Audiological manifestations of Ramsay Hunt syndrome

Ramsay Hunt syndrome is known to cause audiological signs and symptoms, including sudden, unexpected hearing loss. We carried out a retrospective review of the audiological manifestations of 186 patients with Ramsay Hunt syndrome, measuring their hearing loss patterns, hyperacusis, tinnitus, herpetic rash, facial paralysis, pain and vertigo. Statistical correlations of these parameters were equated with prognosis. Prognosis for eventual hearing recovery is, in general, excellent. Prognostic indicators of poor hearing recovery include advanced age, retrocochlear hearing loss, male gender, vertigo, and speech frequency hearing loss.
