ABSTRACT |
It is known that hearing aids can be effective in treating patients with both tinnitus and hearing loss. The aim of this study was to disclose
the specific effects of hearing aids in relieving tinnitus and to find out relevant prognostic factors. A prospective study was done
on 10 patients who had both tinnitus and hearing loss. All the patients underwent tinnitus evaluation, such as pitch & loudness matching,
minimal masking level (MML) and residual inhibition (RI). Also self-reported outcome measures of tinnitus and hearing handicap
such as visual analog scale (VAS), tinnitus handicap inventory (THI), hearing handicap inventory for the elderly (HHIE) and
tinnitus intake/outcome interview (TI) were investigated. A success rate of tinnitus control was 90.0% in VAS and 70.0% in THI. The
alleviation rate was 53.2% in VAS, 48.0% in THI and 50.0% in TI. The characteristics of the tinnitus such as MML and RI changed
during three months of hearing-aids use. Each score of the VAS, THI, HHIE and TI before the treatment had a significant correlation
with the total THI score after 3 months of the treatment. The duration of tinnitus had a significant correlation with the change in RI.
After using hearing aids, the subjective discomfort due to tinnitus significantly reduced in 70-90% of the patients. The most important
prognostic factor was the degree of pretreatment discomfort. Therefore, a more substantial improvement would be expected
from the patients with greater pretreatment discomfort level. |
