Neural response thresholds in the Nucleus Contour cochlear implant before and after stylet removal.

Conclusion: The study shows that there are differences in the measurement of the action potentials with and without the stylet in the Nucleus Freedom Contour Advance that are higher in the apex than in the base of the cochlea.

Objectives: To determine if there are differences in the intraoperative impedances and in the neural response telemetry threshold values in the Nucleus Freedom Contour Advance before and after stylet removal.

Subjects And Methods: This was a prospective clinical study.
