Peritonsillar Abscess

WHAT YOU NEED TO KNOW:

What is a peritonsillar abscess?

A peritonsillar abscess, or PTA, is a collection of pus in the peritonsillar space. The peritonsillar space is the area between your tonsil and the back wall of your throat. It is near the opening of the tubes leading to your stomach and lungs.

What causes a peritonsillar abscess?

A PTA is caused by bacteria. It often results from an infection of your tonsils that spreads to the tissues around it. PTA may happen after a mouth infection, including an infection of the teeth and salivary glands. The salivary glands are the organs in the mouth that make saliva.

What are the signs and symptoms of a peritonsillar abscess?

  • Sore throat, often severe

  • Drooling or bad breath

  • Voice change

  • Fever

  • Loss of appetite

  • Red and swollen tonsil or throat

  • Ear pain

  • Pain or difficulty when you open or close your mouth, swallow, and move your neck

How is a peritonsillar abscess diagnosed?

Your healthcare provider will examine your mouth and throat. He will look to see how red or swollen your abscess is or check to see if it is draining. You may need any of the following:

  • Blood tests may show infection or to give information about your overall health.

  • Needle aspiration may show what is causing your abscess. A needle will be used to take the fluid out of the abscess. The fluid is sent to a lab for tests.

  • A CT scan or ultrasound may show the peritonsillar abscess. You may be given contrast liquid to help the abscess show up better in the pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid.

How is a peritonsillar abscess treated?

Treatment is done to cure your PTA and prevent more serious problems.

  • Antibiotics help treat or prevent a bacterial infection.

  • Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Acetaminophen can cause liver damage if not taken correctly.

  • NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask if NSAIDs are safe for you. Always read the medicine label and follow directions. Do not give these medicines to children under 6 months of age without direction from your child's healthcare provider.

  • Steroids decrease swelling.

  • Incision and drainage may be needed to drain your peritonsillar abscess. Your healthcare provider will make a cut in the abscess to allow the pus to drain. Ask your healthcare provider for more information.

  • Surgery may be needed if other treatments do not work or your PTA happens again. Surgery may be done to remove your abscess completely. This may include removal of your tonsils.
