Otitis media. View along the external ear canal in chronic secretory otitis media, a peristent infection of the middle ear. The eardrum (tympanic membrane, the central bulge) appears dull and retracted with a few radial blood vessels on its surface. Otitis media occurs most often in children, with symptoms of earache & sometimes a bloody discharge. A build-up of pus may cause the eardrum to bulge & eventually perforate, resulting in slight deafness. The first line of treatment is with pain-killing drugs & antibiotics. Chronic pesistent cases may need a myringotomy, an operation to drain off the pus.
