Effect of Red Light Rhinophototherapy on Nasal Patency in Patients With Allergic Rhinitis

This study focuses on individuals experiencing moderate to severe symptoms of allergic rhinitis (AR), a condition characterized by nasal congestion, runny nose, itchy nose, or sneezing. The goal is to evaluate the effect of red light rhinophototherapy (RLRPT) on nasal patency in these patients. AR is diagnosed based on patient history, physical examination, and a specific IgE test against common allergens. Patients with a symptom score of 4 or more are enrolled, excluding those under 20, with severe nasal septum, rhinosinusitis, nasal polyposis, immunodeficiency, previous sinus surgery, recent upper respiratory tract infection, or oral corticosteroid use. Participants are randomly divided into two groups. The study group receives one session of RLRPT, delivered via a device called the Transverse Many Channels Laser Instrument. This involves placing light-emitting nasal probes into both nostrils for 15 minutes. After the treatment, patients rest for 30 minutes and then report on the severity of their symptoms and any changes. They also receive medical treatment involving an intranasal steroid and an oral antihistamine. Follow-up questions are asked 2 days later. The control group receives only the medical treatment, with follow-up questions asked 2 days later. The study measures nasal patency using active anterior rhinomanometry and acoustic rhinometry.
