Comparison of cortical auditory maturation between children with cochlear implants VS normal hearing children...

Cortical auditory evoked potential (CAEP) is an objective tool for assessing the development of central auditory pathways.

Aimed to assess auditory growth and learning abilities of cochlear-implanted children in mainstream educational settings, comparing with normal-hearing peers. Additionally, the study investigated the association of auditory speech perception with academic performances.

This was a quasi-experimental design post-test with control. Seventy-four children aged 7-12 years old were divided into two groups: CI recipient (n = 37) and normal-hearing (n = 37). P1 wave latency of CAEP was compared between groups. The auditory and speech performances of CI recipients were assessed using CAPS-II and SIRS. Screening Instrument for Targeting Education Risk (SIFTER) and a validated parental questionnaire used to evaluate educational performances. The association between auditory speech perception and academic performances was assessed.

CI children exhibited prolonged P1 wave latency. Despite this difference, the educational performances were comparable to their peers, corresponding to high CAPS II and SIRS scores. Interestingly, no significant association between auditory speech perception and academic performance among CI children.

CAEP is reliable to quantify the development of cortical auditory pathways and should be routinely conducted in the management of CI. Cochlear implantation improves the auditory and academic performances of CI children.
