Hearing aids and tinnitus therapy: a 25-year experience

Area of Science:

• Audiology
• Otolaryngology
• Hearing Science

Background:

• Tinnitus is a common symptom associated with hearing loss.
• Hearing aids are frequently prescribed to manage tinnitus.
• The efficacy of digital hearing aids for tinnitus management requires further investigation.

Purpose of the Study:

• To evaluate subjective tinnitus perception before and after hearing aid provision in patients with hearing loss.
• To compare tinnitus perception between patients with unilateral and bilateral hearing loss.
• To assess the impact of a digital hearing aid program on tinnitus perception.

Main Methods:

• Prospective data collection over 25 years (1980-2004) at a university teaching hospital tinnitus clinic.
• Inclusion of 2153 consecutive patients with audiologically proven hearing loss.
• Assessment of tinnitus improvement using a visual analogue scale, comparing analog and digital hearing aids.

Main Results:

• 1440 patients received hearing aids (826 unilateral, 614 bilateral).
• 67% of unilaterally aided and 69% of bilaterally aided patients reported tinnitus improvement.
• Digital hearing aids showed a statistically significant improvement in tinnitus perception (p < 0.001) compared to analog aids.

Conclusions:

• Hearing aid provision is crucial for tinnitus control in patients with hearing loss.
• Programmable digital hearing aids provide an additive benefit for tinnitus management.
• The study highlights the evolving role of hearing aid technology in improving tinnitus outcomes.
