Amplitude growth function of ECochG potentials
No significant differences between groups were detected with slightly better AGF thresholds in the PiP group. AGF-potentials at different frequencies over the follow-up-period are shown in Fig. Results of AGF over a 1-year follow-up period. In the tested frequencies (250, 500 and 1000 Hz), AGF-results of the PiP-group showed a slightly better hearing threshold than the without PiP-group without reaching statistical significance (intraoperative: 250 Hz:
