Nasal steroids in snorers can decrease snoring frequency: a randomized placebo-controlled crossover trial.

Although it is anecdotally known that nasal obstruction is associated with snoring, it remains unknown whether the application of nasal steroids could decrease oral/oro-nasal breathing and increase nasal breathing, and subsequently decrease snoring indices. This study evaluated the effect of nasal budesonide on breathing route pattern and snoring. Twenty-four snorers were enrolled in a randomized, double-blind, crossover trial of 1-week treatment with nasal budesonide compared with 1-week intervention with nasal placebo.
