Overview

Inverted papilloma is a very rare finding in the middle ear. It is a benign, though locally aggressive tumour with a tendency towards malignant transformation. The diagnosis is usually established postoperatively, based on the histological examination, because the local finding is not specific and resembles chronically inflamed tissue in chronic otitis media. Surgery is the treatment of choice. Radiotherapy is reserved for inoperable tumours or a recurrent disease. In this case report, we present a case of a 62-year-old man, who underwent canal wall down tympanoplasty for chronic otitis media in a district hospital many years ago. A few years ago he was examined for pulsatile tinnitus and hearing impairment at our clinic. A combined-approach tympanoplasty did not reveal the expected tumour (only stiff scars) and a clearance of the middle ear cavity was performed. Histological examination revealed an inverted papilloma. A CT scan performed postoperatively proved a tumour persistence. Therefore, a radical mastoidectomy was indicated. The patient is disease-free with no signs of recurrence during 32-month follow-up.
