Research On The Clinical Efficacy Of Treating Allergic Rhinitis With High Intensity Focused Ultrasound

Objective:To research the clinical effect of allergic rhinitis (AR) with high intensity focus ultrasound (HIFU).Methods:A total of120patients were selected as observation objects and divided into two parts by the nasal structure abnormalities. Among the part one, The40cases of normal nasal anatomic structure were divided into two groups. The HIFU group1(20cases) was receiving the High-intensity focused ultrasound under nasal endoscope. In the drug group (20cases), the patients received the treatment of drug. In addition, the80cases of AR complicated with nasal septum deviation (NSD) and inferior turbinate hypertrophy were allocated to part two. They were divided into two groups:the HIFU group2(40cases) was only treated by High-intensity focused ultrasound; the operation group (40cases) was treated by inferior turbinate out fracture, resection nasal septum deviation, and HIFU. All of the patients were followed-up with3months. Results: After3mouth follow up, in the treatment of14days, the total symptom score in HIFU group1were2.90±1.20, in drug group were3.25±1.37, and there was significant difference between them (P<0.05).In the HIFU group2, the total symptom score were4.65±1.72.In the operation group B were1.05±1.35.There was significance difference between two groups (P<0.05). Conclusion:For patients of AR with normal nasal anatomic structure, HIFU has an obvious short-term effect than drug. However, if the patients with abnormal nasal anatomic structure, the treatment of inferior turbinate out fracture, resection nasal septum deviation combine with HIFU has an obvious short-term effect. HIFU is a safe and noninvasive method to treatment of AR.
