RATIONALE
Traumatic brain injury is the most common cause of cranial defects. Cranioplasty is the surgical intervention performed to repair cranial defects. The purpose of a cranioplast is to protect the underlying brain tissues, reduce pain, and improve calvarial contour and symmetry.
PATIENT CONCERNS
This case report describes the management of an ambulatory aided patient who met with a road traffic accident and had undergone decompressive craniectomy.
DIAGNOSIS
Noncontrast computed tomography confirmed the frontal cranial defect and was planned for decompressive craniectomy.
TREATMENT PLAN
An innovative multi-camera three-dimensional (3D) face-scanning software (Bellus 3D) was used for facial scanning to obtain a 3D face model and fabrication of 3D model using rich presence technology.
OUTCOMES
The wax pattern was then fabricated on a 3D-prototyped model and a customised polymethylmethacrylate cranioplast was fabricated.
TAKE-AWAY LESSONS: his method with the added advantage of rapid prototyping technology resulted in prosthesis with good aesthetics and better fit.
原理
创伤性脑损伤是颅骨缺损最常见的原因。颅骨成形术是用于修复颅骨缺损的外科手术。颅骨成形术的目的是保护下方的脑组织、减轻疼痛，并改善颅骨轮廓和对称性。
患者情况
本病例报告描述了一名在交通事故中受伤并接受了减压颅骨切除术的门诊辅助患者的治疗情况。
诊断
非增强计算机断层扫描证实了额部颅骨缺损，并计划进行减压颅骨切除术。
治疗方案
使用一种创新的多摄像头三维（3D）面部扫描软件（Bellus 3D）进行面部扫描，以获得3D面部模型，并使用丰富呈现技术制作3D模型。
结果
然后在3D原型模型上制作蜡型，并制作定制的聚甲基丙烯酸甲酯颅骨修复体。
经验教训
这种方法加上快速成型技术的优势，使得修复体具有良好的美观性和更好的贴合度。
