Orthognathic surgery is performed to alter the shape of the jaws to improve dental
occlusion stability, improve temporomandibular joint function, open the oropharyngeal
airway, and improve the patient’s facial proportions. Surgery must be coordinated
with orthodontic treatment. The surgeon develops a plan based on the patient’s
measurements and performs the planned procedure on plaster models of the patient’s
jaw and teeth to obtain the proper jaw position. Surgical techniques include LeFort
procedures and distraction osteogenesis. Possible complications of orthognathic
procedures include airway compromise, numbness, and nonunion or malunion of the
bones. Postoperative instructions include an emphasis on the need for the patient to
consume a blended diet for six weeks after surgery. AORN J 92 (July 2010) 28-49.
