Allergic rhinitis (AR) is a common condition, with nearly 300 million affected individuals in China, significantly impacting the quality of life. Despite standardized drug treatments, approximately 20% of AR patients experience inadequate control and require surgical intervention. AR manifests as nasal itching, sneezing, clear nasal discharge, nasal congestion, primarily associated with inflammation-induced hypertrophy of nasal turbinates and a heightened neurogenic state of the nasal mucosa. Surgical treatment focuses on reducing hypertrophy of nasal turbinates and desensitizing neurogenic hyperreactivity.High-intensity focused ultrasound (HIFU), as a minimally invasive therapeutic modality in AR, is still in its early stages of application and requires further multicenter clinical studies and widespread adoption. This project collaborates with six established institutions proficient in ultrasound treatment for AR. It aims to conduct a prospective multicenter observational study and subsequent dissemination, emphasizing the application of reduction of hypertrophy and desensitization in AR.Through standardized case selection, subjective and objective measures such as subjective symptom scores, quality of life assessments, nasal reflex, and nasal resistance tests before and after treatment will be employed to evaluate the effectiveness and safety of HIFU in reducing hypertrophy and desensitizing aspects of AR. Simultaneously, building on our established Otolaryngology Head and Neck Surgery Alliance and Southwest Allergy Alliance, the research results will be promoted through lectures, hands-on guidance, training sessions, academic conferences, and other means to facilitate the application of HIFU in AR and benefit a larger population of AR patients.
