Article Abstract
Aim: To evaluate the utility of ApneaGraph® AG 200 in diagnosing Obstructive Sleep Apnoea (OSA) as compared to Polysomnography, localization of the site of upper airway obstruction, and the success rate of surgery.
Methods: A prospective study was conducted including fifteen patients of OSA undergoing surgical treatment. All patients underwent sequential overnight ApneaGraph (AG) and Polysomnogram (PSG) before and after 3 months following surgery. The preoperative and post-operative Apnoea-Hypopnoea Index (AHI) values were compared between AG and PSG. The success of surgery was defined as mean reduction in AHI by ≥ 50% and post-operative AHI < 20.
Results: The mean preoperative AHI using PSG was 53.7 and using AG was 44.9 (r = 0.83, p = 0.0001). All patients underwent AG-directed site-specific surgery. The mean postoperative AHI using PSG was 15.3 and using AG was 13.8 (r = 0.67, p = 0.0062). There was significant improvement in AHI post-surgery (p < 0.05, AG & PSG). The surgical success was achieved in 93.3%. The median follow-up was 14 months.
Conclusion: ApneaGraph is a reliable alternative to PSG to diagnose OSA with an added advantage to localize the site of obstruction, yielding good surgical outcomes.

ObjectiveTo compare between L pharyngeal flap alone and combined L pharyngeal flap with phenytoin for repair of palatal fistula and velopharyngeal insufficiency (VPI).MethodsTwenty patients with soft palate fistula and persistent VPI who were divided into two groups. In the first group, superiorly based L pharyngeal flap was harvested from the oropharynx and inserted into the soft palate to close the fistula after fistula trimming.

Introduction: It is well known that Obstructive Sleep Apnea (OSA) is a complex disease characterized by an Upper Airway (UA) collapse during sleep, with potential consequences on ENT districts. Recent evidence suggests a possible association with Eustachian Tube Dysfunction (ETD). However, the potential effects of both surgical and non-surgical therapeutic strategies on ET function remain poorly explored in the current literature.

Purpose: Sleep disturbance is prevalent in long-term care facilities (LTCFs), yet there is limited understanding of individual factors predicting changes in sleep within these populations. Our objective was to determine predictors of sleep disturbance in LTCFs and investigate variation in prevalence across facilities in two Canadian provinces-New Brunswick and Saskatchewan.
Method: This retrospective longitudinal cohort study used interRAI comprehensive health assessment data from 2016 to 2021, encompassing 21,394 older adults aged ≥ 65 years across 228 LTCFs.

A 48-year-old man with a superior labral tear and medical history including hemidiaphragmatic paresis, obstructive sleep apnea, vocal cord paresis, and glottic narrowing, underwent arthroscopic biceps tenodesis. Reduction in respiratory function presented anesthetic management challenges with general anesthesia or an interscalene brachial plexus block. Instead, ultrasound guidance was used to deliver a selective upper-trunk block with 1 % lidocaine and an axillary nerve block with 0.
