title: Radiography after orthognathic surgery. Part I. Normal appearance.
abstract: Osteotomies of the mandible and/or maxilla (orthognathic surgery) are common procedures for correcting facial defects. Radiographs of these patients are routinely obtained, and the radiologist must be aware of the normal postoperative appearance as well as surgical complications that may occur. This article presents the common surgical procedures done (sagittal split, vertical subcondylar, genioplasty mandibular osteotomies; and Le Fort I and mid-palatal split maxillary osteotomies) and the routine appearance of uncomplicated procedures on posteroanterior skull and panoramic radiographs. The metallic immobilization devices and orthodontic appliances are also described.
