Malignant Otitis Externa - Necrotizing External Otitis


Symptoms & Signs

What are the signs and symptoms of the infection?

The first signs of infection are:

  • pain in the opening to the ear canal and ear flap
  • drainage of pus from the ear canal
  • low-grade fever
  • As the infection spreads into the bone, symptoms can include:

  • severe pain
  • thickening and swelling of the skin covering the temporal bone
  • high fever
  • a lot of swelling and infected material in the external canal
  • swelling of the skin around the ear
  • If the infection affects the nerves that control movement in the face, facial paralysis or weakness may occur. Should the infection spread to the inner ear, hearing loss and dizziness may result. The infection can even spread to the brain, which may lead to meningitis. This is an infection of the membrane covering the brain and spinal cord. The brain material itself may also become infected.
