Tonsillectomy is a surgical procedure to remove the tonsils. The tonsils are part of the lymphatic system, which is responsible for fighting infection.
Tonsils are removed when a person, most often a child, has any of the following conditions:
Physicians are not in complete agreement on the number of sore throats that necessitate a tonsillectomy. Most would agree that four cases of strep throat in any one year; six or more episodes of tonsillitis in one year; or five or more episodes of tonsillitis per year for two years indicate that the tonsils should be removed.
A tonsillectomy is one of the most common surgical procedures among children. It is uncommon among adults. More than 400,000 tonsillectomies are performed
A tonsillectomy is usually performed under general anesthesia, although adults may occasionally receive a local anesthetic. The surgeon depresses the tongue in order to see the throat, and removes the tonsils with an instrument resembling a scoop.
Alternate methods for removing tonsils are being investigated, including lasers and other electronic devices.
Tonsillectomy procedures are not performed as frequently today as they once were. One reason for a more conservative approach is the risk involved when a person is put under general anesthesia.
In some cases, a tonsillectomy may need to be modified or postponed:
Persons are turned on their side after the operation to prevent the possibility of blood being drawn into the lungs (aspirated). Vital signs are monitored. Patients can drink water and other non-irritating liquids when they are fully awake.
Adults are usually warned to expect a very sore throat and some bleeding after the operation. They are given antibiotics to prevent infection, and some receive pain-relieving medications. For at least the first 24 hours, individuals are instructed to drink fluids and eat soft, pureed foods.
People are usually sent home the day of surgery. They are given instructions to call their surgeon if there is bleeding or earache, or fever that lasts longer than three days. They are told to expect a white scab to form in the throat between five and 10 days after surgery.
There is a chance that children with previously normal speech will develop a nasal-sounding voice. In addition, children younger than five years may be emotionally upset by the hospital experience. There are risks associated with any surgical procedure, including post-operative infection and bleeding.
Normal results include the correction of the condition for which the surgery was performed.
Morbidity other than minor post-surgical infection is uncommon. About one in every 15,000 tonsillectomies ends in death, either from the anesthesia or bleeding five to seven days after the operation.
There are no alternatives to surgical removal of the tonsils. Drug therapy may be used for recurrent infections involving the tonsils.

A tonsillectomy is performed in an outpatient facility associated with a hospital by a general surgeon or otolaryngologist (physician who specializes in treating disorders of the ear, nose, and throat).
