Sažetak
Aim: To present two cases of late complications of cochlear implantation. Case report: In both cases extracochlear extrusion of the implant electrode occurred. More than ten years after successful cochlear implantation, the hearing performance gradually worsened to the point of no intelligibility in both patients. Otomicroscopy revealed chronic otitis media (COM) with an electrode in the external ear canal in implanted ears of both patients. Extracochlear electrode extrusion was noticed on CT scans in both cases. In the first case the device was explanted, the electrode was left in the cochlea and tympanoplasty was performed. Regardless the normal status of the middle ear, extracochlear extrusion occurred again. Conclusion: After extracochlear electrode extrusion, the reimplantation is likely to be unsuccessful.
