Detecting and managing partial shorts in Cochlear implants: A validation of scalp surface potential testing.

ABSTRACT:

Objective

To investigate the value of scalp surface potentials to identify and manage partial short circuits to ground in cochlear implant electrodes.

Design

A retrospective review of patients with suspected partial short circuits.

Main outcome measure

Electrical output of individual electrodes was measured using scalp surface potentials for patients reporting a change in hearing function. Electrical output was compared to functional performance and impedance measurements to determine if devices with suspected partial short circuits were experiencing a decrease in performance as a result of reduced electrical output. Electrical output was checked in an artificial cochlea for two implants following explant surgery to confirm scalp surface potential results.
