Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Nasal Symptom Score

    In accordance with the recommendations from the European Academy of Allergy and Clinical Immunology (EAACI), the primary assessment indicators for allergic rhinitis include scoring for four nasal symptoms (itchy nose, sneezing, runny nose, nasal congestion) and two ocular symptoms (itchy/sensation of foreign body/redness of eyes, tearing). Evaluation is conducted using the "four-point scale" and a Visual Analogue Score (VAS) to assess the individual symptoms and/or the overall nasal and ocular symptoms before, during, and after treatment. 0 points: Asymptomatic 1. point: Mild symptoms (Signs/symptoms noticeable but barely bothersome; easily tolerated) 2. points: Moderate symptoms (Bothersome symptoms/signs that are clearly noticeable but tolerable) 3. points: Severe symptoms (Intolerable, causing interference with daily activities and/or sleep)

    1 month, 3 months, 6 months, 1 year, and 2 years post-treatment

  • daily medication score

    The recorded information includes the medication name, method of use, and dosage. Symptomatic medication scoring is based on the patient's symptomatic medication usage, assessing clinical effectiveness. The scoring method employs a "three-step" approach: one point is assigned for the use of nasal, ocular, oral, or topical antihistamines; two points for nasal corticosteroids (or combined with antihistamines); and three points for oral corticosteroids (or combined with nasal steroids/antihistamines). 1. point: Oral and/or topical antihistamines (nasal or ocular) 2. points: Nasal corticosteroids (or combination with antihistamines) 3. points: Oral corticosteroids (or combination with nasal corticosteroids/antihistamines)

    1 month, 3 months, 6 months, 1 year, and 2 years post-treatment

Study Arms (2)

High-intensity focused ultrasound (HIFU)

ACTIVE COMPARATOR

The High-Intensity Focused Ultrasound (HIFU) knife, also known as the High-Intensity Focused Ultrasound Tumor Treatment System or HIFU ablation therapy, abbreviated as the HIFU knife, is a non-invasive and non-intrusive tumor treatment method utilizing "high-intensity focused ultrasound technology." This technology was successfully developed by the Ultrasound Medical Engineering Research Institute of Chongqing Medical University in 1997.

Procedure: High-intensity focused ultrasound (HIFU)

Placebo

PLACEBO COMPARATOR

For patients in the Placebo treatment group, treatment is provided based on the severity of their symptoms, following the protocols outlined in the Allergic Rhinitis (AR) diagnosis and treatment guidelines. Patients are administered intranasal corticosteroids, oral antihistamines, oral leukotriene receptor antagonists, and intranasal antihistamines, as appropriate, in accordance with the severity of their symptoms.

Drug: intranasal corticosteroids, oral antihistamines, oral leukotriene receptor antagonists, and intranasal antihistamines

Interventions

Ultrasound is a type of mechanical vibrational wave capable of penetrating living tissues without causing harm to the tissue. As a non-invasive physical modality, ultrasound boasts advantages such as non-invasive safety, excellent directional propagation, strong penetration capability, and optimal focusing effects. It can induce a series of structural and functional changes in tissue cells through actions like cavitation, mechanical force vibration, and heat generation, leading to corresponding clinical effects. Clinical studies have demonstrated that focused ultrasound not only improves symptoms of allergic rhinitis (AR) but also holds certain advantages in preserving the structural and functional integrity of the nasal mucosa.
