三维CT及X线卵圆孔定位射频热凝治疗顽固性三叉神经痛

目的：探讨三维CT及X线卵圆孔定位在三叉神经痛射频热凝治疗中的应用及手术技巧。方法：Hartel前入路穿刺法，仰卧位，对38例三叉神经痛病人，于射频热凝治疗术中应用三维CT及X线卵圆孔定位，以明确卵圆孔的位置，调整穿刺针的方向和深度，然后进行温控热凝射频治疗。结果：穿刺针均位于卵圆孔内，病人疼痛即刻缓解，无严重并发症发生。结论：三维CT及X线卵圆孔定位弥补了徒手穿刺的缺陷，提高了卵圆孔穿刺的成功率和精确性，增加了操作的安全性，降低了并发症的发生，具有一定的学术价值，可供临床推广应用。

A study of 3D-CT and X-ray oval foramen locations in the radiofrequency therapy of intractable trigeminal neuralgia

Objective: 3D-CT and X-ray oval foramen locations were performed in the radiofrequency therapy of intractable trigeminal neuralgia. Methods: Hartel's technique, dorsal position, 3D-CT and X-ray oval foramen locations were performed in 38 patients so that the direction and position could be defined for trigeminal neuralgia. Results: The needles located in oval foramen. Pain alleviated immediately but no serious complication occurred in all of the patients. Conclusion: X-ray and 3D-CT oval foramen locations can raise the successful rate of puncture, enhance the safety and reduce the incidence rate of complcation, which has high academic value and can be popularized in the future.
