摘　　要：目的探讨3D打印经鼻蝶神经内镜手术训练模型的构建及其在神经内镜手术训练中的应用价值。方法通过3D打印方式制作经鼻蝶神经内镜手术训练模型。对制作的模型进行评价,并借助该模型对8名没有神经内镜操作经验的神经外科医师进行神经内镜操作培训。结果 3D打印经鼻蝶神经内镜手术训练模型可利用的操作空间与实际的神经内镜下经鼻蝶手术相似。固定在模型上的鸡蛋具有蛋壳、壳膜、蛋清和蛋黄等多层次的结构,是良好的镜下操作练习对象。经过训练,学员均表示能从中获益;在末次重复练习时,学员磨除蛋壳的效率[(1.07±0.22)cm^2/min vs.(1.45±0.27)cm^2/min,P<0.001]以及壳膜破裂概率(8 vs.2,P=0.007)均较初次练习时有明显改善(P<0.001)。结论该模型有助于神经外科医生熟悉神经内镜下基本操作和提高手术技巧,而且可重复使用。可作为尸颅标本操作训练之前的基础操作训练模型。Objective The aim of our study was to establish an endoscopic endonasal transsphenoidal surgical training model, and to examine its application value. Methods The endoscopic endonasal transsphenoidal surgical training models were made. After assessments, the models was used for endoscopic operation training for 8 neurosurgeons with no experiences of endoscopic operation. Results The available operating space of this model is similar to the actual operating space in endoscopic endonasal transsphenoidal surgery. The egg fixed on the model has many layers of structure, such as eggshell, shell membrane, egg white and egg yolk, which constituted a good practice object. All students indicated that they could benefit from the training using this model. The skill in grinding the eggshell [（1.07 ±0.221） cm^2/min vs.（1.45±0.27） cm^2/min, P〈0.001] was significantly improved and the chance for shell membrane rupture（8 vs. 2, P=0.007） was significantly reduced in the last-time practice compared with the first-time practice（P〈0.001）.Conclusion The endoscopic endonasal transsphenoidal surgical training model is helpful for neurosurgeons to practice the basic operation of endoscopic surgery and to improve their surgical skills, and can be used repeatedly. It can be used in basic operation training before the training using cadaver cranium.
