Your child has mastoiditis. This condition is an infection of the mastoid, the hard, bony area located right behind the ear. The condition is most often the result of an infection that started in the middle ear and spread to the bone.
Mastoiditis is more common in children than adults. Having any of the following may make getting it more likely:
An ear infection
Eustachian tube problems
A problem with the immune system
Abnormal swelling of the tissue inside the skull
Swelling over the mastoid bone causing the ear to turn forward
Redness behind the ear
Drainage from the ear canal or dizziness (uncommon)
Weakened facial muscles (rare)
Your child’s doctor will ask about your child’s medical history. The doctor will also perform a physical exam. This helps find the best treatment. An imaging test, such as CT scan, may be done to help the doctor make a diagnosis. These tests allow the doctor to view the mastoid area.
If mastoiditis is suspected, your child will likely be admitted into the hospital for evaluation and treatment. Your child won’t be sent home until the infection has cleared. The hospital stay can last for 5-7 days or more. In the hospital, your child will be given intravenous (IV) antibiotics for the infection. Your child will see an otolaryngologist, a doctor who specializes in care of the ears, nose, and throat (ENT). The ENT doctor may need to make a tiny incision in the eardrum to allow trapped fluid to drain out (called a myringotomy). This relieves pressure and allows a sample of the fluid to be taken and tested. The test results help the ENT doctor determine which antibiotic to give your child. If these treatments don’t work, surgery may be needed to remove parts of the infected mastoid (called a mastoidectomy).
Once treated, the mastoid often causes no long-term problems. But left untreated, mastoiditis can lead to a serious infection in and around the brain. To protect your child’s health, follow-up with his or her regular doctor or ENT doctor.
