With expanded candidacy, cochlear implantation candidates increasingly present with residual acoustic hearing. The level and stability of residual hearing is particularly relevant when considering electro-acoustic stimulation (EAS). While adult data suggest relative stability, the natural history of residual hearing in children-who often have distinct and potentially progressive etiologies-remains poorly defined.

Discussion
Signed responses from readers of the wire.
Findings may inform counseling about residual low-frequency hearing preservation in pediatric cochlear implant candidates, but clinical practice changes should await peer review of full results and larger prospective data.
As cochlear implant candidacy criteria expand to include children with more residual hearing, understanding the natural trajectory of that hearing is critical for setting realistic expectations and optimizing device programming strategies.
- 01Study examined residual low-frequency hearing stability in pediatric cochlear implant candidates.
- 02Used contralateral (opposite) ear as a proxy to track natural hearing trajectory over time.
- 03Addresses a gap created by expanded CI candidacy criteria that now include children with acoustic residual hearing.
- 04Findings could inform pre-surgical counseling and post-implant auditory management.
- 05Retrospective design using contralateral ear data limits direct causal inference.
Contralateral ear trajectories can serve as a valid proxy for residual hearing stability in the implanted ear of pediatric cochlear implant candidates.
