetivo: Investigar os efeitos cardiovasculares da septoplastia, comparar os achados prée pós-operatórios da ecocardiografia transtorácica de pacientes com desvio do septal nasal submetidos à septoplastia. Método: O estudo prospectivo incluiu 35 pacientes com desvio do septal nasal moderado e grave (média de idade, 23,91 ± 7,01) submetidos à septoplastia. A versão em turco do questionário Nasal Obstruction Symptom Evaluation (NOSE) foi administrada a cada participante no pré e pós-operatório para avaliar suas opiniões sobre a gravidade do desvio do septal nasal, o efeito da obstrução nasal e a eficácia dos resultados cirúrgicos. Um exame abrangente da ecocardiografia transtorácica foi feito no pré-operatório e após três meses de pós-operatório em cada paciente e os resultados foram comparados entre os pacientes. Resultados: O escore médio do NOSE pré-operatório foi de 17,34 ± 1,62 e o escore pós-operatório médio foi de 2,62 ± 1,68 (p = 0,00). O valor médio da pressão sistólica arterial pulmonar pré-operatória foi de 22,34 ± 4,31 mmHg e o valor pós-operatório foi de 18,90 ± 3,77 mmHg (p = 0,00). A relação E/e’ média foi de 5,33 ± 1,00 no pré-operatório e 5,01 ± 0,90 no pós-operatório (p = 0,01). Os escores NOSE, os valores de pressão sistólica arterial pulmonar e as relações E/e’ diminuíram significativamente após a septoplastia (p 0,05). Conclusão: A diminuição dos escores NOSE após a septoplastia indicou que os níveis de satisfação dos pacientes aumentaram. A obstrução das vias aéreas superiores secundária ao desvio do septal nasal pode ser um fator de risco cardiovascular e pode afetar as medidas da ecocardiografia transtorácica. Além disso, a diminuição significativa no valor de pressão sistólica arterial pulmonar e na relação E/e’ após a septoplastia indicou que os achados ecocardiográficos negativos podem ser evitados por essa cirurgia.

Septoplasty is one of the most common otolaryngological surgical procedures. The causes of persistent septal deviation after primary septoplasty vary. The purpose of this study was to identify factors associated with failure of primary septoplasty, operative techniques that correct residual septal deviation, and surgical outcomes. Seventy-four adults who underwent revision septoplasty to treat persistent septal deviations were enrolled. The level of hospital in which primary septoplasty was performed, type of septal deviation, septal portion exhibiting persistent deviation, and techniques used to correct the deviation were evaluated. Outcomes were measured subjectively using a visual analog scale (VAS), and objectively using acoustic rhinometry. The first septoplasties were usually performed in primary and secondary hospitals. C-shaped deviations were more common than S-shaped ones in both the anteroposterior and cephalocaudal dimensions. The most common region of persistent septal deviation was the caudal septum (44.6%), followed by multiple sites (20.3%). The corrective techniques included excision of the remnant deviated portion (70.3%), septal cartilage traction suturing (27.0%), spreader grafting (13.5%), and cross-suturing (6.8%). The VAS score improved significantly 6 months after surgery. The minimal cross-sectional area and nasal cavity volume of the convex side increased significantly after revision septoplasty. Patients who underwent septoplasty in primary and secondary hospitals were more likely to require revision septoplasty. The caudal septum was the most common site of persistent septal deviation. Careful preoperative evaluation of the caudal septal deviation and selection of an appropriate surgical technique may reduce the need for revision septoplasty.

The aim of this study was to investigate the relationship between nasal airway obstruction (NAO) and symptoms of orofacial pain, including temporomandibular joint pathology and primary headaches. This study was a retrospective analysis of consecutive patients seeking care for chronic orofacial pain at 14 North American treatment centers. The standardized evaluation protocol followed for all patients included cone beam computed tomography (CBCT), a comprehensive clinical examination, and a thorough review of the patient's subjective complaints and health history, including pain and sleep pathology. The primary conditions of interest in this study were the following 5 types of NAO: nasal valve compromise (NVC), deviated septum, septal swell body, concha bullosa, and inferior turbinate soft tissue hypertrophy. Descriptive statistics and regression analysis were performed to determine comorbidities between orofacial pain symptoms and NAO observed on CBCT images. The study population consisted of 1393 patients, 253 men (18.2%) and 1140 women (81.8%). The mean age of the patients was 43.3 (SD 18.1) years. NVC was the most prevalent type of NAO found in the study population (n = 1006; 72.2%). NVC showed a statistically significant comorbidity with capsulitis (odds ratio, 3.73) as well as facial and cervical myositis (odds ratio, 6.97). To the author's knowledge, this is first time that these comorbidities have been identified. NAO had a high comorbidity with orofacial pain. Specifically, NVC was a major contributor to NAO. An understanding of the mechanisms of orofacial pain as well as the effects of improper (mouth) breathing, adaptive forward head posture, muscular fatigue, parafunction, and temporomandibular joint pathology will help the clinician to evaluate the role a patient's nose may be playing in orofacial pain.

BACKGROUND Hemangiomas are commonly located in the head and neck and rarely in the paranasal sinuses. These are benign vascular lesions, but with an increased risk of bleeding. The surgical approach must have detailed prior planning, given the increased risk of intraoperative bleeding. We herein describe the case of a 32-year-old male patient with recurrent epistaxis, nasal obstruction, and facial deformity due to a giant cavernous hemangioma successfully treated by endoscopic sinus surgery. CASE REPORT A 32-year-old man had nasal obstruction and intermittent epistaxis for 2 months. Physical examination also revealed facial deformity with enlargement of the nasal base and bulging in the maxillary region on the right. A soft and friable lesion occupying the entire right nasal cavity without bone erosion was observed on computed tomography (CT scan). Before surgery, the patient underwent angiographic evaluation, with evidence of main irrigation of the lesion by the right maxillary artery, which was then embolized. The patient underwent endoscopic nasal surgery. He maintained postoperative follow-up for 18 months, without recurrence of the lesion. Anatomopathological examination confirmed a cavernous hemangioma. CONCLUSIONS Cavernous hemangioma is a benign lesion of the paranasal sinuses. Due to non-specific clinical and radiological findings, its preoperative diagnosis is always challenging. The high index of suspicion of the malignancy should only be discarded after complete anatomopathological evaluation. A correct diagnosis is essential to avoid facial anatomical remodeling while excluding the diagnosis of other malignant lesions.

Paediatric patients with nasal obstruction are frequently encountered in general practice. The differential diagnosis is distinct from that of adult nasal obstruction and necessitates more judicious use of radiological and invasive investigations. Most cases of nasal obstruction in children result from benign disease, although there is a significant quality of life impact that must be addressed with prompt diagnosis and symptomatic management.The aim of this article is to outline the workup and management of paediatric nasal obstruction in primary care and suggest where referral to a relevant specialist is warranted.Although the differential for paediatric nasal obstruction is broad, a thorough history and physical examination yields the diagnosis in most cases. Diagnoses not to be missed include nasal foreign body, lesions suspicious for neoplasia and intracranial complications of severe rhinosinusitis. Further investigation and ear, nose and throat referral should be considered when there are surgical targets for nasal obstruction, red flag signs or symptoms or failure of conservative therapy.

Introduction: Compensatory inferior turbinate hypertrophy is a common accompanying manifestation in patients with nasal obstruction due to deviated nasal septum (DNS). The grounds for inferior turbinate reduction (ITR) in this population are still not well established. This systematic review and meta-analysis aimed to evaluate the efficacy and safety of septoplasty with ITR versus septoplasty alone. Methods: Computerised search in Medline, Embase, and CENTRAL was performed. Eligible for inclusion were randomised controlled trials (RCTs) comparing septoplasty to septoplasty with unilateral, contralateral, ITR in adults with DNS. Primary outcomes were health-related quality of life and nasal patency. The secondary outcome was the occurrence of adverse events. Standardised mean differences (SMD) and odds ratios (OR) with 95% confidence intervals were calculated. Results: Twelve RCTs that enrolled 775 participants were found eligible. Data were reported at follow-up periods ranging from 1 month to 48 months. The pooled effect estimate showed a statistically significant improvement with unilateral, contralateral, ITR in Nasal Obstruction Symptom Evaluation scale (NOSE) scores. The rate of adverse events was significantly higher with ITR. Conclusions: Unilateral reduction of the hypertrophied contralateral inferior turbinate during septoplasty resulted in better subjective relief of nasal obstruction in adults with DNS than septoplasty alone. However, caution is warranted since only few well-designed RCTs were identified.

Introduction: Quality of life has been an increasingly reference measure in whole health impact of diseases and in septorhinoplasty evaluation as well. It is known that the decision for this elective surgical procedure requires the subjective perception of patients’ complaints about their own health and life stage in association with the surgeon’s aesthetic and functional perspective of each case. Objective: To define the quality of life of candidates for septorhinoplasty using the World Health Organization quality of life questionnaire, WHOQOL-Brief, and the prevalence of other independent variables for this population. Methods: A cross-sectional study using a sample of candidates for septorhinoplasty was performed. All patients responded to the WHOQOL-Brief during the pre-operative period. A normative population quality of life study was the reference for the sample size and means. Results: A total of 302 patients were included among the 322 eligible patients. Twenty patients did not complete the questionnaire correctly and were excluded from the study. The sample consisted of patients aged between 15 and 78 years (34.7±14 years): the most majority were Caucasian and female. Among this group, 88.1% declared symptoms of nasal obstruction and 77.4% complained of sleeping problems. It was seen that 10.9% patients chose the surgery primarily for aesthetic improvement; 37.1% chose it mainly because of functional symptoms and 52% chose it for both functional and aesthetic reasons. The physical health domain’s mean was 62.2 ± 17), which is a higher mean compared to the references’ standard one (Μ = 58.9± 10.5, p = 0.002). The social relationship domain mean was 70.8±18.1; that is a lower mean then general population’s one (Μ = 76.2± 18.8, p < 0.001). The psychological and the environment domain means revealed no difference when comparing the sample to the norm (μ = 65.3 ±15.1 vs. μ = 65.9 ±10.8, p = 0.530 and μ = 60.3 ±13.1 vs. μ = 59.9 ± 14.9, p = 0.667). Conclusion: The WHOQOL-Brief questionnaire proved an accurate instrument to cross-check different populations in quality of life outcomes. The study provides good evidence of lower quality of life in social relations domain and high prevalence of nasal obstruction and sleeping symptoms in candidates for septorhinoplasty. This study contributes to recent literature with relevant data supporting a more integrative evaluation in this population in the preoperative period. The results may also encourage a multidisciplinary approach for chronic symptoms when associated with nasal obstruction, sleep disorders and aesthetic complaints.

Purpose Active anterior rhinomanometry (AAR) and computed tomography (CT) are standardized methods for the evaluation of nasal obstruction. Recent attempts to correlate AAR with CT-based computational fluid dynamics (CFD) have been controversial. We aimed to investigate this correlation and agreement based on an in-house developed procedure. Methods In a pilot study, we retrospectively examined five subjects scheduled for septoplasty, along with preoperative digital volume tomography and AAR. The simulation was performed with Sailfish CFD, a lattice Boltzmann code. We examined the correlation and agreement of pressure derived from AAR (RhinoPress) and simulation (SimPress) and these of resistance during inspiration by 150 Pa pressure drop derived from AAR (RhinoRes150) and simulation (SimRes150). For investigation of correlation between pressures and between resistances, a univariate analysis of variance and a Pearson’s correlation were performed, respectively. For investigation of agreement, the Bland–Altman method was used. Results The correlation coefficient between RhinoPress and SimPress was r = 0.93 (p r = 0.65; p = 0.041). Conclusion The simulation of rhinomanometry pressure by CT-based CFD seems more feasible with the lattice Boltzmann code in the less obstructed nasal side. In the more obstructed nasal side, error rates of up to 100% were encountered. Our results imply that the pressure and resistance derived from CT-based CFD and AAR were similar, yet not same.

Pyriform aperture enlargement or "pyriplasty" is an uncommonly used procedure for internal nasal valve obstruction in adults besides functional rhinoplasty, inferior turbinate reduction, and septoplasty. A systematic review of the literature was performed to analyze current surgical techniques, their suggested indications, and their related outcome in terms of success and complications.The search was performed on PubMed, EMBASE, SCOPUS, and Cochrane databases.The systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies on congenital, traumatic, tumoral, or infectious internal nasal valve obstruction were excluded.Eight articles were finally included. Three types of pyriplasty have been described according to the level of bone resection: low-level pyriplasty through the sublabial approach, mid-level pyriplasty through endonasal approach, and extended pyriplasty through either approach. Indications included (1) clinically or radiologically narrow pyriform aperture, (2) previously unsuccessful internal nasal valve surgery, (3) lateral nasal wall collapse, and (4) inferior turbinate's head hypertrophy. Subjective improvement of nasal obstruction was reported in these 4 indications. No major complication was encountered.Pyriplasty for nasal obstruction is a simple and safe procedure that could be effective in selected cases. However, level of evidence is currently low, and success rate may vary with indications and pyriplasty techniques. Moreover, there is no clear definition of normal pyriform aperture dimensions to date. Further prospective studies are thereby necessary and should include radiological analysis of pyriform aperture and validated nasal obstruction measurement tools.

Introduction Obstructive sleep apnea is the most common type of sleep apnea, which is caused by complete or partial obstructions of the upper airway. Nasal obstruction is also considered as one of the independent risk factors of obstructive sleep apnea. Objective Patients with obstructive sleep apnea. Methods We enrolled patients with obstructive sleep apnea from June to December 2015 and treated them with intranasal corticosteroid spray for four weeks. Several parameters were obtained before and after the treatment, including Nasal Obstruction Symptom Evaluation scores, Pittsburgh Sleep Quality Index questionnaire and Epworth Sleepiness Scale questionnaire. Results Fifty patients completed questionnaires prior to and following the intranasal fluticasone treatments. The average age was 39.7 ± 15.6 y, with a male to female ratio of 3:2. The post-treatment Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, and Nasal Obstruction Symptom Evaluation scores all indicated a decrease compared to pre-treatment scores, from 10.4 to 8.74, 7.86 to 6.66 and 9.08 to 6.48, respectively. A significant decrease was observed in the Nasal Obstruction Symptom Evaluation ≥10 group in all three categories, but not in the Nasal Obstruction Symptom Evaluation Conclusions Intranasal fluticasone treatment may be useful for patients with nasal obstruction-related obstructive sleep apnea to improve sleep quality and limit daytime dysfunction.

Objectives The aim of this prospective study was to evaluate the effect of modified extracorporeal endonasal septoplasty on nasal tip shape and function in patients with severe caudal septal deviation. Methods The study population comprised of 55 patients undergoing modified extracorporeal endonasal septoplasty, which called marionette septoplasty. To analyse the aesthetic objective outcomes, postoperative photographs were measured for projection index (PI), tip projection (TP), nasolabial angle (NLA), tip deviation angle (TDA), nasofrontal angle (NFA), supratip height (STH), columellar height (CH), at three times (2 weeks, 3, and 6 months after surgery) and were compared with preoperative photographs. Functional and aesthetic outcomes were also evaluated using nasal obstruction symptom evaluation (NOSE) scale and standardized cosmesis and health nasal outcomes survey (SCHNOS). Results Between the pre- and post-operative 6th-month examinations, a significant increase in PI and TP were 7%, and 5% respectively. There was a significant alteration in the NLA and TDA values following the last examination (mean difference ± standard error of mean 9.68 ± 0.9° and 1.5 ± 0.8°, respectively). Moreover, the technique did not make a significant change in the final NFA, STH, and CH, measurements. Following surgery, the NOSE and SCHNOS scores were decreased significantly and the improvement continued over time until the last examination. Conclusion The present study findings suggest that the marionette septoplasty technique is an effective to correct and stabilize severe caudal septal deviations. This technique also can provide tip support and protection with a low incidence of dorsal irregularity.

Importance: Septoplasty is used to correct nasal obstructions caused by a deviated septum. In some patients, septal deviation is also associated with external nasal deformity, which suggests that p...

Background: Predicting symptomatic relief after septoplasty has been difficult. Minimal cross-sectional area (mCSA) measured by acoustic rhinometry and airflow resistance (R) measured by rhinomanometry have been used to select surgical candidates with mixed success. An important assumption is that mCSA and resistance are tightly coupled, but studies have reported weak or no correlation. Recently, we proposed the Bernoulli Obstruction Theory as an explanation, where tight coupling between mCSA and R is only predicted below a critical mCSA (A(crit)). Methods: The nasal airway and septum of 10 healthy subjects were reconstructed from computed tomography scans. Simulated anterior septal deviations of increasing severity were created. Computational fluid dynamics simulations were performed to quantify mCSA, resistance, and flow in the healthy septum model and four simulated septal deviation models for each subject (total of 50 models). Results: A tighter coupling between mCSA and resistance was found below A(crit), estimated to be 0.20 cm(2) (a very severe deviation). Above A(crit), enlarging the mCSA had a smaller effect in patients with narrower cross-sectional area in the postvalve region (CSA(PV)). Conclusions: Two patterns of flow increase are expected with septoplasty. Below A(crit), enlarging mCSA predictably increases flow. Above A(crit), the effect size of increasing mCSA depends on CSA(PV). Unrecognized small CSA(PV) may explain persistent sensation of nasal obstruction after septoplasty. Our data suggest that inferior turbinate reduction ipsilateral to a septal deviation may amplify airflow benefits after septoplasty in patients with a narrow CSA(PV).

Background: The microdebrider technique was introduced in clinical practice to provide a better outcome in nasal obstruction caused by inferior turbinate hypertrophy. We conducted this systematic review to evaluate the effectiveness of this technique, by comparison with the radiofrequency-assisted modality. Methodology: PubMed, Embase and the Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched to retrieve relevant randomised studies published prior to November 2019. Randomised Trials in English that studied the difference between the two techniques among adult patients were eligible for the current review. Data extraction and study inclusion were guided by PRISMA guidelines. The outcome measures were visual analogue scale (VAS, 0-10) for nasal obstruction, anterior active rhinomanometry, and acoustic rhinometry. A meta-analysis was carried out to quantify the difference between the two techni- ques, for each measured outcome. Results: Seven randomised trials were included and quantitatively analysed in this meta-analysis. Our analysis revealed that the microdebrider-assisted technique demonstrated significantly better VAS (0-10) for nasal obstruction scores in early and late posto- perative follow-up. Whilst no difference was noted using the objective measurements (rhinomanometry and acoustic rhinometry) at early follow-up, microdebrider-assisted technique showed superior results in long-term follow-up, as evidenced using anterior active rhinomanometry. Conclusions: The microdebrider-assisted technique results in a better outcome, particularly in long-term follow-up, when compa- red with radiofrequency.

Background: Vitamin D supplementation has been proven to be effective in the treatment of allergic rhinitis (AR). Objective: We conducted the present study to explore the role and efficacy of vitamin D adjuvant therapy for the treatment of inflammation in patients with AR. Methods: Out of 127 patients with potential eligible AR, 60 were randomly assigned into two groups and were finally included in our analysis (n=30 for each intervention). The patients with potential eligible AR were randomly allocated to intervention with desloratadine citrate disodium (DCD, 8.8 mg/day) without and with vitamin D3 nasal drops (1.5х106 IU, once/week) for four weeks. Thirty healthy control subjects were included in our study. We assessed the changes in the serum 25(OH)D, peripheral blood eosinophils, interleukin (IL)-4 levels, and nasal symptoms. Serum 25(OH)D, peripheral blood eosinophils, and IL-4 levels were detected respectively with liquid chromatography-tandem mass spectrometry (LC-MS/MS), a blood detector, and enzyme-linked immunosorbent assay. Results: Our patients who received vitamin D3 adjuvant therapy had a higher serum 25(OH)D level (47.57 ± 2.83 vs. 31.51 ± 2.95 ng/ml, p=0.000) and lower AR symptoms score (2.07 ± 1.89 vs. 3.37 ± 1.50, p=0.005), serum IL-4 (10.38 ± 3.41 vs. 12.79 ± 5.40 pg/ml, p=0.043), and peripheral blood eosinophils (0.34 ± 0.09 vs. 0.41 ± 0.10 109/l, p=0.003) compared with DCD single treatment. The efficacy rates of DCD with and without vitamin D3 in AR were 97% and 84%, respectively. Conclusion: Nasal vitamin D3 combined with DCD could improve the clinical symptoms of AR. Vitamin D3 adjunct therapy showed significant effects on inhibiting inflammation in patients with AR. We concluded that vitamin D3 supplementation could be an effective adjuvant therapy in AR patients.

Deviated nasal septum (DNS) is suggested to be associated with nonspecific inflammation of the nasal mucosa. The authors hypothesized septoplasty may reduce nasal mucosal inflammation, therefore the authors aimed to measure various inflammatory biomarkers in the nasal secretion following septoplasty. Prospectively, 17 patients undergoing elective septoplasty were included. Symptomatic changes after septoplasty were evaluated with Sino-nasal Outcome Test (SNOT-22) and Nasal obstruction symptom evaluation (NOSE) scores. Using acoustic rhinometry, changes of the nasal airway volume were measured. Nasal secretion was collected within 2 weeks and 3 months before and after septoplasty, respectively. The inflammatory biomarker high-mobility group box 1 (HMGB1) and vasoactive intestinal peptide (VIP), and inflammatory cytokines including tumor necrosis factor α (TNF α), interferon γ (IFN-γ), interleukin-4 (IL-4), eotaxin-1, and regulated upon activation, normal T cell expressed and presumably secreted (RANTES) were quantified in the nasal secretion by enzyme-linked immunosorbent assays or multiplex bead array assays. The patients' mean age was 30.5 ± 6.8 (ranging from 19 to 43), consisting of 15 male and 2 female patients. The median SNOT-22 and NOSE scores changed from 54 to 14 and 78 to 15, respectively, both showing a significant decrease. In acoustic rhinometry, nasal cavity volume of convex side significantly increased after septoplasty, whereas significant discrepancy of nasal airway volume between concave and convex sides became insignificant. No significant difference was noted both before and after septoplasty between the concave and convex sides in all seven biomarkers. The HMGB1, RANTES, IL-4, and TNF-α concentrations following septoplasty showed significant decrease in 34 nasal cavities of 17 patients (all p

Primary heterotopic meningiomas are lesions that are not associated with a cranial nerve foramen, vertebral canal, or intracranial structure. The most common histopathological subtype is meningeal epithelioma. In clinical practice, primary heterotopic nasal meningioma occurs relatively rarely, and its most common pathological type is psammomatous meningioma, whereas nasal fibrous meningioma is infrequent. In our case, a 31-year-old male patient was admitted to the hospital with “progressive nasal obstruction on the right side for half a year.” Computed tomography examination of the paranasal sinuses revealed a polyploid mass in the right nasal cavity. The patient underwent surgical resection of the mass under nasal endoscopy. Histopathological examination confirmed that the mass was an ectopic meningioma of the nasal cavity. The patient was regularly followed up for 2 years without recurrence of the tumor. Primary heterotopic fibrous meningioma of the nasal cavity is clinically rare but should be considered as a differential diagnosis for hemangioma of the nasal cavity, inverted papilloma, and nasal polyp. The final diagnosis is based on pathology and immunohistochemistry analysis results.

OBJECTIVES Correcting the caudal septum deviation is one of the most difficult parts of the septoplasty. The aim of the present study was to evaluate the efficiency and usefulness of traction suture method in caudal septum deviations. METHODS Medical records of 35 patients who underwent endonasal septoplasty using traction suture method for caudal septum deviation in August 2017-February 2019 period were studied retrospectively. Preoperative nasal obstruction symptom evaluation (NOSE) scores of the patients were compared with postoperative sixth month NOSE scores. Besides, preoperative nasal examination findings of the patients were compared with the ones in postoperative period. RESULTS Average age of the 35 patients (9 women and 26 men) in the study was 26.3 ± 10.1 years. Postoperative observations revealed that a straight septum was achieved in 31 patients (91.1%). Average pre- and postoperative NOSE scores were 85.1 ± 20.4 and 22.4 ± 4.2, respectively (P

Eosinophilic angiocentric fibrosis (EAF) is a rare and slowly progressive disease, which usually involves the sino-nasal structures and upper respiratory tract. It is a fibroinflammatory lesion with an unclear etiology. Recent literature suggests a relation to rheumatic or immunological disorders. Therefore, immunophenotypic workup is critical when suspected. We report a case of a 32-year-old man complaining of nasal obstruction lasting more than 2 years. Nasal endoscopy and computed tomography showed a deviated septum with bilateral soft tissue swelling. During the septoturbinoplasty, a submucosal mass with severe adhesion was observed beneath the septal flap. The mass was completely removed. Dense stromal fibrosis with eosinophil-rich inflammatory cell infiltration was found on histologic examination and the patient was diagnosed with EAF. In addition, we reviewed the pathologic diagnostic criteria, differential diagnosis, and management of EAF.

Purpose The goal of this study was to develop a complete workflow allowing for conducting computational fluid dynamics (CFD) simulation of airflow through the upper airways based on computed tomography (CT) and cone-beam computed tomography (CBCT) studies of individual adult patients. Methods This study is based on CT images of 16 patients. Image processing and model generation of the human nasal cavity and paranasal sinuses were performed using open-source and freeware software. 3-D Slicer was used primarily for segmentation and new surface model generation. Further processing was done using Autodesk® Meshmixer TM. The governing equations are discretized by means of the finite volume method. Subsequently, the corresponding algebraic equation systems were solved by OpenFOAM software. Results We described the protocol for the preparation of a 3-D model of the nasal cavity and paranasal sinuses and highlighted several problems that the future researcher may encounter. The CFD results were presented based on examples of 3-D models of the patient 1 (norm) and patient 2 (pathological changes). Conclusion The short training time for new user without a prior experience in image segmentation and 3-D mesh editing is an important advantage of this type of research. Both CBCT and CT are useful for model building. However, CBCT may have limitations. The Q criterion in CFD illustrates the considerable complication of the nasal flow and allows for direct evaluation and quantitative comparison of various flows and can be used for the assessment of nasal airflow.

Aims The surgical management of contralateral inferior turbinate hypertrophy in patients with deviated nasal septum is controversial. In this randomised clinical trial, we aimed to investigate the subjective improvement of nasal symptoms postoperatively in patients undergoing septoplasty with or without inferior turbinoplasty. Material and methods One hundred and thirty-seven patients with nasal obstruction, who had unilateral septal deviation and compensatory contralateral inferior turbinate enlargement, were randomised into either septoplasty alone arm (n = 66) or septoplasty combined with turbinoplasty arm (n = 71). Preoperative symptom scores and the subjective perception of the nasal obstruction were compared between two groups of the study using Nasal Obstruction Symptom Evaluation Scale (NOSE) and Visual analog scale (VAS) respectively. The measurements were repeated 6 months after surgery as well as at 1, 2, and 4 years postoperatively. Results With regard to the findings obtained from both scales, both interventions successfully relieved the patients’ complaints of nasal obstruction at almost all postoperative visits when compared with the baseline measurements (P ˂ 0.005 for most comparisons). However, the relief of nasal obstruction was more pronounced in patients undergoing combined intervention at all postoperative visits, except at the 1st follow-up session (P ˂ 0.005). Nasal symptoms of septoplasty alone group began to deteriorate over the period between month 24 and month 48. In contrast, patients undergoing the combined surgery steadily showed symptomatic improvement over the whole period of study. Conclusions A turbinate reduction surgery should be conducted along with septoplasty to achieve better results in cases suffering from deviated nasal septum with concomitant hypertrophied inferior turbinate.

The commonest causes of nasal obstruction are rhinitis and chronic rhinosinusitis, which affect up to 30% and 14% of the adult population, respectively. The global financial burden is huge, estimated at $5 billion for rhinitis and $8.6 billion for chronic rhinosinusitis per annum in the USA. On referral for imaging, computed tomography (CT) is indicated initially when there is a suboptimal response to medical treatment of these mucosal diseases or there are "red flags," such as persistent unilateral obstruction, epistaxis, pain, and orbital or neurological symptoms. A mass visible at rhinoscopy or endoscopy in the nose or nasopharynx and lymphadenopathy are further indications. The anterior (cartilaginous) nose plays a key role in the aetiology of nasal obstruction as it accounts for 50-75% of the total resistance to airflow in the upper airway. It has been ignored in the imaging literature, but extensively evaluated by clinicians using a range of methods, including CT. Oblique reconstructions perpendicular to the parabolic curve of lamellar airflow provide accurate assessment of the anterior nose. A thorough and systematic approach to assessing the nose addresses the discrepancy between imaging and clinical evaluation of structural causes of nasal obstruction, especially septal deviation, reported in the surgical literature. Nasal tumours are a very uncommon cause of nasal obstruction; magnetic resonance imaging is commonly performed to assess their full extent and improve the specificity of diagnosis.

To investigate day, night and 24 h all blood pressure effects of septoplasty by comparing pre- and post-operative 24-h ambulatory blood pressure monitoring (ABPM) values of NSD patients undergoing septoplasty. The prospective study included 20 patients with type 2 and 3 pure NSD (mean age, 23.60 ± 6.51) who underwent septoplasty in our clinic. Nasal obstruction symptom evaluation (NOSE) questionnaire was applied to each participant both pre- and post-operatively to evaluate their views on the severity of NSD and the effectiveness of surgical outcomes. A comprehensive ABPM examination was performed both 2 days before surgery and at three months postoperatively for each patient and the findings were compared among patients. Preoperative NOSE score was 87.75 ± 7.34% and the postoperative score was 12.50 ± 6.58% (p = 0.000). Following septoplasty, 24-h systolic blood pressure (24SBP) declined from 119.4 ± 9.9 mmHg to 112.2 ± 8.0 mmHg (p = 0.000), daytime SBP (DSBP) declined from 125.9 ± 11.0 mmHg to 117.9 ± 8.4 mmHg (p = 0.000), nighttime SBP (NSBP) declined from 112.7 ± 9.5 mmHg to 105.5 ± 7.9 mmHg (p = 0.000), 24-h pulse pressure (24PP) declined from 46.7 ± 10.1 mmHg to 44.0 ± 8.4 mmHg (p = 0.015), and mean daytime PP (DPP) declined from 46.9 ± 9.7 mmHg to 44.6 ± 8.6 mmHg (p = 0.026). The decline in NOSE percentages following septoplasty demonstrated that the satisfaction levels of the patients were increased. Upper airway obstruction secondary to NSD may affect ABPM measurements. Moreover, the significant decrease in the 24SBP, DSBP, NSBP, 24PP and DPP following septoplasty showed that NSD may cause cardiovascular risk and this risk may be prevented by septoplasty.

Objectives/hypothesis To investigate causative viruses in patients with postviral olfactory disorders (PVOD). Study design Case-control study. Methods One hundred fifty-one consecutive patients diagnosed with PVOD were enrolled, and samples from 38 patients who visited the doctor within 3 months of symptom onset were collected and analyzed. Thirty-two individuals who underwent surgery for nasal septal deviation during the same time period were collected as the control group. The Sniffin' Sticks psychophysical olfactory test was used to evaluate olfactory function. Olfactory cleft specimens were collected using nasopharyngeal flocked swabs (COPAN FLOQSwabs). Eighteen viruses were tested for with the Luminex xTAG RVP FAST v2 Assay Kit. Results Out of the 38 patients with PVOD, rhinoviruses were detected in 13 patients, and coronavirus OC43 was detected in one patient. The frequency of positive virus detection in the patients with anosmia was higher than in those with hyposmia (58.8% vs. 19.0%, P = 0.018). In control group, rhinovirus was identified in one patient (3.1%). Nasal obstruction was the most common symptom and was experienced by 71.0% of patients. Conclusions Rhinovirus and coronavirus are more commonly identified in PVOD. Our methods represent an approach to screen for viruses that may be involved in PVOD.

OBJECTIVES/HYPOTHESIS Standard spreader grafts (SSGs) are commonly used in septorhinoplasty to treat internal nasal valve narrowing and have been shown to improve nasal airway obstruction. Extended spreader grafts (ESGs) have also been proven effective for correcting nasal deviation. To date, the effectiveness of ESGs using patient-reported outcome measures has not been demonstrated, and results of ESGs have not been compared to SSGs. This study aims to assess satisfaction and nasal appearance in patients who have undergone septorhinoplasty with SSG versus ESG. STUDY DESIGN Prospective cohort study. METHODS Five hundred sixty-eight patients who underwent septorhinoplasty with SSGs and 126 patients who underwent septorhinoplasty with ESGs between 2012 and 2018 were administered the Nasal Obstruction Symptom Evaluation (NOSE) scale and FACE-Q Satisfaction With Nose, FACE-Q Satisfaction With Nostrils, and FACE-Q Social Functioning scales pre- and postoperatively. Pre- and postoperative NOSE and FACE-Q scores, negative inspiratory force (NIF), and changes in these values were compared between groups. RESULTS Results demonstrated clinically and statistically significant improvement at follow-up for both groups. There was no significant difference between the SSG and ESG groups in mean improvement of NOSE scores, FACE-Q scores, and NIF at follow-up of 6 months and at 12 months. CONCLUSIONS This study demonstrates that SSGs and ESGs both provide clinically and statistically significant improvement, and no significant difference in functional outcome. Both techniques can be effective. The etiology of the nasal obstruction and/or deformity should be considered when deciding which type of spreader graft to use.

Objective Patients suffering from persistent inferior turbinates hypertrophy refractory to medical treatments require surgical intervention where the main aim is symptomatic relief without any complications. Extraturbinoplasty is one of the preferred procedures for turbinate reduction due to its efficacy in freeing up nasal space by removing the obstructing soft tissue and bone while preserving the turbinate mucosa. We sought to evaluate the effectiveness and safety of microdebrider assisted turbinoplasty (MAT) and coblation assisted turbinoplasty (CAT) performed as an extraturbinoplasty procedure. Methods A prospective randomized comparative trial was conducted among patients with bilateral nasal blockage secondary to inferior turbinates hypertrophy. Patients were randomly assigned to MAT or CAT. An extraturbinal medial flap turbinoplasty was performed for both techniques. Symptom assessment was based on the visual analogue score for nasal obstruction, sneezing, rhinorrhea, headache and hyposmia. Turbinate size, edema and secretions were assessed by nasoendoscopic examination. The assessments were done preoperatively, at 1st postoperative week, 2nd and 3rd postoperative months. Postoperative morbidity like pain, bleeding, crusting and synechiae were documented. The clinical outcomes of both techniques were analyzed using repeated measures ANOVA. Results A total of 33 participants were recruited, 17 patients randomized for MAT and 16 patients for CAT. Nasal obstruction, discharge, sneezing, headache and hyposmia significantly reduced from 1st week until 3 months for both procedures. Similar significant reductions were seen for turbinate size, edema and secretions. However, there was no significant difference in symptoms and turbinate size reduction were seen between both groups at the first postoperative week, 2nd and 3rd postoperative months. There was significant longer operating time for CAT when compared to MAT (p = 0.001). The postoperative complications of bleeding, crusting and synechiae did not occur in both groups. Conclusion Both MAT and CAT were equally effective in improving nasal symptoms and achieving turbinate size reduction in patients with inferior turbinate hypertrophy. Both MAT and CAT offer maximal relieve in patients experiencing inferior turbinates hypertrophy by removing the hypertrophied soft tissue together with the turbinate bone without any complications.

Background: Understanding the multidimensional postoperative patient experience after rhinoplasty is critical for preoperative counseling and postoperative management. Methods: A prospective clinical study was conducted from June to December 2019 for 60 patients undergoing cosmetic and/or functional rhinoplasty by two facial plastic surgeons. All patients were administered the brief pain inventory, a clinically validated pain instrument, including multiple quality of life (QOL) domains, survey at postoperative days (PODs) 1, 2, 3, and 8. Nasal Obstruction Symptom Evaluation (NOSE) scores were used to predict patients having greatest QOL disturbance. Primary outcomes were postoperative QOL domains, pain scores, and oxycodone usage. Statistical analysis was performed using STATA 14.0 (STATA Corp., College Station, TX). Preoperative NOSE and postoperative Euro Quality of Life 5-Dimension scores were also recorded. Results: Patients showed greatest disruption to QOL in the first 3 PODs and essentially returned to normal levels by POD8, which mirrored trends in pain and opioid usage. All tested QOL domains (general activity, sleep, work, mood, enjoyment, and relationships) were strongly correlated with overall pain. NOSE scores were not significantly associated with pain or QOL impairment. Conclusions: This is the first study to prospectively evaluate the rhinoplasty patient's postoperative experience using a pain instrument, including multiple QOL domains. Utilizing a validated clinical instrument allows for standardized comparison of postrhinoplasty pain and QOL disruption with other surgical procedures and disease processes. These data may help guide preoperative counseling and set accurate patient expectations for the postoperative period.

Background For years, the benefits of septoplasty have been questioned. Due to the scarce and inconclusive literature, several National Health Service (NHS) Clinical Commissioning Groups in England decided to add septal surgery to their list of restricted procedures with low clinical value. Recently, evidence was obtained that septoplasty is actually more effective than non-surgical management for nasal obstruction in adults with a deviated septum. However, the relation between costs and effects of septoplasty remains unknown. Methods We conducted an economic evaluation alongside an open, multicenter, pragmatic randomized controlled trial in two tertiary and 16 secondary referral hospitals in the Netherlands. Adults with nasal obstruction and a deviated septum were randomized to (1) septoplasty with or without concurrent turbinate surgery or (2) non-surgical management consisting of (a combination of) medical treatment and watchful waiting. Analyses were performed on an intention-to-treat basis. Single imputation nested in the bootstrap percentile method (using 5000 bootstrap replications) was performed to assess the effect of missing data. After 12 and 24 months, we assessed the incremental costs per quality-adjusted life year (QALY) gained from a healthcare and a societal perspective. Results A total of 203 adults were randomly assigned to septoplasty (N = 102) or non-surgical management (N = 101). After 12 months, the mean cost difference between septoplasty and non-surgical management using a healthcare or societal perspective was €1181 (95%CI €1038 to €1323) or €2192 per patient (95%CI €1714 to €2670), respectively. The mean QALY difference was 0.03 per patient (95%CI − 0.01 to 0.07). Incremental costs per QALY gained from a healthcare or societal perspective were €41,763 or €77,525, respectively. After 24 months, the mean cost difference between the two groups using a healthcare or societal perspective decreased to €936 (95%CI €719 to €1153) or €1671 per patient (95%CI €952 to €2390), respectively. The mean QALY difference increased to 0.05 per patient (95%CI − 0.03 to 0.14). Incremental costs per QALY gained from a healthcare or societal perspective became €17,374 or €31,024, respectively. Analyses of imputed data did not alter our findings. Conclusions Depending on the selected perspective, cost-effectiveness threshold, and time horizon, septoplasty has the potential to be cost-effective. Despite considerable uncertainty, septoplasty seems to be cost-effective from a healthcare perspective, after 24 months against a threshold of €20,000 per QALY. From a societal perspective, septoplasty is not yet cost-effective after 24 months, but it comes closer to the cost-effectiveness threshold as time passes by.

Introduction: Nasal obstruction is one of the most frequent otolaryngologic complaints; and the collapse of the internal nasal valve is one the main causes of the nasal air flow obstruction. Objective: We aimed to evaluate internal nasal valve by using reformatted CT-scans pre- and post- rhinoplasty at 3 months and to assess its correlation to symptomatic improvement of nasal obstruction using the NOSE scale. Methods: A prospective observational study was conducted between March 2017–May 2018 in a tertiary care otorhinolaryngology center. We included patients suffering from nasal obstruction secondary to internal nasal angle collapse and nasal deformity. Patients with sinusitis, nasal polyposis, and nasal masses were excluded. Results: Twenty consecutive patients underwent rhinoplasty, with a mean age (22.2 ± 2.8), with majority of males (n = 14; 70%). There was no significant correlation between pre- and post- CT-scans of the internal nasal valve angle/area and NOSE scores. A high significant difference was detected between mean pre- and post- NOSE scores (p
