where is the mastoid bone?
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. The mastoid cells help maintain the air space in the middle ear. Mastoiditis can develop if the mastoid cells become infected or inflamed, often as a result of a persistent middle ear infection (otitis media). This can cause the porous bone to break down.
