Plastic skull models of seven individual patients were fabricated by stereolithography from three-dimensional data based on computed tomography bone images. Skull models were utilized for neurosurgical planning and simulation in the seven patients with cranial base lesions that were difficult to remove. Surgical approaches and areas of craniotomy were evaluated using the fabricated skull models. In preoperative simulations, hand-made models of the tumors, major vessels and nerves were placed in the skull models. Step-by-step simulation of surgical procedures was performed using actual surgical tools. The advantages of using skull models to plan and simulate cranial base surgery include a better understanding of anatomic relationships, preoperative evaluation of the proposed procedure, increased understanding by the patient and family, and improved educational experiences for residents and other medical staff. The disadvantages of using skull models include the time and cost of making the models. The skull models provide a more realistic tool that is easier to handle than computer-graphic images. Surgical simulation using models facilitates difficult cranial base surgery and may help reduce surgical complications.
通过立体光刻技术，基于计算机断层扫描骨图像的三维数据，为七名个体患者制作了塑料颅骨模型。这些颅骨模型被用于七名颅底病变难以切除患者的神经外科手术规划和模拟。使用制作好的颅骨模型评估手术入路和开颅区域。在术前模拟中，将肿瘤、主要血管和神经的手工模型放置在颅骨模型中。使用实际手术工具对手术过程进行逐步模拟。使用颅骨模型进行颅底手术规划和模拟的优点包括更好地理解解剖关系、对拟议手术进行术前评估、患者及其家属理解的增加以及住院医师和其他医务人员教育体验的改善。使用颅骨模型的缺点包括制作模型的时间和成本。颅骨模型提供了一种比计算机图形图像更逼真且更易于操作的工具。使用模型进行手术模拟有助于复杂的颅底手术，并可能有助于减少手术并发症。
