Nothing says “modern medicine” quite like removing a perfectly innocent piece of lymphoid tissue from a five-year-old because they had a sore throat twice last winter.
Tonsillectomy is one of the most common surgeries performed on American children — more than 500,000 a year at its peak, still hundreds of thousands annually today — and it has the rare distinction of being both wildly popular and, according to the actual evidence, wildly overused (AAFP; AAO-HNSF).
I’ve been a pediatrician for over thirty years. In that time I have watched the indications for this surgery shift, get studied, get codified into a formal guideline, and then get ignored by a shocking number of the people doing the operating and the referring. So let’s talk about what the actual criteria are — versus what apparently counts as “close enough” in a lot of exam rooms.
The Criteria That Actually Exist (Yes, There Are Real Ones)
Despite what waiting-room small talk might suggest, tonsillectomy for recurrent throat infection is not supposed to be offered because a child had “a lot of sore throats, doctor, I mean a lot.” There is an actual evidence-based standard, known as the Paradise criteria, endorsed by the American Academy of Otolaryngology–Head and Neck Surgery Foundation (AAO-HNSF Clinical Practice Guideline). A child is a candidate if they have had:
7 or more documented episodes of sore throat in the past year, or
5 or more episodes per year for 2 consecutive years, or
3 or more episodes per year for 3 consecutive years
And — this is the part that gets skipped constantly — each episode has to be documented, and accompanied by at least one of: a fever over 101°F, tender or enlarged cervical lymph nodes, visible tonsillar exudate, or a positive strep test (AAFP; AAO-HNSF). A sore throat that Mom remembers from “sometime last spring” does not count. Twelve months of watchful waiting is the recommended default for children who don’t meet this threshold (AAFP).
The other major, evidence-supported indication is obstructive sleep-disordered breathing — genuine airway obstruction from enlarged tonsils, ideally confirmed with a sleep study when the picture is unclear (Texas Children’s Hospital). Recurrent peritonsillar abscess, PFAPA syndrome, and suspected malignancy round out the legitimate list (Pediatric Clinics of North America).
That’s it. That’s the real list. Notice what’s not on it: snoring that isn’t actually apnea, tonsil stones your child’s grandmother finds alarming, mild mouth breathing, one bad winter, or “well, we’re already doing the adenoids, might as well.”
Now Here’s What’s Actually Happening
A 2018 study out of the University of Birmingham reviewed the records of 1.6 million children in the UK and found that only 11.7% of children who had a tonsillectomy actually met the evidence-based criteria for one (British Journal of General Practice; BBC News). Let that sink in: roughly seven out of every eight tonsillectomies performed were not supported by the criteria that exist specifically to guide this decision. Almost half of the children who had the surgery had experienced just two to four sore throats in a single year — nowhere close to threshold (HospiMedica). One in ten had exactly one documented sore throat before someone reached for a scalpel (Discover Magazine).
And in a delightful bit of irony, the same study found the system fails in both directions: of the children who did meet criteria and were severely affected, only about one in seven ever actually got the surgery (British Journal of General Practice). So we are simultaneously operating on children who don’t need it and leaving genuinely miserable kids untreated. Efficient.
This isn’t just a UK phenomenon or ancient history. Landmark research from Dartmouth going back decades — and updated since — found that tonsillectomy rates vary enormously between neighboring communities for reasons that have nothing to do with how sick the kids actually are. In one Vermont town, 20% of children had their tonsils removed by age 15; in the town next door, 60% did (Lown Institute). Unless one town’s water supply causes uniquely aggressive tonsils, that’s not a medical variable. That’s a “which ENT you happened to see” variable.
Why Does This Keep Happening?
Take your pick of reasons, none of them flattering: clinical inertia, doing what’s always been done, a lack of familiarity with the actual updated guideline, parental pressure after one miserable strep season, or the simple fact that “let’s just take them out” is a satisfying, definitive-feeling answer to an exhausted parent compared to “let’s document three more episodes over the next two years and see.” One study bluntly noted that “why so many children are getting unnecessary tonsillectomies isn’t quite clear, but it could simply be a lack of information among doctors” (Discover Magazine).
Here’s the thing this casual attitude conveniently glosses over: tonsillectomy is not a risk-free trim. One in five children who have the surgery experience a complication — most commonly breathing difficulty, affecting about one in ten, and bleeding, affecting about one in twenty, sometimes days after the child has already gone home (Harvard Health). Long-term Danish data following roughly a million children found that those who’d had a tonsillectomy or adenoidectomy had two to three times the risk of upper respiratory tract disease later in life compared with children who kept their tonsils (Lown Institute). And for the children with milder, less frequent sore throats, the evidence actually shows the surgery’s benefit doesn’t outweigh the recovery-week pain and risk — the sore throats they were having would likely have resolved on their own (Wikipedia summarizing Cochrane data; University of Birmingham).
What I Tell Parents
If your pediatrician or ENT is recommending a tonsillectomy for recurrent throat infections, ask two questions before you agree to anything. First: “Has this been documented as meeting the 7-5-3 criteria — with confirmed fever, exudate, adenopathy, or a positive strep test for each episode?” Second: “Have we tried twelve months of watchful waiting first?” If the honest answer is no to both, you are being offered elective surgery on the strength of vibes, not evidence.
If the concern is sleep-disordered breathing rather than infections, ask whether a sleep study has been considered, especially if the severity of what’s being described doesn’t quite match what you’re actually observing at home.
Tonsils are not a design flaw. They are not spare parts sitting around waiting to become a problem. For the right child — one who is genuinely, repeatedly, documentedly suffering — this surgery is one of the more gratifying things I get to recommend as a pediatrician, because the improvement in quality of life can be real and meaningful. But “the right child” is a specific, defined, evidence-based category. It is not “had a rough winter” or “grandma is worried about the tonsil stones.” Know the criteria, ask for the documentation, and don’t let anyone hand your child a surgery because it was easier than counting to seven.
