抄録

A survey of the current status of the treatment of jaw deformity in Japan was carried out. Cards requesting participation in the survey were sent to the members of the Japanese Society for Jaw Deformities and 189 facilities (89 clinics of oral and maxillofacial surgery, three clinics of plastic surgery and 97 clinics of orthodontics) answered the questionnaire on the homepage of the Japanese Society for Jaw Deformities. The number of patients who received orthognathic surgeries for jaw deformities between April 2006 and March 2007 in 92 clinics of oral and maxillofacial surgery or plastic surgery was 2926. Regarding the clinical diagnosis, the number of patients with mandibular protrusion with/without open bite and/or asymmetry was 1977 accounting for 68% of all patients. Regarding surgical techniques, bilateral sagittal split osteotomy (BSSO; 2069 cases) was most frequent, accounting for 71%, followed by Le Fort I osteotomy in 787 cases (27%). Intraoral vertical ramus osteotomy, alveolar osteotomy, genioplasty, distraction osteogenesis and other surgical types were applied in 370 cases (13%), 191 cases (7%), 318 cases (11%), 77 cases (2.6%) and 77 cases (2.6%), respectively. Rigid or semi-rigid osteosynthesis systems were used in almost all facilities. The average duration of preoperative orthodontic treatment in non-extraction cases and extraction cases was 13 and 18 months, respectively, and the average duration of postoperative orthodontic treatment was 11 months. The average operation time was 163 minutes and the amount of bleeding was 203ml in BSSO, and those in two-jaw surgery were 285 minutes and 512 ml, respectively. There was a significant correlation between operation time and blood loss in BSSO and two-jaw surgery. The average durations of hospital stay in mandibular osteotomy cases and in two-jaw surgery cases was 15 and 17 days, respectively. Intermaxillary fixations in cases using a metal osteosynthesis system and those using a bioresorbable osteosynthesis system were done in 67 and 29 clinics, respectively, and the respective average duration of intermaxillary fixations was 10 and 11 days. This study revealed the current status of treatment of jaw deformity in Japan.
