Estudio electrofisiológico y electroacústico de un desorden del espectro de neuropatía auditiva: Reporte de un caso en recién nacido de alto riesgo

auditory neuropathy spectrum disorder (ansd) describes a condition in which it is possible to find otoacoustic emissions (oae) in presence of abnormal or absent auditory brainstem evoked potentials (abr). the pure tone thresholds may show a spectrum from normal to profound hearing loss. speech recognition is often affected in presence of background noise, but in some individuals remains intact. we report a case of a pre term newborn (female) of 29 weeks and 810 grams, apgar 7/8, bronchopulmonary dysplasia, suspected connatal infection, and hyperbilirubinemia (max 11 mg / dl). she was referred to hospital padre hurtado for hearing assessment. the hearing test performed were an abr, tympanometry & acoustic reflex, visual reinforcement audiometry and otoacoustic emissions. the results are consistent with those described in the literature for ansd.
