To investigate the value of 3-dimensional (3D)-printed models with pathologic entities in enhancing the learning curve of surgery of tuberculum sellae meningioma.
We printed 4 models of tuberculum sellae meningiomas based on radiologic data using a 3D printer. Participants were allocated to the 3D group and the atlas group. In the 3D group, participants learned surgery with the assistance of 3D models. In the atlas group, participants used only 2-dimensional materials to assist their learning. All participants undertook a pre-test and post-test. The scores were used to identify the difference in learning efficiency between the 2 groups.
A total of 42 new trainees were recruited, of whom 22 were in the 3D group and 20 in the atlas group. The baseline data were not significantly different. The difference of pre-test score was not significant, either. However, the post-test score was significantly greater in the 3D group (P = 0.005), and the change in score was also significantly greater in the 3D group (P < 0.001). In accordance with the objective test, the subjective survey through a questionnaire from participants in the 3D group showed that 3D models significantly promoted the learning curve of this kind of complex skull base surgery.
3D-printed models can assist in improving the learning curve of surgery of tuberculum sellae meningiomas. It particularly aids in memorization and spatial construction, improves understanding of surgical view, and arouses interest on the part of the trainee. We recommend using it in the education of complex skull base surgery.
探讨带有病理实体的三维（3D）打印模型在提高鞍结节脑膜瘤手术学习曲线方面的价值。
我们基于放射学数据使用3D打印机打印了4个鞍结节脑膜瘤模型。参与者被分为3D组和图谱组。在3D组中，参与者借助3D模型学习手术。在图谱组中，参与者仅使用二维材料辅助学习。所有参与者都进行了预测试和后测试。分数用于确定两组学习效率的差异。
共招募了42名新学员，其中3D组22名，图谱组20名。基线数据无显著差异。预测试分数的差异也不显著。然而，3D组的后测试分数显著更高（P = 0.005），3D组的分数变化也显著更大（P < 0.001）。根据客观测试，3D组参与者通过问卷调查进行的主观调查显示，3D模型显著促进了这种复杂颅底手术的学习曲线。
3D打印模型有助于改善鞍结节脑膜瘤手术的学习曲线。它特别有助于记忆和空间构建，提高对手术视野的理解，并激发学员的兴趣。我们建议在复杂颅底手术教育中使用它。
