Abstract

Abstract

Objective: In this study, we aimed to explore a variation of the NTT standard protocol that would be more beneficial for those patients with hearing loss >50 dB HL in the worst ear (average hearing thresholds at 0.5, 1, 2, and 4 KHz). Study sample: This study involved 26 subjects who had previously undergone NTT at a single private practice. Design: Patients with high level of hearing loss were divided into two groups: Standard protocol group (SP) concluded the treatment following the standard NTT protocol proposed by the treatment's developers and Neuromonics guidelines. Extended protocol group (EP) was treated using a variation of the standard protocol, in which patients continued in stage 1 of the treatment for a prolonged time. Consistent with previously reported studies of the NTT, the tinnitus reaction questionnaire was used to assess tinnitus distress. Clinical outcomes for the two groups were analysed. Results: Both groups achieved statistically significant improvement of their tinnitus distress. EP group achieved quicker clinical benefits when compared to the SP group. Conclusions: Extension of high stimulation period from two to four months may be beneficial for patients with higher level of hearing loss undergoing NTT.

Sumario

Objetivo: En este estudio nuestro objetivo fue explorar la variación del protocolo estándar del NTT que puede ser más benéfica para los pacientes con una hipoacusia >50 dB HL en el peor oído (promedio de umbrales de audición a 0.5, 1, 2 y 4 KHz). Muestra: Este estudio incluyó a 26 sujetos que previamente habían recibido NTT en una sola clínica privada. Diseño: Los pacientes con una hipoacusia importante fueron divididos en dos grupos: el grupo del protocolo estándar (SP) concluyó el tratamiento siguiendo el protocolo NTT estándar propuesto por quienes desarrollaron las guías de Neuronomics. El grupo del protocolo extendido (EP) fue tratado utilizando una variación del protocolo estándar en el que los pacientes continuaron en el estadio 1 del tratamiento durante un tiempo prolongado. En concordancia con los resultados previamente reportados del NTT, se aplicó el cuestionario de reacción al acúfeno para evaluar la angustia por el mismo. Se analizaron los resultados clínicos de los dos grupos. Resultados: Ambos grupos alcanzaron una mejoría estadísticamente significativa del la angustia por el acúfeno. El grupo EP alcanzó el beneficio clínico más rápidamente comparado con el grupo SP. Conclusiones: La extensión del periodo de alta estimulación de dos a cuatro meses puede beneficiar a los pacientes con un nivel alto de hipoacusia que reciben NTT.
