To gain insight into postoperative results of bimaxillary osteotomy in patients with obstructive sleep apnoea (OSA).
Retrospective patient series.
All patients with OSA who had undergone a bimaxillary osteotomy in the Amphia Hospital in Breda in the Netherlands in the past 4 years were eligible for inclusion. The primary outcome measures were the apnoea-hypopnoea index (AHI), a decrease in symptoms and the success of the operation.
In the past 4 years, 22 patients with OSA underwent a bimaxillary osteotomy in the Amphia Hospital in Breda. We further analysed data from 18 patients. All patients had a normal to moderately elevated BMI. 94.1% had a complete absence or a marked decline in symptoms postoperatively. In 23.5% the cure was complete (AHI < 5/h) and treatment was successful in 52.9% of the patients (> 50% reduction in AHI and AHI < 20/h). The average AHI decreased from 38/h preoperatively to 11/h postoperatively.
Bimaxillary osteotomy is currently often regarded as a final treatment option for patients with OSA. Even in these patients with a relatively complex condition the results of the operation are relatively good. For treatment providers it is important to recognise patients who might benefit from a bimaxillary osteotomy, such as patients with OSA and retrognathia.
