Temperature-controlled radio-frequency ablation in treatment of obstructive sleep apnea hypopnea syndrome

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(P0.05).Conclusion: TCFR is an effective treatment for OSAHS and can improve the health-related quality of life.
