伽玛刀治疗原发性三叉神经痛神经根影像暴露长度与疗效的关系分析

Curative Effect Analysis for the Measure of Trigeminal Radix at MRI on Gamma Knife for Trigeminal Neuralgia

目的：探讨伽玛刀治疗原发性三叉神经痛时,三叉神经根在定位影像上的暴露长度与疗效之间的关系。方法：整理我中心2000年12月-2006年6月间采用相似手段治疗、随访的原发性三叉神经痛患者91例,测量总结MR定位影像上三叉神经根显露长度与疗效之间的关系。结果：病人特征、性别、年龄、病程、随访时间等因素与各组间的随访结果无统计学意义（P〉0.05）。各组之间,神经根暴露长度与疼痛缓解率呈正相关（P〈0.05）。结论：三叉神经根显露长度越长有效率越高。

Objective：To research the correlation between curative effect and the measure of trigeminal radix at MRI on gamma knife for trigeminal neuralgia.Methods：To summarize 91 patients of trigeminal neuralgia at the time of we treated alike with gamma knife in Dec.2000 and Jun.2006,surveyed the length of trigeminal radix at MRI and research the correlation between curative effect and the measure.Results： There is positive correlation between the measure of trigeminal radix of MRI and the curative effect with gamma knife（P〈0.05）.The measure of trigeminal radix at MRI is irretative of curative effect.Conclusion：There is a positive correlation between the measure of trigeminal radix at MRI and the curative effect with gamma knife.
