Synopsis

Cholesteatoma of the external ear is a rare inflammatory condition of the external ear canal that is believed to be secondary to canal surgery or trauma but may also be secondary to failure of normal epithelial turnover and shedding of the canal. The condition may be related to prior infection or radiation injury. It is characterized most often by otalgia, ranging from discomfort to dull pain to painful. Other symptoms may include itch, otorrhea, occlusion, conductive hearing loss, or a feeling of fullness. Some cholesteatomas are asymptomatic until discovered upon examination. The condition may be unilateral or bilateral.
