Three-dimensional (3D) printed temporal bones are comparable to cadaveric temporal bones as a training tool for otologic surgery.
Cadaveric temporal bone dissection is an integral part of otology surgical training. Unfortunately, availability of cadaveric temporal bones is becoming much more limited and concern regarding chemical and biological risks persist. In this study, we examine the validity of 3D-printed temporal bone model as an alternative training tool for otologic surgery.
Seventeen otolaryngology trainees participated in the study. They were asked to complete a series of otologic procedures using 3D-printed temporal bones. A semi-structured questionnaire was used to evaluate their dissection experience on the 3D-printed temporal bones.
Participants found that the 3D-printed temporal bones were anatomically realistic compared to cadaveric temporal bones. They found that the 3D-printed temporal bones were useful as a surgical training tool in general and also for specific otologic procedures. Overall, participants were enthusiastic about incorporation of 3D-printed temporal bones in temporal bone dissection training courses and would recommend them to other trainees.
3D-printed temporal bone model is a viable alternative to human cadaveric temporal bones as a teaching tool for otologic surgery.
作为耳科手术的训练工具，三维（3D）打印颞骨与尸体颞骨相当。
尸体颞骨解剖是耳科手术训练不可或缺的一部分。不幸的是，尸体颞骨的可用性变得越来越有限，并且对化学和生物风险的担忧仍然存在。在本研究中，我们检验了3D打印颞骨模型作为耳科手术替代训练工具的有效性。
17名耳鼻喉科实习生参与了该研究。他们被要求使用3D打印颞骨完成一系列耳科手术。使用半结构化问卷评估他们在3D打印颞骨上的解剖经验。
参与者发现，与尸体颞骨相比，3D打印颞骨在解剖结构上逼真。他们发现3D打印颞骨总体上作为手术训练工具是有用的，对特定耳科手术也有用。总体而言，参与者对在颞骨解剖训练课程中纳入3D打印颞骨很感兴趣，并会向其他实习生推荐。
作为耳科手术的教学工具，3D打印颞骨模型是人体尸体颞骨的可行替代物。
