Auditory and Language Development in Children with White Matter Diffused Lesions Using Cochlear Implants.

BACKGROUND

The objective was to study the auditory and speech and language development in children with white matter diffused lesions using cochlear implants (CIs). A total of 12 pediatric CI recipients with diffused white matter lesions (WMLs) were compared with 12 implant age-matched children without WMLs.

METHODS

The measures included for comparison of performance were sound field aided thresholds, speech identification, and language development at 2 years post cochlear implantation.

RESULTS

Analysis revealed auditory detection was within the soft conversational level and no statistically significant difference was noticed in speech perception scores between the 2 groups. However, children with WMLs demonstrated significantly lower receptive and expressive language ages compared to the control group.

CONCLUSION

Despite preserved auditory detection, white matter diffuse lesions appear to significantly impact language comprehension and expression. This may result from lesions interfering with cognitive processes crucial for speech and language development. The finding highlights the need for comprehensive pre-implant evaluations, counseling on guarded prognosis and tailored rehabilitation strategies for children with white matter diffuse lesions.
