睡眠呼吸暂停是白天嗜睡的主要原因。在提出的病因中，提出了咽部气道局灶性阻塞，但未得到证实。通过使用计算机断层扫描，可以容易地评估气道的横截面积。成人（33）临床证实的睡眠呼吸暂停和12名正常成人进行了系统的颈部计算机断层扫描。所有阻塞性睡眠呼吸暂停患者的气道均明显变窄，而对照组则无明显变窄。在11例患者中，狭窄发生在单个节段，而在22例患者中，2个或更多节段受到影响。结构异常的气道可能是睡眠呼吸暂停发生的解剖学基础。根据这一证据，2例患者行悬雍垂腭咽成形术，1例症状缓解。
Sleep apnea is a major cause of daytime hypersomnolence. Among the proposed etiologies, focal obstruction of the airways at the level of the pharynx was suggested but not proven. By using computed tomography, the cross-sectional area of the airway can be readily assessed. Adults (33) with clinically proven sleep apnea and 12 normal adults underwent systematic computed tomography of the neck. Significant airway narrowing was demonstrated in all the patients with obstructive sleep apnea, whereas no such narrowing was seen in the controls. In 11, the narrowing was at a single level, whereas in 22 patients 2 or more levels were affected. A structurally abnormal airway may serve as an anatomic substrate for the development of sleep apnea. On the basis of this evidence, uvulopalatopharyngoplasty was performed in 2 patients with relief of symptoms in 1.
