After a winter of repeated tonsillitis, almost every parent reaches the same point: surely it would be simpler to just take them out. Sometimes that is the right answer. Often the picture changes within a year on its own, because tonsil tissue naturally shrinks from around age seven or eight, and a child who looked like a clear surgical candidate at five looks fine again by seven without anyone touching them.
The job of the GP or ENT surgeon is to use the formal criteria — and a clear-eyed look at how disruptive the episodes really are — to find the children for whom surgery is genuinely worth doing. Surgery has a small but real bleed risk. Skipping it when it is needed leaves a child miserable; doing it when it is not is an avoidable operation on a healthy throat.
Healthbooq (healthbooq.com) covers ENT surgery and recovery in plain language for families.
What the Tonsils and Adenoids Are For
The tonsils sit on either side of the back of the throat — the two pink lumps you can see when a child says "ahh." The adenoids are the same kind of lymphoid tissue, but at the back of the nose, above the soft palate, where you cannot see them without a scope. Both are part of the immune ring of tissue guarding the airways.
This tissue is biggest in early childhood, peaks around ages three to seven, then steadily shrinks. That is why a child whose nose was constantly blocked at four can sleep with their mouth shut at eight without any treatment at all.
Recurrent Tonsillitis: When Surgery Is on the Table
Tonsillitis means infected, inflamed tonsils — usually with fever, a clearly sore throat, swollen tender neck glands, and often white pus on the tonsils themselves. Roughly two-thirds of episodes are viral; about a third are caused by Group A streptococcus, which is the only one that benefits from antibiotics.
NICE NG34 borrows the Paradise criteria for when to consider referring for tonsillectomy:
- 7 or more episodes in the past 12 months, or
- 5 or more per year for two consecutive years, or
- 3 or more per year for three consecutive years.
And — this is the part that gets skipped — each episode has to be a proper one: documented fever, exudate or large nodes, and disruptive enough to keep the child off school or out of normal activities. A weekend of "the throat looks a bit red" does not count.
Hitting the threshold is a reason to be referred, not an automatic ticket to theatre. The ENT surgeon weighs frequency, severity, the trajectory (getting worse, or settling?), missed school, and the family's experience against the natural history. About a third of children referred at the threshold will have outgrown the pattern by the time the decision is made.
Quinsy
A peritonsillar abscess — quinsy — is a pocket of pus between the tonsil and the muscle behind it. The throat hurts on one side, the voice goes muffled ("hot potato voice"), and the child often cannot open their mouth fully. It needs urgent ENT review for drainage. A second quinsy is usually treated as an indication for tonsillectomy; a single one alone, opinions vary.
Obstructive Sleep Apnoea: A Different Reason to Operate
Big tonsils and adenoids are the most common cause of obstructive sleep apnoea in children. The picture: heavy snoring most nights, audible pauses, gasps, restless sleep, mouth breathing, sweating, and daytime tiredness or behaviour issues that look a lot like ADHD. Confirmed OSA — usually with overnight oximetry — is a stronger and more urgent indication for adenotonsillectomy than recurrent infection, because untreated OSA affects growth, learning, and cardiovascular load.
Adenoidectomy on its own can be enough for chronic nasal obstruction, persistent mouth breathing, the developing "adenoid face" (long face, open mouth, nasal voice), or to cut the recurrence rate of glue ear after grommets.
What the Operation Involves
Tonsillectomy in children is a day case under general anaesthetic in most centres, with overnight stay reserved for younger children, OSA cases, or those who live far from the hospital. The tonsils are dissected free; bipolar diathermy seals the bleed points as the surgeon goes. Cold steel and coblation are alternatives — the bleed-rate differences between techniques are small, and the choice is mostly the surgeon's preference.
Adenoidectomy adds a few minutes — the surgeon scoops the adenoid pad out from behind the soft palate using a curette or suction diathermy. Total theatre time for both is usually 30 to 45 minutes.
What Recovery Actually Looks Like
The first night and the next 7 to 10 days are genuinely painful. Throats hurt to swallow, ears hurt (referred pain — the throat and ear share a nerve), and most children eat less for the first few days. Counterintuitively, eating helps: the chewing and swallowing keeps the surfaces moving and the muscles working, and dehydration makes the pain worse, not better.
What works for the first week:
- Regular paracetamol and ibuprofen, alternating, on the clock — not waiting for pain to build. Ibuprofen is fine after tonsillectomy despite older anxieties; current evidence does not show a higher bleed rate.
- Soft food, but not bland. Pasta, mashed potato, scrambled egg, ice cream, yoghurt. Toast is too sharp; citrus stings.
- Plenty of fluids. Cold drinks are usually easier than warm.
- A white-grey coating where the tonsils were — that is the healing slough, not infection. It looks alarming and smells off, but it lifts naturally over the second week.
- Two weeks off school, away from siblings with colds, no swimming, no rough play.
The One Thing That Has to Trigger A&E
Bleeding from a healing tonsil bed five to ten days after surgery is the complication you cannot wait out. The scabs lift as the throat heals, and in 2 to 5 percent of children a small bleed point opens up — sometimes alarmingly fast.
Any blood at all from the mouth or throat after tonsillectomy goes straight to A&E, not the GP, not "let's see if it stops." Even blood-tinged spit. Even if it has stopped by the time you would leave the house. A small bleed often warns of a bigger one within hours, and a bigger one is genuinely dangerous in a small child. Hospitals know to take this seriously and have a low threshold for admission and theatre review.
Earlier bleeding (within 24 hours) is the other category — it almost always happens before you leave the ward, which is part of why young children are watched for several hours post-op.
Pain Trajectory Day by Day
A useful rough map:
- Day 1–2: throat sore, child sleepy from anaesthetic, eating little.
- Day 3–5: typically the worst. Pain often peaks here, not on day one. Ear pain common.
- Day 6–8: scabs starting to separate. Pain often briefly worsens before improving.
- Day 9–10: most children turning the corner.
- Day 14: usually back at school, eating normally.
If pain is escalating after day 7, the child has a fever, or there is any bleeding, it is a reason for review.
What to Expect Long-Term
Children selected by the Paradise criteria typically get fewer sore throats afterward — though not zero, because tonsils were never the only source of throat infections. For OSA, the change is usually dramatic: snoring stops, sleep settles, and parents notice the difference within a few weeks. Children operated on for adenoid-related blockage often catch up on facial development and breathe through their noses for the first time in years.
The decision to operate is one of those where a careful match between the child's pattern and the criteria matters more than any single rule of thumb. If the threshold is borderline and the trajectory is improving, waiting is often the right call. If sleep is broken every night and the child is exhausted, surgery is the right call sooner rather than later.
Key Takeaways
NICE recommends considering tonsillectomy after 7 disabling sore throats in 12 months, 5 a year for two years, or 3 a year for three years (the Paradise criteria) — and most children below those thresholds outgrow the problem without surgery. Sleep apnoea caused by big tonsils and adenoids is a separate, stronger indication. The operation is usually a day case; recovery takes about 10 days and is genuinely painful. The bleed parents need to know about happens 5 to 10 days post-op when the scabs lift — any blood from the mouth means A&E now, not a watch-and-wait.
