How Long Do Ear Tubes Stay in Kids’ Ears?

By Sarah Mitchell · July 9, 2025

Why This Question Keeps Parents Up at Night — And Why It Matters More Than Ever

If you've ever Googled how long do tubes stay in kids ears, you're not alone — and you're likely holding your breath after surgery, watching for signs of trouble, or wondering if that tiny silver speck behind your child’s eardrum is still doing its job. Tympanostomy tubes (commonly called 'ear tubes') are one of the most frequent outpatient surgeries performed on children in the U.S., with over 600,000 procedures annually — yet many parents receive only vague reassurance like 'they’ll fall out on their own' without concrete timelines, warning signs, or realistic expectations. That uncertainty fuels anxiety: Is it normal for tubes to stay in 18 months? Should you worry if they’re still there after two years? What happens if they don’t come out — or worse, get blocked or infected? In this guide, we cut through the ambiguity with data-driven timelines, real-world case studies from pediatric ENT practices, and actionable steps you can take *today* to support your child’s ear health — all grounded in American Academy of Pediatrics (AAP) and American Academy of Otolaryngology–Head and Neck Surgery (AAO-HNS) clinical guidelines.

What Ear Tubes Actually Do — And Why Timing Is Everything

Before diving into duration, it’s essential to understand *why* tubes are placed — because that directly shapes how long they need to stay in. Ear tubes are tiny, hollow cylinders (usually made of silicone or fluoroplastic) surgically inserted through the eardrum to ventilate the middle ear, drain accumulated fluid, and prevent recurrent acute otitis media (AOM) or chronic otitis media with effusion (OME). According to Dr. Elena Ramirez, a board-certified pediatric otolaryngologist and clinical professor at Stanford Children’s Health, 'Tubes aren’t a permanent fix — they’re a temporary bridge. Their job is to buy time while the child’s Eustachian tube matures, immune system strengthens, and environmental triggers (like daycare exposure or allergies) stabilize.' Most children under age 5 have narrower, more horizontal Eustachian tubes that don’t drain efficiently — a developmental reality that improves naturally by age 6–7. So tube duration isn’t arbitrary; it’s calibrated to match this biological window.

That said, 'temporary' doesn’t mean predictable. A 2023 multicenter study published in Pediatrics tracked 1,247 children with bilateral tube placement and found median retention time was 14.2 months — but individual variation spanned from just 4 months to over 36 months. Why such range? Three key factors: tube type (short-term vs. long-term), age at insertion, and underlying risk profile. For example, children with cleft palate, Down syndrome, or chronic sinusitis often require longer-duration tubes — not because of surgical error, but due to persistent anatomical or immunologic challenges.

The Two Main Tube Types — And Exactly How Long Each Stays In

Not all ear tubes are created equal — and confusing them is where many parents misinterpret timelines. There are two clinically distinct categories, each with different design lifespans and indications:

Short-term tubes (e.g., Shepard, Armstrong, Dornhoffer): Typically 1–2 mm in length, with flanged ends. Designed to stay in place for 6–18 months before spontaneously extruding as the eardrum grows outward (a natural process called epithelial migration).
Long-term tubes (e.g., T-tubes, Goode T-tube, Triune): Longer (up to 4 mm), with a central shaft and flanges at both ends. Intended for children who’ve failed short-term tubes or have complex anatomy. These may remain in place for 2–4 years — and sometimes require manual removal.

A critical nuance: 'Long-term' doesn’t mean 'permanent.' Even T-tubes eventually loosen — but because they sit deeper in the eardrum, spontaneous extrusion is less reliable. As Dr. Ramirez explains, 'I tell families: Short-term tubes are like a timed-release capsule — they’re built to exit. Long-term tubes are more like scaffolding — they support healing until the structure is strong enough to stand alone. But scaffolding still comes down — it just needs supervision.'

What Happens When Tubes Fall Out — And How to Spot Problems Early

Tubes don’t 'disappear' — they extrude, meaning the eardrum gradually pushes them outward until they drop into the ear canal. Most parents never see this happen. Instead, they notice subtle shifts: improved hearing clarity, fewer ear infections, or the sudden absence of drainage (if there had been any). But extrusion isn’t always smooth. Here’s what to monitor closely — and what warrants an ENT visit within 48 hours:

Early extrusion (before 4 months): Could signal improper placement, infection, or tube migration. May require reinsertion if fluid returns.
No extrusion by 24 months (for short-term tubes): Not automatically alarming — but warrants evaluation. An audiogram and otoscopic exam will assess eardrum mobility and middle-ear status.
Tubes appearing 'buried' or covered in crust: Often indicates biofilm buildup or chronic otorrhea (drainage). Requires cleaning + topical antibiotic drops — not oral antibiotics, per AAP 2022 guidelines.
New-onset hearing loss or balance issues after extrusion: May suggest persistent effusion or tympanic membrane scarring (tympanosclerosis), which affects ~15% of children post-tubes but rarely impacts function.

Real-world example: Maya, age 4, had bilateral short-term tubes placed at 28 months for 9 ear infections in 12 months. At her 15-month follow-up, her ENT noted one tube had extruded cleanly; the other remained in place but showed no drainage or inflammation. Instead of rushing removal, they opted for watchful waiting — and it extruded spontaneously at 19 months. Her audiogram confirmed stable hearing, and she’s had zero infections in the 14 months since. This illustrates why patience — guided by objective metrics — beats calendar-based assumptions.

Care Timeline Table: What to Expect Month-by-Month After Tube Placement

Time Since Placement	What’s Normal	Red Flags Requiring ENT Review	Recommended Action
0–4 weeks	Mild ear discomfort; clear or slightly cloudy drainage; hearing improvement often noticeable within 72 hours	Fever >102°F, severe pain unrelieved by ibuprofen, bloody or foul-smelling discharge	Call ENT same-day; may need culture + topical drops
1–6 months	Occasional clear/yellow drainage (especially after swimming or colds); no pain; stable hearing	Drainage lasting >4 days, recurrent infections (>2 in 6 weeks), visible tube blockage (white debris inside lumen)	ENT exam + microsuction cleaning; avoid cotton swabs
6–18 months	Tubes fully functional; gradual reduction in infections; possible early extrusion (one side first)	No extrusion by 18 months (short-term), persistent otorrhea, hearing dip on home sound-check (e.g., missing soft speech)	Audiogram + otoscopy; discuss long-term tube options if indicated
18–36 months	Most short-term tubes extruded; eardrum healing; occasional fluid may recur but resolves faster	Tubes still in at 24+ months with no signs of loosening; new hearing loss; persistent perforation >3 months post-extrusion	ENT evaluation for manual removal or tympanoplasty consult if perforation persists

Frequently Asked Questions

Do ear tubes need to be removed manually — or do they always fall out on their own?

Short-term tubes almost always extrude spontaneously — the eardrum’s natural growth pushes them outward into the ear canal, where they’re either dislodged during cleaning or dissolve harmlessly. Manual removal is rare and only considered if a tube remains in place beyond 3 years *and* causes complications (e.g., persistent otorrhea, granulation tissue, or perforation). Long-term tubes (like T-tubes) have a higher likelihood of requiring removal — about 30% per AAO-HNS registry data — but even then, it’s a quick, in-office procedure using micro-instruments under topical anesthesia. Importantly: Never attempt home removal. That risks eardrum injury or infection.

Can my child swim or get their ears wet with tubes in?

Yes — but with smart precautions. Modern guidelines (per 2021 AAO-HNS Clinical Consensus) state surface swimming (in chlorinated pools or oceans) is safe without earplugs for most children. However, submerging deeply (diving, underwater swimming) or swimming in untreated water (lakes, rivers, hot tubs) increases infection risk. We recommend custom-molded earplugs for kids who dive frequently or have recurrent otorrhea. Also, avoid forcing water into the ear with sprayers or hair rinses — use a damp cloth instead. If drainage occurs after swimming, contact your ENT: It may indicate early infection, not just water exposure.

Will my child need tubes again — and does having them once mean they’ll always need them?

About 20–30% of children require a second set of tubes — typically because underlying risk factors persist (e.g., ongoing daycare attendance, untreated allergies, or craniofacial differences). But recurrence isn’t inevitable. A landmark 2020 longitudinal study in JAMA Pediatrics followed 892 children for 5 years post-tubes and found 68% had no further tube placements and only 1–2 mild infections/year after extrusion. Key protective factors? Early allergy evaluation (42% of recurrent cases had undiagnosed allergic rhinitis), consistent nasal saline irrigation, and avoiding secondhand smoke. So while tubes address the symptom, optimizing the environment addresses the cause.

What happens to the hole in the eardrum after the tube falls out?

In over 95% of cases, the eardrum heals completely within 2–6 weeks — leaving no lasting impact on hearing. The tiny opening (typically 0.8–1.2 mm) closes via epithelial migration and connective tissue repair. Rarely (<5%), a small, stable perforation remains — but unless it’s associated with hearing loss or recurrent infections, it requires no treatment. As Dr. Ramirez notes, 'Think of it like a paper cut on your finger: It leaves a scar, but it doesn’t stop you from typing. Same with the eardrum — minor scarring or a tiny persistent hole rarely affects function.' Audiograms post-healing consistently show normal thresholds across all frequencies.

Are there alternatives to tubes — and do they work as well?

For children with mild, infrequent ear infections, watchful waiting + high-dose amoxicillin remains first-line per AAP. But for chronic cases (≥3 infections in 6 months or ≥4 in 12 months), tubes are the only intervention proven to reduce infection frequency by 45–55% and improve hearing by 10–15 dB — according to Cochrane Review meta-analyses. Alternatives like autoinflation (Otovent devices), probiotics, or chiropractic adjustments lack robust evidence. Nasal steroids help only if allergic rhinitis is confirmed. So while non-surgical options exist, tubes remain the gold standard for medically indicated cases — precisely because their duration is matched to the child’s developmental timeline.

Common Myths About Ear Tube Duration

Myth #1: “If tubes haven’t fallen out by 12 months, something’s wrong.”
False. While 12 months is the *average* for short-term tubes, extrusion timing varies widely. A 2022 AAO-HNS audit found 22% of children retained short-term tubes beyond 18 months with no complications — especially those placed before age 2. The key metric isn’t the calendar — it’s function: Are infections controlled? Is hearing stable? Is there drainage? Absent red flags, extended retention is often biologically appropriate.

Myth #2: “Tubes cause hearing loss or damage the eardrum permanently.”
Unfounded. Decades of longitudinal data show no increased risk of permanent hearing loss from tubes. In fact, they *prevent* conductive hearing loss caused by chronic fluid buildup — which, if left untreated, can delay speech development. Scarring (tympanosclerosis) occurs in ~15% of cases but is almost always asymptomatic and non-progressive. As the AAP states: 'The benefits of improved hearing, reduced infections, and enhanced quality of life far outweigh theoretical long-term risks.'

Your Next Step: Partner With Your ENT — Not Just Wait and Wonder

Knowing how long do tubes stay in kids ears isn’t about memorizing a number — it’s about understanding your child’s unique physiology, recognizing meaningful milestones (not calendar dates), and knowing when to seek expert input. Tubes are a tool, not a deadline. The most empowered parents we work with don’t track months — they track outcomes: fewer ER visits, clearer speech, better sleep, and confident participation in school or play. So if your child’s tubes are still in place past 18 months, don’t panic — but do schedule their next ENT checkup. Bring a 30-second voice memo of them repeating simple words ('ball,' 'shoe,' 'cookie') to assess hearing at home, and note any patterns: Does drainage spike after soccer practice? Does congestion precede every infection? That real-world data is worth more than any timeline chart. Because ultimately, the goal isn’t just tube removal — it’s raising a child whose ears, and confidence, thrive long after the last tube is gone.
