From: Effect of initial switch-on within 24 hours of cochlear implantation using slim modiolar electrodes

Correlation between device usage time and impedance change between the first and second mapping in the early switch-on group. The cochlear implant usage time does not correlate with changes in the measured impedance on the apical electrodes (a) as well as on the mid-portion (b) and basal electrodes (c).
