title: [Meta analysis of nasal surgery alone for obstructive sleep apnea hypopnea syndrome].
abstract: OBJECTIVE
  To investigate the effect of nasal surgery alone for OSAHS using Meta-analysis.
  
  
  METHODS
  The published articles were searched from PubMed, Chinese Biomedical Literature CD-ROM databases, China Academic Journals Full-text database. The quality of the searched original studies were assessed and the outcomes with the requirements were analyzed.
  
  
  RESULTS
  Nineteen articles and 621 cases were finally included, including 15 English literatures and 4 Chinese literatures. The results of Meta analysis showed that: (1)The weighted mean between pre-and postoperative AHI was no significantly difference [weighted mean difference (WMD) = 0. 11, 95% CI (-0. 02,0. 23), P>0. 05]. (2) The nasal surgery alone significantly reduced theEpworth sleepiness scale scores in thirteen studies [WMD=0. 94,95% CI (0. 62,1. 26), P<. 01].
  
  
  CONCLUSIONS
  The meta-analyses show that nasal surgery alone can effectively improve the subjective clinical symptoms of patients with OSAHS. However, nasal surgery alone has a limited efficacy in treating OSAHS.
