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.
报告了1例镫骨切除术后胆脂瘤病例。镫骨切除术成功1年后，钢丝假体部分穿出鼓膜。探查发现假体周围直至卵圆窗有胆脂瘤。切除胆脂瘤并更换假体。15个月后患者因假体再次穿出而再次接受探查手术，此次是由于砧骨长突远端坏死。胆脂瘤未复发。在砧骨残端压接一个新的假体，并用耳屏软骨和软骨膜覆盖。两年随访无异常。
