Mastoiditis is an inflammation or infection of the mastoid bone, which is located behind the ear. The mastoid bone is a hollow, air-filled space within the temporal bone of the skull. This condition often develops as a complication of untreated or inadequately treated acute otitis media, a middle ear infection. Bacteria that cause the middle ear infection can spread to the mastoid air cells.

Symptoms of mastoiditis can include ear pain, fever, swelling and redness behind the ear, and a discharge from the ear. The skin over the mastoid bone may become tender to the touch, and the earlobe might protrude outwards. In some cases, hearing loss can occur.

Diagnosis typically involves a physical examination, assessment of medical history, and imaging studies such as X-rays, CT scans, or MRI scans. Laboratory tests like blood work may also be performed to identify the specific type of bacteria causing the infection.

Treatment usually consists of antibiotics, often administered intravenously, to combat the infection. In some instances, surgical intervention may be necessary to drain the infected pus from the mastoid bone, a procedure known as a mastoidectomy. Prompt medical attention is crucial to prevent serious complications, which can include hearing loss, damage to facial nerves, or the spread of infection to the brain.
