The Efficacy Of Rhinophototherapy Compared To Intranasal Corticosteroids On The Nasal Mucosa

There are several specific objectives for this study: 1. To subjectively and objectively compare the efficacy of intranasal phototherapy and intranasal corticosteroids in treating allergic rhinitis via assessment of rhinomanometry, peak nasal inspiratory flow (PNIF) and visual analogue scale(VAS) score. 2. To determine mucosal inflammatory cells changes (eosinophils, neutrophils, mast cells) between patients treated with intranasal rhinophototherapy and intranasal corticosteroids. 3. To determine mucosal damage (fibrosis, mucosal ulceration , squamous metaplasia) between patients treated with intranasal rhinophototherapy and intranasal corticosteroids. Patients who meet the criteria to join the study will be randomized in a single-blinded manner(investigator). Patients will be given information about the study and consent form, patients will be randomized to 2 treatment group (rhinophototherapy and Nasonex nasal spray). Patients will be evaluated before and after treatment in two weeks time.
