Intraoperative Impedance Gradient as a Physiological Indicator of Electrode-Neural Interface in Pediatric Cochlear Implantation

Key Points

Higher intraoperative impedance values are observed in apical electrodes, indicating anatomical variations.
Monitoring impedance offers insights into neural interface integrity and can guide electrode positioning.
Assessment using impedance gradients during pediatric cochlear implantation can enhance surgical outcomes.
This approach may enable more precise electrode placements, improving hearing prospects for children.

Abstract

Intraoperative impedance monitoring reveals a strong and physiologically consistent gradient, with higher values in apical electrodes. This gradient reflects anatomical and tissue interface variations, which may offer a valuable physiological indicator for intraoperative electrode positioning and neural interface integrity.
