[Outcomes of bimaxillary osteotomy for obstructive sleep apnoea].

Bimaxillary osteotomy is skeletal surgery for the treatment of obstructive sleep apnoea. Several studies have shown bimaxillary osteotomy to significantly improve respiratory parameters - including the apnoea-hypopnoea index, zero oxygen saturation, and the respiratory disturbance index - in the short and the long term. Additionally, research has shown that bimaxillary osteotomy contributes to a reduction in systemic blood pressure and to improvements in sleep architecture and neurocognitive functions. Subjectively, a significant proportion of patients report a decrease in daytime sleepiness, an improvement in sleep-related and general quality of life, and a positive change in facial aesthetics. Potential disadvantages of the procedure include temporary or permanent sensory disorders, a temporary reduction in oral health-related quality of life, and a temporary restricted functioning of the lower jaw. Nevertheless, bimaxillary osteotomy is considered a durable and effective treatment option for patients with obstructive sleep apnoea.
