Mastoiditis is an infection of the mastoid bone of the skull. The mastoid is located just behind the ear.

Causes

Mastoiditis is usually caused by a middle ear infection (acute otitis media). The infection may spread from the ear to the mastoid bone of the skull. The mastoid bone fills with infected materials and its honeycomb-like structure may deteriorate.

Mastoiditis usually affects children. Before antibiotics, mastoiditis was one of the leading causes of death in children. Now it is a relatively uncommon and much less dangerous condition.

Mastoiditis is an infection of the bony air cells in the mastoid bone, located just behind the ear. It is rarely seen today because of the use of antibiotics to treat ear infections. This child has drainage from the ear and redness (erythema) behind the ear over the mastoid bone.

Symptoms

  • Drainage from the ear
  • Ear pain or discomfort
  • Fever, may be high or suddenly increase
  • Headache
  • Hearing loss
  • Redness of the ear or behind the ear
  • Swelling behind ear, may cause ear to stick out
  • Exams and Tests

An examination of the head may reveal signs of mastoiditis. The following tests may show an abnormality of the mastoid bone:

  • CTscan of the ear
  • Head CT scan

A culture of drainage from the ear may show bacteria.

Treatment

Mastoiditis may be difficult to treat because medications may not reach deep enough into the mastoid bone. It may require repeated or long-term treatment. The infection is treated with antibiotics by injection, then antibiotics by mouth.

Surgery to remove part of the bone and drain the mastoid (mastoidectomy) may be needed if antibiotic therapy is not successful. Surgery to drain the middle ear through the eardrum (myringotomy) may be needed to treat the middle ear infection.

Outlook (Prognosis)

Mastoiditis is curable with treatment. However, it may be hard to treat and may come back.

Possible Complications

  • Destruction of the mastoid bone
  • Dizziness or vertigo
  • Epidural abscess
  • Facial paralysis
  • Meningitis
  • Partial or complete hearing loss
  • Spread of infection to the brain or throughout the body
  • When to Contact a Medical Professional

Call your health care provider if you have symptoms of mastoiditis.

Call for an appointment with your health care provider if:

  • You have an ear infection that does not respond to treatment or is followed by new symptoms
  • Your symptoms do not respond to treatment

Prevention

Promptly and completely treating ear infections reduces the risk of mastoiditis.

Benign positional vertigo is the most common type of vertigo. Vertigo is the feeling that you are spinning or that everything is spinning around you. It may occur when you move your head in a certain position.

The inner ear has fluid-filled tubes called semicircular canals. When you move, the fluid moves inside these tubes. The canals are very sensitive to any movement of the fluid. The sensation of the fluid moving in the tube tells your brain the position of your body. This helps you keep your balance.

BPPV occurs when a small piece of bone-like calcium breaks free and floats inside the tube. This sends confusing messages to your brain about your body's position.

BPPV has no major risk factors. However, your risk for developing BPPV may increase if you have:

  • Family members with BPPV
  • Had a prior head injury (even a slight bump to the head)
  • Had an inner ear infection called labyrinthitis

Causes

Benign positional vertigo is also called benign paroxysmal positional vertigo (BPPV). It is caused by a problem in the inner ear.

The inner ear has fluid-filled tubes called semicircular canals. When you move, the fluid moves inside these tubes. The canals are very sensitive to any movement of the fluid. The sensation of the fluid moving in the tube tells your brain the position of your body. This helps you keep your balance.

BPPV occurs when a small piece of bone-like calcium breaks free and floats inside the tube. This sends confusing messages to your brain about your body's position.

BPPV has no major risk factors. However, your risk for developing BPPV may increase if you have:

  • Family members with BPPV

  • Had a prior head injury (even a slight bump to the head)

  • Had an inner ear infection called labyrinthitis

Symptoms

BPPV symptoms include:

  • Feeling like you are spinning or moving

  • Feeling like the world is spinning around you

  • Loss of balance

  • Nausea and vomiting

  • Hearing loss

  • Vision problems, such as a feeling that things are jumping or moving

The spinning sensation:

  • Is usually triggered by moving your head

  • Often starts suddenly

  • Lasts a few seconds to minutes

Certain positions can trigger the spinning feeling:

  • Rolling over in bed

  • Tilting your head up to look at something

Exams and Tests

To diagnose BPPV, your health care provider may perform a test called the Dix-Hallpike maneuver.

  • Your provider holds your head in a certain position. Then you are asked to lie quickly backward over a table.

  • As you do this, your provider will look for abnormal eye movements and ask if you feel like you are spinning.

If the Dix-Hallpike test doesn't show a clear result, you may be asked to do other tests.

Your provider will do a physical exam and ask about your medical history. You may have brain and nervous system (neurological) tests to rule out other causes. These may include:

  • EEG

  • Electronystagmography (ENG)

  • Head CT

  • Head MRI

  • Hearing test

  • Magnetic resonance angiography of the head

  • Warming and cooling the inner ear with water or air to test eye movements. This is called caloric stimulation.

Treatment

Your provider will do a procedure called Epley's maneuver. It can move the small piece of calcium that is floating inside your inner ear. This treatment works best to cure BPPV. Other exercises don't work as well.

Some medicines can help relieve spinning sensations.

  • Antihistamines

  • Anticholinergics

  • Sedative-hypnotics

However, these medicines often do not work well for treating vertigo.

To keep your symptoms from getting worse, avoid the positions that trigger it.

Outlook (Prognosis)

BPPV is uncomfortable, but it can usually be treated with Epley's maneuver. It may come back again without warning.

Possible Complications

People with severe vertigo may get dehydrated due to frequent vomiting.

When to Contact a Medical Professional

Call your health care provider if:

  • You develop vertigo

  • Treatment for vertigo doesn't work

Get immediate medical help if you also have symptoms such as:

  • Weakness

  • Slurred speech

  • Vision problems

These may be signs of a more serious condition.

Prevention

Avoid head positions that trigger positional vertigo.

Alternative Names

Vertigo - positional; Benign paroxysmal positional vertigo; BPPV: dizziness- positional
