ABSTRACT
Hyperbilirubinemia at neonatal period is one of the major deteriorating factors of the auditory system. If left untreated, it may cause certain cerebral damage. This study aims to evaluate the impact of hyperbilirubinemia on the hearing of neonate. This study was conducted on 35 newborn babies with jaundice (bilirubin more than 20 mg/dL). Auditory brainstem response (ABR) and transient evoked otoacoustic emission (TEOAE) tests were performed, after treatment and one year after. ABR test results indicated that 26 children (74.3%) had normal hearing but 9 (25.7%) suffered from an impairment. As for TEOAE test, 30 children (85.7%) passed whereas the remaining (14.3%) seemed to be failures. The comparative results of the two tests pointed to autonomic neuropathy /autonomic dysreflexia symptoms in 5 babies. Due to the high incidence of autonomic neuropathy/autonomic dysreflexia among hyperbilirubinemic babies, screening in this regard seems reasonable. Our result emphasizes the necessity of more experiments on the afflicted areas.
