Abstract: Objective: To determine the efficacy of temperature－controlled radio-frequency ablation (TCFR) for obstructive sleep apnea hypopnea syndrome (OSAHS) in adult. Methods: Some objective and subjective indexes of fifty patients with OSAHS were determined before and after TCRF treatment. A full-night polysomnography examination was performed on all patients. The Epworth sleepiness scale (ESS) and the Calgary sleep apnea quality of life index (SAQLI) were assessed before and six months after operation. Results: Of them, 19 cases were cured, 18 cases were significantly improved, 16 cases were improved, and 7 cases were not improved. The mean apnea hypopnea index （AHI） decreased from（45.2+20.5）/h to (26.5+30.2)/h and the mean lowest arterial oxygen saturation (LSaO2) increased from(0.7+0.1) to (0.8+0.1). The ESS decreased from (9.4+5.2) to (4.0+3.3) and the SAQLI increased from(3.8+1.0) to (4.8+1.1). All the above differences were significant (P＜0.05). Conclusion: TCFR is an effective treatment for OSAHS and can improve the health-related quality of life.
