Case report: explantation of a cochlear implant secondary to chronic granulating labyrinthitis

In the published series of our first 100 cochlear implants only three developed major complications (Proops et al., 1999). We present a rare case of late granulations forming around a Nucleus cochlear implant, giving rise to erosion of the entire cochlea and adjacent mesotympanum. This pathology has only been reported once in the literature (Bertuleit et al., 1999).
