Conclusion: damage to the active electrode which is consistent with minute device mobility was determined to have led to device failure over time due to fatigue wire breakages.Further the most basal channel was left outside of cochlea at implantation surgery.The problems given in the recipient report appear to match the damage found.This is a final report.
