Allergen immunotherapy (AIT) has been shown to be effective in the treatment of not only the symptoms, but also the underlying causes of the disease. Moreover, AIT has a preventative role against new sensitizations and development of asthma in AR patients. Hence AIT is recommended as an integrated part of an allergy management strategy in the treatment of AR. Over the development of one century, AIT has been delivered by various routes. Among them, subcutaneous immunotherapy (SCIT) has been currently widely used in clinical practice.\n\nHouse dust mite (HDM) has been reported to be the most common sensitizing allergen in China. Nasal obstruction is the common complaint in HDM-sensitized AR and prompts patients to seek medical help. It has been proved that HDM-SCIT showed favourable efficacy in treating persistent AR. However, HDM-SCIT recommends 3 years of subcutaneous injection and requires good adherence to guarantee the efficacy. Later onset of nasal obstruction alleviation might reduce the adherence of HDM-SCIT.\n\nRadiofrequency ablation of bilateral inferior turbinate can relieve nasal obstruction within a short time after operation. It is hypothesized that, in HDM-AR patients with severe nasal obstruction, bilateral inferior turbinate surgery followed by HDM-SCIT will obtain quick-onset of good nasal ventilation and improve AIT adherence.\n\nThe overall objective of the proposed randomized controlled trial is to test whether radiofrequency ablation of bilateral inferior turbinate followed by subcutaneous immunotherapy will improve nasal obstruction among patients with house dust mite sensitized allergic rhinitis (HDM-AR) compared to subcutaneous immunotherapy (SCIT) only during the 4-month build-up phase as well as the 36-month full phase of SCIT.",[65],"Allergic Rhinitis Due to House Dust Mite","NOT_YET_RECRUITING","2022-08-19",{"date":69,"type":70},"2022-08-22","ACTUAL",{"date":72,"type":59},"2022-10-01",{"date":74,"type":59},"2026-12-31",{"name":5,"class":6}]
