Conclusion: according to the received information, the active electrode migrated partially out of cochlea post-operatively, as confirmed by diagnostic imaging, and a revision surgery was required to reinsert the active electrode array.The device investigation shows damages to the active electrode lead by a sharp instrument and to the electrode contacts, which are typical for occurring during surgical intervention and reinsertion attempts.Reportedly, the damage inadvertently occured during the revision surgery.In addition, a full insertion could not be achieved during initial implantation surgery.The investigation results appear to match the problems mentioned in the recipient report.This is a final report.
