Background Obstructive sleep apnoea is a serious medical condition of increasing prevalence that has a multitude of treatment modalities. The aim of this study was to review the results of patients treated with mandibular advancement splints in the Oral and Maxillofacial Surgery Unit of South Australia to inform ongoing practice in this area. Methods The casenotes of patients who received a splint for obstructive sleep apnoea between January 2008 and June 2014 were audited. Data collection included referral and demographic details, sleep study results, splint type and follow‐up details. Results Three hundred and four patients were identified as having been provided a mandibular advancement splint for obstructive sleep apnoea, of which 82 had diagnostic and splint‐in‐situ sleep studies available for comparison. It was observed that 27 had clinically significant objective improvement, 40 had no clinically significant change and 15 had clinically worse OSA following MAS therapy. Mean reductions in Apnoea‐Hypopnoea Index and Respiratory Disturbance Index were eight events (27%) and 13 events (33%) per hour respectively with treatment. Conclusions Based on this study, mandibular advancement splint therapy is a viable treatment for a subset of patients with obstructive sleep apnoea. Protocol driven, multi‐disciplinary care with auditing of results is recommended.
