  • Fasting before surgery, such as avoiding food or drink after midnight the night before
  • Whether you need a ride to and from surgery


The doctor may give:

  • A sedative—you will feel relaxed
  • Local anesthesia—the area will be numbed
  • General anesthesia—you will be asleep

Description of the Procedure

The doctor will open the mouth. Medicine will be sprayed over the area to make it numb. A special tool will be used to hold the tonsils. The tonsils will be removed with a scalpel or electric current. Open area will be closed with stitches.
