Abstract：
UNASSIGNED: There is increasing focus on the development of high-quality simulation models for medical education. Cadaveric models, although considered more realistic, may be difficult to obtain and costly. The advent of three-dimensional (3D) printing has offered a low-cost, reliable, and reproducible alternative. This study sought to compare the utility of 3D-printed to cadaveric models for training in transcutaneous injection laryngoplasty (TIL).
UNASSIGNED: A simulation course with a cross-over design was employed. Video laryngoscopes were utilized for both the 3D and cadaveric models to assess the accuracy of injection into the vocal fold. Pre-procedure and post-procedure surveys were administered to evaluate understanding and comfort level on a Likert scale of 1-10. Each model was also rated on a 1-5 Likert scale for self-efficacy, fidelity, and educational value.
UNASSIGNED: Pre- and post-survey data were completed by 15 otolaryngology residents and medical students. Mean pre-seminar understanding and comfort level were 3.7 and 2.2, respectively, compared to 6.9 and 5.9 (p < .05) following use of the 3D model and 6.4 and 4.7 (p < .05) following use of the cadaver model. When comparing 3D and cadaveric models, no significant differences were observed regarding self-efficacy, fidelity, and educational value.
UNASSIGNED: There was a similar mean increase in understanding and comfort following use of the 3D and cadaveric models. 3D-printing can provide an excellent adjunct to, and eventually a potential replacement for hands-on cadaveric training in medical education, particularly for TIL.
UNASSIGNED: Level III.

摘要：
■人们越来越关注用于医学教育的高质量模拟模型的开发。尸体模型，虽然被认为更现实，可能很难获得，而且成本很高。三维（3D）打印的出现提供了低成本，可靠,和可重复的替代品。这项研究旨在比较3D打印与尸体模型在经皮注射喉成形术（TIL）训练中的实用性。
■采用了交叉设计的模拟课程。视频喉镜用于3D和尸体模型，以评估注入声带的准确性。进行了术前和术后调查，以1-10的Likert量表评估理解和舒适度。每个模型还在1-5李克特量表上对自我效能感进行了评估，保真度，和教育价值。
■调查前后的数据由15名耳鼻喉科住院医师和医学生完成。研讨会前的平均理解力和舒适度分别为3.7和2.2，与使用3D模型后的6.9和5.9（p<0.05）以及使用尸体模型后的6.4和4.7（p<0.05）相比。在比较3D和尸体模型时，在自我效能感方面没有观察到显著差异，保真度，和教育价值。
■使用3D和尸体模型后，理解和舒适度也有类似的平均增加。3D打印可以提供一个很好的辅助，最终可能替代医学教育中的动手尸体培训，特别是TIL。
■三级。
