title: [A case of middle ear adenoma].
abstract: Middle ear adenomas are rare and difficult to diagnose. Recent histological studies suggest the presence of a distinct disease entity known as a middle ear adenoma. A 16-year-old boy with a middle ear tumor was treated by partial temporal bone resection, and the tumor was removed by a combined method using the middle cranial fossa and infratemporal fossa approaches. Histological and immunohistochemical studies on this tumor showed the findings of a benign adenoma. Left facial palsy was noted postoperatively, but it subsequently recovered almost completely.
