Abstract

Acquired external auditory canal (EAC) stenosis is described as resulting from a number of different causes such as infection, trauma, neoplasia, inflammation and radiotherapy. Human papilloma virus (HPV) type 6, a deoxyribonucleic acid (DNA) virus, is considered to cause squamous papilloma of the EAC. In this article, we report a case of a 56-year-old male with warty lesions in the left external ear and a totally stenotic right external ear which had similar lesions one year before the involvement of his left ear. On computed tomography of the temporal bone, there was soft tissue obstruction of the right EAC, and thickening in the skin of the left EAC. The middle ear structures were normal on both sides. Biopsy was performed from the lesion in the left ear, and revealed squamous papilloma. We presented this case because squamous papilloma related bilateral acquired EAC stenosis is a rare entity.
