title: Auditory symptoms associated with herpes zoster or idiopathic facial paralysis.
abstract: Auditory symptoms (hyperacusis, tinnitus, decreased hearing) have long been recognized to accompany herpetic or idiopathic facial paralysis. Twenty-nine percent of 1,080 patients with idiopathic facial paralysis and 37 percent of 172 with herpes zoster oticus facial paralysis had auditory symptoms. Abnormal related sensori-neural hearing loss was documented in only 11 of these 377 patients with auditory complaints. All of the 11 had a diagnosis of herpes zoster oticus. Sensori-neural hearing loss occurs in only about 6.5 percent of patients with herpes zoster facial paralysis, and no confirmed case of such loss in idiopathic facial paralysis has been reported. In patients presenting with sensori-neural hearing loss accompanying facial paralysis believed to be idiopathic, herpes zoster should be suspected even in the absence of vesicles. Factors favorable for recovery of auditory function include age 64 years or younger, mild initial hearing loss, a cochlear pattern of hearing loss, and absence of vertigo. Recovery of auditory function does take place; however, a high-tone sensori-neural loss may persist except in younger patients.
