Correlative research on the development of expressive vocabulary among children with cochlear implants within two years post-implantation under different compensation modes

To track the growth of expressive vocabulary size in children with cochlear implantation (CI) over the first two years after activation, to compare the differences in expressive vocabulary development among different prosthesis configurations, and to establish milestones for expressive vocabulary development during this period.

Pediatric cochlear implant teams should note that compensation mode (e.g., bimodal fitting, bilateral implants, or implant alone) appears to influence expressive vocabulary growth over two years — though the study's specific findings and sample characteristics need review before changing protocols.

Identifying which hearing compensation modes best support early language development in implanted children has direct implications for pediatric audiological programming and habilitation counseling.

1. 01Longitudinal design tracked expressive vocabulary over 2 years post-cochlear implant activation.
2. 02Different hearing compensation modes (e.g., bimodal, bilateral CI, CI-only) were compared for vocabulary outcomes.
3. 03Expressive vocabulary development trajectories differed across compensation mode groups.
4. 04Findings are relevant to pediatric cochlear implant candidacy counseling and habilitation planning.
