Rhinophototherapy in chronic rhinosinusitis: a double blind randomized placebo-controlled trial

Abstract

BACKGROUND: This study evaluated the efficacy of rhinophototherapy in patients with chronic rhinosinusitis (CRS) without nasal polyps. METHOD: In this randomized double-blind, placebo-controlled trial, CRS patients (n=50) received either mixed visible and ultraviolet (UVA and UVB) light source application (mUV/VIS) or visible light alone that served as placebo. Both groups were treated for 3 weeks. RESULTS: Results in the rhinophototherapy and placebo group were not significantly different and failed to reduce patient-reported outcomes measures (Rhinosinusits Disability Index, Visual Analogic Scale of symptom severity) and objective scores (rhinomanometry, olfactory thresholds, nasal Nitic Oxide concentrations), immediately and one month after treatment. CONCLUSIONS: The present data suggest that rhinophototherapy is not an efficient treatment for chronic rhinosinusitis without nasal polyps.
