Perforated eardrum. View along the external ear canal showing a large perforation of the eardrum, the tympanic membrane. A cholesteatoma, a cream- white mass of cellular debris & cholesterol, is visible through the near circular hole in the eardrum. In foreground is a large bulge in the root of the ear canal. Deafness of varying degrees accompanies a perforated eardrum. Surgery is always required to repair a perforated eardrum caused by pressure from a cholesteatoma.
