中文摘要

目的: 验证一种新型3D打印颞骨模型作为尸体人颞骨可接受替代品用于耳科手术训练的可行性。
方法: 由来自意大利各大学的54名耳外科医生(27名经验丰富者和27名受训者)对3D打印健康颞骨模型进行评估。参与者在模型上进行解剖操作,并完成一份27个问题的调查问卷,将合成模型与尸体模型进行比较。主要结局是平均总分超过3分的百分比,可接受性设定为>70%。
结果: 总体而言,80.9%(p < 0.001)的参与者认为该模型与尸体颞骨相当(平均总分超过3分)。在“作为训练工具的有用性”、“基于任务的有用性”和“总体反应”领域观察到高分,分别有95.8%(p < 0.001)、83.2%(p < 0.001)和79%(p = 0.004)的问卷平均总分超过3分。经验丰富的外科医生与受训外科医生之间的评估未发现显著差异。
结论: 3D打印颞骨模型是一种可行、成本效益高且可定制的训练工具,可与尸体相媲美。软组织的真实感仍需改进,以更好地模拟尸体标本。

英文摘要

OBJECTIVE: To validate a novel 3D-printed temporal bone model as an acceptable substitute for cadaveric human temporal bones in otosurgical training.
METHODS: A 3D-printed healthy temporal bone model was evaluated by 54 otosurgeons (27 experienced and 27 trainees) from Italian universities. Participants performed dissections on the model and completed a 27-question survey comparing the synthetic model with the cadaveric one. The primary outcome was the percentage of average total scores exceeding 3, with acceptability set at > 70%.
RESULTS: Overall, 80.9% (p < 0.001) of participants rated the model as comparable to the cadaveric temporal bone (average total score exceeding 3). High scores were observed for "usefulness as a training tool", "task-based usefulness" and "overall reactions" domains with an average total score exceeding 3 in 95.8% (p < 0.001), 83.2% (p < 0.001), and 79% (p = 0.004) of questionnaires respectively. No significant differences were found between experienced and trainee surgeons' evaluations.
CONCLUSIONS: 3D-printed temporal bone models are a viable, cost-effective, and customisable training tool comparable to cadavers. The realism of the soft tissues still needs to be refined in order to better mimic cadaveric specimens.
