The spectrum of diseases diagnosed and the protocol used in the investigation
of 53 patients with unilateral sensorineural hearing loss is
presented. The diagnostic tests found most useful in defining the site of
the lesion were a combination of auditory brainstem response (ABR) and
electrocochleography (ECoG). Laboratory investigations were important to
diagnose the viral and vascular etiologies.
We recommended vaccination against infectious diseases, which are
responsible for this kind of hearing problem. Each patient with unilateral
sensorineural hearing impairment. regardless of type of onset. regardless
of how long it have been present and regardless of how apparent the etiology
may be, should be evaluated to rule out an acoustic tumor. |
