Case description

Bullous myringitis is an infection of the outer epithelial layer of the tympanic membrane and of the deep pony external auditory canal, in which small, fluid-filled blisters form on the eardrum and sometimes the adjacent deep canal. These blisters usually cause severe pain. Bullous myringitis is thought to be caused predominantly by viruses, although Streptococcus pneumoniae is the most commonly identified bacteria. Other bacterial pathogens may include Haemophilus influenzae, Moraxella catarrhalis, Group A Streptococcus, Staphylococcus aureus. Note the large fluid-filled blister in the deep canal arising from the tympanic membrane.
