Introducing a preoperative image simulation technique to streamline the visualization of the foramen ovale in percutaneous microcompression.
Twenty-five trigeminal neuralgia patients were included in the study. Preoperative cranial computed tomography scans were processed with 3D Slicer software to create simulated fluoroscopic skulls. The angulations required for precise visualization of the foramen ovale were established via simulated anteroposterior imaging. These simulations informed the C-arm's angulations for foramen ovale targeting during surgery.
The preoperative simulations accurately forecasted skull rotation angulations, aligning closely with intraoperative observations with negligible discrepancies (0-2 degrees). In 17 patients, the foramen ovale was distinctly visible, while in 8 patients, it was partially obscured yet discernible using the simulated angles. Nonvisible of the foramen ovale did not occur. Postoperative pain relief and complications were recorded.
Based on our initial findings, the application of preoperative image simulation shows significant referential value in achieving accurate visualization of the foramen ovale in percutaneous microcompression for trigeminal neuralgia.
引入术前图像模拟技术，以简化经皮微压缩中卵圆孔的可视化。
研究纳入 25 例三叉神经痛患者。对术前颅部 CT 扫描进行 3D Slicer 软件处理，以创建模拟透视颅骨。通过模拟前后成像确定准确可视化卵圆孔所需的角度。这些模拟为手术中卵圆孔靶向的 C 臂角度提供了信息。
术前模拟准确预测了颅骨旋转角度，与术中观察结果非常吻合，差异极小（0-2 度）。在 17 例患者中，卵圆孔清晰可见，而在 8 例患者中，使用模拟角度可以部分显示但仍可识别。未出现卵圆孔不可见的情况。记录术后疼痛缓解和并发症。
根据我们的初步发现，术前图像模拟的应用在经皮微压缩治疗三叉神经痛中实现卵圆孔的准确可视化方面具有重要的参考价值。
