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.

Mastoiditis As mentioned above, mastoiditis most often develops as a result of a middle ear infection. Bacteria from the middle ear can travel into the air cells of the mastoid bone. In addition, a type of skin cyst in the middle ear, called a cholesteatoma, may block drainage of the ear, leading to mastoiditis.

TYMPANOMASTOIDECTOMY Depending on the specific condition in patient’s ear, an operation on the mastoid bone to control infection may be done, together with a procedure to restore hearing. This procedure is called a tympanomastoidectomy. The mastoid is a honeycomb cavity in the temporal bone, which lies directly behind the ear and is connected to the middle ear space. When a hole arises in the eardrum due to previous injury or infection, or when a long-standing infection persists with tissue in the middle ear or mastoid, mastoid surgery often becomes necessary to alleviate this infection. This part of the procedure is called mastoidectomy. The procedure used to restore or retain hearing is called a tympanoplasty. “Tympanum” refers to the middle ear cavity; “plasty” means “repair of”; thus “tympanoplasty.”

The mastoid notch is located medial to the mastoid process.

- By its liability to septic infection and its proximity to the brain and other important structures the portion of the temporal bone.known as the mastoid process is of great importance.Infection spreads to cavities in the bone from the middle ear, and is always to be apprehended when this organ is infected.he tympanic antrum, a cavity in the mastoid bone, lies behind the middle ear, with which it is connected by an opening, the aditus-ad-antrum, within the floor of which is the facial nerve. Internal to the antrum, merely seperated by a plate of bone, are the lateral or transverse sinus and the brain.

Removal of Cholesteatoma via Modified Radical Mastoidectomy Removal of Cholesteatoma via Modified Radical Mastoidectomy. Modified radical mastoidectomy, also known as canal wall down (CWD) mastoidectomy, is a surgical procedure which involves removal of the posterior (back) wall of the ear canal to create a common cavity for the mastoid and ear canal. This single cavity also known as mastoid bowl opens up to the outside of the ear canal.
