An 18-year-old male with fibrous dysplasia of the right mandible was referred to our department for correction of facial asymmetry and scissors bite of the right molars. We planned posterior segmental osteotomy of the right maxilla and mandible after navigation-guided removal of the right bulging mandible. Mandibular navigation surgery was performed with an occlusal splint with titanium markers and reference frame, and facial symmetry was acquired postoperatively. Preoperative orthodontic treatment was performed, and posterior segmental osteotomy of the right mandible and maxilla combined with Le Fort I osteotomy was performed for correction of the scissors bite 1 year after navigation surgery for bone reduction. Postoperative orthodontic treatment has been performed for 9 months. Facial symmetry and ideal occlusion of the right molar area has been maintained for more than 3 years.
