Mastoiditis is a serious bacterial infection that affects the mastoid bone behind the ear. It's usually more common in children, although adults can also sometimes be affected. The mastoid bone has a honeycomb-like structure that contains air spaces called mastoid cells.
Mastoiditis occurs when ear infections cause infection in the mastoid bone. The mastoid bone can be found directly behind the ear. Mastoiditis causes the area behind the ear to swell and protrude out of the skin. The bump behind ear is accompanied with fever, ear pain, hearing loss and ear redness.
