[Investigation of reoperation after failure of UPPP]
1Department of ENT, Dalian Municipal Central Hospital, Dalian, China.
Objective:
To explore the surgical ways of reoperation of the UPPP.
Method:
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.
Result:
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.
Conclusion:
The shortcomings of UPPP could be made up with ablation, and the ablation could help the UPPP more minimal damage and effective therapy.
