case_images: The activity of the right facial nerve in the repetitive nerve stimulation test was decreased. (A) The amplitude of the fifth wave was 30% lower than that of the first wave when the right facial nerve was stimulated at 3 Hz repetition frequency. (B) The amplitude of the fifth wave was 34% lower than that of the first wave when the right facial nerve was stimulated at 5 Hz repetition frequency.

case_images: The repetitive nerve stimulation test showed that the amplitude of the low-frequency stimulation of right facial nerve progressively decreased (3 Hz 30%, 5 Hz 34%) (Figure 1).
