悬雍垂腭咽成形术治疗睡眠呼吸障碍的有效性与安全性的系统评价

目的系统评价悬雍垂腭咽成形术(UPPP)治疗睡眠呼吸障碍的有效性及安全性.方法电子检索MEDLINE(1966～2005)、EMBASE(1984～2005)、Cochrane图书馆(2005年第1期)、中国生物医学文献光盘数据库(1979～2005)、中文学术期刊全文数据库(1994～2005)、中文科技期刊全文数据库(1989～2005),中文生物医学期刊数据库(1994～2005)、万方数据库以及互联网资料.文献检索语种限制为英文及中文.纳入有关UPPP的随机对照试验、半随机对照试验以及前瞻性对列研究.由两名研究者独立对纳入研究的方法学进行质量评价,资料统计分析采用RevMan4.2.7软件.结果共纳入12个研究,其中随机对照研究5个,前瞻性队列研究7个.UPPP与口腔矫形器(DA)比较,DA组多导睡眠呼吸监测(PSG)参数的改变优于UPPP组,但UPPP组术后生存质量评价及治疗依从性优于DA组;UPPP与激光悬雍垂腭咽成形术(LAUP)、低温等离子射频消融术(RFTVR)比较,后两者术后疼痛较UPPP组轻,术后并发症发生率UPPP与LAUP比较差异无统计学意义,与RFTVR比较除术后1周鼻腔反流的发病率较高外,其余差异无统计学意义.没有试验对UPPP与LAUP及RFTVR术后PSG参数的改变进行比较;与持续鼻腔正压通气比较,UPPP对PSG参数改变更优.结论目前尚无充分证据表明UPPP治疗睡眠呼吸障碍疗效优于其它治疗,也无证据表明哪种治疗方式疗效最佳.由于本研究纳入的文献语种仅限于中文及英文,可能会漏掉一些有价值的文献;所纳入的文献数量少、质量低,使论证强度受到一定限制,在今后的临床工作中有必要进行大样本含量,高质量的临床随机对照研究.

Uvulopalatopharyngoplasty Treatment in Snoring and Obstructive Sleep Aponea Syndrome:A Systematic Review

Objective To assess the clinical effectiveness and safety of uvulopalatopharyngoplasty (UPPP) in the treatment of snoring and obstructive sleep aponea syndrome (OSAS).Methods MEDLINE(1966 2005), EMBASE (19842005), The Cochrane Library ( Issue 1, 2005), CBM (19792005), CNKI(19942005), VIP( 19892005), CMCC (19942005) ,Wanfang Database and Internet were searched in English and Chinese versions. Randomized controlled trials(RCTs), quasi-randomized controlled trials and prospective cohort studies were included. Study quality was evaluated by two researchers independently. RevMan4.2.7 was used for meta-analysis. Results Twelve studies were included, of which 5 were RCTs, 7 were prospective cohort studies. Compared with dental appliance(DA), PSG(polysomnography) changes of DA group were larger than UPPP group, but patients of UPPP group had better quality of life and compliance.Comparing UPPP with LAUP(laser-assisted uvulopalatpharyngoplasty) and RFTVR(radiofrequency tissue volume reduction), the postoperative pain of the latter two was less than UPPP. About complications, UPPP and LAUP had no difference except for nasal reflux at 1 week after operation, there was no statistical difference between UPPP and RFTVR. There was no study to compare the PSG change among the three groups. Comparing UPPP with CPAP(continuous positive airway pressure), PSG changes were larger in CPAP. Conclusions At present, there is no evidence to assure that UPPP is better than other treatments for snoring and OSAS or to suggest which type of surgery is most effective. The literature search is restricted to the publications of English and Chinese language, which may have resulted in missing some studies; the evidence is still weak due to the poor quality and a small number of included studies. There is an urgent need for high quality RCTs to be carried out.
