OBJECTIVE/HYPOTHESIS: To assess the use of a three-dimensional (3D) printed, multilayer facial flap model for use in trainee education as an alternative method of teaching surgical techniques of facial reconstruction.
Cohort study.
A 3D printed facial flap simulator was designed from a computed tomography scan and manufactured out of silicone for low-cost, high-fidelity simulation. This simulator was tested by a group of Otolaryngology-Head and Neck Surgery trainees at a single institution. The simulator group was compared to a control group who completed an exercise on a traditional paper facial flap exercise. Both groups underwent didactic lectures prior to completing their respective exercises. Pre- and post-exercise Likert scale surveys measuring experience, understanding, effectiveness, and realism were completed by both groups. Central tendency, variability, and confidence intervals were measured to evaluate the outcomes.
Trainees completing the facial flap simulator reported a statistically significant (p < 0.05) improvement in overall expertise in facial flap procedures, design of facial flaps, and excision of standing cutaneous deformities. No statistically significant improvement was seen in the control group.
Trainees found the facial flap simulator to be an effective and useful training tool with a high level of realism in surgical education of facial reconstruction. Surgical simulators can serve as an adjunct to trainee education, especially during extraordinary times such as the novel coronavirus disease 2019 pandemic, which significantly impacted surgical training.

目的/假设：评估使用三维（3D）打印多层面部皮瓣模型作为教授面部重建手术技术的替代方法在学员教育中的应用。
队列研究。
从计算机断层扫描设计了 3D 打印的面部皮瓣模拟器，并由硅酮制成，以实现低成本、高保真度的模拟。该模拟器由一组耳鼻喉科-头颈外科学员在一家机构进行了测试。模拟器组与对照组进行了比较，对照组在传统的纸质面部皮瓣练习上完成了一项练习。两组在完成各自的练习之前都接受了理论讲座。两组都完成了术前和术后的李克特量表调查，以衡量经验、理解、效果和现实感。使用集中趋势、变异性和置信区间来评估结果。
完成面部皮瓣模拟器的学员报告说，在面部皮瓣手术的整体专业水平、面部皮瓣设计和切除站立性皮肤畸形方面有显著的（p < 0.05）提高。对照组没有观察到统计学上的显著改善。
学员认为面部皮瓣模拟器是一种有效的、有用的培训工具，在面部重建的手术教育中具有很高的现实感。手术模拟器可以作为学员教育的辅助手段，特别是在像 2019 年新型冠状病毒病这样的特殊时期，这对手术培训产生了重大影响。
