title: [Significance of AG in OSAHS operation treatment guidance and evaluation of postoperative efficacy].
abstract: OBJECTIVE
  Apneagraph can be used to discuss which the best operation scheme is for OSAHS. Effects of uvulopalatopharyngoplasty can be assessed by Apneagraph in obstructive sleep apnea hypopnea syndrome (OSAHS) patients.
  
  
  METHODS
  Fifty-six patients with OSAHS received the modified UPPP operation were randomly selected in our hospital. The AG and PSG were applied for diagnosis and evaluation of operation effects. The sleepiness state was assessed by ESS (Epworth sleepiness scale) 6 months after the surgery, compared with the preoperative ESS scores using attest for statistical analysis. We used the SPSS19.0 software to carry our data analysis.
  
  
  RESULTS
  After 6 months, the evaluation of postoperative efficacy came out to be completely controlled in 42 cases (75%), significantly effective in 14 cases (25%), and uncured in 0 cases. Correlation between the transpalatal obstruction proportion and the AHI reduction percentage was significantly positive (r = 0.667). There were 38 patients with oropharynx obstruction percentage more than 73.35% presented completely controlled in 34 cases (89.47%), significantly effective in 4 cases (10.33%), and uncured in 0 cases.
  
  
  CONCLUSIONS
  AG has the dual functions of analyzing sleep-related respiratory disturbance events and determining upper airway obstruction sites. AG application in the postoperative evaluation of modified uppp has significantly objective guide significance. The modified UPPP for treatment of OSAHS can improve the operation effect. Patients with oropharynx obstruction percentage more than 73.5% don't need to receive the operation for treatment of retroglottal region.
