Cortical Auditory Evoked Potentials

Infants with auditory neuropathy and possible hearing impairment are being identified at very young ages through the implementation of hearing screening programs. The diagnosis is commonly based on evidence of normal cochlear function but abnormal brainstem function. This lack of normal brainstem function is highly problematic when prescribing amplification in young infants because prescriptive formulae require the input of hearing thresholds that are normally estimated from auditory brainstem responses to tonal stimuli. Without this information, there is great uncertainty surrounding the final fitting. Cortical auditory evoked potentials may, however, still be evident and reliably recorded to speech stimuli presented at conversational levels. The case studies of two infants are presented that demonstrate how these higher order electrophysiological responses may be utilized in the audiological management of some infants with auditory neuropathy. Los niños con neuropatía auditiva y posibles posibles trastornos auditivos están siendo identificados a edades tempranas con la implementación de programas de tamizaje auditivo. El diagnóstico se basa en la evidencia de una función coclear normal pero de una función anormal del tallo cerebral. Esta falta de función normal de tallo cerebral es muy problemática cuando se trata de prescribir amplificación en niños pequeños, porque las fórmulas de prescripción requieren el insumo de los umbrales auditivos que se estiman normalmente a partir de las respuestas del tallo cerebral ante estímulos tonales. Sin esta información, existe una gran incertidumbre en cuanto a la adaptación final. Los potenciales evocados auditivos corticales pueden, sin embargo, registrarse con confiabilidad a partir de estímulos de lenguaje presentados a niveles de intensidad para la conversación. Se presenta el estudio de dos casos de niños, que demuestran como estas respuestas electrofisiológicas de orden mayor pueden utilizarse en el manejo audiológico de algunos niños con neuropatía auditiva.
