Mandibulectomy most commonly performed as surgical management of oropharyngeal carcinoma leads to a wide array anatomical and physiological changes which result in an anticipated difficult airway. There may be posterosuperior displacement hyoid bone tongue leading reduction retropalatal space along with loss structural support the predisposing it prolapse development obstructive sleep apnoea. B...

A modified nasopharyngeal tube is described that does not add airway dead space and resistance, is well tolerated, highly successful, and allows simultaneous use of oxygen prongs. This potentially reduces the need for surgical intervention to relieve high upper airway obstruction from Pierre-Robin syndrome and other causes.

Mucus clearance is an important airway innate defense mechanism. Airway-targeted overexpression of the epithelial Na(+) channel β-subunit [encoded by sodium channel nonvoltage gated 1, beta subunit (Scnn1b)] in mice [Scnn1b-transgenic (Tg) mice] increases transepithelial Na(+) absorption and dehydrates the airway surface, which produces key features of human obstructive lung diseases, including...

Syndromic craniosynostosis is associated with a high rate of respiratory difficulty, due mainly to midfacial hypoplasia. Nasopharyngeal airway establishment has been reported as the first-line approach to airway obstruction and may obviate the need for a highly invasive tracheotomy. No previous studies have compared airway obstruction status in syndromic craniosynostosis between cases requiring...

Objective: Recent years have witnessed a renewed interest to determine a quantifiable relationship between mandibular advancement performed with an orthodontic appliance and the resulting airway dimensions and volume. The study was conducted to evaluate the changes in dimensions of pharyngeal airway space using computed tomography (CT) in Class II division 1 patients with retrognathic mandible ...

The purpose of this research was to elucidate the relationship between tonsillar hypertrophy and Obstructive Sleep Apnea Syndrome (OSAS) in terms of cephalometric analysis, as well as to determine factors that affect OSAS severity. 25 patients were enrolled in this study. Lateral cephalograms of the subjects were taken. Disease severity was evaluated by the Apnea Hypopnea Index (AHI). Cephalome...

We present a fast and robust supervised algorithm for labeling anatomical airway trees, based on geodesic distances in a geometric tree-space. Possible branch label configurations for a given tree are evaluated based on distances to a training set of labeled trees. In tree-space, the tree topology and geometry change continuously, giving a natural way to automatically handle anatomical differen...

Peritonsillar abscess in children younger than 5 years old has rarely been reported in the literature. We present the case of a 22-month-old child with a right peritonsillar abscess with parapharyngeal spread that was complicated by airway obstruction secondary to rapid epiglottic swelling. The severity of the airway obstruction necessitated an urgent tracheostomy, incision and drainage of the ...
