Overview

Mastoiditis is an inflammation or infection of the mastoid bone. This bone is one of the bones in the head. It is located behind the ear. The mastoid bone is made of cells that drain the middle ear. Mastoiditis may be mild or very serious.

Causes

Mastoiditis is a complication of a middle ear infection. It happens when the infection in the middle ear spreads into the mastoid bone.

Symptoms

Here are the most common symptoms of mastoiditis:

  • Pain, redness, or swelling behind the ear
  • Ear pain
  • An ear lobe that sticks out because of swelling of the mastoid bone
  • Fever
  • Irritability or fussiness
  • Headache
  • Hearing loss

The symptoms of mastoiditis may look like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.

Diagnosis

Your child’s healthcare provider will ask questions about your child’s health history and current symptoms. He or she will examine your child. The provider will pay close attention to the ears, nose, and throat. He or she will use a lighted instrument called an otoscope to look at the middle ear. Your child may need an X-ray and CT scans of the mastoid area. Fluid from the middle ear may be sent to the lab to be checked.

Treatment

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.

Treatment usually includes antibiotic medicine and draining the middle ear. Your child may need ear tubes. Your child may need to stay in the hospital. Some children may need other surgery.

Complications

Possible complications include:

  • Hearing loss
  • Serious infection in nearby tissue
  • Facial nerve damage
  • Inner ear problems
  • Inflammation or infection of the covering of the brain and spinal cord (meningitis)

Mastoiditis is usually treated by an ear, nose, and throat (ENT) healthcare provider. It is very important for your child to go to all follow-up appointments to check for hearing problems and other complications.
