ORTHOGNATHIC (JAW) SURGERY
Orthognathic surgery refers to “straightening of the jaw(s) using surgery” [ortho – straight, gnathic – jaw(s)]. Whereas orthodontic treatment corrects the position of the teeth, orthognathic surgery positions the bones of the jaws (maxilla/mandible). One or both jaws may be surgically repositioned during one operation. This involves making cuts (osteotomies) in the bones and moving the cut segments into their predetermined position under a general anaesthetic. The surgery is normally preceded by a period of orthodontic treatment so that postoperatively both the teeth and the bones will be in their correct position. Finally, a short period of orthodontic treatment is then usually required to complete the alignment of the teeth.

Who performs orthognathic surgery?
Corrective Jaw Surgery. Corrective jaw surgery – also called orthognathic surgery – is performed by an oral and maxillofacial surgeon (OMS) to correct a wide range of minor and major skeletal and dental irregularities, including the misalignment of jaws and teeth. Surgery can improve chewing, speaking and breathing.
How dangerous is jaw surgery?
With orthognathic surgery, the major risks include bleeding; poor blood supply to the osteotomized jaw segments; infection; unfavourable bone cuts/splits; permanent numbness/tingling to lips, cheeks, and/or teeth; incorrect positioning of the jaws/segments; jaw joint problems; and damage to teeth.
Is orthognathic surgery painful?
During the surgery, you shouldn’t feel anything. After the surgery, some patients say it’s about as bad as getting your wisdom teeth taken out, except the swelling is a bit more. You likely will be sore and take prescription pain medication
