Cholesteatoma. View along the external ear canal showing a large cholesteatoma,a growing collection of skin cells & debris. The dense,granular mass has eroded adjacent tissue & has extended into the posterior part of the middle ear. A large cholesteatoma may press against the eardrum (tympanic membrane),possibly causing it to perforate. Surgery is always necessary to repair an eardrum perforated by a cholesteatoma | |
