What is the difference between otitis externa and otitis media?

Otitis means inflammation of the ear. The inflammation is usually due to an infection. Otitis externa means that the inflammation is confined to the external part of the ear canal and does not go further than the eardrum. See separate leaflet called Ear Infection (Otitis Media), for an infection of the middle ear.

How do you differentiate between acute and otitis media?

The position of the tympanic membrane is a key for differentiating acute otitis media and otitis media with effusion. In acute otitis media, the tympanic membrane is usually bulging. In otitis media with effusion, it is typically retracted or in the neutral position.
