OBJECTIVE: To treat OSAHS with radiofrequency ablation and evaluate the effect. METHOD: Thirty four patients with mild and median OSAHS were treated with functional endoscopic sinu surgery, UPPP and RFA. The follow up time was 1 year. PSG was used for diagnosis and evaluation of pre- and post-operation. RESULT: AHI of 34 patients reduced from (20.74 +/- 12.23)/h to (12.23 +/- 8.31)/h (P < 0.01). Effective rate was 85.29%. CONCLUSION: RFA is an effective, safe and simple assitant therapy for OSAHS.
