OBJECTIVE AND IMPORTANCE: The goal of this paper is to describe a previously unreported etiology for cochlear implant extrusion. A short literature review is included. This paper represents the first reported case of cochlear implant extrusion secondary to keloid formation. CLINICAL PRESENTATION: We present the case of a 40-year-old male who underwent cochlear implant insertion approximately 5 years prior who later developed a 5 cm post-auricular soft tissue swelling and partial extrusion which interfered with implant function. INTERVENTION: He subsequently underwent wound debridement, cochlear implant removal, and rotational skin flap closure. Final pathology revealed keloid scar. CONCLUSION: Cochlear implant extrusion is a rare complication which has been attributed to various causes. This report identifies keloid formation as another possible source.
