title: [The examinations of hearing in infants treated in neonatal intensive care units].
abstract: The aim of the study was the estimation of hearing and the analysis of the risk factors for hearing loss in infants treated in neonatal intensive care units. The examinations were performed in 287 infants, who we examined in ENT Department between the ages of three and six months after discharge from neonatal intensive care unit. The infants were investigated with the use of ABR elicited with clicks and tone burst of 500 and 1000 Hz. Elevated auditory thresholds were found in 48 neonates in the first examination and in 27 in the second examination. Among the risk factors we observed the most frequently: gestational age < 33 Hbd, birth weight < 1500 g, respiratory and cardiovascular disorders and intracranial haemorrhages.
