Conclusion: An inflammatory swelling in the uvula and nose due to vibration might be a contributing factor in snoring. The presence of corticosteroid receptors in the uvula indicates the possibility for treatment with local steroids. Use of mometasone furoate (MF) for 3 months reduced snoring and related symptoms in some patients.
Objective: To investigate the effect of a nasal steroid, MF, on snoring and related discomfort.
Subjects and methods: In the first part of the study, uvular and nasal biopsies from six patients with social snoring were examined using immunohistochemistry to evaluate whether corticosteroid receptors were present. Then 100 snoring patients were invited to participate in the second part of the study. In all, 72 men and 22 women with a mean age of 47 years and BMI 27 answered a questionnaire about symptoms, had ENT status assessed and reported sleep and related variables for a 7 day period. After randomization to placebo or MF, they used a nasal spray for 3 months at a dosage of 200 microg. Thereafter the procedure was repeated.
Results: Corticosteroid receptors were present in the mucous membranes and around the blood vessels in all uvulas examined. A total of 84 patients were evaluated. No decrease in 'mean snoring score' was seen. Daytime sleepiness showed a slight improvement in the MF group and partners were less disturbed. Minor side effects were equal for both groups.
