 A 46-year-old woman,who had undergone canal wall-down tympanoplasty for facial paralysis caused by cholesteatoma,was referred to our hospital because her paralysis had become worsened over the preceeding 2 months. Otomicroscopic findngs and CT images revealed complete disruption of the facial nerve at the mastoid portion and accumulation of debris and crust in the open mastoid. She underwent posterior canal reconstruction tympanoplasty combined with removal of cholesteatoma and the nerve grafting using the great auricular nerve. Facial paralysis due to cholesteatoma is not uncommon,but complete disruption of the facial nerve caused by cholesteatoma has never been reported. In this case,long-term follow-up was necessary to evaluate facial nerve function after nerve grafting.
