11例严重阻塞性睡眠呼吸暂停综合征(OSAS)接受了悬雍垂腭咽成形术(UPPP),术后至少随访12个月。结论是,该手术对于严重OSAS无效。11例均有日间过度瞌睡,夜间多导睡眠图描记法(polysomnography,PSG)检查发现呼吸暂停指数>35,最低氧饱和度<75％。其中7例患高血压,3例充血性心力衰竭,3例红细胞增多症,10例肥胖症,9例CT显示口咽部平面狭窄。术前均能用鼻内持续气道正压法(CPAP)缓解。由耳鼻咽喉科医生做标准的UPPP,如扁桃体存在则切除之。其中3例还因鼻中隔偏曲行鼻中隔矫正术。术 Eleven patients with severe obstructive sleep apnea syndrome (OSAS) underwent uvulopalatopharyngoplasty (UPPP) and were followed up for at least 12 months. The conclusion is that this procedure is not valid for severe OSAS. All 11 patients had excessive daytime drowsiness, night polysomnography (polysomnography, PSG) examination found that the apnea index> 35, the lowest oxygen saturation <75%. Seven of them had hypertension, three had congestive heart failure, three had polycythemia, and 10 had obesity. Nine of them showed oropharyngeal stenosis. Preoperative nasal continuous positive airway pressure (CPAP) can be used to ease. A standard UPPP made by an otolaryngologist is removed if the tonsils are present. Three of them also suffered nasal septum deviation because of nasal septum deviation. Surgery
