Background: In this study, the outcome of uvulopalatopharyngoplasty combined with radiofrequency of the tongue base reduction was investigated in patients with obstructive sleep apnea syndrome with both palatal and retrolingual obstruction.
Patients and methods: A retrospective cohort study was performed in patients with mild to severe OSAS. Forty-two patients with OSAS who underwent RFTBR combined with UPPP took part in this study Surgical success was defined as AHI<20 with more than 50% reduction in AHI and a response rate considered as reduction of AHI between 20 and 50%. The overall response rate was defined as more than 20% reduction in AHI.
Results: BMI was not changed significantly before (28.64±5.14kg/m2) and after surgery (28.41±5.21kg/m2). Mean AHI decreased from 49±7.23/hour to 12.63±5.72/hour (p<0.05) and mean reduction rate of AHI was 74.43±7.25% for all 42 patients, 78.9±5.14% in patients with Friedman’s anatomical stage II and 69.9±7.13% in patients with stage III (p<0.05 for both). The mean snoring sound decreased significantly from 3.35±0.67 to 1.25±1.03 at the 6th post-operative month (p<0.05). The mean value for ESS was significantly decreased from 12.6±2.17 to 5.3±1.217 at the 6th post-operative month (p<0.05).
Conclusion: Single-session RFTBR combined with uvulopalatalpharyngoplasty is an effective treatment for reducing symptoms and AHI in OSAS patients with multilevel obstruction.
