The anatomically complex and often spatially restricted conditions of anastomosis in the head and neck region cannot be adequately reproduced by training exercises on current ex vivo or small animal models. With the development of a Realistic Anatomical Condition Experience (RACE) model, complex spatial-anatomical surgical areas and the associated intraoperative complexities could be transferred into a realistic training situation in head and neck surgery. The RACE model is based on a stereolithography file generated by intraoperative use of a three-dimensional surface scanner after neck dissection and before microvascular anastomosis. Modelling of the acquired STL file using three-dimensional processing software led to the model's final design. As a result, we have successfully created an economical, sustainable and realistic model for microsurgical education and provide a step-by-step workflow that can be used in surgical and general medical education to replicate and establish comparable models. We provide an open source stereolithography file of the head-and-neck RACE model for printing for educational purposes. Once implemented in other fields of surgery and general medicine, RACE models could mark a shift in medical education as a whole, away from traditional teaching principles and towards the use of realistic and individualised simulators.
在头颈部，吻合的解剖结构复杂，空间受限，目前的离体或小动物模型无法充分复制吻合训练。通过开发真实解剖条件体验（RACE）模型，可以将复杂的空间解剖手术区域和相关的手术复杂性转移到头颈部手术的真实培训环境中。RACE 模型基于颈清扫术和微血管吻合术之前术中使用三维表面扫描仪生成的立体光刻文件。使用三维处理软件对获取的 STL 文件进行建模，最终设计出模型。因此，我们成功地为显微外科教育创建了一个经济、可持续和真实的模型，并提供了一个可用于外科和一般医学教育的分步工作流程，以复制和建立可比模型。我们提供了头颈部 RACE 模型的开源立体光刻文件，以供打印用于教育目的。一旦在其他外科和一般医学领域实施，RACE 模型可能会标志着整个医学教育的转变，从传统的教学原则转向使用真实和个性化的模拟器。
