The images were compatible with malpositioning of the electrode array that had apparently violated the scalar wall, entering the petrous apex. Two months later, implant revision surgery was performed. The connecting lead was followed through the mastoid cavity and facial recess. The electrode was then removed, and the cochleostomy was repositioned more anteriorly and inferiorly. The same cochlear implant was then inserted into the cochlea in an attempt to direct the implant past the breach of the basal turn. Intraoperative transorbital plain films verified that the electrode array was correctly placed through the basal turn and was located within the lower two thirds of the cochlear coil. There was no fluid leak detected during the revision procedure.
