title: [The effect of the size of tonsil on uvulopalatopharyngoplasty].
abstract: OBJECTIVE
  To investigate how the size of tonsil affects the curative effect of patients with obstructive sleep apnea hypopnea syndrome (OSAHS) treated with Uvulopalatopharyngoplasty (UPPP).
  
  
  METHODS
  Fifty-four cases with OSAHS treated with UPPP in our department were analyzed retrospectively. The polysomnography (PSG) was examined again one years or longer after operation.
  
  
  RESULTS
  There was no statistical difference between different tonsil size groups in age, apnea-hypopnea index (AHI), body mass index (BMI) and the lowest Pulse Oxygen Saturation (lowest SpO2) before operation. But there was a statistical difference in curative effect after operation between groups. The lowest SpO2 raised obviously in groups with bigger tonsils. In serious OSAHS group, there was a statistical difference in the composing of tonsil size grade in different curative effect groups.
  
  
  CONCLUSIONS
  Patients with bigger size of tonsil will receive a better result after UPPP while the lowest SpO2 will be improved more prominent. To serious OSAHS, we should treat them individually.
