阻塞性睡眠呼吸暂停低通气综合征(OSAHS)病因学复杂,涉及上气道解剖狭窄、咽肌功能下降、咽壁顺应性增加、肥胖、咽神经感受功能下降、中枢通气控制障碍、肺功能残气量下降和内分泌等。目前,睡眠呼吸外科上气道阻塞评估还局限在了解上气道解剖狭窄、咽壁的顺应性、肥胖等 Obstructive sleep apnea-hypopnea syndrome (OSAHS) etiology is complex, involving the upper airway anatomy narrowing, decreased pharyngeal muscle function, pharyngeal wall compliance, obesity, decreased pharyngeal nerve sensory function, central ventilation control disorders, pulmonary function disorders Gas decreased and endocrine and so on. At present, assessment of airway obstruction in sleep and respiratory surgery is also limited to understanding the limitations of upper airway anatomy, compliance of the pharyngeal wall, obesity, etc.
