Bimaxillary osteotomy for obstructive sleep apnoea


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.
