The mastoid air cells are thought to protect the delicate structures of the ear, regulate ear pressure and possibly protect the temporal bone during trauma.
When the mastoid cells become infected or inflamed, often as a result of an unresolved middle ear infection (otitis media), mastoiditis can develop.
How is mastoiditis diagnosed?
The most common cause of mastoiditis is an untreated inner ear infection (otitis media). Diagnosis of mastoiditis begins with an examination of the ear. Tests that may be used to confirm a diagnosis include CT scan, MRI, X-ray, blood tests, fluid culture, hearing test, and lumbar puncture or “spinal tap.”
What happens if mastoiditis is left untreated?
If left untreated, mastoiditis can cause serious, even life-threatening, health complications, including hearing loss, blood clot, meningitis, or a brain abscess. But with early and appropriate antibiotic treatment, these complications can usually be avoided and you can recover completely.
