Clinical observation of treating allergic rhinitis with focused ultrasound under nasal endoscope

Objective:To observe the short-term therapeutic effect of focused ultrasound in treating allergic rhinitis under nasal endoscope.Method:One hundred and seventeen patients with allergic rhinitis were treated by the CZB ultrasound therapeutic system which was developed and produced by Chongqing Haifu (HIFU) Technology Co. Ltd., Chongqing China. It was used to scan inferior nasal concha and the anterosuperior part of nasal septum under nasal endoscopy. The therapeutic effect was evaluated by clinical symptoms controlled counting-scores, according to the Chinese Lan zhou principle of treatment and recommendation program for allergic rhinitis (2004).Result:The excellent effective rate was 44/117 cases (37.6%), effective rate was 49/117 cases (41.9%), ineffective rate was 24/117 cases (20.5%), and the total effective rate was 79.5% after 12 months follow up.Conclusion:The focused ultrasound is convenient, safe, repetitive and effective in treating allergic rhinitis under nasal endoscope. The long-term therapeutic effect remains to be further studied.
