Abstract

As part of a quality of life study, 84 patients who received multichannel intra-cochlear cochlear implants (CIs) were evaluated regarding tinnitus problems by a questionnaire. As controls, 60 hearing aid (HA) users and 35 non-operated CI candidates were used. The prevalence of tinnitus in the CI group was 70%, and that of troublesome tinnitus was 35%. In the two other groups, the prevalences of tinnitus were 40% (HA) and 74% (non-CI). Twenty-three per cent of HA users and 51% of non-operated CI candidates had troublesome tinnitus. CIs were found to be superior to HAs in reducing tinnitus, 54% of the CI patients with tinnitus experiencing a reduction in tinnitus when using a CI. In the other two groups, 4% of HA users and 23% of non-operated CI candidates experienced a reduction in tinnitus when using an HA. Eight per cent of the CI patients with tinnitus experienced an increase in tinnitus when using their implant. Not having paid employment was independently associated with troublesome tinnitus in all three groups.
