Treatment of obstructive sleep apnea with combined orthognathic-orthodontic approach assessed by nocturnal polysomnography.

This paper presents an evaluation of the effect of surgical mandibular advancement on obstructive sleep apnea (OSA) by sequential nocturnal polysomnography (NPSG). The case of a patient who had undergone several unsuccessful approaches is presented. The main outcome measures were assessed by the functional, occlusal, radiographic and esthetic changes achieved and also by reduction in the Apnea Hypopnea Index. After orthodontic preparation and advancement surgery, a normal over-jet and over-bite were established, the inferior pharyngeal airway space was increased, and there was a profound esthetic profile enhancement. His snoring and overall AHI significantly improved, and our patient is more rested and alert. The authors have concluded that mandibular and genioglossus advancement surgery illustrated objective improvement in the symptoms associated with severe OSA when measured by NPSG.
