目的探讨应用自制定位器结合CT扫描定位进行射频温控热凝术治疗三叉神经痛的准确性及有效性。方法 153例三叉神经痛患者应用自制定位器及CT扫描定位行射频温控热凝术,检查及随访手术效果。结果所有患者穿刺成功,穿刺针定位于卵圆孔半月神经节三叉神经病变分支,全部患者术后疼痛症状明显改变,并且没有严重并发症发生。结论应用自制定位器及CT扫描定位进行射频温控热凝术治疗三叉神经痛安全、准确、有效,值得临床推广。 Objective To investigate the accuracy and effectiveness of radiofrequency thermocoagulation for the treatment of trigeminal neuralgia with self-made positioner combined with CT scanning. Methods 153 cases of trigeminal neuralgia patients with self-made positioner and CT scan positioning radiofrequency thermocoagulation, inspection and follow-up results. Results All the patients were successfully punctured. The puncture needle was located in the branch of the foramen ovale semitendinous ganglion trigeminal nerve. The postoperative pain symptom of all the patients changed obviously, and no serious complication occurred. Conclusion It is safe, accurate and effective to treat trigeminal neuralgia by using self-made positioner and CT scan for radiofrequency thermocoagulation. It is worthy of clinical promotion.
