[Monitoring of implant electrode impedance].

Monitoring of implant reference and active electrode impedance was carried out intraoperatively, at the first fitting, during the first two weeks after the first fitting, and within the next 6 months. It was shown that impedance of the electrodes during surgery was significantly lower than after the first fitting. Moreover, the intraoperative impedance of all active electrodes was significantly lower than in the postoperative period. Overall, the impedance tended to decrease from the first day of fitting to the 10th day after it. It became stabilized within 6 months after the first fitting when impedance of the reference electrode significantly increased. A putative explanation of the results of the monitoring is proposed.
