다국어 초록 (Multilingual Abstract)

We have met a 21-year-old man with mandibular prognathism and excessive long face. At first, he had been admitted to department of orthopedic surgery for muscle weakness of the left forearm. He received open muscle biopsy under general anesthesia and other intensive study was also done but definitive diagnosis was deferred only to resu1t in R/0 Marfan`s syndrome. Thereafter, he was admitted to our department because of facial esthetic problem in the course of orthodontic treatment, We have obtained good results by surgical approach as follows; 1. Orthognatic surgery could be performed more easily on the patient with orthodontic treatment than not. 2. Intermaxillary fixation after surgery was done sufficently by using previously attached direct bonding system instead of removing them, 3. Improvement of anterior facial height was augmented via reduction genioplasty combined by orthodontic treatment. 4. The prognosis was good becuse of markedly reduced relapse which is one of the most common complications in orthognatic surgery, probably due to stable occlusion and fixation. 5. The preoperative and postoperative orthodontic treatment is essential to achievement of harmonized occlusion in complicated orthognatic surgery.
