Ear tubes are, without question, one of the great success stories of pediatric medicine when used correctly. They are also, without much question at all, one of the most reflexively over-prescribed surgeries a child can undergo.
Insertion of tympanostomy tubes is the single most common reason a child in the United States goes under general anesthesia, with roughly 667,000 procedures performed annually on children under 15 — meaning by age three, nearly 1 in 15 American children already has a set (AAO-HNSF).
That is an extraordinary number of toddlers being wheeled into an OR for a condition that, in the majority of cases, was on track to resolve on its own.
I’ve been practicing pediatrics for more than thirty years, and I’ve watched this pattern repeat with almost comic predictability: fluid shows up behind the eardrum, a referral gets made, and a tiny tube gets inserted — often before anyone has actually waited long enough to see whether the child needed it at all.
The Actual Rule (It’s Not Complicated)
The evidence-based guideline, endorsed jointly by the American Academy of Pediatrics, the American Academy of Family Physicians, and the American Academy of Otolaryngology–Head and Neck Surgery, is refreshingly clear. Clinicians should not insert tubes for a single episode of otitis media with effusion (OME) — fluid without acute infection — lasting less than three months (AAO-HNSF Clinical Practice Guideline). Short-term fluid after a cold or an ear infection is normal. It usually clears up on its own. Tubes only become appropriate once fluid has persisted bilaterally for three months or longer and there’s documented hearing difficulty, or once other specific risk factors are present (AAO-HNSF).
Translation for the parents in the room: your pediatrician is supposed to watch and wait — reevaluating every three to six months — not schedule an OR slot the week fluid is first spotted on an exam (AAO-HNSF Guideline PDF). The guideline explicitly states this three-month observation window exists specifically “with the goal of avoiding unnecessary surgery.” Somebody wrote that sentence because unnecessary surgery was already happening at scale.
The Numbers Behind the “Unnecessary” Label
This isn’t a hunch. A landmark study led by Dr. Salomeh Keyhani and colleagues at Mount Sinai School of Medicine, published in the BMJ, reviewed detailed charts for 682 children who received tympanostomy tubes across five New York metropolitan area hospitals (Keyhani et al., BMJ 2008). The results were not subtle. Using explicit criteria developed specifically for the study, only 7.0% of the surgeries were classified as appropriate, 23.3% were of uncertain appropriateness, and a staggering 69.7% were classified as inappropriate. Measured against the 1994 guideline jointly issued by the American Academy of Pediatrics, American Academy of Family Physicians, and AAO-HNS, only 7.5% of the surgeries were concordant with the guideline (Keyhani et al., BMJ 2008).
Read that again: more than 9 out of 10 ear tube surgeries in this large, diverse metropolitan sample would not have been recommended under the guideline in force at the time. Children with acute otitis media had, on average, fewer than four infections in the year before their surgery — nowhere close to the threshold that would justify intervention. Children with fluid-only effusion had, on average, less than 30 consecutive days of fluid at the time of surgery, when the guideline calls for three to four months of persistence before tubes are appropriate (Keyhani et al., BMJ 2008).
Dr. Keyhani summarized the finding bluntly to the press: “We found that many children are getting surgeries for minor disease and the typical child who gets ear tube surgery does not have disease severe enough to warrant the operation. If the study findings could be applied to rest of the country, it would be particularly troubling” (The Hearing Review). She also noted this wasn’t a new discovery — a 1994 study had already found less than half of tympanostomy surgeries in the US were appropriate, meaning this is a problem that has persisted, essentially unaddressed, for decades (Keyhani et al., BMJ 2008).
The researchers’ conclusion, in their own understated academic language, put it plainly: “Regardless of whether current practice represents a substantial overuse of surgery or the guidelines are overly restrictive, the persistent discrepancy between guidelines and practice cannot be good for children” (Keyhani et al., BMJ 2008).
Why This Keeps Happening
Ear tube surgery is quick, generally well-tolerated, reasonably low-risk as outpatient pediatric surgery goes, and it resolves an extremely common complaint that exhausts parents: ear infections, sleepless nights, missed daycare, and the seemingly endless carousel of antibiotics. That combination makes it an appealing “fix” for both anxious parents and busy clinicians, particularly when watchful waiting means telling an already-frustrated parent to come back in three months and watch their kid tug at their ear a while longer.
But convenience is not the same as clinical necessity, and the guideline’s own authors built the three-month rule specifically because most OME resolves on its own. Tubes are not without risk either — they carry chances of chronic drainage, tympanosclerosis (scarring of the eardrum), and the eventual need for the tubes themselves to be removed or for the eardrum to be repaired if they fall out prematurely or leave a persistent perforation.
What I Tell Parents
If ear tubes are being recommended for your child, ask the same two things I’d ask if I were the one hearing the recommendation as a parent, not the one making it as a doctor. First: “How long has the fluid actually been documented as present — not suspected, documented?” Second: “Has a hearing test confirmed there’s a real hearing deficit, or are we assuming one?” If the fluid has been there for six weeks and nobody’s run a hearing test, you are being offered general anesthesia and a surgical procedure on the strength of impatience, not evidence.
There are absolutely children who benefit enormously from tubes — chronic bilateral effusion with real hearing loss, recurrent severe infections despite appropriate treatment, or documented speech and language delay tied to hearing difficulty. For those kids, tubes are one of the more gratifying, high-impact interventions in pediatrics. But “the fluid has been there since the pediatrician saw it three weeks ago” is not that child. It’s just a family that got tired of waiting — and a system that, roughly seven times out of ten apparently, is happy to skip the waiting for them.
