Resumen

Se realiza un estudio con potenciales evocados auditivos de tronco cerebral en 50 recién nacidos que no han pasado el examen con otoemisiones acústicas transitorias evocadas. 27 neonatos (54%) no refieren antecedentes familiares de hipoacusia neurosensorial ni están incluidos en los grupos de riesgo. Verificamos ausencia de registro de PETC en 35 (70%) de los 50 bebés examinados. Durante su seguimiento confirmamos normoaudición en 21 (60%) y distinto grado de disfunción auditiva en 14 (40%). Necesitamos un intervalo de tiempo comprendido entre uno y nueve meses para llevar a cabo un diagnóstico definitivo.

Palabras clave:
Examen auditivo
Potenciales auditivos
Disfunción auditiva

Abstract

Auditory Brainstem Response (ABR) of 50 newborn with negative transient evoked acoustic emissions (OEAT) was performed. 54% of them had no family history of sensorineural hearing loss (SHNL) and no risk factors were found. In 70% of cases ABR recording was negative. Follow up did show that 60% of them had normal recordings of hearing and in a 40% different stages of hearing loss were seen. To establish a definitive diagnosis a 1 to 9 month period is necessary.
