Peritonsillar abscess

Peritonsillar Abscess

Peritonsillar abscess

A peritonsillar abscess is a collection of pus that forms in tissues around the tonsils. Although uncommon, it can occur as a result of strep throat. The abscess can cause severe pain and an inability to swallow, and you may become very ill.

A peritonsillar abscess may be diagnosed and treated with either a needle aspiration or a small incision. A needle aspiration is a procedure that uses a needle to drain the abscess. A course of antibiotics is given after the procedure. If a needle aspiration is not used, a peritonsillar abscess may be treated with a simple procedure in which a small incision is made in the abscess to drain it, followed by a course of antibiotics.

Surgery to remove the tonsils (tonsillectomy) may be done if you are concerned that the peritonsillar abscess will recur. But tonsillectomy is not needed if you've only had one abscess. Most people who have had an abscess do not have another one.

How can you care for peritonsillar abscess in children?

  • If the doctor prescribed antibiotics for your child, give them as directed. Do not stop using them just because your child feels better. Your child needs to take the full course of antibiotics.
  • Be safe with medicines. Give pain medicines exactly as directed.
    • If the doctor gave your child a prescription medicine for pain, give it as prescribed.
    • If your child is not taking a prescription pain medicine, ask your doctor if your child can take an over-the-counter medicine.
    • Do not give aspirin to anyone younger than 20. It has been linked to Reye syndrome, a serious illness.
  • Make sure your child gets lots of rest.
  • Follow your doctor's instructions if the abscess was drained through a needle or small incision.
  • While your child's throat is very sore, use liquid nourishment such as soup or high-protein drinks.
