A bacterial or viral inflammation of the eardrum that produces small water or blood blisters on the eardrum and sudden, severe pain in the ear. There may be a yellowish or bloody discharge if the blisters rupture. Bullous myringitis is sometimes mistaken for a ruptured eardrum. Bullous myringitis is generally treated with oral antibiotic medication or ear drops containing one of the corticosteroids and antibiotics. The goal of treatment is to prevent infection of the blisters as they break open. Al¬ though bullous myringitis can be extremely painful, it is not considered serious, and the eardrum usually heals within a week or two with proper treatment.
Myringitis with serous or hemorrhagic blebs or vesicular inflammation of the eardrum and adjacent wall. A sign of infection with Mycoplasma pneumoniae.
