BACKGROUND
Permanent congenital hearing loss in children does not only influence speech acquisition but also has a severe impact on the entire intellectual and psychological development, and thus social integration is handicapped. However, at least partial compensation can be achieved by complex rehabilitative measures. One of the first medical therapies in children with congenital hearing loss is to equip them with hearing aids. As part of quality management the purpose of this study is to discuss pedaudiological aspects and results of hearing - impaired children equipped with hearing aids against the background of guidelines from Germany and the US.
METHODS
Data of 107 children equipped with hearing aids from 1997 to 1999 were analysed referring to the relevant German and US guideline.
RESULTS
In 53 girls and 54 boys, 45% were suffering from at least severe, 45% from moderate and 10% from mild hearing loss. 93 children presented sensory hearing loss, 8 combined and 2 conductive hearing loss. 2 children had unilateral hearing loss, one a combined on one ear and a sensory hearing loss on the other and one child had a central auditory processing disorder. The age when the hearing loss was diagnosed depended on its grade and correlated with adverse environmental aspects. 34 children suffered from a syndrome or multiple handicaps, in these cases, the hearing loss was diagnosed at a later date than in children suffering from hearing loss only. In cases with near deafness audiological results with hearing aids were not sufficient; in these cases, cochlea implantation had to be discussed as an alternative measure.
CONCLUSIONS
The data obtained from this study underline the need for universal hearing screening. Discussing the data against the relevant German and US guidelines clearly shows that German benchmarks are not as strict as the American ones. This has to be taken into account for further guideline development in Germany. As permanent hearing loss in children with syndromes and multiple handicaps and children with adverse environment is diagnosed at a later date than in other children public, measures have to be taken to improve this situation.
