Abstract

The results of two-stage audiologic examination (otoacoustic emissions method and assessment of auditory evoked potentials) of 74 term and premature newborns are shown in this article. All patients received treatment for perinatal injuries of central nervous system (cerebral ischemia of various stages of severity). The assessment of brainstem auditory evoked potentials was established to be the most informative diagnostic method both in term and premature infants, moreover the majority of newborns with perinatal brain injuries had increased latencies of brainstem auditory evoked potentials parameters and signs of acoustic analyzer dysfunction, which character depended on the severity of cerebral ischemia.

Summary

Introduction

Нарушения формирования слухового анализатора и слуховые дисфункции — одна из важных причин социальной дезадаптации ребенка и фактор риска инвалидности. Нарушения слуха у новорожденных могут развиваться при поражении слухового анализатора на различных уровнях. В настоящее время рекомендуется оценка короткотремально низкой массой тела, при наличии перинаталь- латентных слуховых вызванных потенциалов у новорожных факторов риска — острых и хронических болезней денных с подозрением на снижение слуха, не прошедших у матери, патологического течения беременности
