This report describes a case of surgical orthodontic treatment for facial asymmetry caused by mandibular condylar fracture in infancy. A 14-year-old female was referred to our clinic for surgical orthodontic treatment with a chief complaint of facial asymmetry. She had experienced a right mandibular condylar fracture at 4 years of age, and had undergone open reduction and internal fixation. Subsequently, the growth of the mandible was disturbed, resulting in mandibular deviation and horizontal inclination of the occlusal plane. After preoperative orthodontic treatment, facial asymmetry and malocclusion were corrected by bimaxillary orthognathic surgery at age 16. The facial morphology and occlusion at 24 months postoperatively were satisfactory.
