Article information

In this study we present a case of a 71-year-old female patient with sensorineural hearing loss and fitted with bilateral hearing aids. The patient complained of scant benefit from the hearing aid fitting with difficulties in understanding speech with background noise. The otolaryngology examination was normal. Audiological tests revealed bilateral sensorineural hearing loss with threshold values of 51 and 50 dB HL in the right and left ear. The Dichotic Digit Test was administered in a divided attention mode and focalizing the attention to each ear. Results in this test are consistent with a Central Auditory Processing Disorder.

Central auditory processing

Mujer de 71 años diagnosticada de hipoacusia neurosensorial bilateral. Se llevó a cabo adaptación audioprotésica en ambos oídos. Menciona que a pesar de la amplificación nota dificultades para la comunicación, especialmente en ambientes ruidosos. La exploración otorrinolaringológica está dentro de los límites normales. El estudio audiométrico concuerda con umbrales de 51 y 50 dB HL en los oídos derecho e izquierdo respectivamente. Los resultados en el test de dígitos dicóticos en modalidad de atención dividida y focalizada son compatibles con un trastorno del procesamiento auditivo central.
