To evaluate long-term functional hearing preservation (FHP) in pediatric cochlear implant recipients and identify key predictors, including electrode array length, preoperative thresholds, and presence of inner ear malformations.
Audiologists and cochlear implant surgeons should weigh electrode array length and pre-operative hearing levels carefully when planning pediatric implantation to maximize long-term functional hearing preservation.
Long-term hearing preservation data in pediatric cochlear implant recipients is scarce; identifying modifiable predictors such as electrode array length gives clinicians concrete factors to optimize for better outcomes in children.
- 01Long-term follow-up study assessed functional hearing preservation in pediatric cochlear implant users.
- 02Shorter electrode arrays were associated with better hearing preservation outcomes.
- 03Preoperative residual hearing levels were a key predictor of long-term preservation.
- 04Findings support electric-acoustic stimulation (EAS) candidacy planning in children.
- 05Results highlight the importance of surgical technique and device selection in pediatric implantation.
Electrode array length is a significant predictor of long-term functional hearing preservation in pediatric cochlear implant recipients.
