“Facial nerve motor evoked potentials are confirmed.”

“The left brainstem auditory evoked potential has a slightly low amplitude, but the waveform is confirmed.”

Because the left hearing had been reduced even before surgery, the amplitude was small.

Care must be taken during surgery so that Myeong In-su…
