The successful reduction of a nasomaxillary fracture was performed using a three-dimensional printed model. A 16-year-old boy was struck in the left orbit by a baseball; subsequently, he was diagnosed with the nasal bone fracture at a hospital, and was referred to the authors' department. A left nasomaxillary fracture and nasal bone fracture were diagnosed by computed tomography. Standard triangulated language data for the mirror image of the frontal process of the right maxilla were obtained from digital imaging and communications in medicine data for preparing a three-dimensional printed acrylonitrile butadiene styrene model. On postinjury day 13, the frontal process fracture was reduced via transconjunctival and intraoral approaches. After the reduction of the fracture, an absorbable plate fitting to the shape of three-dimensional printed acrylonitrile butadiene styrene model was molded, and the maxillary frontal process and infraorbital rim were reduced and fixed with an absorbable plate and screws. Postoperative computed tomography demonstrated a favorable reduction. The intraoperative use of the 3D printed acrylonitrile butadiene styrene model was helpful in the nasomaxillary fracture reduction and fixation.
使用三维打印模型成功复位了鼻上颌骨骨折。一名16岁男孩被棒球击中左眼眶；随后，他在一家医院被诊断为鼻骨骨折，并被转诊至作者所在科室。通过计算机断层扫描诊断为左鼻上颌骨骨折和鼻骨骨折。从医学数字成像和通信数据中获取右侧上颌骨额突镜像的标准三角测量语言数据，以制备三维打印丙烯腈丁二烯苯乙烯模型。受伤后第13天，通过经结膜和口内入路复位额突骨折。骨折复位后，根据三维打印丙烯腈丁二烯苯乙烯模型的形状制作一个可吸收板，用上颌额突和眶下缘用可吸收板和螺钉进行复位和固定。术后计算机断层扫描显示复位良好。术中使用3D打印丙烯腈丁二烯苯乙烯模型有助于鼻上颌骨骨折的复位和固定。
