Foreign body reaction after cochlear implantation.

Cochlear implantation is a widely accepted, safe procedure for patients with severe to profound sensorineuronal hearing loss. While complications are rare, revision surgeries are required for complications like device failure, misplaced electrode, flap necrosis, and wound infection. Foreign body reaction is a rare complication following cochlear implantation. We experienced a case of foreign body reaction after cochlear implantation treated by device removal. Foreign body reaction has to be considered as one of several causes in cochlear implantation cases that show symptoms mimicking recurrent wound infection or delayed extrusion. We report a case of foreign body reaction with a literature review.
