神经导航下射频热凝治疗三叉神经痛的临床研究

目的：探讨神经导航系统在三叉神经痛的射频热凝治疗中的应用。方法：患者术前行CT薄层扫描，将影像学资料输入神经导航系统，将卵圆孔等重要结构标记后行三维重建，在导航引导下进行卵圆孔穿刺后行射频热凝治疗。结果：术中卵圆孔穿刺准确率达100%，术后即刻疗效，优良9例 良好6例，无严重并发症。结论：神经导航术在三叉神经痛射频热凝治疗中的应用提高了穿刺卵圆孔的精确率，减少了手术并发症。

Neuronavigatio-guided percutaneous radio-frequency thermo-coagulation in treatment of intractable trigeminal neuralgia

Objective: To investigate the effects of neuronavigatio in radio-frequency thermo-coagulation for trigeminal neuralgia.Methods: Patients with trigeminal neuralgia had continuous and thin-slice CT scans before surgery.The CT data were transported to the neuronavigation system.Being marked and reconstructed in three dimensions,the oval foramen was punctured under neuronavigation and radio-frequency thermo-coagulation was then performed on the patients.Results: The oval foramen was smoothly and accurately punctured under neuronavigation in all.Pain was eliminated in 9 cases and alleviated in 6 cases.No serious complications occurred.Conclusion: Neuronavigatio-guided radio-frequency thermo-coagulation is successful in puncturing the oval foramen and reducing the incidence of complications for trigeminal neuralgia.
