[Cochlear implant operation to summarize and postoperative outcome].

OBJECTIVE

The aim of this study was to evaluate the clinical features of cochlear reimplantation. To review our experience of cochlear reimplant surgery.

METHOD

Retrospective analysis of all 25 cochlear reimplant surgeries between 2002 and 2012. Causes of revision operations, number of electrode channels inserted, surgical findings and postoperative speech performances were analyzed.

RESULT

Causes of reimplantation were eight hard failures; eight poor implanted electrodes position, four poor outcome, three skin flap infection lead to implant device exposure, one postoperative symptoms of facial nerve stimulation, one postoperative temporal bone lesions. All cochlear reimplantations were successfully performed in our hospital, audiologic performances were stable or improved following reimplantation in most of cases.

CONCLUSION

Cochlear implant surgeons should have a good knowledge of how to diagnose cochlear implant failures and how to deal with medical complications related to cochlear implantation. Medical and audiologic outcomes are generally excellent. Cochlear reimplantation appears to be a safe and effective.
