Objective: This paper aimed to evaluate the effectiveness of the 3D printing puncture navigation template-guided percutaneous radiofrequency thermocoagulation for V2 trigeminal neuralgia treatment.
Methods: A total of 52 patients with V2 trigeminal neuralgia were treated with radiofrequency thermocoagulation. A total of 32 patients were treated under the guidance of the 3D printing puncture navigation template (guide plate group), while 20 patients underwent puncture via pterygopalatine fossa routinely (routine treatment group). The puncture time, operation time, puncture success rate, and immediate postoperative pain were recorded. The degree of immediate postoperative pain was indicated by visual analogue scale (VAS). Barrow Neurological Institute (BNI) classification criteria were used to evaluate the efficacy, and the postoperative complications were observed. All patients were followed up for 1 year.
Results: The two groups showed significant decrease in VAS after the operation (P<0.05). The puncture and operation times of the guide plate group were significantly lower than those of the routine treatment group (P<0.05). The difference in terms of the clinical effects and recurrence rate between the two groups was insignificant (P>0.05).
Conclusions: 3D printing puncture navigation template-guided radiofrequency thermocoagulation may increase the operation success rate and reduce complication incidence. Therefore, this technique possesses clinical promotional value.
目的 评价3D打印导板辅助射频温控热凝术治疗原发性第2支三叉神经痛的临床疗效。方法 对52例采用射频温控热凝治疗的原发性第2支三叉神经痛患者进行临床随访研究，其中32例采用3D打印导板辅助穿刺（导板组），20例采用常规经翼腭窝穿刺（常规组），记录两组患者的术中穿刺操作时间、手术时间、穿刺成功率、术后即刻疼痛程度（VAS），采用巴曼神经学研究所分级标准对术后疗效进行评估，并记录术后并发症的情况。随访时间为1年，观察疗效。结果 与术前比较，两组患者术后即刻疼痛均明显缓解，差异均有统计学意义（P<0.05）；导板组患者的穿刺操作时间、手术时间明显短于常规组，穿刺成功率高于常规组，差异有统计学意义（P<0.05）。根据BNI分级标准，两组患者术后治疗效果的差异无统计学意义（P>0.05）。结论 3D打印导板辅助射频温控热凝术治疗原发性第2支三叉神经痛，可提高手术成功率，减少手术并发症，具有临床推广价值。.
