Table 1. Average Numerical Audiometric Results Obtained by Free Field Tonal Audiometry.
Abstract

We included 9 patients implanted with Baha® Attract. All our patients were evaluated by free field tonal audiometry, free field verbal audiometry and free field verbal audiometry with background noise, all the tests were performed with and without the device. To evaluate the subjective component of the implantation, we used the Glasgow Benefit Inventory (GBI) and Abbreviated Profile of Hearing Aid Benefit (APHAB).

The auditive assessment with the device showed average auditive thresholds of 35.8dB with improvements of 25.8dB over the previous situation. Speech reception thresholds were 37dB with Baha® Attract, showing improvements of 23dB. Maximum discrimination thresholds showed an average gain of 60dB with the device.

Baha® Attract achieves auditive improvements in patients for whom it is correctly indicated, with a consequent positive subjective evaluation. This study shows the attenuation effect in transcutaneous transmission, that prevents the device achieving greater improvements.

Resumen

Se incluyeron en el estudio 9 pacientes implantados con el dispositivo Baha® Attract. A todos los pacientes se les realizó, con y sin el dispositivo, una audiometría tonal en campo libre, una audiometría verbal en campo libre, y una audiometría verbal con ruido de fondo, así como la aplicación de los cuestionarios Glasgow Benefit Inventory (GBI) y Abbreviated Profile of Hearing Aid Benefit (APHAB).

Las valoraciones audiológicas con el dispositivo mostraron unos umbrales auditivos promedios de 35,8dB, con ganancias medias de 25,8dB. El umbral de recepción verbal promedio con el dispositivo se situó en 37dB, mostrando una ganancia de 23dB. Los resultados promedio del umbral de discriminación máxima fueron de 60dB con el dispositivo.

El Baha® Attract logra alcanzar unas ganancias auditivas en los pacientes indicados correctamente, con una consiguiente valoración subjetiva positiva por parte de los pacientes, presentando no obstante un efecto atenuativo en su transmisión transcutánea, que le impide alcanzar mayores ganancias.
