摘　　要：目的:探讨交互式Mimics有限元分析软件在半月神经节射频术治疗三叉神经痛中的临床价值。方法:选取我院原发性三叉神经痛住院患者180例,VAS评分≥8分,随机分为2组(n=90):Mimics组(M组)和CT组(C组)。C组以患者术前颅底CT影像分析卵圆孔形态;M组通过Mimics有限元分析软件对患者头颅CT影像进行重建和分析,比较2组穿刺的成功率、并发症和治疗效果。结果:M组穿刺成功率为100%,C组为92%(P<0.05)。穿刺过程中C组6例发生血肿,1例误入口腔,M组无一例出现穿刺并发症,2组比较差异有统计学意义(P<0.05)。C组术后VAS评分(1.6±0.3)分,M组术后VAS评分(1.3±0.4)分,2组比较差异无统计学意义(P>0.05)。结论:Mimics有限元分析软件能提高颅底卵圆孔穿刺的成功率并有效减少穿刺的并发症发生率,故能安全应用于半月神经节射频术治疗原发性三叉神经痛。Objective To observe the efficacy of Mimics finite element analysis software in the gasserian ganglion radiofrequency treatment of trigeminal neuralgia. Methods 180 cases with primary trigeminal neuralgia and VAS score ≥8 were randomly divided into 2 groups （n = 90 each）： CT group （group C） and Mimics group （group M）. The preoperative skull CT image of the foramen of cranial base could be analyzed in group C. The preoperative cranial CT image could be reconstructed and analyzed by Mimics finite element analysis software in group M. The puncturing success rate, complications rate and the outcomes between two groups were recorded. Results The puncturing success rates were 100% in group M and 92% in group C （P ＆lt; 0.05）. 6 cases with hematoma and 1 case, which were stabbed into the oral cavity were found in group C. No puncture complication was found in group G. There was no statistically significant between the two groups （P ＆lt; 0.05）. The VAS score was 1.6 ＆#177; 0.3 in group C and 1.3 ＆#177; 0.4 in group G, there was no statistical significance （P ＆gt; 0.05） between them. Conclusions The Mimics finite element analysis software could improve the success rate of basicranial foramen ovale puncture and reduce the occurrence rate of puncture complications. Therefore , it could be safely applied to the treatment of primary trigeminal neuralgia by gasserian ganglion radio frequency.
