Orthognathic Surgery
What is Orthognathic Surgery?
Orthognathic surgery falls under the umbrella of Oral and Maxillofacial Surgery. It is a form of surgery undertaken to assist in the treatment of a variety of conditions that stem from an incorrect positioning of the jaw.
The surgery involves the separation of the tooth bearing segments of the jaws from their underlying bony supports, and the selective repositioning and fixation of these segments, usually with plates and screws hidden under the soft tissues.
Orthognathic surgery is usually performed in conjunction with a carefully devised orthodontic treatment plan or may be undertaken in order to alleviate the condition of sleep apnoea in a patient.
Indications for orthognathic surgery
The majority of people who undergo orthognathic surgery do so as part of a combined orthodontic and surgical team approach. These people often have an underlying jaw misalignment which orthodontics alone cannot treat. This may include people with large upper or lower jaws relative to the other jaw, people with large or deficient chins, and people who have a significant facial asymmetry.
Another major indication for orthognathic surgery is the surgical management of obstructive sleep apnoea. These patients will almost always be managed in conjunction with their sleep physician.
