Abstract: 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.

Key words: Electrical neurography, Blink reflex, Facial palsy
