Objective：to study the efficacy，safety and compliance of surgical operation combined with nasal airway radiofrequency ab－lation in the treatment of light-moderate obstructive sleep apnea hypopnea syndrome complicated with chronic nasal obstruction and to confirm the clinical value of the treatment. Methods：Seventeen-six patients with light-moderate obstructive sleep apnea hypopnea syndrome from March 2012 to March 2013 were enrolled as research objects and were randomly divided into observation group（n=38） and control group（n=38）. Patients in observation group were treated by nasal operation combined with upper airway radiofrequency ablation therapy while those in control group were treated by routine nasal operation. Drowsiness，snoring subjects，blood oxygen sat－uration and other comparative data were compared before and after the treatment. Data of curative effect，complication and compliance were statistically analyzed. Results：There was no significant difference between the two groups in sleepiness，snoring and oxygen sat－uration before the treatment（P=0.062，P=0.058，P=0.052）. After the treatment，symptoms of subjects were improved obviously，with significant differences（P=0.042，P=0.044，P=0.040）. Total effective rate of observation group was 78.9%，higher than that of 57.9% in control group，with significant differences（P=0.028）. The complication incidence，compliance rate and recurrence rate were 21.1%，92.1% and 15.8% in observation group，better than those of 44.7%，78.9%，36.8% in control group，with significant differences（P=0.028，P=0.035，P=0.032）. Conclusion：Surgical operation combined with nasal airway radiofrequency ablation is effective and safe in the treatment of light-moderate obstructive sleep apnea hypopnea syndrome complicated with chronic nasal obstruction，therefore have remarkable clinical value.
