3D打印颅骨在颅底解剖教学中的应用

Application of three-dimensional printed skull in the teaching of human anatomy

目的旨在探究3D打印技术制作解剖教具应用于医学解剖教育的可行性。方法用CT扫描获取大体颅骨标本影像数据,重建并采用3D打印技术构建颅骨模型。招募26名北京协和医学院三年级医学生,采用3D打印颅骨模型进行颅底解剖学习,并通过主观评价问卷对其在解剖教学中的实用性进行评价。结果 57%试验参与者认为3D打印颅骨能够完整呈现颅底解剖结构,超过90%参与者同意3D打印模型有助于空间理解和解剖学习,88%参与者认为3D打印颅骨能够解决大体解剖标本带来的伦理学问题,84%参与者赞同将3D打印模型应用于颅底解剖教学。结论 3D打印模型在解剖教学中效果得到了肯定,3D打印技术在医学教育中的进一步应用亟待展开。

Objective This experiment aimed to find out the feasibility of applying 3D printing technology to anatomy education. Methods We constructed 3D printed skull using a cadaveric skull as template. 26 participants were recruited from Peking Union Medical College. All participants studied cranial anatomy with 3D printed skulls asteaching materials,and then assessed practicability of 3D printed skulls by subjective assessment questionnaires.Results 57% participants considered that 3D printed skulls can present defined cranial anatomical structures. More than 90% participants agreed that 3D printed models helped spatial comprehension and study of anatomy. 88% participants suggested 3D printing can solve the problem of ethics. 84% participants agreed to apply 3D printed models into cranial anatomy education. Conclusions The efficacy of 3D printing had been confirmed in anatomical education. Further application of 3D printing technology in medical education needs carrying out.
