We present a case of Crouzon disease treated by two-jaw surgery after a Le Fort III osteotomy and bone distraction.The patient was a 17-year, 1-month-old male with facial malformation and malocclusion.At the age of 17 years and 2 months, a Le Fort III osteotomy and bone distraction were performed for midface advancement. After this distraction procedure, orthodontic treatment began for secondary surgery to correct severe openbite, bimaxillary protrusion, and spaced arch.After a partial glossectomy was carried out, preoperative orthodontic treatment commenced. At the age of 19 years and 7 months, a Le Fort I osteotomy and sagittal split ramus osteotomies (two-jaw surgery) were carried out.After postoperative orthodontic treatment, occlusion and the facial profile were improved. Although some spaces developed, the occlusal results were almost preserved throughout the 17 month retention period.
