Abstract

Osteoma is a benign neoplasm that can occur and extend beyond the nearest region in the external auditory canal (EAC); however, a multiple growth of the tumor in the ipsilateral ear has never been reported. A 41-year-old male patient having a past history of uncertain chronic otitis media complained of recent otalgia and progressive hearing loss in the same ear. Physical examination showed that two hard masses arising from both anterior and posterior aspect of the right EAC were contacting each other and obstructing most of the lumen. High resolution computed tomography scan revealed not only two growing exophytic bone lesions causing EAC stenosis but also inflammation of the middle ear and sclerotic mastoid cavity. We performed excision and middle ear surgery at the same time. Both specimens were pathologically confirmed as osteomas, so we report this unusual case with a review of literature.
