Objective To observe the shortterm therapeutic effect of focused ultrasound for the treatment of allergic rhinitis under nasal endoscope. Methods Fifty patients with allergic rhinitis were treated with the CZB ultrasound therapeutic system under nasal endoscope. The targets were inferior nasal concha and the anterosuperior part of nasal septum. The therapeutic effect was evaluated by clinical symptoms controlled countingscores, according to the Chinese Wuyishan principle of treatment and recommendation program for allergic rhinitis (2009). Results After postoperative followup for 6 month, the excellent effective rate was 36% (18/50), effective rate was 40% (20/50), ineffective rate was 24% (12/50), with a total effective rate of 76%. Conclusion The focused ultrasound is convenient, safe, repetitive and effective for the treatment of allergic rhinitis under nasal endoscope. The longterm therapeutic effect remains to be further studied.
