阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的发生受多种因素影响,其中上呼吸道解剖性狭窄和局部软组织的易塌陷性,使在睡眠中上呼吸道对气流机械性阻塞增加,被认为是重要的因素。Ⅱ型OSAHS患者阻塞平面在口咽部,黏膜组织肥厚致悬雍垂肥大或过长、软腭过低过长、咽侧索肥厚、扁桃 Occurrence of obstructive sleep apnea-hypopnea syndrome (OSAHS) is influenced by a number of factors, including anatomical stenosis of the upper airway and local collapsibility of the soft tissue, which increases mechanical obstruction of the upper airway during sleep and is considered to be Important factor.
