改良悬雍垂腭咽成形术治疗阻塞性睡眠呼吸暂停低通气综合征

Modified uvulopalatopharyngoplasty for obstructive sleep apnea-hyponea syndrome

目的：探讨扩展咽腔横径治疗阻塞性睡眠呼吸暂停低通气综合征的疗效。方法：对36例阻塞性睡眠呼吸暂停低通气综合征的患者。在行常规悬雍垂腭咽成形术（UPPP）后，将咽弓上缘向外上切开，充分外展咽弓，测量手术前后咽腔横径距离，与常规UPPP手术前后的咽腔扩展程度进行比较，并观察临床症状消失情况。砧果：手术后患者6个月有效率为81．12％，1年有效率为68．65％。改良UPPP手术后的咽腔较常规手术后咽腔增大1-2cm.结论：改良UPPP手术是扩展咽腔横径的有效方法，值得临床推广。

Objective： To explore the operation effect for obstructive sleep apnea hyponea syndrome（OSAHS） by enlarging pharyngeal space transverse diameter. Methods： A new kind of operation, modified uvulopalatopharyngoplasty（UPPP） was performed on 36 patients with OSAHS. The operation procedure included to split the superior edge of the palatopharyngeal bow forward to the lateral-superior direction, then to abduct the palatopharyngeal bow adequately, and at last to measure and compare the pharyngeal space before and after operation. Results： All the patients receiving the modified UPPP got a satisfied effect. The pharyngeal space increased by 1 - 2 cm compared with the result of routine UPPP. The curative rate of 6-month and 1-year was 81.12% and 68.65% respectively. Conclusion： The modified UPPP can enlarge pharyngeal space transverse diameter adequately and is a good method for OSAHS.
