Peritonsillar Abscess

What is a Peritonsillar Abscess?

  • A peritonsillar abscess forms in the tissues of the throat next to one of the tonsils.
    • An abscess is a collection of pus that forms near an area of infected skin or other soft tissue.
  • The abscess can cause pain, swelling, and, if severe, blockage of the throat. If the throat is blocked, swallowing, speaking, and even breathing become difficult.
  • When an infection of the tonsils (known as tonsillitis) spreads and causes infection in the soft tissues, a peritonsillar abscess may result.
  • Peritonsillar abscess is relatively common in adults but rare in infants and young children.
