Hearing aid effectiveness on patients with chronic tinnitus and associated hearing loss()

OBJECTIVE: Our study aimed to measure the effectiveness of using HA in reducing the disturbance caused by tinnitus. METHODS: Study was designed as a within-subjects clinical trial. Nineteen patients with chronic tinnitus and untreated sensorineural hearing loss were under counseling, HA fitting and 6 months follow-up. Tinnitus assessment was performed with Tinnitus Handicap Inventory (THI), Visual Analog Scale (VAS), pitch and loudness matching, and Minimum Masking Level measurements (MML). RESULTS: following 6 months of HA use, a reduction in reported tinnitus and hearing handicap scales scores was observed both statistically and clinically. The pitch and loudness matching, as well as MML at the baseline and final evaluation were compared. MML’s thresholds reduced significantly after 6 months of HA use. CONCLUSION: Our study has provided evidence that HA fitting is a valuable treatment strategy for chronic tinnitus relief and associated hearing loss subtype of patient. LEVEL OF EVIDENCE: 3.
