The aim of this study was to determine the efficacy of using 3D printing models in the learning process of orbital anatomy and pathology by ophthalmology residents.
A quasi-experimental study was performed with 24 residents of ophthalmology at Mashhad University of Medical Sciences. Each stratum was randomized into two groups. The educational booklets were distributed, and various forms of orbital 3D models were printed from orbital computed tomography (CT) scans. Knowledge enhancement on the topics was measured by comparing pretest and posttest scores.
Thirteen residents who were trained using traditional methods were deemed the control group; while 11 residents who were trained using the 3D printed models were classed as the intervention group. The control group was younger than the intervention group ( = 0.047). The results showed that there was a statistically significant difference in the total posttest scores between the two groups. Based on the repeated measures of the analysis of variance (ANOVA), score variables were significant between the two groups ( = 0.008). Interestingly, the use of the 3D educational model was more effective and statistically significant with the year one residents as compared to the year two residents ( = 0.002).
This study is the first one in Iran quantifying the effects of learning using 3D printed models in medical education. In fact, 3D modeling training is seemingly effective in teaching ophthalmic residents. As residents have never encountered such technology before, their experience using 3D models proved to be satisfactory and had a surprising positive effect on the learning process through visual training.
本研究旨在确定3D打印模型在眼科住院医师眼眶解剖学和病理学学习过程中的有效性。
对马什哈德医科大学的24名眼科住院医师进行了一项准实验研究。每个层次随机分为两组。分发了教育手册，并从眼眶计算机断层扫描（CT）中打印出各种形式的眼眶3D模型。通过比较测试前和测试后的分数来衡量对这些主题的知识增强情况。
13名使用传统方法培训的住院医师被视为对照组；而11名使用3D打印模型培训的住院医师被归类为干预组。对照组比干预组年轻（P = 0.047）。结果表明，两组之间的测试后总分存在统计学上的显著差异。基于方差分析（ANOVA）的重复测量，两组之间的分数变量具有显著性（P = 0.008）。有趣的是，与二年级住院医师相比，3D教育模型对一年级住院医师的使用更有效且具有统计学显著性（P = 0.002）。
本研究是伊朗第一项量化3D打印模型在医学教育中学习效果的研究。事实上，3D建模培训在教导眼科住院医师方面似乎是有效的。由于住院医师以前从未接触过此类技术，他们使用3D模型的体验被证明是令人满意的，并且通过视觉训练对学习过程产生了惊人的积极影响。
