Electrode Impedance Fluctuations and Sudden Decline in Cochlear-Implant Benefit

Conclusions Overall, we found no similarities between cases that could potentially explain the sudden electrode impedance value increase or the decrease in speech perception scores. Each case should be evaluated uniquely and carefully for CI revision operations by frequent monitoring, including mapping and speech perception testing. The most common factor contributing to each teen's eventual resolution of electrode impedance values and speech perception scores was time.
