Obstructive sleep apnea syndrome (OSAS) is defined as intermittent complete or partial upper airway obstruction during sleep, causing mental and physical effects. Localization of obstructions in the upper airways in OSAS patients provides indispensable information for the selection of surgical procedures. We measured the pressure within the upper airways during sleep in 6 patients with OSAS in order to select the surgical procedure. Five patients were found to have the airway collapse in the velopharynx, and in three of them underwent uvulopalatopharyngoplasty (UPPP) with tonsillectomy was performed. The remaining one patient, having an obstruction in both the velopharynx and hypopharynx, underwent laser-assisted midline glossectomy as well as UPPP. The 4 patients receiving the operation showed improvements in the sleep apnea index and the lowest oxygen saturation postoperatively. These findings suggest that pressure measurement may be a reliable tool for localizing obstructions in OSAS patients and may be used for determined the surgical option.
阻塞性睡眠呼吸暂停综合征（OSAS）的定义为睡眠期间间歇性完全或部分上气道阻塞，从而导致身心方面的影响。OSAS患者上气道阻塞部位的定位为手术方式的选择提供了不可或缺的信息。我们对6例OSAS患者在睡眠期间的上气道压力进行了测量，以便选择手术方式。发现5例患者的气道在腭咽部位塌陷，其中3例接受了悬雍垂腭咽成形术（UPPP）并进行了扁桃体切除术。其余1例患者在腭咽和下咽均有阻塞，接受了激光辅助中线舌切除术以及UPPP。4例接受手术的患者术后睡眠呼吸暂停指数和最低血氧饱和度均有改善。这些发现表明，压力测量可能是定位OSAS患者阻塞部位的可靠工具，可用于确定手术方案。
