Mastoiditis in Children: Care Instructions

Skip Navigation

Overview

Mastoiditis (say "mass-toy-DY-tus) is an infection that affects the bone behind the ear. It can occur after your child has an ear infection. Sometimes an ear infection can spread to areas outside of the ear. This can cause new problems, like mastoiditis.

The swelling behind your child's ear can push the ear forward. As the swelling goes away, the ear will move back to its normal place.

Antibiotics are the most common treatment for mastoiditis. If the antibiotics don't work, your child may need ear tubes put in their ears to help drain fluid over time.

Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and contact your doctor if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.

How can you care for your child at home?

  • Be safe with medicines. Read and follow all instructions on the label.
    • If your child is not taking a prescription pain medicine, ask the doctor if your child can take an over-the-counter pain reliever.
    • If the doctor gave your child a prescription medicine for pain, give it as prescribed.
    • Don't give aspirin to children and teens. It has been linked to Reye syndrome, a rare but serious illness.
    • Store your child’s prescription pain medicines where no one else can get to them. When you're done using them, dispose of them quickly and safely.
  • Be careful if you are giving your child over-the-counter cold or flu medicines and Tylenol at the same time. Many of these medicines have acetaminophen, which is Tylenol. Read the labels to make sure that you are not giving your child more than the recommended dose. Too much acetaminophen (Tylenol) can be harmful.
  • Give your child antibiotics as directed. Don't stop using them just because your child feels better. Your child needs to take the full course of antibiotics.
  • Place a warm, moist washcloth on your child's ear to help relieve pain.
  • Ask your doctor if your child needs to keep water from getting in the ears when bathing or swimming.

    • Pus draining from the area.
    • A fever.
