Abstract
Introduction: tinnitus can affect the quality of life of a patient. Acoustic stimulation can be used as treatment when the cause of tinnitus is located in the cochlea.
Objective: Determine change in tinnitus perception before and after therapeutic intervention.
Methodology: We performed a case series study. Patients with non-pulsatile tinnitus, with no improvement with medical therapy, and grade moderate- catastrophic were treated with the REVE 134™ system. A microaudiometry (67 frequencies) was performed to determine the cochlear regions affected. Patients with auditory thresholds >60 dB, retrocochlear pathologies, and who did not want to participate in the study were excluded. The variables studied were THI (“Tinnitus Handicap Inventory”), VAS (Visual Analog Scale) and TQR (“Tinnitus Reaction Questionnaire”), that were measured before, three, and six months after treatment.
Results: 11 patients (male: 5, women: 6) were included. In 5 of them tinnitus was bilateral, and in 6 unilateral. Pretreatment values were: THI=61.4±27.4, VAS=6.9±2.7 and TQR=43.2±31.9 (Kolmogorov-Smirnov, p>0.05). We found improvement in tinnitus perception with the therapy, and this values had statistical significance (THI (3mo=30.6±21.1; 6mo=19±19.2), VAS (3mo=5.6±2.3; 6mo=3.5±2.0), TQR (3mo=25.6±20.0; 6mo=14.3±19.9); repetitive measures of ANOVA (p=0.007, p=0.027, p=0.037; respectively)).
Conclusion: Treatment with REVE 134™ was effective in patients with moderate to catastrophic tinnitus.
