[Cytomegalovirus infection and inner ear deafness].

Bilateral sensorineural hearing loss of patients is correlated with elevated antibody titres against cytomegaly virus in serum in children as well as in adults. Unilateral deafness correlates with mumps infection. This is shown in a German population as well as in a Mediterranean group of patients. There is no evidence between antibody titer of Coxsackie virus, adenovirus and herpes virus or toxoplasma gondii interaction and sensorineural hearing loss neither unilaterally nor bilaterally.
