title: [Investigation of reoperation after failure of UPPP].
abstract: OBJECTIVE
  To explore the surgical ways of reoperation of the UPPP.
  
  
  METHODS
  Fifteen failed cases of OSAHS after UPPP were reviewed and analyzed. The reoperations were performed with modified laser assistant, ablation assistant UPPP combining ablation of tongue base. The follow-up was done after 1 year.
  
  
  RESULTS
  The AHI decreased from (38.56 +/- 11.23)/h to (4.87 +/- 1.59)/h and the lowest SpO2 increased from (61.5 +/- 8.5)% to (79.9 +/- 9.7)% of the patients. The statistical difference was significant (P<0.01) in 1 year after the reoperation. The total validity ratio was 100% and the recovery rate was 96%. No complications happened.
  
  
  CONCLUSIONS
  The shortcomings of UPPP could be made up with ablation, and the ablation could help the UPPP more minimal damage and effective therapy.
