Can we trust our audiological CI screening in young children?
Introduction
During the preliminary examination, the audiological indication for CI fitting is made in young children by means of recording acoustic evoked potentials (ABR, SN10, etc.). In order to measure the acoustic hearing subsequently, subjective audiograms are currently measured in children who have received a CI and compared with the objective preoperative results.
Material and Methods
Children whose surditas were diagnosed in infancy using objective measurement methods and fitted with CI and are currently of audiometry age (>3 years) will receive subjective audiometry of their residual hearing.
Results
To date, audiometric data of residual hearing are available for 82 children aged 3-10 years. In 16 children there is no bilateral residual hearing over the frequencies 125 Hz – 4 kHz. The remaining 66 children show unilateral or bilateral residual hearing in different frequencies.
Conclusions
The residual hearing of children should be subjectively assessed as early as possible after CI fitting in order to be able to use low-frequency residual hearing for electro-acoustic stimulation if necessary and to enable the child to mature auditory-central in these frequency ranges as well. Further research is needed to optimize objective measurement methods and also to reliably detect the low-frequency range in young children.
