Mastoiditis 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.

Mastoidectomy The mastoid air cells are open spaces containing air that are located throughout the mastoid bone, the prominent bone located behind the ear that projects from the temporal bone of the skull. The air cells are connected to a cavity in the upper part of the bone, which is in turn connected to the middle ear.

- From Wikipedia, the free encyclopedia. Mastoiditis is the result of an infection that extends to the air cells of the skull behind the ear. Specifically, it is an inflammation of the mucosal lining of the mastoid antrum and mastoid air cell system inside the mastoid process.The mastoid process is the portion of the temporal bone of the skull that is behind the ear which contains open, air-containing spaces.ome common symptoms and signs of mastoiditis include pain, tenderness, and swelling in the mastoid region. There may be ear pain (otalgia), and the ear or mastoid region may be red (erythematous). Fever or headaches may also be present.

Mastoidectomy A mastoidectomy is performed to remove diseased mastoid air cells. These cells sit in a hollow space in the skull, behind the ear. The diseased cells are often the result of an ear infection that has spread into the skull.Sometimes the infection spreads onto the temporal bone.If this occurs, parts of the bone may need to be removed. This results in hearing loss. There are several types of mastoidectomy. These include: 1  simple mastoidectomy: the surgeon opens the mastoid bone, removes the infected air cells, and drains the middle ear.f this occurs, parts of the bone may need to be removed.
