摘　　要：①目的 探讨采用极性交替的电刺激方法逆行诱发电位刺激伪速减小的可行性。②方法 刺激面神经外周分支,在健康家猫鼓膜记录面神经送行诱发电位。③结果 在鼓膜记录到面神经逆行诱发电位受刺激伪迹影响减小,而不影响面神经逆行诱发电位的波形。④结论 采用极性交替的电刺激方法,记录面神经逆行诱发电位,既可减小了刺激伪迹,也不影响其波形,且便于结果分析,可在人体面神经逆行诱发电位检查中推广应用。Objective To investigate alternative polarity stimulation applied in facial nerve antidromical evoked potentials (FNAEP). Methods With alternative polarity stimulation of the peripheral segment of the facial nerve at stylomastoid foramen in cats, and recording of FNAEP by an electrode at the tympanic membrane. Result FNAEP recorded at the tympanic membrane showed precisely and declined the stimulus artifact. Conclusion Alternative polarity stimulation applied in order to reduce the stimulus artifact and to analyze precisely the waveform of facial nerve antidromical evoked potentials (FNAEP).
