对２０例年龄在４０～６３岁的阻塞性睡眠呼吸暂停综合征（ＯＳＡＳ）患者予以悬雍垂腭咽成形术（ＵＰＰＰ）治疗，连续观察手术前、后睡眠期血压及血气情况。结果：手术前２０例患者皆合并有高血压及夜间低氧血症，术后得以纠正，手术前、后比较有显著性差异（Ｐ＜０．０１），睡眠期打鼾及呼吸暂停也得以改善。提示：对由阻塞性睡眠呼吸暂停引起的高血压患者，选择性的使用悬雍垂腭咽成形术是一种有效的治疗方法。 Uvulopalatopharyngoplasty (UPPP) was performed on 20 patients aged 40-63 years with obstructive sleep apnea syndrome (OSAS). Blood pressure and blood gas were monitored continuously before and after sleep. Results: All the 20 patients before surgery were complicated with hypertension and nocturnal hypoxemia, and were corrected after operation. There were significant differences before and after operation (P <0.01), and snoring and apnea during sleep were also improved . Hint: Selective use of uvulopalatopharyngoplasty is an effective treatment for hypertensive patients with obstructive sleep apnea.
