作者１９９７年６月至１９９８年２月对２１例ＯＳＡＳ患者进行了半导体激光悬雍垂腭咽成形术，手术半年以后对所有患者做了睡眠监测随访，以呼吸紊乱指数（ＡＨＩ）下降５０％为有效计算，手术有效率为５７．１４％；另外，对手术后Ｅｐｗｏｒｔｈ嗜睡评分（ＥＳＳ）、呼吸暂停指数（ＡＩ）、ＡＨＩ和最低血氧饱和度（ＬｏｗｅｓｔＳａＯ２）的改善情况做了对照分析，发现ＥＳＳ的下降与ＡＩ和ＡＨＩ的下降程度有显著差异，Ｐ值分别为０．００１９和０．００１５，说明患者术后嗜睡程度的改善不能代表客观指标的改善情况。
From June 1997 to February 1998, 21 OSAS patients underwent semiconductor laser uvulopalatopharyngoplasty. After six months of operation, all patients were followed up for sleep monitoring. The respiratory disturbance index (AHI) decreased by 50% In addition, the effective rate of operation was 57.14%. In addition, we compared the improvement of Epworth Sleepiness Score (ESS), apnea index (AI), AHI and LowestSaO2 after operation and found that There was a significant difference between the decline of ESS and the decline of AI and AHI, with P values of 0.0019 and 0.0015, respectively. This indicates that the improvement of postoperative somnolence can not represent the improvement of objective indexes.
