对１６例因阻塞性睡眠呼吸暂停综合征拟行悬雍垂腭咽成形术（ＵＰＰＰ）者，术前在纤维内窥镜下行Ｍüｌｌｅｒ′ｓ动作观察。结果是：以软腭水平狭窄或阻塞为主者１１例（甲组），以喉咽水平狭窄或阻塞为主者５例（乙组）。ＵＰＰＰ后甲组１１例中８例获得较好疗效，有效率７２．７％；乙组５例中仅１例有效，有效率２０％。两组间疗效差别显著。提示术前行Ｍüｌｌｅｒ′ｓ动作观察，了解咽腔阻塞或狭窄水平，可作为临床选择ＵＰＰＰ适应证、提高ＵＰＰＰ疗效的有效方法。
16 cases of obstructive sleep apnea syndrome proposed uvulopalatopharyngoplasty (UPPP), preoperative Müller’s motion under fiber endoscopy observed. The results were as follows: 11 cases (group A) were mainly stenosed or obstructed with soft palate, and 5 cases were mainly stenosis or obstruction of laryngopharyngeal (group B). UPPP group A 11 cases in 8 cases to obtain better curative effect, the effective rate of 72.7%; B group of 5 cases in only 1 case, the effective rate of 20%. The difference between the two groups was significant. Prompt Müller’s motion observation before surgery to understand the pharyngeal obstruction or stenosis level, as a clinical choice UPPP indications, to improve the efficacy of UPPP an effective method.
