Effect comparison of the focused ultrasound and radiofrequency ablation under nasal endoscope in the treatment of allergic rhinitis

Objective:To observe the effects of high intensity focused ultrasound and low temperature radiofrequency ablation under nasal endoscope in the treatment of allergic rhinitis.Methods:One hundred and seventy-nine patients with allergic rhinitis were divided into the focused ultrasound group(FU group,84 cases) and radiofrequency ablation group(RFA group,95 cases).The symptoms and signs in all patients were recorded and scored before and after treatment,and the therapeutic effects between two groups were analyzed.Results:The score of the symptoms and signs in FU group before treatment(10.84±2.26) was significantly higher than that after 12 months of treatment(4.65±1.76)(P<0.01).The score of the symptoms and signs in RFA group before treatment(10.02±2.05) was significantly higher than that after 12 months of treatment(5.32±1.37)(P<0.01).Two groups were followed up for 1 year.The total effective rates in FU and RFA group were 86.9% and 73.7%,respectively,the difference of which was statistically significant(P<0.05).Conclusions:The high intensity focused ultrasound and radiofrequency ablation are the effective physical methods in treating allergic rhinitis,especially within 1 year.The treatment of allergic rhinitis with focused ultrasound is less trauma,can be repeated,and its curative effect is more durable after 1 year.
