Cochlear Implant Failure, Revision, and Reimplantation

Abstract

All reimplanted patients with available data had good audiometric outcomes, with the exception of those reimplanted for soft failure who had poor immediate auditory function. Using the manufacturers' recommended surgical technique, including drilling a bony recess with suture fixation, very low surgical revision rates were achieved. Pediatric patients experienced significantly higher complications requiring CIR. All hard failures in this series occurred in the pediatric group and in a single device. Continued follow-up will be needed to determine if additional devices will succumb to this mode of failure.
