title: Cochlear implant extrusion secondary to keloid formation.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  METHODS
  He subsequently underwent wound debridement, cochlear implant removal, and rotational skin flap closure. Final pathology revealed keloid scar.
  
  
  CONCLUSIONS
  Cochlear implant extrusion is a rare complication which has been attributed to various causes. This report identifies keloid formation as another possible source.
