[Solitary hearing and equilibrium damage after vaccinations].

Solitary impairments of hearing and equilibrium after vaccinations are rarely seen. They are usually connected with damage to the central nervous system, thus being combined with further neurological symptoms. In German and English literature 9 cases of isolated statoacoustic nerve lesions due to vaccinations could be found. They are summarized and their similarities and differences are discussed. Information relevant for the evaluation of possible causal relations between vaccinations and solitary 8th cranial nerve disorders is emphasized. Questions concerning the incidence, etiology and differential diagnosis of functional cochleovestibular impairments are highlighted.
