Abstract:
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.
