AAEM CASE REPORT-26 - 7TH CRANIAL NEUROPATHY

A 25-year-old man with acute, bilateral facial palsies is presented. He had a lymphocytic meningitis, history of tick bites, and lived in an area endemic for Lyme disease, which was ultimately confirmed by serology. Electrodiagnostic investigation included facial motor nerve study, blink reflex and electromyography of facial muscles, which were indicative of a neurapraxic lesion on the right and an axonopathic lesion on the left. The clinical course was consistent with these findings as the right side fully recovered and the left remained plegic. The clinical features of Lyme associated facial neuritis are reviewed, as is the electrodiagnostic evaluation of facial palsy.
