In mandibular protrusion cases who undergo short lingual osteotomy(SL), interference between the distal mandibular segment and medial pterygoid muscle (MPM)is occasionally seen at setback operation. 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.

在下颌骨前突行短舌截骨术的病例中，下颌骨远端节段与内侧翼状肌(MPM)之间偶尔会出现干扰。这种干扰导致下颌中段后偏，影响术后稳定性。因此，使用术前CT图像三维检查MPM和中段之间的关系。本研究对18例下颌前突患者(男7例，女11例，平均初诊年龄22.4岁)进行了检查。所有病例均无先天性异常，Me侧偏在3mm以内。术前即刻(T1)、术后不到5周(T2)、术后1年以上(T3)均行侧位头颅造影。T1时进行ct检查。18例患者中有7例(U组)术后T2 ~ T3 Me前侧复发大于2.0mm, 11例(S组)术后复发小于2.0mm。利用CT DICOM数据对MTM进行三维重建，并分析其与下颌中段的关系。从T1到T2, S组和U组的下颌后退量和SNB角减小量无显著差异。U组出现下颌中段T1向T2的后偏，S组没有。MPM明显倾向于外侧U组低于组T1,表明病例组U展出近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)正畸分工,人类与发展和培养,Meikai大学牙科学院(负责人:须田直人教授)2)美开大学牙科学院诊疗科学部口腔颌面外科一科(主任:岛田俊教授)3)美开大学牙科学院诊疗科学部口腔放射学科(主任:木藤真司教授)270下颌支的邻近性。这些发现表明，在T1时，MPM与下颌分支的接近是造成干扰的危险因素之一，并影响手术后的稳定性。MTM和下颌骨的模拟可以预测SSRO术后的稳定性。

Facial asymmetry is known to have various causes, one of which is hemimandibular hyperplasia. 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.
