Objectives: In clinical practice, lateral nasal wall collapse during forced inspiration is widely regarded as a sign of nasal obstruction or criterion indicating nasal valve surgery. This study aims to evaluate the relationship between the degree of lateral nasal wall collapse and subjective nasal obstruction. In addition, factors related to lateral nasal wall collapse were also investigated. Methods: In this study, lateral nasal wall collapse is determined by the degree of lateral nasal wall triangle (LNWT) area reduction on frontal view during forced inspiration compared to quiet inspiration. LNWT area ratio of the patient and control groups was compared. The relationship between the lateral nasal wall collapse and clinical factors including symptom scores, nasal valve angles, skin thickness were evaluated. Results: The average LNWT area ratio of the patient (n = 24) and control groups (n = 27) was 0.96 and 0.83 respectively (P =.001). Symptom score (NOSE and VAS) is not related to the degree of lateral nasal wall collapse. Moreover, nasal valve angle and skin thickness were also not related to the degree of lateral nasal wall collapse. In 14 of the 19 patients, the more obstructed side corresponded to the side of narrower nasal valve angle, and 5 were not. Conclusion: Lateral nasal wall collapse is not related to a patients' nasal obstruction. [ABSTRACT FROM AUTHOR]

Adenotonsillectomy is the most commonly performed surgery in children. To evaluate the effects of pediatric adenotonsillectomy on health care utilization. From 2006 to 2017, age/sex-matched adenotonsillectomy participants (n = 243.396) and controls (n = 730.188) were selected (62% of male and 38% of female. 47% age≦ 6, 16% 7–9years, 8% 10–12years, 29% 13–18years). The changes in outpatient visits, hospitalization days, and drug prescriptions due to a URI, asthma, and rhinitis before and after the surgery date (from 13 months to 1 month) were compared. Outpatient visits decreased more in the surgery group than the control group (mean change, 3.24 ± 8.61 d and 1.16 ± 6.57 d for URI, 2.07 ± 8.63 d and 0.51 ± 6.47 d for rhinitis, and 0.72 ± 4.81 d and 0.42 ± 3.91 d for asthma, p <.001 for all). Hospitalizations also showed greater decreases in the surgery group (mean change, 0.31 ± 2.96 d and 0.04 ± 1.70 d for URI, 0.13 ± 2.40 d and 0.02 ± 1.48 d for rhinitis, 0.11 ± 2.32 d and 0.04 ± 1.83 d for asthma, p <.001 for all). The prescription of antihistamines, leukotriene modulators, oral antibiotics, oral steroids, and expectorants, cough suppressants and oral bronchodilators was also decreased after surgery. The adenotonsillectomy group showed a greater decrease in post-operative outpatients visits, hospital days and drug prescriptions associated with URI, rhinitis and asthma than the control group.

Background: Low concentrations of hypochlorous acid (HOCl) have proven antipruritic, anti-inflammatory, and antimicrobial effects without toxicity, although the mechanism has not been fully elucidated. Objective: The aim of this study was to evaluate the effectiveness of HOCl nasal irrigation to reduce allergic rhinitis (AR) symptoms compared with saline nasal irrigation. Methods: This was multicenter, randomized, double-blind, placebo-controlled study. Initially, 139 patients with perennial AR were enrolled; however, 25 did not successfully complete the study. Patients were randomly assigned to the nasal irrigation with low-concentration HOCl (n = 55) or normal saline (n = 59) treatment groups for the 4-week study period. Participants completed the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) at every visit (baseline, Weeks 2 and 4), and Total Nasal Symptom Score (TNSS) was determined before and after nasal irrigation every morning and evening. Results: We found that RQLQ scores significantly decreased after 4 weeks in the HOCl and placebo groups, but the decrement of the RQLQ score was similar between the 2 groups. Additionally, TNSS improved in both groups between baseline and Week 4, whereas there were no significant differences in the change of TNSS between the 2 groups. The HOCl group did not show any clinical side effects related to nasal irrigation. Conclusion: Allergic symptoms significantly decreased with low-concentration HOCl nasal irrigation, without significant adverse events. However, HOCl showed no additional improvement in symptoms compared with saline nasal irrigation for patients with perennial AR. [ABSTRACT FROM AUTHOR]

Objectives: Immediate facial nerve substitution or graft technique has been used for the repair of facial nerve defects occurring as a result of tumour dissection. However, some patients report unsatisfactory outcomes, such as difficulty in maintaining resting or smiling symmetry, due to persistent flaccid facial palsy. Here we evaluated the functional outcomes of transferring the masseteric branch of the trigeminal nerve to the facial nerve adjunct to facial nerve graft. Methods: We reviewed the medical records of seven patients who underwent facial reanimation surgery between 2014 and 2016. The patients were divided into two groups according to the type of facial reanimation surgery: group A, masseteric nerve innervation with interposition graft; group B, interposition graft only. The postoperative resting symmetry and dynamic movement were compared. Results: Facial contraction was first observed in group A at 4 months and in group B at 7.3 months. Most of the patients achieved reliable resting symmetry; however, one patient in group B exhibited unsatisfactory facial weakness on the affected side. Group A patients showed better dynamic movement than group B patients. Eye closure, oral excursion and oral continence were better in group A than in group B patients. Smile symmetry in both groups was similar due to hyperkinetic movement in group A patients and flaccidity in group B patients. Conclusions: Dual innervation of the masseteric branch of the trigeminal nerve improves the dynamic movement of paralysed facial muscles and shortens the recovery period in patients with iatrogenic facial palsy.

Objectives: This study aimed to compare the characteristics of idiopathic unilateral vocal fold paralysis (IUVFP) in elderly versus younger patients, including the diagnostic yield of computed tomography (CT) scans for identifying the structural causes of IUVFP. Methods: We retrospectively analyzed medical records of the patients initially diagnosed with IUVFP in a single referral tertiary hospital. We compared patients’ baseline characteristics, initial symptoms, laryngoscopic findings, and prevalence of structural causes on CT scans with respect to age (younger, <65 years vs older, ⩾65 years). Results: One hundred forty-two patients were enrolled (90 younger, 52 older). Evident structural causes were more frequently found on CT in older patients than younger patients (40.4% vs 22.2%, P = .034). Among truly idiopathic cases (70 younger, 31 older), recovered vocal fold mobility was identified in 48.6% younger and 41.9% older patients (P = .666). There was no statistically significant difference in the characteristics between unrecovered and recovered subjects of the older patients with true IUVFP (all P > .05). Conclusions: The CT scans provided significantly higher diagnostic yields in older patients than younger patients. The degrees of symptoms and complications and likelihood of natural recovery did not significantly differ between younger and older patients with IUVFP. [ABSTRACT FROM AUTHOR]

Objectives: Timely and accurate diagnosis of nasal bone fractures (NBFs) is crucial for preserving the cosmetic and functional aspects of the nose. This study aims to identify factors influencing radiographic and computed tomography (CT) diagnosis of NBF in patients with nasal trauma., Methods: Two hundred six patients with acute nasal trauma underwent both conventional radiography and facial bone CT. An experienced otorhinolaryngologist independently interpreted images. Results were categorized into "Concordance" or "Discrepancy" groups, with demographic and clinical data compared., Results: The study classified 167 patients into "Concordance" and 39 into "Discrepancy" groups based on radiography and CT interpretations. The "discrepancy group" showed higher rates of previous nasal bone fractures (P=0.044), rhinoplasty history (P=0.044), and concomitant facial bone fractures (P=0.001). Adjusted odds ratios revealed significant associations between discrepancies and a history of nasal bone fracture (OR=5.197, 95% CI 1.165-23.171), rhinoplasty (OR=6.114, 95% CI 1.393-26.847), and concomitant facial bone fractures (OR=3.765, 95% CI 1.663-8.523)., Conclusion: This study highlights the impact of facial trauma, including rhinoplasty, on the radiological diagnosis of NBF. Consequently, in the presence of signs of concurrent facial trauma, previous nasal trauma, or rhinoplasty history, a prompt CT scan and comprehensive evaluation are recommended for accurate diagnosis and timely treatment, ultimately improving the patient's prognosis., Competing Interests: The authors report no conflicts of interest., (Copyright © 2024 by Mutaz B.

Objectives: This study aimed to compare positive airway pressure (PAP) therapy compliance between patients with comorbid insomnia and sleep apnea (COMISA) and those with obstructive sleep apnea (OSA) alone. It also assessed the influence of insomnia clinic visits on PAP compliance., Methods: Patients diagnosed with OSA and initiated on PAP therapy between January 2012 and December 2021 were included. The COMISA group (n=43) comprised patients with insomnia, while the control group (n=86) consisted of OSA patients without insomnia, matched 1:2 based on age and sex. COMISA patients were further categorized into group A (n=20), with at least two insomnia clinic visits, and group B (n=23) with one or no visits. PAP compliance in each group was evaluated at 3 and 9 months., Results: No significant differences were observed in PAP compliance between the COMISA patients and OSA patients without insomnia. Within the COMISA group, the impact of insomnia clinic visits on PAP compliance was not significant. No significant difference was observed in daily PAP usage between the two groups at 3 months (265.5±145.9 minutes in group A vs. 236.3±152.3 minutes in group B, P=0.760) or 9 months (213.4±155.3 minutes in group A vs. 166.3±158.3 minutes in group B, P=0.538). The percentages of PAP users and nights with PAP use exceeding 4 hours also showed no significant differences at either time point., Conclusion: This study demonstrated no significant disparity in PAP compliance between the COMISA and OSA groups at either 3 or 9 months. Furthermore, insomnia clinic visits did not significantly impact PAP compliance in COMISA patients during 3- and 9-month intervals.

Objectives: We aimed to compare clinical outcomes including hearing improvement and cholesteatoma recurrence between endoscopic and conventional microscopic surgeries in patients with attic cholesteatoma., Methods: We collected data from patients with attic cholesteatoma who were treated using endoscopic (10 patients) and microscopic (10 patients) approaches by a single surgeon. The data were retrospectively reviewed for patient characteristics, intraoperative findings, hearing levels, and follow-up clinical status. Recurrence of the cholesteatoma, improvement of hearing, and operation time were evaluated., Results: Ossiculoplasty was performed in four patients in the endoscopic group and two patients in the microscopic group. Lempert endaural incision II was used in all the patients in the microscopic group, whereas Lempert I incision was used in all the patients in the endoscopic approach group. There were no significant differences between the two groups regarding hearing improvement and operating time. And, there were no recurrences during the follow-up period in both groups., Conclusion: The endoscopic approach for the management of attic cholesteatoma is as useful as the microscopic approach.
