Late skin flap failure following cochlear implantation.

The objective of the study was to determine risk factors for late skin flap failure following cochlear implantation. The study design was a retrospective case series. Data were collated from 371 implanted patients over a ten-year period. Of these patients, 1.3 per cent (n = 5) developed late skin flap failure. It is concluded that skin flap failure is a significant, though relatively uncommon, complication of cochlear implant surgery. What causes flap failure and why it should occur in such a variable fashion are still largely unknown, though infection undoubtedly plays an important role. The aetiological factors associated with flap failure and possible prevention strategies are discussed. Copyright (c) 2008 John Wiley & Sons, Ltd.
