orthognathic surgery

reconstruction of the mandible, the maxilla, or both, performed to repair acquired or congenital facial defects like cleft palate. Surgery is usually not performed until the patient has enough permanent teeth to permit postoperative immobilization.

Root canal surgery is a common complication.
