What is it?

Mastoiditis is the result of an infection that extends to the air cells of the mastoid bone – a part of the skull behind the ear. Mastoiditis is usually caused by untreated acute otitis media (middle ear infection). The condition is most common in children.
Without treatment mastoiditis may have serious complications, all connected to the infection spreading to surrounding structures. Complications include meningitis, epidural abscess, hearing loss, vertigo, facial paralysis and more.
