Cochlear implant extrusion secondary to keloid formation
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.
