Tonsillectomy is a surgical procedure that involves the removal of tonsils to treat sleep-related breathing issues or frequent infections. While tonsillectomies are less common today, over 500,000 procedures are still performed each year in the US. Before the procedure, a medical evaluation is required to review sleep study records, medical history, and in many cases, a diagnostic evaluation with a drug-induced sleep endoscopy. Tonsillectomy is performed under general anaesthesia and usually takes 20 to 30 minutes. The recovery period can last up to two weeks, and patients are advised to take time off work and avoid strenuous activities during this time.

What You'll Learn

What is a tonsillectomy?
A tonsillectomy is a surgical procedure that involves the removal of the tonsils—the round, fleshy masses in the back of the throat. Tonsils are usually two in number, with one on each side. However, in some cases, a partial tonsillectomy may be performed, where only a part of the tonsils is removed.
Tonsillectomies are recommended for two primary reasons: to treat sleep-related breathing disorders such as sleep apnea, and to reduce the risk of infection in people with frequent or chronic tonsillitis. While tonsillectomies are more common in children, adults can also benefit from the procedure.
The procedure is performed under general anesthesia and typically takes about 20 to 30 minutes. Surgeons use various methods, including electrocautery, cold knife dissection, snare tonsillectomy, and harmonic scalpel, among others. After the surgery, patients are usually kept overnight in the hospital for observation and pain management. The recovery process can take up to two weeks, during which patients may experience some discomfort and are advised to consume soft, cool foods and plenty of fluids.

Why is a tonsillectomy done?
Tonsillectomy is the surgical removal of the tonsils—the round, fleshy masses in the back of the throat. While tonsillectomies are less common than they used to be, they are still performed today, with over 500,000 procedures taking place each year in the US.
Tonsillectomy is recommended for two main reasons:
- To treat breathing-related sleep disorders, such as sleep apnea.
- To reduce the risk of infection in people with frequent or chronic tonsillitis.
Sleep Disorders
Tonsillectomy is one of the most common procedures for obstructive sleep apnea. Enlarged tonsils can cause blockage of the airway, leading to sleep apnea. Removing the tonsils can open up space for breathing and improve sleep apnea.
Tonsillitis
Tonsils help protect against infections, but they can also become infected themselves, leading to tonsillitis. Tonsillectomy may be considered if a person experiences frequent tonsil infections (e.g., 7 or more times in 1 year) or misses a lot of school or work due to tonsillitis.
Other Reasons
Tonsillectomy may also be recommended if a person has an abscess or growth on the tonsils, gets frequent tonsil stones, or has trouble breathing and sleeping due to the tonsils blocking the airway.

What happens during a tonsillectomy?
Tonsillectomy is the surgical removal of the tonsils, which are round, fleshy masses in the back of the throat. The procedure is performed under general anaesthesia and usually takes 20 to 30 minutes.
There are several methods that can be used to perform a tonsillectomy:
- Electrocautery: This method uses heat to remove the tonsils and stop any bleeding.
- Cold knife (steel) dissection: A surgeon uses a scalpel to remove the tonsils and then stops the bleeding with electrocautery or sutures.
- Snare tonsillectomy: A surgeon uses a thin wire loop to clamp off the tonsil and reduce bleeding.
- Harmonic scalpel: This method uses ultrasonic vibrations to remove the tonsils and stop bleeding.
- Radiofrequency ablation techniques: This method uses a radiofrequency device to remove the tonsils and minimise tissue damage.
- Carbon dioxide lasers: This method uses lasers to remove the tonsils.
- Microdebrider: This method uses a combination of suction and cutting to remove the tonsils.
After the tonsillectomy, the patient is transferred to a recovery area where their vital signs are monitored. Tonsillectomy is usually an outpatient procedure, but patients may be kept in the hospital overnight for observation. The recovery process typically takes up to two weeks, during which patients should consume soft, cool foods and drinks to aid healing.

What happens after a tonsillectomy?
Tonsillectomy is the surgical removal of the tonsils, two round, fleshy masses in the back of the throat. The procedure is usually carried out under general anaesthetic and can take up to 30 minutes. It is often used to treat sleep-related breathing issues, such as sleep apnea, or to reduce the risk of infection in people with frequent or chronic tonsillitis.
After a tonsillectomy, you will be moved to a recovery area where medical staff will monitor your vital signs and check for any postoperative complications. Tonsillectomy is usually an outpatient procedure, meaning that you can go home on the same day. However, if complications arise, you may be kept in the hospital overnight for observation.
The recovery time for a tonsillectomy is up to two weeks, although this can vary depending on the type of tonsillectomy, your body's healing capacity, and whether any complications arise. Here is a general timeline of what to expect during the recovery process:
- One to two days after tonsillectomy: You may experience difficulty speaking or hoarseness, as well as a feeling of fullness in your throat due to swelling.
- Three to five days after tonsillectomy: The sore throat will likely continue and may worsen around day three or four.
- Five to ten days after tonsillectomy: Mild bleeding may occur when the scabs fall off.
It is important to drink plenty of fluids and eat soft, cool foods during the first week after surgery. Solid foods can be introduced as comfort levels allow, but hard and spicy foods should be avoided as they can irritate the surgical area. It is recommended to take at least 10 days off work or school following the procedure to reduce the risk of infection.
Possible Risks and Complications
Although rare, there are some possible risks and complications associated with tonsillectomy, including:
- Excessive bleeding during or after the procedure.
- Swelling of the tongue or the roof of the mouth.
- Reaction to anaesthesia.
- Post-surgical bleeding.

What are the advantages and disadvantages of a tonsillectomy?
Tonsillectomy is a common procedure to treat breathing-related sleep disorders, such as sleep apnea, and to reduce the risk of infection in people with frequent or chronic tonsillitis. While tonsillectomies are less common today than they were a few decades ago, they are still performed on over 500,000 people every year in the US.
Advantages of Tonsillectomy
Tonsillectomy can offer many benefits, including:
- Better sleep quality
- Improved quality of life
- Reduced risk of infection
- Lesser dependency on medicines
- Improved sleep patterns
- Lesser chances of skipping work or school
Disadvantages of Tonsillectomy
Some possible risks of tonsillectomy include:
- Excessive bleeding during or after the procedure
- Swelling of the tongue or the roof of the mouth
- Reaction to anesthesia
- Post-surgical bleeding
- Sore throat
- Pain
- Short-term complications, such as soreness in the throat, lethargy, and difficulty in swallowing
There are also some long-term health risks associated with tonsillectomy, especially when performed during childhood. Research has found that tonsillectomy is associated with higher levels of allergic, respiratory, and infectious diseases later in life. Specifically, tonsillectomy can almost triple the relative risk for diseases of the upper respiratory tract like asthma, influenza, pneumonia, and chronic obstructive pulmonary disorder (COPD).

Frequently asked questions
Yes, a sleep study is required before tonsillectomy. Tonsillectomy is a surgical procedure that removes inflamed, infected, or problematic tonsils. It is done to treat sleep-related breathing issues or frequent infections. A sleep study is necessary to establish a definitive diagnosis of sleep-disordered breathing.
During a sleep study, you will be connected to equipment that will monitor your brain activity, heart rate, breathing, and movements during sleep. This information will help diagnose any sleep disorders you may have.
Before the sleep study, you should avoid caffeine and naps during the day. You should also refrain from strenuous exercise and avoid consuming large meals close to bedtime. On the day of the study, bring comfortable clothes and any items that may help you relax, such as a book or music.
After a tonsillectomy, you will be transferred to a recovery area where your vital signs will be monitored. Tonsillectomy is usually an outpatient procedure, but if there are any complications, you may be kept in the hospital overnight for observation. You can expect some discomfort and pain after the surgery, which can be managed with medication. It is important to rest and drink plenty of fluids during the recovery period.
