对48例采用耳-床线定位射频治疗三叉神经痛的患者进行5年的回顾和分析,观察术后疼痛、复发及并发症情况。一次性穿刺成功率100%;经1次治疗疼痛完全消失者46例,疼痛明显减轻、发作次数明显减少者2例,无复发病例,无穿刺相关并发症发生。通过回顾分析确定穿刺针针尖到耳-床线垂直距离控制在:第Ⅲ支8～10mm,第Ⅱ支6～7mm,第Ⅰ支4～5mm。为避免三叉神经第Ⅰ支损伤,垂直距离控制在6mm以上而且针尖决不能超过耳-床线。
Forty-eight patients with trigeminal neuralgia treated with ear-bed line radiofrequency were retrospectively reviewed and analyzed for postoperative pain, recurrence and complications. One-time puncture success rate of 100%; after a treatment of pain disappeared in 46 cases, pain was significantly reduced, the number of seizures significantly reduced in 2 cases, no recurrence, no puncture-related complications. Through the retrospective analysis to determine the needle tip to the ear - the vertical distance of the bed line control: the first branch 8 ~ 10mm, the second branch 6 ~ 7mm, the first branch 4 ~ 5mm. In order to avoid the first branch of the trigeminal nerve injury, the vertical distance control in 6mm above and the needle tip can not exceed the ear - bed line.
