Tinnitus sound therapy with open ear canal hearing aids.B-ENT. 2010; 6(3):195-9.B
The aims of this study were to evaluate the efficacy of open ear canal hearing aids in tinnitus treatment and to investigate the influence of gender, age, medication usage, tinnitus cause, tinnitus perception side, tinnitus pitch, pure tone audiometry, distortion product otoacoustic emissions, and minimal masking level on outcome.
One hundred tinnitus patients were evaluated by the tinnitus handicap inventory (THI) at the beginning of the study and after nine months of treatment. All subjects were submitted to counselling and sound enrichment from the simple sound amplification provided by the open ear canal hearing aids.
Initial mean THI score was 54.22 (+/- 20.37) and final mean score was 28.32 (+/- 16.50), p < 0.0001. No statistically significant correlations were found between THI value reduction and the studied parameters.
Open ear canal hearing aids were useful in all tinnitus patients with mild hearing loss.
