A tonsillectomy is surgery to remove the tonsils. The
adenoids may or may not be removed at the same time.
This topic is about surgery to remove the tonsils, not the adenoids.
For children, a
general anesthetic is always used. It makes the child sleep during the surgery. Adults may need only a
local anesthetic to numb the throat.
Tonsillectomy is often done as an outpatient
surgery. But some people may need to stay overnight in the hospital.
A person can expect to have a very sore throat after surgery. It may last for several days.
This may affect the sound and volume of the voice. It can make it harder to eat and drink. The person may also have bad breath for a
few days after surgery. There is a very small risk of serious bleeding after
A child who has a tonsillectomy may not feel well
for a week to 10 days. But if the child is feeling well after the first few days,
there is no need to restrict his or her activity or to keep the child at home.
A tonsillectomy may be done when:
Large tonsils are not a reason to have a tonsillectomy
unless they are causing one of the above problems or they are blocking the
upper airway. This blockage may cause
sleep apnea or problems with eating.
Children who have their tonsils removed
for repeated throat infections may have fewer and less severe
strep throat infections for at least 2 years. But over
time, many children who do not have surgery also have fewer throat
Adults who have their
tonsils removed after repeated strep throat infections don't get as many new
infections as adults who do not have the surgery. And adults who had the
surgery also don't get sore throats as often.footnote 2
Some bleeding is a normal risk after a tonsillectomy. This is common, especially when the healed
scab over the cut area falls off.
Less common or rare risks
When you are trying to decide
whether to have a child's tonsils removed, you might want to think about:
For children and adults, the risks of surgery must also be weighed against the risks
of leaving the tonsils in. In some cases where strep throat keeps coming back,
surgery may be the best
choice. This is especially true if there are also other problems from the tonsils.
Some people think that removing the tonsils may hurt the
immune system, but research does not support this.
