Salvage of the cochlear implant in cases of skin breakdown over the receiver/stimulator in children.

OBJECTIVE AND METHOD: Skin breakdown over receiver/stimulator (RS) after cochlear implantation poses a serious challenge. We report our experience using a one-stage reconstruction and implant salvage approach.

RESULTS

Between the years 2005 and 2017 five children, all females, with congenital- bilateral sensorineural hearing loss were identified. In all cases, a temporoparietal fascia flap (TPFF) and a large scalp flap were used to provide a two-layer coverage to the exposed RS. In the first three cases, a split-thickness skin graft was used to cover the donor site defect. In the latter two cases, a larger rotation flap was used, and a skin graft was not required. One case required revision due to the dehiscence of the wound and exposure of the RS. In another case, an accidental electrode array explantation occurred and the patient underwent a revision cochlear implantation. All patients had achieved complete healing and no change in hearing thresholds with the implants.

CONCLUSIONS

We demonstrate our one-stage salvage technique with TPFF that saves the implant and prevents a two-stage procedure. The success rate can be improved with special care at reconstruction and with better protection of the implant during the procedure.
