[Contribution of EMG to the diagnosis of facial nerve and muscle involvement in neurinoma of the VIIIth nerve].
An examination of 5 cases of acoustic nerve neurinoma, and 3 cases where the diagnosis was suspected, showed that EMG signs of a possible facial nerve compression in the ponto-cerebellar angle were represented by abnormal activity at rest, sub-clinical signs of progressive neurogenic atrophy in the hemi-facial muscles, and a significant increase in the latency of the oligosynaptic R1 reflex response.
