Orthognathic Surgery and Obstructive Sleep Apnea

The term orthognathic stems from the Greek words “ortho” (straight) and “gnathos” (jaws). It encompasses a vast array of maxillary and mandibular osteotomies employed for the correction and alignment of deformities of the facial skeleton in order to achieve proper form, function and esthetics.  This is a service that is provided typically in conjunction with orthodontic therapy and aims to correct major dento-facial malocclusions.

Obstructive Sleep Apnea is a disease of the upper airways that contributes to the cessation or significant decrease in breathing during sleep, which can lead to increased fatigue, difficulty concentrating and in more severe cases, predisposing to cardiovascular disease or even stroke. Maxillomandibular advancement surgery (upper and lower surgical jaw repositioning) is the most successful treatment of severe and debilitating forms of this disease.

The division of Oral and Maxillofacial Surgery performs orthognathic surgery routinely to treat a variety of skeletal abnormalities stemming from irregular growth, disorders of the temporomandibular joint, malocclusions not amenable to orthodontic therapy alone, residual post-traumatic defects and obstructive sleep apnea.
