[Benef its of innovation in orthognathic surgery for OSA].

Obstructive sleep apnea (OSA) is a common, multifactorial disease resulting in high morbidity and mortality. Gold standard treatment is nocturnal positive airway pressure. Maxillomandibular advancement is a surgical technique used to treat obstructive sleep apnea. Development of guided surgery has modified patient care in cases of maxillomandibular dysgnathia. Two case reports illustrate the impact of new technologies on surgical treatment of this condition. New technologies such as the recent development of surgical guides help surgical management.
