Overview

Retrospective study observes fluctuating electrode impedance across five years in deaf children, highlighting the need for routine monitoring during early electrical stimulation.

Key Points

  • Electrode impedance fluctuates significantly in basal cochlear implant channels during early use, followed by stabilization across apical and medial contacts over five years.
  • A critical impedance exceeding 15 kilohm occurred in 13.8 % of patients, requiring speech processor reprogramming or contact disconnection to preserve device function.
  • Retrospective study of 58 pediatric cochlear implant recipients highlights the necessity of monitoring electrical stimulation to ensure optimal sound perception in children.
