Tonsils are removed through a short surgery called a tonsillectomy, performed under general anesthesia and typically lasting 20 to 30 minutes. The surgeon accesses the tonsils through the open mouth, so there are no external incisions or visible scars. Several different techniques exist, but they all share the same basic goal: separating the tonsil tissue from the surrounding throat wall and controlling any bleeding.
Why Tonsils Get Removed
The most common reason is recurrent throat infections. Clinical guidelines from the American Academy of Otolaryngology recommend considering tonsillectomy when a person has had at least 7 episodes of strep or tonsillitis in a single year, at least 5 episodes per year for two consecutive years, or at least 3 episodes per year for three years running. Each episode needs to be documented with at least one objective sign: a fever over 101°F, swollen neck glands, pus on the tonsils, or a positive strep test.
If infections fall below those thresholds, watchful waiting is the standard recommendation. That said, other factors can tip the decision toward surgery, including allergies to multiple antibiotics, a history of abscesses near the tonsils, or a rare condition that causes recurring fevers and mouth sores. Severely enlarged tonsils that block breathing during sleep are another common reason, particularly in children.
The Main Surgical Techniques
All tonsillectomy methods are done through the mouth while you’re fully asleep. The surgeon holds the tonsil with a grasping instrument and separates it from the thin layer of tissue connecting it to the throat wall. How they do that separation, and how they stop bleeding, is where the techniques differ.
Cold Knife Dissection
This is the traditional approach. The surgeon uses blunt metal instruments to peel the tonsil away from the throat wall along a natural tissue plane, working from the top of the tonsil down to the bottom. A wire loop called a snare cinches around the base to remove the last attachment. Because no heat is involved, any bleeding vessels are tied off individually with sutures. The technique produces less heat damage to surrounding tissue, which can mean less post-operative pain for some patients.
Electrocautery
This method uses an electrical current passed through a specialized forceps to simultaneously cut tissue and seal blood vessels with heat. The surgeon works through the same tissue plane as the cold technique but uses low-energy electrical current (typically around 25 watts) to coagulate blood vessels as they go. The advantage is faster bleeding control during surgery, which often means a shorter procedure. The tradeoff is that heat can affect nearby tissue and potentially contribute to more soreness during healing.
Coblation
Coblation uses radiofrequency energy combined with a saltwater solution to break down tissue at a lower temperature than traditional electrocautery. Because it operates at roughly 40 to 70°C instead of the several hundred degrees generated by standard cautery, it causes less thermal injury to the surrounding throat tissue. Coblation can also be used for partial tonsil removal (intracapsular tonsillectomy), where the surgeon shaves down the tonsil tissue while leaving a thin protective layer over the throat wall muscles.
Microdebrider
A microdebrider is a powered rotating blade inside a small tube that shaves away tonsil tissue. It’s most commonly used for partial removal rather than taking out the entire tonsil. Like coblation, it tends to preserve more of the surrounding tissue, which can reduce pain and speed recovery.
What Happens During the Procedure
You’ll receive general anesthesia, meaning you’re completely asleep and feel no pain. A mouth retractor holds your jaw open so the surgeon can see both tonsils clearly. Most surgeons also give a single dose of an anti-inflammatory steroid during the operation, which has been shown to significantly reduce post-operative nausea, vomiting, and pain while helping patients start eating and drinking sooner.
The entire procedure typically takes 20 to 30 minutes, though it can run longer in some cases. After the tonsils are removed, the surgeon inspects the tonsillar beds (the shallow depressions left behind) to confirm all bleeding has stopped. Most tonsillectomies are outpatient, meaning you go home the same day once you’re awake, alert, and able to swallow fluids.
Bleeding Risk
Bleeding is the most significant complication. Primary bleeding, which occurs within the first 24 hours, happens in roughly 0.2% to 2% of cases. Secondary bleeding, which occurs after the first day (usually between days 5 and 10 as scabs separate), carries a 0.1% to 3% risk. Secondary bleeding is more common and tends to coincide with the natural shedding of the healing scabs. Most episodes are minor and stop on their own, but some require a return to the operating room.
How the Throat Heals
Thick, yellow-white scabs form over the tonsillar beds within the first day or two after surgery. These scabs look concerning to many patients, but they’re a normal and expected part of healing. They remain in place for about 5 to 10 days, then fall off gradually in small pieces. You might notice small flecks in your saliva or swallow them without realizing. The underlying tissue continues to heal beneath them.
Pain is usually worst between days 3 and 7, often peaking around days 5 to 6 as swelling and scab separation overlap. Ear pain is common during this stretch, not because anything is wrong with the ears, but because the throat and ears share nerve pathways. Most adults describe the overall recovery as taking about two weeks before they feel close to normal, while children often bounce back a few days sooner.
Managing Pain After Surgery
The standard approach is alternating acetaminophen (Tylenol) and ibuprofen (Advil or Motrin) on a scheduled, round-the-clock basis rather than waiting until pain becomes severe. Research shows that alternating these two medications every four hours provides effective relief while also lowering the rate of post-operative bleeding compared to more frequent dosing schedules. Ibuprofen was historically avoided after tonsillectomy due to bleeding concerns, but current evidence and guidelines support its use, and studies have found no increase in emergency visits for pain or dehydration when it’s part of the regimen.
Staying well-hydrated is critical. Swallowing hurts, which makes many patients (especially children) reluctant to drink, but dehydration worsens pain and is one of the most common reasons people end up back in the emergency room. Small, frequent sips are more manageable than large gulps.
What to Eat During Recovery
Soft, cool, and bland foods are the safest choices for the first week or two. Good options include ice cream, yogurt, pudding, mashed potatoes, scrambled eggs, applesauce, soft cooked vegetables, and strained soups. Cold foods can feel soothing on the throat, while warm (not hot) broth provides hydration and some nutrition.
Foods to avoid include anything sharp-edged (chips, pretzels, toast, dry cereal, popcorn, pizza crust), anything very hot, and heavily spiced dishes. These can irritate the healing tissue or dislodge scabs prematurely. Citrus fruits and juices are safe in theory but tend to sting. It’s also worth skipping red-colored drinks and popsicles, not because they’re harmful, but because they make it impossible to tell whether you’re seeing a normal red beverage or actual bleeding.
