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.
