Oral appliances for the management of severe snoring: a randomized controlled trial

Show Summary Details

Preview

The aim of this randomized controlled trial was to assess the effectiveness of a mandibular advancement appliance (MAA) in managing severe snoring. Twenty‐eight adults with severe snoring and normal overnight oximetry were recruited from sleep disorder clinics. A maxillary placebo appliance and a MAA were worn by each subject for a period of 4–6 weeks each. Questionnaires at baseline and after each appliance period assessed bed partners' reports of snoring severity (loudness and number of nights per week), and patients' records of daytime sleepiness. Twenty‐five subjects completed the entire trial.

The MAA was significantly more effective than the placebo in reducing the frequency and loudness of snoring, the reported daytime sleepiness and the frequency of morning tiredness. Excessive salivation was the most commonly reported complication. It was concluded that the custom‐made MAA was significantly more effective than the placebo in managing the main symptoms of severe snoring. However, not all subjects' partners reported an improvement with the MAA, with 84 per cent reporting a reduction in snoring loudness and 76 per cent reporting snoring on fewer nights per week.
