The effects of congenital cytomegalovirus infection vary from severe central nervous system destruction to asymptomatic viuria. Yet children with the latter have a high incidence of unsuspected hearing loss. Histopathology of temporal bones from children who die with cytomegalic inclusion disease shows viral infected cells in non‐sensory endolabyrinthine epithelium. Experimental mouse cytomegalovirus causes an age related cranial neuronitis and perilabyrinthitis. Immunopathologic localization of different viral antigens in experimental inner ear infections shows differential vulnerability of labyrinthine structures to infections. Adaptation of such techniques to human temporal bone, pathology could yield information regarding pathogenesis of viral labyrinthitis. The development of a human cytomegalovirus vaccine may eliminate the risks of this congenital infection.
