Before Surgery
Orthognathic surgery is an option for patient
who has major facial discrepancies in terms of both dental
and skeletal relationships. It is a relatively common problem.
The surgery will help both aesthetically as well as improvement
in functionality such as occlusion, mastication and speech.
The pictures and illustrations below describe a case report
of surgery involving both the maxilla as well as the mandible.
A twenty-year-old man was referred by
his dentist to the Oral and Maxillofacial Department University
of Malaya, Kuala Lumpur, Malaysia. He dislikes his large jaw
and wants something done to it. It was decided that some decompensating
orthodontic treatment would be done and after that, a bimaxillary
osteotomy is planned and carried out.
Picture above shows occlusion before surgery
After Surgery
After eleven months of orthodontics, the patient
underwent a bimaxillary surgical procedure in which the lower
jaw was pushed back by 6mm via a sagittal split osteotomy
and the maxilla was pushed forward by 3 mm via a Le fort I
osteotomy. The picture below shows the patient six months
after the operation. Note that the profile has much improved
and the occlusion was restored to a Class I skeletal as well
as dental relationships. |
