Infection of the Mastoidectomy Cavity

A mastoidectomy is a surgical procedure to remove the mastoid bone, an area of the skull, which is located directly behind the ear. Mastoidectomy is done to treat recurring or chronic middle ear infections. After the mastoidectomy is complete, the mastoid cavity, the space left behind, must be kept clean and infection-free.

Symptoms of Infection

Signs that the mastoid cavity may have become infected include increased swelling, drainage of fluid or pus, or pain behind the ear. A fever may develop as well. Many times a mild infection can be treated with antibiotics and keeping the mastoidectomy cavity clean; however, if the infection persists or worsens, an additional procedure may be required to remove more bone or tissue in the area.

Preventing Infection

There are several methods to prevent infection of the mastoidectomy cavity:

Maintain a high level of hygiene in the area behind the ear, avoiding the use of cotton swabs.
Keep the area clean and dry using gentle soap.
Avoid swimming and water sports, or wear waterproof protection when in and near the water.
Take preventive antibiotics before any surgery affecting the sinuses or ears.
Always use a clean towel or facecloth when drying the area.
Make sure that the surgical incision is clean and dry.
Avoid activities that create excessive perspiration in the area.
If prescribed, use a topical antiseptic or antibiotic.

If the mastoidectomy cavity becomes infected, it's important to seek medical attention right away. Treating the infection promptly can help prevent further complications.
