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

Area of Science:

• Otolaryngology
• Photomedicine

Background:

• Chronic rhinosinusitis (CRS) without nasal polyps is a common condition.
• Evaluating novel therapeutic approaches for CRS is essential.

Purpose of the Study:

• To assess the efficacy of rhinophototherapy in treating CRS without nasal polyps.
• To compare a mixed visible and ultraviolet (mUV/VIS) light therapy against a placebo.

Main Methods:

• A randomized, double-blind, placebo-controlled trial was conducted.
• Fifty CRS patients received either mUV/VIS or visible light (placebo) for three weeks.
• Outcomes were measured immediately and one month post-treatment.

Main Results:

• No significant differences were observed between the rhinophototherapy and placebo groups.
• Patient-reported outcomes (disability index, symptom severity) showed no improvement.
• Objective measures (rhinomanometry, olfaction, nitric oxide) also remained unchanged.

Conclusions:

• Rhinophototherapy is not an effective treatment for chronic rhinosinusitis without nasal polyps.
• Further research may be needed to explore alternative phototherapy parameters or patient subgroups.
