【摘要】 目的观察茎乳孔面神经阻滞治疗面肌痉挛的疗效。方法选择原发性单侧面肌痉挛患者36例,采用茎乳孔穿刺法常规穿刺成功后,先后注入2%利多卡因、地塞米松和2%泛影葡胺,行头颅螺旋CT扫描。结果CT显示,27例患者造影剂最终显影于面神经转折处,即膝状神经节处,9例显示造影剂达内耳道底附近。面肌痉挛强度及频率在治疗后各时期无显著性差异(P>0.05),但与治疗前相比,则有极显著性差异(P<0.01)。造影剂到达的深度与患者3个月后的痉挛强度、痉挛频率之间无显著性差异(P>0.05)。所有患者治疗2周到3个月间,面部自主运动均恢复。结论茎乳孔面神经阻滞机理主要是作用于面神经骨性管道内的血管扩张、炎性渗出等。对面肌痉挛有确实可靠的疗效。更多还原

【Abstract】 Objective To observe the effect of facial nerve blockage on hemifacial spasm. Method Thirty-six patients with hemifacial spasm were successfully punctured and injected with 2% lidocaine,dexamethasone and 2% metrizamide.Computerized Tomographywas done afterwards. Results Metrizamide was shown at the turning point of the facial nerve in 27 patients and was shown near the bottom of internal auditory meatus in the others.There was a significant difference in intensityand frequency between before and after treatment.There was no relationship between the deep of metrizamide and the effect of treatment.Conclusion The mechanism of this treatment is to working on the dilatation of the blood vessel and the exudative inflammation.更多还原
