Objective:To observe the therapeutic effect of high intensity focused ultrasound in treating allergic rhinitis.Methods:Two hundred and twenty patients with allergic rhinitis

according to the Chinese Lanzhou diagnostic criteria of allergic rhinitis(2004)

were treated by the CZB ultrasound therapeutic system which was developed and produced by Chongqing Haifu(HIFU) Technology Co.

Ltd

Chongqing

China.The scanned area covered bilateral inferior turbinate

the front middle turbinate

agger nasi

and the front nasal septum.The therapeutic effect was evaluated by clinical symptoms being scored

according to the Chinese Lanzhou principle of treatment and recommendation program for allergic rhinitis(2004).Results:Patients were followed up after 3 months

6 months

12 months

and 18 months for efficacy evaluation.The excellent effective rate was 68.2;less effective rate was 23.6;ineffective rate was 8.2%

and the total effective rate was 91.8% after a 3 months’ follow up.The excellent effective rate was 60.6%;less effective rate was 24.9%;ineffective rate was 14.5%

and the total effective rate was 85.5% after a 6 months’ follow up.The excellent effective rate was 55.1%;less effective rate was 17.8%;ineffective rate was 27.1%

and the total effective rate was 72.9% after a 12 months’ follow up.The excellent effective rate was 52.9%;less effective rate was 20.6%;ineffective rate was 26.5%

and the total effective rate was 73.5% after a 18 months’ follow up.Conclusion:The high intensity focused ultrasound is effective

non-invasive

and repeatable in treating allergic rhinitis.
