Deconstructing surgeries into steps and providing instructions with illustrations has been the staple of surgical textbooks for decades. However, it may be difficult for the novice surgeon to interpret 2-dimensional (2D) illustrations into 3D surgeries. The objective of this study is to create operable models that demonstrate the progression of surgery in 3D and allow for mastering the final steps of the operation first. Mastoidectomy was performed in a stepwise fashion to different end points on 5 identical 3D-printed temporal bone models to represent 5 major steps of the operation. The drilled models were computed tomography scanned and the subsequent images were used to create 3D model copies of each step. This is the first study to demonstrate that it is possible to create, scan, and copy stepwise, operable, patient-specific 3D-printed models, which the trainee can both reference as a 3D dissection guide and can operate on repeatedly and in any order.
几十年来，将手术分解为各个步骤并配以插图说明一直是外科教科书的主要内容。然而，对于新手外科医生来说，可能难以将二维（2D）插图转化为三维手术过程。本研究的目的是创建可操作模型，以三维方式展示手术进程，并允许先掌握手术的最后步骤。在5个相同的3D打印颞骨模型上逐步进行乳突切除术，直至不同的终点，以代表手术的5个主要步骤。对钻孔后的模型进行计算机断层扫描，并利用后续图像创建每个步骤的3D模型副本。这是第一项证明可以创建、扫描并复制逐步的、可操作的、针对患者的3D打印模型的研究，实习医生既可以将其作为三维解剖指南参考，又可以按任何顺序反复操作。
