Mastoiditis

Medically reviewed by Drugs.com. Last updated on Apr 2, 2024.

Mastoiditis is an infection in the mastoid bone of your skull. The mastoid bone is located behind your ear. Mastoiditis is often caused by an ear infection that spreads. Your ear canal swells and traps fluid inside your ear. Trapped fluid causes bacteria to grow and spread to your mastoid bone. Have someone stay with you to watch for complications of mastoiditis such as brain swelling. They may need to call 911 when you are unable to do so.
