title: A Prospective Study of the Surgical Outcome of Simple Uvulopalatopharyngoplasty (UPPP), UPPP Combined With Genioglossus Advancement or Tongue Base Advancement for Obstructive Sleep Apnea Hypopnea Syndrome Patients With Multilevel Obstruction.
abstract: OBJECTIVE
  To investigate the surgical outcomes of different uvulopalatopharyngoplasty (UPPP).
  
  
  METHODS
  All subjects underwent overnight polysomnography and were evaluated using the Epworth sleepiness scale (ESS), the Quebec sleep questionnaire and the snoring scale at the baseline and 3 and 12 months following operation. The primary endpoint was the overall effective rate representing the sum of the surgical success rate and effective rate.
  
  
  RESULTS
  The overall effective rate at 12 months post surgery was 55.6% for simple UPPP, 95.8% for UPPP+GA, and 92.3% for UPPP+TBA. The surgical success rate at 3 and 12 months postoperation for UPPP+GA or UPPP+TBA was significantly higher than simple UPPP (P<0.05). Marked improvement was observed in all patients in the snoring scale score and the ESS score 3 and 12 months following surgery compared to the baseline (P<0.05 in all).
  
  
  CONCLUSIONS
  UPPP, UPPP+GA, and UPPP+TBA are all effective in improving the surgical outcome of obstructive sleep apnea hypopnea syndrome (OSAHS) patients with multilevel obstruction. UPPP+TBA appears to be the most effective in treating OSAHS patients.
