Terapia de reentrenamiento (TRT) en el acúfeno de la enfermedad de Ménière

Abstract

To evaluate the response of tinnitus in Meniere's disease patients (MD) using the Tinnitus Retraining Therapy (TRT). This management includes a wide cognitive medical counselling and natural or prosthetic sound therapies (hearing aid or noise generator). Descriptive prospective study (EBM level 3). Twenty-five patients diagnosed as definitive MD (AAO-HNS 95 criteria) were enrolled in our tinnitus protocol. Tinnitus changes were reported according to patient's self-evaluation, a visual analogue scale on tinnitus intensity (EVA) and the Tinnitus Handicap Inventory (THI). Seventy-three percent of the patients improved their tinnitus after 6 months of treatment (p < 0.05). THI scores were reduced from the initial 47% to 24% (p < 0.05) and EVA from 6.6 to 5.2 (p < 0.05). After 12 months, the response was slightly worse: 68% improved according to their self-evaluation (p < 0.05), THI score reached 20% (p < 0.05) but EVA did not improve significantly (6.4). Patients that refused prosthesis adaptation (hearing aid or noise generator) did not improved and the THI score (48%) and EVA score (6.6) did not change. TRT has proved to be an effective method for tinnitus treatment in MD that improves patient's self-evaluation, tinnitus loudness and handicap scores. Individualized medical counselling and an exhaustive prosthesis adaptation are crucial to guarantee satisfactory results.
