A 7 week old infant was admitted with respiratory failure. Chest X-ray showed an atelectatic right upper lobe, herniation of right middle and lower lobe into the left thorax, and compression-atelectasis of the left lung. Thoracic CT showed complete occlusion of the right superior bronchus with a radiopaque foreign material. Six weeks prior, an impression for a palate plate using polyvinylsiloxane was taken. The material was removed with a rigid endoscopy, in readiness of extracorporeal oxygenation in case of tracheal obstruction or bronchial rupture...

Study Objectives: To determine whether arousals that terminate obstructive events in obstructive sleep apnea (OSA): 1. Induce hypocapnia and 2. Subsequently reduce genioglossus muscle activity following the return to sleep. Methods: 31 untreated OSA patients slept instrumented with: sleep staging electrodes, nasal mask and pneumotachograph, end-tidal CO2 monitoring and intramuscular genioglossus electrodes. End-tidal CO2 was monitored and respiratory arousals were assigned an end-arousal CO2 change value (PETCO2 on the last arousal breath minus each individual's wakefulness PETCO2)...

Study Objectives: Upper airway collapsibility is a key determinant of obstructive sleep apnea (OSA) which can influence the efficacy of certain non-CPAP treatment for OSA. However, there is no simple way to measure this variable clinically. The present study aimed to develop a clinically implementable tool to evaluate the collapsibility of a patient's upper airway. Methods: Collapsibility, as characterized by the passive pharyngeal critical closing pressure (Pcrit), was measured in 46 patients with OSA...

BACKGROUND: Several recent studies have suggested that 1 minus-forced expiratory volume expired in 3 seconds / forced vital capacity (1-FEV3/FVC) may be an indicator of distal airway obstruction and a promising measure to evaluate small airways dysfunction. AIMS: To investigate the associations of 1-FEV3/FVC with the spirometric measures and lung volumes that assess small airways dysfunction and reflects hyperinflation and air trapping. STUDY DESIGN: Retrospective cross-sectional study...

This case report illustrates how a multinodular goitre caused acute airway obstruction in a multitrauma 66-year-old male after tracheotomy. The patient had no symptoms of the goitre before the tracheotomy but developed subglottic airway obstruction at the time of decannulation. He underwent a subacute total thyroidectomy which removed the obstructive symptoms. A weakening of the tracheal tube followed by the tracheotomy possibly caused the tracheal stenosis in combination with the goitre.

The purpose of this study was to investigate the relationship between the pressure drop in the pharyngeal airway space (ΔPPAS) and the minimum cross-sectional area (minCSA) of the pharyngeal airway before and after mandibular setback surgery using computational fluid dynamics, in order to prevent iatrogenic obstructive sleep apnoea. Eleven patients with mandibular prognathism underwent bilateral sagittal split osteotomy for mandibular setback. Three-dimensional models of the upper airway were reconstructed from preoperative and postoperative computed tomography images, and simulations were performed using computational fluid dynamics...

BACKGROUND AND OBJECTIVE: Upper airway collapsibility predicts the response to several non-continuous positive airway pressure (CPAP) interventions for obstructive sleep apnoea (OSA). Measures of upper airway collapsibility cannot be easily performed in a clinical context; however, a patient's therapeutic CPAP requirement may serve as a surrogate measure of collapsibility. The present work aimed to compare the predictive use of CPAP level with detailed physiological measures of collapsibility...

BACKGROUND: The surgical excision of anatomic obstructions such as adenoids, palatine or lingual tonsils are commonly performed in children with sleep disordered breathing (SDB). Imaging studies measuring airway changes post-surgery in the SDB pediatric population are scarce, rarely addresses the nasal cavity, and are based on global measures (e.g. volume) that do not represent the complexity of the upper airway anatomy. The purpose of this pilot is to test the feasibility in using cone beam CT (CBCT) to analyze the nasal and pharyngeal airway space post-surgery using meaningful methods of analyses, and correlating imaging findings with clinical outcomes in children with SDB symptoms and maxillary-mandibular disproportion...

Treatment options for patients with obstructive sleep apnea (OSA) intolerant of continuous positive airway pressure (CPAP) are limited. Thus, new therapies are sought. Recently, there has been interest in using sedatives to delay arousal from sleep, allowing upper airway dilator muscle recruitment sufficient to re-open the airway while maintaining sleep. In this review the rationale for sedative use and prior sedative studies in OSA are presented, along with a description of six factors that may determine sedative treatment success...

OBJECTIVE: Drug induced sleep endoscopy (DISE) allows for preoperative evaluation of the specific site and character of upper airway obstruction in obstructive sleep apnea (OSA). We aim to assess the impact DISE has on customizing the surgical plan and evaluate its role in surgical success. METHODS: We retrospectively reviewed patients undergoing surgery for OSA. We compared those patients undergoing preoperative DISE to those that did not to assess procedures performed and surgical outcomes...

Chronic Lymphocytic Leukemia (CLL) is the most prevalent form of non-Hodgkin's lymphoma (NHL) in Western countries predominantly affecting adults over the age of 65. CLL is commonly indolent in nature but can present locally and aggressively at extranodal sites. Although CLL may commonly present with cervical lymphadenopathy, manifestation in nonlymphoid regions of the head and neck is not well described. CLL causing upper airway obstruction is even more uncommon. We describe a case of a patient with known history of CLL and stable lymphocytosis that developed an enlarging lymphoid base of tongue (BOT) mass resulting in rapid airway compromise...

Allergic inflammation in the upper airways represents a wide-spread health issue: Little is known about whether it increases sensitivity to airborne chemicals thereby challenging established exposure limits that neglect such differences in susceptibility. To investigate the role of pre-existing allergic inflammation, 19 subjects with seasonal allergic rhinitis (SAR) and 18 control subjects with low risk of sensitization were exposed for 4h to ammonia in two concentrations (cross-over design): 2.5ppm (odor threshold) and 0-40ppm (occupational exposure limit: 20ppm TWA)...

RATIONALE: The reduction in upper airway muscle activity from wakefulness to sleep plays a key role in the development of obstructive sleep apnea. Potassium (K+) channels have been recently identified as the downstream mechanisms through which hypoglossal motoneuron membrane excitability is reduced both in non-REM (NREM) and REM sleep. In animal models, the administration of 4-aminopyridine (4-AP), a voltage-gated K+ channel blocker, increased genioglossus activity during wakefulness and across all sleep stages...

This study evaluated the necessity of examining the upper airway in children with nocturnal enuresis. 225 children (aged 5-16 years), who were referred from the urology outpatient clinic between May 2015 and May 2016 and who had completed toilet training, were included in this study. Participants were separated into monosymptomatic nocturnal enuresis (MNE) (group 1) and without MNE (group 2) groups. Tonsil hypertrophy, adenoid vegetation, septal deviation, turbinate hypertrophy, allergic rhinitis, upper airway obstruction, and snoring etiology were assessed...

Obstructive sleep apnoea (OSA) is known to commonly co-exist with primary aldosteronism (PA), but it is unknown if treatment of PA improves sleep apnoea parameters in these patients. We therefore aimed to determine whether specific medical or surgical treatment of PA improves OSA, as measured by the apnoea-hypopnoea index (AHI). We recruited patients undergoing diagnostic workup for PA if they had symptoms suggestive of OSA. Patients with confirmed PA underwent polysomnography (PSG) at baseline and again at least 3 months after specific treatment for PA...
