Abstract
• A case of cholesteatoma induced by stapedectomy is reported. A year after a successful stapedectomy, the wire prosthesis extruded in part through the eardrum. Exploration revealed a cholesteatoma around the prosthesis down to the oval window. The cholesteatoma was removed and the prosthesis replaced. The patient returned for further exploratory surgery 15 months later when the prosthesis extruded again, this time due to necrosis of the distal part of the long process of the incus. There was no return of cholesteatoma. A new prosthesis was crimped on the incudal stump and covered with tragal cartilage and perichondrium. A two-year follow-up was uneventful.
