Craniosynostosis is a rare and complex pathology, and visuospatial skills are necessary for a good understanding of the condition. While the use of three-dimensional (3D) models has improved the understanding of complex craniofacial anatomy, no study has evaluated the impact of this teaching support on long-term retention. Our randomized controlled trial was designed to compare the long-term retention of information with 3D-printed models of four types of craniosynostosis versus classic 3D reconstructions displayed in two-dimensional (2D) among undergraduate students. All students benefited from the same standardized course followed by the manipulation of the learning tool associated with the group for 15 min. Long-term retention was assessed by the capability to properly recognize different types of craniosynostosis 3 weeks after the course. Eighty-five students were enrolled. Previous educational achievements and baseline visuospatial skills were similar between the groups. The bivariate analysis showed the mean score in the 3D and 2D groups were 11.32 (2.89) and 8.08 (2.81), respectively (p < 0.0001). 3D-printed models of structures with spatial complexity such as various craniosynostosis patterns improve significantly medical students' long-term retention, indicating their educational efficacy.
颅缝早闭是一种罕见且复杂的疾病，良好的空间感知能力对于理解这种疾病至关重要。虽然使用三维（3D）模型已经提高了对复杂颅面解剖结构的理解，但尚未有研究评估这种教学支持对长期记忆的影响。我们的随机对照试验旨在比较 3D 打印的四种颅缝早闭模型与二维（2D）显示的经典 3D 重建对本科生信息长期保留的影响。所有学生都受益于相同的标准化课程，然后在 15 分钟内使用与组相关的学习工具进行操作。课程结束 3 周后，通过正确识别不同类型颅缝早闭的能力来评估长期保留情况。共纳入 85 名学生。两组学生的先前教育成就和基线空间感知能力相似。双变量分析显示 3D 组和 2D 组的平均得分为 11.32（2.89）和 8.08（2.81），差异有统计学意义（p<0.0001）。具有空间复杂性的结构的 3D 打印模型，如各种颅缝早闭模式，显著提高了医学生的长期保留率，表明其具有教育效果。
