title: [Clinical study on efficacy of nasal surgical expansion as a basic operation in treatment of patients with OSAHS].
abstract: OBJECTIVE
  To observe the clinical effect of nasal surgical expansion as basical surgical treatment of patients with OSAHS.
  
  
  METHODS
  A total of 320 patients with OSAHS were retrospectively analyzed. The patient was diagnosed by PSG. The electronic nasopharyngolarygnoscope exam airway CT, and MRI were applied to determining the nasal plane block. According to the concrete reasons, the nasal endoscopic nasal septum corrective surgery and open surgery were carried out, respectively. Nasal sinus neoplasm resection of off shoring, inferior turbinate fracture surgery or inferior turbinate back-end 1/3 line expansion and low temperature plasma ablation of nasal surgery, respectively. Pittsburgh sleep quality index (PSQI), snore outcome survey (SOS), epworth sleepiness score (ESS), the lowest arterial oxygen saturation (LSaO2) and AHI, time and ratio of slow wave sleep (SWS) stage and rapid eye movement (REM) stage were applied to comparing the curative effect between pre-operation and post-operation periods.
  
  
  RESULTS
  Snoring, sleep apnea, subjective mental symptoms of all patients with OSAHS were improved after operation; PSQI, SOS and ESS score were improved compared to pretreatment (P < 0.05); according to the 2009 OSAHS diagnosis and curative effect evaluation standard, 38 cases cured, 189 cases had obvious effect, 93 cases effective, and the total effective rate was 100%; there was statistical difference between the pre-operative period and 6 months post-operative in PSQI, SOS and ESS, LSaO2, AHI and proportion of REM (P < 0.05); sleep structure was improved, time and proportion of SWS were increased after the operation (P < 0.05).
  
  
  CONCLUSIONS
  Solving the problem of nasal airway obstruction is the first step in surgical treatment of patients with OSAHS.
