[Mandibular anterior alveolar osteotomy and patient with malocculusion and facial deformity after healed mandibular fracture; report of a case].

Recent advances in orthognatic surgery have been remarkable. Among the surgical procedures, sagital ramus osteotomy has been often used for mandibular protrusion. Causes of dentofacial deformities include not only congenital but also acquired ones, which are caused by trauma or resection of tumor in the maxillofacial region. In all cases, functional and psychological disorders would often occur in the patient with these dentofacial deformities. We report a favorable result of anterior alveolar osteotomy of the mandible, which was applied to a patient complaining of malocculusion and facial deformity developed from a healed fracture of the mandible treated at another hospital.
