Chronic sinusitis, or chronic rhinosinusitis, is an inflammatory condition defined by symptomatic inflammation of the paranasal sinuses lasting longer than 3 months. Common presenting symptoms include nasal obstruction, facial pressure or fullness, nasal discharge (anterior or posterior), and olfactory loss. Furthermore, chronic sinusitis is associated with reductions in patient quality of life (QOL), sleep quality, and daily productivity.~It has been suggested that low-level laser can be used in treating chronic sinusitis but there are limited studies about its usage.~HYPOTHESES:~There is no statistically significant effect of laser therapy on headache, fatigue, or CT finding in patients with chronic sinusitis.
This study aimed to evaluate the efficacy of low-level laser therapy (LLLT) for Chronic sinusitis in a randomized, double-blind, placebo-controlled trial.
