目的 探讨三维CT引导下以经皮颧弓下紧贴下颌骨的乙状切迹上缘为皮肤穿刺点,经侧入路的卵圆孔穿刺方法,为选择性射频热凝半月神经节治疗三叉神经痛,提供一种新的可行性治疗途径.方法 取已锯开顶骨的成年人颅骨标本3具,用22G射频穿刺针分别模拟Hartel前入路及侧入路穿刺,针尖均进入卵圆孔内,应用CT对带有穿刺针的颅骨标本进行扫描,建立卵圆孔穿刺的CT下标准影像.依据CT重建的图像数据,对两种不同路径的穿刺针体、针尖位置关系进行测量、分析,获得侧入路穿刺到达半月神经节靶点的规律和技巧.同时选取2022年3月至2023年2月山东第一医科大学第一附属医院疼痛科收治行侧入路穿刺进入卵圆孔,对半月神经节进行温控射频热凝治疗的64例原发性2、3支三叉神经痛患者临床资料进行回顾性分析,观察疗效及感觉减退情况.结果 通过穿刺针和颅骨标本配合,经由CT扫描及重建图像,对比两种穿刺路径,指导CT引导下经皮侧入路卵圆孔穿刺技术的建立.对64例原发性三叉神经第2、3支疼痛患者应用该技术进行穿刺,均可成功进入卵圆孔,实现了对半月神经节选择性的射频热凝治疗.术后随访1周至12个月,平均(6.0±1.9)个月,患者疗效满意且无复发.结论 CT引导下经皮颧弓下紧贴下颌骨的乙状切迹上缘为皮肤穿刺点,侧入路卵圆孔穿刺技术,为选择性射频热凝半月神经节治疗三叉神经痛提供一种疗效确切、可行的、值得临床推广的治疗途径.
Establishment and application of three-dimensional computed tomography reconstruction-guided percutaneous lateral approach for foramen ovale puncture
Objective To investigate three-dimensional computed tomography(CT)-guided percutaneous lateral ap-proach for foramen ovale puncture and introduce a novel method for treating trigeminal neuralgia through selective radio-frequency thermocoagulation.Methods Three adult skull specimens with sawn parietal bones were scanned using a 22 G radiofrequency puncture needle.The Hartel anterior and lateral approaches for puncture were simulated.The needle tips were inserted into the foramen ovale,followed by skull CT scan with the puncture needles in place.The specimens were scanned to establish a standard image for CT perforations.Using the CT reconstruction data,the relationship be-tween the needle positions and tips for the two pathways was measured and analyzed.This analysis helped determine the techniques and skills required for the lateral approach puncture to accurately target the semilunar ganglion.Additionally,the clinical data of 64 patients with primary trigeminal neuralgia types 2 and 3,who were treated with radiofrequency thermocoagulation in the Gasserian ganglion from March 2022 to February 2023,were retrospectively analyzed to assess treatment efficacy and sensory loss.Results Using the needle and skull specimen,complemented by CT scan and im-age reconstruction,two puncture pathways were compared.The CT-guided percutaneous lateral approach facilitated the successful establishment of a foramen ovale perforation,which was applied to treat 64 patients with primary trigeminal neuralgia,achieving successful entry into the foramen ovale and enabling selective ganglion radiofrequency thermo-coagulation.The patients were followed for 1 week to 12 months,with an average of(6.0±1.9)months,and reported treatment satisfaction and no recurrence.Conclusion The application of CT-guided percutaneous lateral perforation technique provides a new and feasible therapeutic approach for treating trigeminal neuralgia by selective radiofrequency thermocoagulation of the semilunar ganglion.
