Planning
Planning for the surgery usually involves input from a multidisciplinary team. Involved professionals are oral and maxillofacial surgeons, plastic surgeons, ENT surgeons, orthodontists, and speech and language therapist. As the surgery usually results in a noticeable change in the patient's face a psychological assessment is occasionally required to assess patient's need for surgery and its predicted effect on the patient.
Radiographs and photographs are taken to help in the planning and there is software to predict the shape of the patient's face after surgery, which is useful both for planning and for explaining the surgery to the patient and the patient's family. Advanced software can allow the patient to see the predicted results of the surgery.
The main goals of orthognathic surgery are to achieve a correct bite, an aesthetic face and an enlarged airway. While correcting the bite is important, if the face is not considered the resulting bony changes might lead to an unaesthetic result. Orthognathic surgery is also available as a very successful treatment (90-100%) for obstructive sleep apnea. Great care needs to be taken during the planning phase to maximize airway patency.

Famous quotes containing the word planning:
“For the people in government, rather than the people who pester it, Washington is an early-rising, hard-working city. It is a popular delusion that the government wastes vast amounts of money through inefficiency and sloth. Enormous effort and elaborate planning are required to waste this much money.”
—P.J. (Patrick Jake)
