Description
The patient was a 15-year 6-month female, and her chief complaint was severe nasomaxillary hypoplasia with anterior crossbite. After extraction of bilateral upper and lower third molars, the preoperative orthodontic treatment was initiated at 15-year and 7-month old. After 10-month orthodontic treatment, she received a surgery of intraoral LeFort II midfacial advancement using a piezoelectric braze. The naso-maxillary LeFort II segment was placed forward and downward by 8.0 mm using a Rigid External Distractor (RED) system, and internal rigid fixation was performed. For the mandible, the bilateral intraoral vertical ramus osteotomy was also performed, resulting in 6.0 mm mandibular setback. After 6-month of postoperative treatment, multi-bracket appliances were removed. At 7-month after surgery, the satisfactory facial profile and acceptable occlusion were obtained.
