瞬目反射及面神经电图在Bell面瘫中的临床应用

目的 研究瞬目反射(blink reflex, BR)及神经电图(electrical neurography, ENG)在Bell面瘫中的应用价值。方法 采用海神号神经检诊仪，刺激眶上神经，分别在同侧眼轮匝肌记录出R1波及R2波，在对侧眼轮匝肌记录出R′2波；在茎乳孔处刺激面神经，用同心圆针电极记录出运动潜伏期及M波波幅，对35例Bell面瘫患者行BR及ENG检测，并与自身健侧对比。结果 35例患者BR均有不同程度异常，ENG部分异常。结论 BR与ENG均能反映面神经损伤程度、部位及预后，两者结合的早期诊断及预后判断价值更大。

Blink reflex and electrical neurography in the clinical evaluation of Bell's facial palsy

Objective To explore the effects of the blink reflex（BR） and electrical neurography（ENG） in the evaluation of Bell′s facial palsy. Method Haishen nerve examination instruments were used to stimulate the super-orbital nerve to record wave R１and R２ of the ocular orbicular muscle in the same sides and wave R２ of the ocular orbicular muscle in the opposite sides. A concentric needle electrode was used to stimulate the facial nerve to record the latent phase of movement and the scope of wave M. Also the BR and ENG were determined and compared with the controls. Result BR was abnormal in 35 cases of Bell′s facialpalsy in different degrees, and ENG was abnormal in some of the cases. Conclusions Both BR and ENG can reflex the degree, location and prognosis of the facial nerves.BR is more important in early diagnosis and prognosis than ENG，but their combination is more valuable than when only one is used.
