Long-Term Preservation of High-Frequency Hearing After Cochlear Implantation in a Child with Substantial Residual Hearing: A Case Report

/Objectives : Cochlear implantation (CI) in children with substantial residual hearing remains challenging because of the risk of hearing loss. Partial deafness treatment and hearing preservation have traditionally focused on functionally useful low-frequency hearing, while residual hearing in the high-frequency range has not been specifically addressed in established classifications....

This single case supports the feasibility of long-term high-frequency hearing preservation with partial deafness treatment protocols in paediatric cochlear implantation, but evidence is insufficient to change practice; larger controlled studies are needed.

Long-term acoustic hearing preservation after paediatric cochlear implantation remains a key clinical goal, and this case contributes to the sparse evidence base for partial deafness treatment in children with substantial residual hearing.

1. 01Single paediatric case demonstrating long-term high-frequency hearing preservation post-cochlear implantation.
2. 02Partial deafness treatment (PDT) protocol used — designed to combine electric and acoustic stimulation.
3. 03Child had substantial residual hearing prior to implantation, a less common candidacy profile.
4. 04Long-term follow-up duration not specified in available abstract but described as sustained preservation.
5. 05Case report level evidence; findings cannot be generalised without larger cohort studies.
