A total of 1,337 patients underwent orthognathic surgery and evaluation for dentofacial deformity during the past 27 years from April 1991 to March 2018, in the Department of Oral and Maxillofacial Surgery, Fukuoka Dental College Medical and Dental Hospital. The results were as follows : 1.The average number of orthodontic surgery cases was 49.5 ± 14.4. 2.The patients were 351 males and 986 females, and the ratio of males to females was about 1 : 2.8. 3.Maxillary retrognathism+Mandibular prognathism was the most clinical diagnosis with 282 cases(21.2%), followed by mandibular prognathism with 217(16.2%), and facial asymmetry with 150(11.2%). 4.The average age of the patients was 25.1±1.5 years old(range : 14-65), and has been rising gradually. 5.Le Fort I osteotomy(L1)+Sagittal split ramus osteotomy(SSRO)was performed for most cases(702 cases. 52.5%). 6.The average operation time and amount of bleeding in L1+SSRO were 241.5±55.8 minutes and 552.1± 247.1ml, respectively. Those in SSRO were 157.5±35.0 minutes and 159.9 ± 84.2ml, respectively. 7.The duration of intermaxillary fixation is almost 5 days in recent years. 8.Hospitalization period was 27.3±2.6 days by the end of fiscal 2003. The time taken to provide a critical path, that has been 18.2±1.5 days for L1+SSRO cases and 16.4 ± 1.3 days for SSRO cases. 9.475 patients came from our orthodontic clinics and 655 were referred from other clinics.
在1991年4月至2018年3月的27年间，共有1337名患者在福冈牙科学院医学和牙科医院口腔颌面外科接受了正颌手术和牙面畸形评估。实验结果如下:1.实验结果表明:正畸手术例数平均为49.5±14.4例。2.男性351例，女性986例，男女比例约为1:1 .8。3.临床诊断最多的是上颌后颌+下颌前突282例(21.2%)，其次是下颌前突217例(16.2%)，面部不对称150例(11.2%)。4.患者平均年龄为25.1±1.5岁(14 ~ 65岁)，年龄呈逐渐上升趋势。5.多数病例(702例)行Le Fort I型截骨术(L1)+矢状分支截骨术(SSRO)。52.5%)。6.L1+SSRO的平均手术时间为241.5±55.8 min，出血量为552.1±247.1ml。SSRO组分别为157.5±35.0 min和159.9±84.2ml。7.近年来，上颌间固定时间约为5天。8.截至2003财政年度末，住院时间为27.3±2.6天。提供关键路径所需时间，L1+SSRO病例为18.2±1.5天，SSRO病例为16.4±1.3天。9475例患者来自本院正畸门诊，655例患者来自其他门诊。

Orthognathic surgery is thought to have a great impact on aesthetic appearance and psychology, and there are also cases where mental illness appears after surgery. Anorexia nervosa is a mental disorder characterized by per-sistent caloric intake restriction and a strong fear of weight gain and becoming obese; treatments include behavioral therapy. We report on the safe perioperative management without worsening of anorexia nervosa successfully treated by behavioral therapy with orthognathic surgery. The case was a 32-year-old female. A clinical diag-nosis of skeletal mandibular prognathism as a chief complaint was made; we aimed to improve her occlusal position, and so decided to perform surgical orthodontic treatment. There was a history of cleft palate, anorexia nervosa, binge-eating/purging, and attention-deficit/ hyperactivity disorder. All treatment in a behavioral therapy program for psychosomatic medicine of another hospital was interrupted, and the body weight dropped to 20kg one year before the jaw corrective surgery. Aiming to increase weight for surgery a few months before surgery, she was hospitalized in another department of psychosomatic medicine. When her weight increased to 35kg and meals of up to 1,600kcal/day could be eaten, it was judged that surgery was possible. Body weight at the time of hospitalization was 34.5kg, and on the day after hospitalization, bilateral sagittal split ramus osteot-omy was performed under general anesthesia, and postoperative sedation was attempted with dexmedetomidine until the day after surgery. In addition, the bone frag-ment was fixed to a metal plate, and after arousal, only intermaxillary rubber towing was performed. During hospitalization, no restrictions were imposed on drinking of water and favorite foods except during the fasting and prohibition of drinking water due to general anesthesia, and they were consumed mainly when the patient was able to ingest. Nutrition started with a high nutrient fluid diet from the day after surgery. This was changed to whole porridge and soft meal on the second postoperative day, and she was able to ingest the whole amount at discharge. The weight at the time of discharge was 36.7kg, and overeating or self-induced vomiting was not observed during hospitalization. It was thought that close cooperation with psychosomatic physicians before surgery, and perioperative management for behavioral therapy led to good results.

Introduction: For skeletal Class III malocclusions requiring surgical orthodontic treatment, labial inclination of the mandibular incisors is often necessary to improve dental compensation. However, the alveolar bone width of the mandibular symphysis in these patients is prone to be narrower than in patients with individual normal occlusion so that movement of the lower incisors is limited. Therefore, we investigated the alveolar bone width of the mandibular symphysis and molar areas in skeletal Class III malocclusion cases with either non-open bite or open bite without incisor attrition using cone-beam computed tomography (CBCT). Materials and Methods: Among patients 16 years old or older with skeletal Class III malocclusion who underwent CBCT, we enrolled 30 patients with open bite without incisor attrition and 30 patients with non-open bite. Using CBCT, we measured the width of the lingual side cortical bone at 2.0, 4.0, 6.0, and 8.0 mm below the cementoenamel junction (CEJ) and the width of the alveolar bone of the symphysis at 10 mm below the CEJ of the lower central incisor. Results : The mandibular anterior alveolar bone width, measured at 2.0, 4.0, 6.0, and 8.0 mm from the CEJ, was significantly narrower in the open-bite group than in the non-open-bite group. Between the distal root of the lower first molars and the second molars, the right buccal cortical bone of the open-bite group was significantly narrower at 6.0 mm and 8.0 mm from the CEJ than that of the non-open-bite group, but no significant difference was found in the left buccal cortical bone. Additionally, the right lingual cortical bone at 6.0 mm and the left lingual cortical bone at 2.0 mm and 4.0 mm from the CEJ were significantly narrower in the open-bite group than in the non-open-bite group. Furthermore, the width of the right alveolar bone was significantly narrower in the open-bite group than in the non-open-bite group at 8.0 mm from the CEJ. Discussion: In the case of patients with skeletal Class III malocclusion, there was less mechanical stimulation in the open-bite group than in the non-open-bite group. This suggests that the occlusal forces were smaller and the width of the mandibular molar alveolar and buccal cortical bone narrower in the open-bite group than in the non-open-bite group.
