RESUMO
According to statistics, hyperbilirubinemia is observed during the first week of life in approximately 60% of full-term and 80% of premature newborns. It is known that indirect bilirubin has a neurotoxic effect. Accumulation of unconjugated bilirubin in some brain structures may appear to be a temporary or unexpected impairment in auditory, motor, or cognitive function. The narrowing of the OAE spectrum and low amplitude of the response, the increase in the latent periods of III, IV, V peaks, as well as the prolongation of the time of the central sound conduction of the III-V and I-V waves in all newborns with hyperilirubinemia, indicates a pathology of hearing of central origin with impaired conduction along the auditory pathways at the level the lower and middle thirds of the pons of the brain (Ð ≤ 0.05).
