【摘要】 目的 :探讨三叉神经根的解剖学结构 ,为三叉神经痛 (TN)的治疗提供形态学的依据。方法 :从尸体 (10具 )上取三叉神经根标本 ,对三叉神经感觉根 (TNSR)进行石蜡包埋及连续切片 ,并系统观察 ;对 2例TN患者行TNSR表层神经纤维束切断术及随访。结果 :解剖及组织学上显示了TNSR的中央部分有一根巨大的神经纤维束 ,而在表层环绕着细小的神经纤维束。术中观察与组织学一致 ,2例TN患者术后 ,随访 >1 5年 ,未复发。结论 :TNSR表层神经纤维束切断术治疗TN方法可行。更多还原

【Abstract】 Objective: To investigate the anatomic structure of trigeminal nerve root and provide the morphologic base for the treatment of trigeminal neuralgia(TN). Methods:Two trigeminal nerve root and the trigeminal nerve sensory root(TNSR) were obtained from 10 anatomic cadav ers and were paraffin embedded. Clinically, 2 patients with TN were operated on using the new TNSR tractotomy,in which only surface nerve fiber bundles of TNSR were cut. Results: Histologically, it was composed that many tiny nerve fiber bundles located in the surface layer and a big nerve fiber bundle in the center of the root in the TNSR. Clinically, observation on the TNSR structure during the operation was consistent with the in vitro histological findings. Two patients were followed up for 18 months and more, no recurrence. Conclusion:The technique for TN operated with TVSR tractotomy is feasible.更多还原
