Oral and maxillofacial surgery (OMS) refers to surgery performed on the craniomaxillofacial complex, consisting of the skull, mouth, jaws, neck, face, and surrounding tissues, such as nerves and muscles. Severe facial trauma, tumors, congenital defects in the facial region, and aesthetics are the most important reasons for undergoing OMS. OMS deals primarily with the reconstruction, cutting, and relocation of bones in the facial area, also called orthognathic surgery, and treatment of soft tissues of the face in plastic and reconstructive surgery.
