What are the white plaques on the tympanic membrane?
Healthy tympanic membranes are usually pearly gray. Diseased tympanic membranes may be dull and become red or yellow. Is the eardrum injected? Injection refers to the dilatation of blood vessels, making them more apparent. The blood vessels should be visible only around the perimeter of the membrane. Dense, white plaques on the tympanic membrane may be caused by tympanosclerosis, which is caused by deposition of hyaline material and calcification within the layers of the tympanic membrane. This condition is commonly (in 50% to 60% of cases) secondary to the insertion of ventilation tubes. The classic horseshoe shape of tympanoscle-rosis is seen in the tympanic membrane shown in Figure 11-18. Despite the size of these lesions, they usually do not impair hearing and are rarely of clinical importance. If the lesion extends into the middle ear, however, conductive deafnessmay result.
