특발성 외이도 진주종 3례

Abstract

Many etiologic factors have been attributed to the development of cholesteatoma in the external ear canal. External auditory canal cholesteatoma which does not have any etiologic factor is a very rare disease in the otologic field. We report 3 cases of external auditory canal cholesteatoma without contributing causes, which could be diagnosed by physical findings, radiologic evaluation and confirmation of pathology with surgery.
