The most common surgical procedures are Le FortⅠosteotomy and sagittal split ramus osteotomy(SSRO). Gen-erally, their postoperative course is uneventful. In many facilities in Japan, the plates are removed approximately one to two years after osteotomy. We report a case of refixed non-unioned maxilla caused by a fractured plate, 15 months after a Le FortⅠosteotomy, which has not been reported previously. A 43-year-old man visited our hospital with a chief complaint of concave profile and malocclusion. Subse-quently he underwent Le FortⅠosteotomy and SSRO. Facial findings were symmetric from the frontal view and a concave profile from the lateral view. Intraoral findings revealed an overjet of −8 mm and an overbite of +5 mm, showing Class Ⅲ molarization. Cephalometric analysis revealed ANB: −13.4°, U1 to SN: 108.1°, L1 to mandible: 69.0°, FMA: 19.0° and gonial angle: 121.3°. He was diagnosed as Skeletal Ⅲ and Dental Class Ⅲ with a low mandible and short face. Intraoperatively, the maxillary segments were rigidly fixed by 5 titanium plates in the piriformis margin and zygomatic buttress after the maxilla advanced 5 mm. They were not filled with an autogenous bone graft after the Le FortⅠosteotomy because we confirmed immobilization of the maxilla. The patient was satisfied with the results of the opera-tion. The postoperative course has been uneventful since then. However, mobility of the maxilla was found 15 months after the Le FortⅠosteotomy. We diagnosed this as a non-unioned maxilla, and performed surgery to refix the non-unioned maxilla. One of the titanium plates in the piriformis margin on the right side had completely fractured, and the other titanium plates had become loose. Therefore, the fractured plate and another plate were replaced by new ones. In addition, a bone graft harvested from the mandibular ramus was placed with screws in the gap between the maxillary segments. At present, the postoperative course has been uneventful without complications to date. We need to take into ac-count the possibility of plate fractures for patients with short faces, due to the overload coming from the occlusal force and the necessity of a larger movement.","PeriodicalId":102257,"journal":{"name":"The Japanese Journal of Jaw Deformities","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114600632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This condition causes malocclusion as well as facial asymmetry. Here, we describe the combined surgery and orthodontic treatment performed for a patient with facial asymmetry accompanied by inclination of the maxillary occlusal plane as a result of mandibular asymmetry caused by hemimandibular hyperplasia. Based on the progress of bone scintigraphy, it was determined that accumulation in the mandible was ongoing and that condylectomy was required. Preoperative simulations conducted with the attending surgeon did not produce satisfactory occlusion with condylectomy alone, and it was therefore decided to simultaneously carry out maxillary and mandibular repositioning. Consequently, favorable occlusion was obtained during dynamic orthodontic treatment, and the facial features were improved. Furthermore, a satisfactory occlusal status was observed two years after the completion of dynamic orthodontic treatment.","PeriodicalId":102257,"journal":{"name":"The Japanese Journal of Jaw Deformities","volume":"44 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126807091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interference causes posterior deviation of the mesial mandibular segment and affects the postoperative stability. Thus, the relationship between the MPM and the mesial segment was examined three-dimensionally using preoperative CT images. In this study, 18 cases of mandibular protrusion(7 males and 11 females, average age at first visit : 22.4 years old)who visited Meikai University Hospital were examined. All cases were not affected by any congenital anomalies, and the lateral deviation of Me was within 3 mm. Lateral cephalograms were taken immediately before surgery(T1), less than 5 weeks after surgery (T2), and more than 1 year after surgery(T3). CTs were taken at T1. Seven of the 18 cases showed postoperative anterior relapse of more than 2.0mm at Me from T2 to T3(group U). The relapse of the other 11 cases(group S)was 2.0mm or less. Using DICOM data of CT, MTM was reconstructed three-dimensionally, and the relationship with the mesial mandibular segment was analyzed. There was no significant difference in the amount of mandibular setback and decrease in SNB angle between group S and group U from T1 to T2. Group U, but not group S, showed posterior deviation of the mesial mandibular segment from T1 to T2. MPM was significantly inclined less laterally in group U than group S at T1, indicating that cases in group U exhibited closer 1)明海大学歯学部形態機能成育学講座歯科矯正学分野(主任:須田直人教授) 2)明海大学歯学部病態診断治療学講座口腔顎顔面外科学分野 1(主任:嶋田 淳教授) 3)明海大学歯学部病態診断治療学講座歯科放射線学分野(主任:鬼頭慎司教授) 1)Division of Orthodontics, Department of Human and Development and Fostering, Meikai University School of Dentistry (Chief : Prof. Naoto SUDA) 2)First division of Oral and Maxillofacial Surgery, Department of Diagnostic and Therapeutic Sciences, Meikai University School of Dentistry(Chief : Prof. Jun SHIMADA) 3)Division of Dental Radiology, Department of Diagnostic and Therapeutic Sciences, Meikai University School of Dentistry (Chief : Prof. Shinji KITO) 270 日顎変形誌 2019 年 東金 由莉,他 proximity of MPM to the mandibular ramus.
