Masking Treatment and its Effect on Tinnitus Parameters

Area of Science:

• Audiology
• Otolaryngology
• Neurology

Background:

• Tinnitus, the perception of sound without external stimuli, has complex pathophysiology and lacks definitive treatments.
• Auditory pathway disorders or systemic conditions can cause tinnitus.
• Tinnitus masking therapy is a recognized treatment modality.

Purpose of the Study:

• To prospectively evaluate the efficacy of tinnitus masking therapy on tinnitus parameters.
• To assess changes in tinnitus-related distress and handicap post-treatment.

Main Methods:

• Sixty-six patients with normal physical exams and audiological tests were enrolled.
• Participants completed questionnaires including the Tinnitus Handicap Inventory (THI) and Beck Depression Inventory (BDI).
• Tinnitus parameters (frequency, intensity, masking levels, residual inhibition) were measured before and after four weeks of masking treatment.

Main Results:

• Masking therapy led to a significant reduction in Tinnitus Handicap Inventory (THI) and Visual Analog Scale (VAS) scores.
• Twenty patients (approximately 30%) did not respond to the four-week treatment.
• Improvements were observed in tinnitus parameters after the treatment period.

Conclusions:

• Tinnitus masking therapy is an effective, non-invasive, and cost-effective treatment option.
• The therapy provides significant symptom reduction in tinnitus patients, particularly in the short term.
• Masking therapy holds an important place in the management of tinnitus.
