[Viral infection and ear diseases].

The association of viral infection to ear disease has triggered a great deal of interests. In the present paper, we provide a critical review of the viral hypothesis of ear diseases. Detection of viral antigen and antibody or RNA and DNA in the patients serum, endolymphatic fluid or surgical pathology specimens reveals that virus may have relevance to certain kinds of ear diseases, such as Meniere's disease, idiopathic sudden sensorineural hearing loss, otosclerosis. Bell's palsy and otitis media. The most appealing is the herpesvirus, which can cause latent infection in the neurons, and its reactivation may be the mechanism of recurrent attacks of ear diseases. Currently, antiviral drug treatment plus supportive therapy are the most effective managements dealing with viral infection. Although antiviral vaccine will become a promising preventive strategy in the future.
