目的观察三维CT引导下半月神经节射频热凝术治疗三叉神经痛临床疗效。方法 :方法在三维CT引导下应用改良的Hartel法经前入路卵圆孔穿刺半月神经节,术中电刺激试验验证靶点,在局麻或全身麻醉下进行靶点射频温控毁损。结果本组56例患者术后疼痛完全消失54例,2例患者疼痛减轻,仅需口服常规剂量药物即能控制疼痛,治愈率96.43%;54例术后出现面部麻木、2例术后患区窜跳痛、12例咀嚼力减弱、6例头痛眩晕,未发生严重并发症。结论 CT引导下半月神经节射频热凝术治疗原发性三叉神经痛安全可靠,效果显著,可减少穿刺过程因深度或方向掌握不当产生的并发症。
Objective To observe the clinical efficacy of radiofrequency thermocoagulation in the treatment of trigeminal neuralgia under the guidance of three-dimensional CT. Methods: The modified Hartel method was used to puncture the semilunar ganglion through foramen ovale under the guidance of three-dimensional CT. The target was confirmed by electrical stimulation during surgery and the target RF temperature was controlled by local anesthesia or general anesthesia. Results The pain disappeared completely in 54 patients in this group of 56 patients. Pain relief was relieved in 2 patients. The pain was relieved only by oral administration of conventional dosage. The cure rate was 96.43%. Fifty-four patients had facial numbness and two postoperative patients Phlegm, 12 cases of chewing force weakened, 6 cases of headache dizziness, no serious complications. Conclusion CT-guided radiofrequency thermocoagulation in the second half of the ganglion is safe and reliable in the treatment of primary trigeminal neuralgia and can reduce the complications caused by improper depth or orientation during the puncture.
