Summary

Cochlear implant device failures occurred in 4.0% of paediatric cases. As implant programs expand, managing device explantation and reimplantation becomes crucial for resource allocation.

Background:

Cochlear implantation is a vital auditory rehabilitation tool for children.
Long-term device durability is essential for successful outcomes.
Understanding pediatric cochlear implant failure rates informs clinical practice.

Purpose of the Study:

To assess the durability and failure rates of cochlear implant devices in a large pediatric population.
To analyze factors influencing device failure and reimplantation needs.

Main Methods:

A retrospective database review of 363 children who received cochlear implants between 1989 and March 2002.
Analysis of device explantation cases due to device failure, with or without subsequent reimplantation.

Systematic Hearing Performance Evaluation Process for Adolescents with Cochlear Implantation at Early Ages

Systematic Hearing Performance Evaluation Process for Adolescents with Cochlear Implantation at Early Ages

Published on: March 24, 2023

Main Results:

Fifteen device failures were identified in the cohort.
The overall device failure rate was 4.0% per implanted device.
The cumulative failure rate based on user experience was 0.8%.

Conclusions:

Pediatric cochlear implant device failure necessitates explantation and reimplantation.
Growing cochlear implant programs will increase the demand for these procedures.
Effective resource allocation and program development are critical to address future needs.
