Preparalytic condition of the facial nerve detected by evoked electromyography.
An abnormal condition of the facial nerve just before apparent paralysis was detected by evoked electromyography. We now report on 2 patients with herpes oticus and vertigo or tinnitus without apparent facial palsy. This abnormal condition is considered to be a subclinical paralysis (preparalytic condition), and early detection of the condition may prevent ensuing paralysis.
