Definition    TOP

The tonsils are glands in the back of the throat. A tonsillectomy is the surgical removal of the tonsils.


Reasons for Procedure    TOP

Tonsillectomy is done when other methods fail for:

  • Repeated tonsil infections—the procedure may lower how many infections you have, but will not eliminate them
  • Peritonsillar abscess—pocket of infection spreading outside the tonsil
  • Enlarged tonsils that block the throat
