Zmiany impedancji elektrod u użytkowników implantów ślimakowych

Increasing values of impedance during first fitting of the speech processor support the hypothesis that a layer of fibrous tissue forms around the electrode because of the inflammatory changes or due to exudation of protein. Such changes could be observed after cochlear implantation. Impedance values decrease after first fitting and remain stable. This may suggest that electrical stimulation prevents from adverse changes in the cochlea.
