Uvulopalatopharyngoplasty (UPPP) was performed in 12 patients with obstructive sleep apnea. Pre-surgical clinical and polysomnographic data were compared with those one to three months after surgery. Excessive daytime sleepiness was partially improved in 4 cases and completely abolished in 8. Total sleep time, sleep efficiency, number of arousals and sleep latency were similar in both evaluations. REM latency to stage 2 markedly increased on the follow-up. Stage distributions were similar in both nights except for stage 4 which was more frequently absent on the first recording. SaO2 levels below 80% were seen in 10 cases before UPPP and in 4 after it. Apnea index decreased in all cases but it reached normal levels only in 4.
对12例阻塞性睡眠呼吸暂停患者实施了悬雍垂腭咽成形术（UPPP）。将术前临床和多导睡眠图数据与术后1至3个月的数据进行比较。4例患者白天过度嗜睡症状得到部分改善，8例完全消失。两次评估中总睡眠时间、睡眠效率、觉醒次数和睡眠潜伏期相似。随访时快速眼动睡眠到第二阶段的潜伏期显著增加。除了在首次记录中更频繁缺失的第四阶段外，两晚的睡眠阶段分布相似。UPPP术前10例患者血氧饱和度（SaO2）水平低于80%，术后4例。所有病例的呼吸暂停指数均下降，但仅4例达到正常水平。
