A cholesteatoma is a growth (cyst) inside the ear. The most common cause is a problem with the eustachian tube. After the growth starts, it can keep growing and cause ear infections. Your child may feel pain and pressure in or near one or both ears. Your child also may have bad-smelling fluid that drains from the ear. Your child may lose hearing in that ear. Hearing may come back after the growth is removed.

Your child's doctor may do tests to find out the size and shape of the growth. The doctor may clean your child's ear and prescribe antibiotics if there is an infection. In most cases, children have surgery to remove the growth. After surgery, your child will need follow-up care to be sure the growth and infections don't come back.

• If the doctor prescribed antibiotics for your child, give them as directed. Don't stop using them just because your child feels better. Your child needs to take the full course of antibiotics.
• Give your child acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) for pain. Read and follow all instructions on the label. Don't give aspirin to children and teens. It has been linked to Reye syndrome, a rare but serious illness.
• Don't give your child two or more pain medicines at the same time unless the doctor told you to. Many pain medicines have acetaminophen, which is Tylenol. Too much acetaminophen (Tylenol) can be harmful.
• Apply heat to the ear to ease pain. Use a warm washcloth. Be careful not to burn the skin around the ear. Your child's ear may have some drainage.
• If you are going to have the growth removed, your doctor will give you instructions for your child's care before and after surgery.
• Do not put anything into your child's ear canal. For example, do not use a cotton swab to clean the inside of your child's ear. It can damage the inner ear. If you think that your child has something inside the ear, ask your doctor to check it.
