背景：近年来，国内外对颅底卵圆孔穿刺定位问题研究较多，但多数定位方法对术者的个人经验要求较高，缺乏个体化的量化参数。 　　目的：建立颅底卵圆孔三维可视化数字模型，探索经皮穿刺颅底卵圆孔治疗三叉神经痛的合理手术穿刺路径及穿刺深度，探索个体化治疗三叉神经痛的方法。 　　方法：获取健康成年男性志愿者头颅的CT图像，导入三维重建软件MIMICS 10.01，生成颅骨及皮肤三维可视化模型，利用模型设计卵圆孔穿刺的路径，绘制颅底卵圆孔穿刺定位仪的初步模型。 　　结果与结论：采用CT扫描图像，通过MIMICS软件，建立了颅底卵圆孔穿刺路径的三维可视化数字模型。为临床教学提供了可靠的解剖资料，同时也为颅骨卵圆孔穿刺的手术模拟奠定了基础。在颅底卵圆孔穿刺路径三维模型基础上确定了“进针点”、“靶点”、“中点”等3个穿刺参照点，确定了由上述3点围成三角形所在平面为“定位平面”，以此为主要参数设计的定位仪，结构简单，操作方便、定位精度高，医患在射线下暴露时间短，在模拟层面，实现了颅底卵圆孔穿刺进针深度、进针方向的精确化、个体化。

BACKGROUND:In recent years, increasing research emphasizes the puncture position of the foramen ovale in skul , but most of the positin methods require a higher personal experience of surgeons and lack of individualized quantitative parameters. OBJECTIVE:To establish a visualized digital model of the foramen ovale in skul , explore the reasonable puncture path and puncture depth of percutaneous treatment of foramen ovale puncture for trigeminal neuralgia, and develop the individualized treatment of trigeminal neuralgia. METHODS:Head CT images from healthy adult male volunteers were obtained and were input into three-dimensional reconstruction software MIMICS 10.01, the three-dimensional visualized models of the skul and skin were established. Using the models, the puncture path of the foramen ovale was designed and the preliminary model of the puncture locator was plotted. RESULTS AND CONCLUSION:The three-dimensional visualized digital model of the foramen ovale puncture path was established with CT scan images by using MIMICS software, which provides reliable anatomical data for clinical teaching and lays the groundwork for the simulation of puncture surgery. On the three-dimensional models, the“needle points”,“target points”, and“midpoint”were determined, and the triangle consisted of the three points was regarded as“positioning plane”. Using these parameters, the positioning instrument is characterized by simple structure, convenient operation, high positioning precision and short period of exposure to radiation, it simulates the foramen ovale puncture needle depth and needle direction in a precise and individualized manner.
