ORTHOGNATHIC SURGERY

Orthognathic surgery is surgery to correct conditions of the jaw and face related to structure, growth, sleep apnea, TMJ disorders, malocclusion problems owing to skeletal disharmonies, or other orthodontic problems that cannot be easily treated with braces. It is also used in treatment of congenital conditions like cleft palate. Bones can be cut and re-aligned, then held in place with either screws or plates and screws.

Orthognathic surgery is performed by either an oral and maxillofacial surgeon, plastic surgeon, or ENT in collaboration with an orthodontist. It often includes braces before and after surgery, and retainers after the final removal of braces. Orthognathic surgery is often needed after reconstruction of cleft palate or other major craniofacial anomalies. Careful coordination between the surgeon and orthodontist is essential to ensure that the teeth will fit correctly after the surgery.

The surgery might involve one jaw or the two jaws during the same procedure. The modification is done by making cuts in the bones of the mandible and / or maxilla and repositioning the cut pieces in the desired alignment. Usually surgery is performed under general anaesthetic and using nasal tube for intubation rather than the more commonly used oral tube; this is to allow wiring the teeth together during surgery. The surgery often does not involve cutting the skin, and instead, the surgeon is often able to go through the inside of the mouth.
