Abstract：ObjectiveTo compare the clinical efficacy and postoperative adverse reactions between the focused ultra-sound and radiofrequency ablation in the treatment of allergic rhinitis.Methods100 cases treated by radiofrequency ablation and 59 cases treated by focused ultrasound were in-cluded in this study. Scoring method was used to evaluate the efficacy and counting method was used to evaluate postoper-ative adverse reactions.ResultsThere were no significant differences in age(t=0.63,P=0.15),gender(χ2=0.21, P=0.65)and nationality(χ2=5.43,P=0.25)between the two groups. During postoperative follow-up 12 months,the effi-ciency of focused ultrasound group were 94.92%,98.31%, and 100.00% in 1 week,1 month and 12 months respective-ly,while the efficiency of radiofrequency ablation group were 99.00%,99.00% in and 97.00% . There were no differences in the efficiency between two groups. Postoperative adverse reactions:Focused ultrasound group were better than radiof-requency ablation group in edema,secretions pseudomem-brane and dry scab postoperative 1 month and in nasal cavity bleeding and dry scab postoperative 1 month.Conclusion Both focused ultrasound treatment and radiofrequency ablation treatment were equally effective in the treating allergic rhinitis. Focused ultrasound was better than radiofrequency ablation treatment in postoperative adverse reactions.
