Sleep medicine is an important component of current head and neck surgery practices. Furthermore, obstructive sleep apnea is an anatomic disease of the upper respiratory tract, a region of anatomy best known to head and neck surgeons. If head and neck surgeons choose to participate in the surgical treatment of sleep apnea, they must develop expertise in the evaluation and home sleep testing asp...

This article has reviewed the anatomic, compliance, reflex, and respiratory muscle variables that affect upper airway caliber and abnormalities which may precipitate upper airway collapse during sleep. One or more of these variables may be important in the mechanism of OSA in any given patient. First, anyone with anatomic narrowing of the upper airway is susceptible to OSA. However, we do know ...

One of the most serious adverse events associated with anterior cervical spine surgery is wound hematoma resulting in airway compromise. The reported incidence of this postoperative complication has varied from 0.2% to 1.9%. Obstruction of the airway secondary to bleeding presents a challenging clinical scenario given the rapidity of onset, distorted anatomy of the upper respiratory tract, urge...

Upper airway pressure was measured during maximal exercise in 10 Thoroughbred racehorses with naturally occurring upper airway obstruction. Left laryngeal hemiplegia and arytenoid chondropathy resulted in substantial increases (30-40 cm H2O) in inspiratory upper airway pressure (Pl), whereas complicated aryepiglottic entrapment and subepiglottic cysts produced only modest increases (15 cm H2O) ...

Congenital pulmonary airway malformation (CPAM) is a very rare pulmonary disease in children. It is often misdiagnosed as a persistent and localized pneumothorax without any further pathological diagnosis. Malignancy and frequent airway infections are major concerns in these patients. Surgical excision is recommended to make a definite diagnosis and exclude hidden malignancies, and is also the ...

conclusions pharyngeal airway dimensions, soft palate length, thickness, and position, and hyoid position are not significantly different between skeletal class i and class ii prepubertal children. results no significant difference in the upper airway, soft palate, and hyoid variables was found between the two groups (p > 0.05) and no correlation was found between anb difference and the other v...

An African-American man, aged 34 years, underwent an elective uncomplicated right wrist laceration repair while under general anesthesia. Following extubation, the patient developed hypoxemia, tachypnea, shortness of breath, pulmonary rales, frothy sputum, decreased oxygen saturation, and evidence of upper airway obstruction. Chest radiograph showed pulmonary edema. The patient was diagnosed wi...
