Verz�gerung in der H�rbahnreifung

Abstract

In very young infants, the possibility of a delayed maturation of the auditory pathways must be considered when a hearing loss is diagnosed. Our examples prove that young children with sensorineural hearing loss need more than one objective hearing examination during the first year of life.

Hearing impairment and language delay in infants: Diagnostics and genetics

“…The early estimate of the hearing threshold is therefore to be considered as a working hypothesis that must be reevaluated regularly in the following months by both objective and subjective tests. The progressive nature of hearing impairment, which should also be detected early in order to be able to adjust hearing aids as needed, poses a diagnostic challenge [ 30 ].…”

“…In rare cases, delayed maturity of the auditory pathway in infants, especially after premature births and following hyperbilirubinemia, can lead to immature potential patterns in the BERA. This results in elevated response thresholds associated with actually better inner ear function [ 30 ], [ 44 ].…”

“…after premature birth or hyperbilirubinemia, can also be mistaken for greater hearing loss than is later found. This means that a plausibility check using otoacoustic emissions or subjective audiometry is always necessary [ 30 ], [ 44 ], [ 53 ].…”

Kindliche Hör- und Sprachentwicklungsstörungen, Diagnostik und Genetik

“…Somit ist die frühe Schwellenabschätzung als Arbeitshypothese zu werten, die in den nächsten Monaten regelmäßig sowohl durch objektive wie subjektive Kontrollen zu reevaluieren ist. Eine diagnostische Herausforderung stellen die progredienten Verläufe von Hörstörungen dar, die ebenfalls frühzeitig erkannt werden sollten, um die Hörgeräteanpassung entsprechend verändern zu können[ 30 ] . Monaten und bis zu einem Gehörgangsvolumen von 0,9 ml empfohlen[ 32 -34 ] .…”
