Grommets (Ear Tubes): What They Are, What They Do and Whether They Fall Out

Type the word grommets into a search bar and the first page is a small comedy of errors: brass rings for curtains, rubber gaskets for boat covers, eyelets for tarpaulins. Somewhere below all that hardware sits the thing a worried parent was actually looking for after a conversation with an ear specialist about a four-year-old who keeps saying pardon.

The two meanings are not as far apart as they look. In both cases a grommet is a reinforced ring that holds a hole open. The difference is that the medical version is roughly the size of a grain of rice, sits in a membrane thinner than paper, and is designed to leave on its own once its work is done.

This piece is for anyone weighing the ear kind. It covers why doctors suggest them, what the procedure feels like from a family’s side, what the evidence says about risks, and the question almost everyone asks in the recovery room: so when does it come out?

What are grommets, exactly?

A grommet is a small tube, usually made of plastic or metal, that a surgeon places through a tiny incision in the eardrum. In the United States the same device is more often called an ear tube, a tympanostomy tube or a ventilation tube. The names are interchangeable; the job is the same.

That job is ventilation. The middle ear is a sealed, air-filled chamber behind the eardrum, and it stays healthy only when air pressure inside matches the pressure outside. Normally the Eustachian tube, a narrow passage running from the middle ear to the back of the nose, does this balancing. When it fails and fluid builds up, a grommet acts as a stand-in vent. Air gets in, fluid gets out, and the eardrum can move freely again so sound reaches the inner ear.

Mayo Clinic describes the tubes as typically small enough to be placed in a procedure lasting about 15 minutes, and notes that most are designed to fall out by themselves as the eardrum heals around them. That self-limiting design is the central idea: grommets buy time while a child’s Eustachian tubes mature, rather than fixing them permanently.

Cleveland Clinic describes ear tube placement as one of the most common childhood operations performed under anesthesia. Common is not the same as trivial, though, and the rest of this article treats the decision with the seriousness families bring to it.

Why would someone need grommets?

Two situations account for almost every grommet placed. The first is glue ear, the everyday name for otitis media with effusion: sticky fluid trapped behind the eardrum without an active infection. The second is recurrent acute ear infections, the painful, feverish kind, coming back again and again despite treatment.

The NHS notes that glue ear usually clears on its own within about three months. That single figure shapes how clinicians think. Fluid that lingers well beyond that window, particularly in both ears and particularly when it is dulling hearing, is the classic reason a specialist starts talking about tubes. Mayo Clinic similarly lists fluid in both ears for more than three months with hearing loss as a common reason for the operation.

Repeated infections are the other path. Each episode of acute otitis media brings pain, disturbed sleep and often a course of antibiotics. When infections keep returning, a grommet changes the physics: fluid that would have pooled behind the eardrum and become infected now drains outward instead. Mayo Clinic notes this is why frequent infections are a recognized indication.

Less often, grommets are used for a persistently retracted eardrum, for pressure problems that are not settling, or in adults whose Eustachian tube function has been damaged. The common thread in every case is a middle ear that cannot ventilate itself and needs a temporary helping hand.

What is glue ear, and why does it hit children so often?

Picture a young child’s Eustachian tube as a short, nearly horizontal drinking straw. An adult’s is longer, wider and angled steeply downward, so gravity helps it drain. The child’s version is easily blocked by a cold, by swollen adenoids at the back of the nose, or by allergy-related inflammation. Once blocked, the middle ear cannot equalize pressure, the lining secretes fluid, and that fluid has nowhere to go.

Over weeks the fluid thickens into something with the consistency of syrup or glue, which is where the name comes from. It is not usually infected and often does not hurt, which is precisely why it slips under the radar. The child is not crying; the child is just a bit vague.

The NHS notes glue ear is common in young children and that many cases follow a cold or ear infection. Children in group childcare, children exposed to tobacco smoke at home, and children with conditions such as Down syndrome or cleft palate are more prone to it, according to the same source, because their Eustachian tubes are more often blocked or work less efficiently.

The reassuring part of this anatomy lesson is that time is on the child’s side. Eustachian tubes lengthen and steepen with growth, which is why glue ear becomes progressively less common through the school years. A grommet is a bridge across the years when the plumbing is least reliable.

How do I know my child needs grommets? Signs to watch for

Glue ear rarely announces itself. Parents more often describe a slow drift: the television creeping louder, a child who seems to ignore instructions from another room, a toddler whose words are not arriving on schedule. Teachers sometimes notice first, because a classroom is a noisier and less forgiving listening environment than a kitchen.

The NHS lists these as the signs that matter most:

• Hearing that seems muffled or reduced, often fluctuating from week to week
• Speech or language that is falling behind what is expected for age
• Difficulty following conversation in groups or background noise
• Balance that is a little off, more frequent stumbles or clumsiness
• Tiredness, frustration or behavior changes that seem out of proportion
• Ear pain or a feeling of fullness, particularly during colds

None of these on its own means grommets are needed. Every child mishears sometimes, and every toddler has a clumsy month. What clinicians look for is a pattern that persists past the three-month window the NHS describes and that is confirmed on a hearing test rather than guessed at.

One concrete home observation is worth more than a dozen vague worries: does your child hear a whisper from behind, without seeing your face? Consistent failure to respond to quiet sounds, especially in both ears, is exactly the sort of detail that helps a primary care clinician decide whether a formal hearing assessment and specialist referral are warranted.

What happens before the decision: the three-month rule and hearing tests

Grommets are almost never a first move, and that is by design. The NHS approach to glue ear begins with watchful waiting, because most fluid clears by itself within about three months. A clinician who suggests waiting is not brushing you off; they are following the evidence that a large share of children get better without any intervention.

During that period the ear is checked with an otoscope, sometimes with tympanometry, a painless test that puffs a little air against the eardrum and measures how well it moves. A stiff, unmoving eardrum suggests fluid behind it. A formal hearing test, tailored to the child’s age, establishes how much the fluid is actually costing in decibels.

That measurement is the pivot. Fluid that is present but not affecting hearing is a different problem from fluid that is muffling every classroom instruction. Mayo Clinic frames the common threshold as fluid in both ears for more than three months accompanied by hearing loss, and notes that persistent fluid can affect speech development and behavior if left unaddressed.

Families sometimes feel the wait is wasted time. In practice it is diagnostic. If the fluid clears, the child has been spared an anesthetic. If it does not, the specialist now has a documented history that justifies the operation, and the decision rests on evidence rather than a single snapshot on one bad day.

What does grommet surgery involve?

The operation is called a myringotomy with tube insertion, and it is quicker than most parents expect. Mayo Clinic puts the procedure itself at around 15 minutes. Children have a general anesthetic, usually delivered as a gas through a mask, so there is no needle while they are awake. Adults can often have it done under local anesthetic in a clinic room.

Working through the ear canal with a microscope, the surgeon makes a tiny slit in the eardrum, suctions out the trapped fluid, and slides the grommet into the opening so that its flanges hold it in place. No external cut is made; there are no stitches and no visible scar. If the adenoids are enlarged and thought to be contributing, they are sometimes removed at the same time, a decision the surgical team will discuss beforehand.

Recovery is brisk. MedlinePlus notes that most children go home the same day, typically within an hour or two of waking. Grogginess, irritability and a small amount of drainage from the ear over the first day or two are expected. Many children are back at school or childcare the following day, though the treating team will give specific guidance.

Hearing often improves almost immediately once the fluid is gone, and parents sometimes describe a child who suddenly complains that the house is loud. A follow-up appointment with a hearing test a few weeks later confirms the result and checks the tubes are open.

What are the different types of ear tubes?

The hardware-store analogy holds up here, because grommets come in a few designs chosen for how long they are meant to stay. Mayo Clinic groups them into two broad families.

Type	Design	Typical stay	Usual use
Short-term (standard grommet)	Small, spool-shaped with narrow flanges	Falls out on its own, commonly within 4 to 18 months (Mayo Clinic); NHS gives 6 to 12 months	First-time glue ear or recurrent infections in young children
Long-term (T-tube and similar)	Larger, with wider flanges that anchor it	Designed to remain longer, sometimes years; may need removal	Repeated fluid after earlier tubes, or ongoing Eustachian tube problems

Most children who need grommets receive the short-term version. Its gentle flanges are held only by the tension of the healing eardrum, and as new tissue grows the tube is gradually pushed toward the ear canal until it drops out. The long-term design trades that convenience for staying power; Mayo Clinic notes these tubes may fall out on their own or may need to be removed by the surgeon.

Materials vary too. Fluoroplastic and silicone are common because they resist crusting; some tubes are titanium. Choosing between them is a surgeon’s judgment based on the child’s history, and there is no evidence that any one brand or material is universally superior, which is why this article names none.

Do grommets fall out, and what happens when they do?

Yes, and that is the whole point. A standard grommet is a temporary tenant. The eardrum is living tissue that constantly renews itself from the center outward, and as it heals it slowly extrudes the tube the way skin eventually works out a splinter.

Timelines vary by source and by child. The NHS says grommets usually fall out naturally within about 6 to 12 months. Mayo Clinic gives a wider range, noting that most tubes fall out within 4 to 18 months and that the small hole left behind usually closes on its own. Neither figure is a promise; a tube that lasts nine months in one ear may last fourteen in the other.

Most families never see it happen. The tube is tiny, and it typically works its way into the ear canal where it is either lost in earwax or spotted by a clinician at a follow-up visit. Occasionally a parent finds a speck of blue or white plastic on a pillow. That is not an emergency, and there is nothing to retrieve.

What matters more than the moment of extrusion is what follows. Sometimes the ear stays clear because the child has simply outgrown the problem. Sometimes fluid returns. MedlinePlus notes that a proportion of children need a second set of tubes, which is why specialists usually keep reviewing hearing for a while after the tubes are gone rather than closing the file the day they fall out.

Do grommets need to be removed?

Usually not. Standard grommets are engineered to leave under their own steam, and for most children the story ends there without any second procedure.

There are exceptions, and it helps to know them in advance so they do not come as a shock. Mayo Clinic lists a tube that stays in too long as a recognized complication. If a grommet is still sitting in the eardrum well beyond the expected window, the surgeon may recommend removing it, because a tube that overstays its welcome raises the chance that the hole will not close afterward. Long-term T-tubes, which are designed to stay for years, are more likely to need planned removal than short-term ones.

Removal is a brief procedure, generally simpler than the original placement. In some cases the surgeon will also patch the eardrum at the same time if the opening looks unlikely to heal on its own.

The opposite problem exists too. A tube that falls out very early, within weeks, has not had time to do its job and the fluid may simply return. Mayo Clinic flags early extrusion as a possible complication. The follow-up schedule your specialist sets is not bureaucracy; it is the mechanism for catching both scenarios, the tube that leaves too soon and the one that will not leave at all, while they are still easy to manage.

What are the risks and side effects of grommets?

Grommet surgery is low-risk, but low is not zero, and honest counseling covers the downsides. Mayo Clinic groups the possible problems as follows:

• Bleeding or infection around the time of surgery
• Persistent drainage from the ear, sometimes for weeks
• A tube that becomes blocked with blood, mucus or debris, stopping it from working
• Scarring or thinning of the eardrum, which is often cosmetic but can occasionally affect hearing
• A tube that falls out too early, or one that stays in too long
• A hole in the eardrum that does not close after the tube is gone and may need repair

Ear infections do not disappear entirely after grommets. What changes is their character. Instead of a pressurized, painful middle ear, an infection tends to show up as discharge draining through the tube, often with far less pain. Cleveland Clinic notes these episodes are commonly managed with drops prescribed by the clinician; decisions about which medicine and for how long belong with the prescribing team.

Then there is the anesthetic. Mayo Clinic notes that general anesthesia in otherwise healthy children carries a very low risk of serious complications, and the anesthesia team will review your child’s health beforehand. Concerns about anesthesia are among the most common parents raise, and they deserve a direct conversation rather than reassurance by pamphlet.

Weighing these against the cost of months of muffled hearing during a critical language window is the real decision, and it is one the family and treating team make together.

Can my child swim and bathe with grommets?

The instinct to wrap a grommet-wearing child in waterproof cotton wool is understandable. A grommet is, after all, an open channel from the outside world to the middle ear. The evidence is more relaxed than the instinct.

Mayo Clinic advises that most children with ear tubes do not need earplugs for ordinary swimming in a pool. Surface tension and the tiny bore of the tube mean clean pool water rarely passes through. Where the advice shifts is toward higher-risk water: Mayo Clinic suggests earplugs or a swim cap may be worth considering for lakes, rivers and non-chlorinated water, for deep diving, and for keeping soapy bath water out of the ears, since soap lowers surface tension and lets water slip through more easily.

The NHS takes a similar line for glue ear grommets: swimming is generally fine once the ear has settled after surgery, while avoiding getting soapy or dirty water in the ears. Both sources defer to the individual surgeon, who may have specific instructions based on the type of tube and the child’s history.

A practical middle ground many families settle on is a tilt of the head during hair-washing, a cheap pair of soft earplugs for the bath, and no restrictions at the local pool. If discharge appears after a swim, that is the cue to phone the clinic rather than to abandon swimming lessons.

What are the alternatives to grommets?

Grommets sit at one end of a spectrum of options, and a good specialist will walk through the others rather than presenting surgery as the only door.

Watchful waiting comes first, for the reasons already covered: the NHS notes most glue ear resolves within about three months. During that time hearing is monitored and any contributing factors, such as exposure to smoke, are addressed.

Autoinflation is a curious but evidence-backed technique the NHS describes. The child blows up a special balloon through one nostril several times a day, which forces air up the Eustachian tube and helps the middle ear ventilate. It requires cooperation, so it suits children old enough to follow instructions, and it is not a cure for every case, but it is non-invasive and can be tried while waiting.

Hearing aids are a genuine alternative, not a consolation prize. The NHS lists temporary hearing aids as an option for children with persistent glue ear, particularly where surgery is not suitable or a family would rather avoid it. They do nothing about the fluid but everything about the hearing, which is the thing that actually affects language and learning.

Adenoidectomy, removal of the adenoids, may be combined with grommets or considered separately when enlarged adenoids appear to be blocking the Eustachian tubes. Antibiotics, decongestants and antihistamines are sometimes asked about; the NHS notes they are not recommended as treatments for glue ear itself because the evidence does not support them. The CDC likewise stresses that not every ear infection needs an antibiotic.

Do adults ever need grommets?

Grommets are strongly associated with toddlers, but adult ears run into the same plumbing problems for different reasons. An adult may develop persistent middle ear fluid after a severe cold or sinus infection, after radiation treatment to the head and neck, or because of chronic Eustachian tube dysfunction that leaves the ear feeling permanently blocked, as if descending in an aircraft that never lands.

Frequent flyers and divers with pressure problems that do not respond to simpler measures sometimes have a grommet placed to equalize pressure. In rarer cases a tube is inserted to deliver medication directly to the middle ear for certain inner ear conditions, a decision that belongs entirely with the treating specialist.

The procedure differs mainly in setting. MedlinePlus notes that adults can often have the tube placed under local anesthetic in an office, awake, with the whole visit shorter than a dental filling. Recovery instructions mirror those for children, and the tube extrudes in the same way as the eardrum heals.

One caution applies more to adults than children. Fluid appearing in only one ear in an adult, with no obvious cold or infection to explain it, warrants a proper look at the back of the nose to rule out a blockage there. This is standard practice rather than cause for alarm, and it is a reason not to ignore one-sided fullness that has lasted for weeks.

When to see a doctor about ear symptoms or grommets

Most ear trouble in children is self-limiting, and most grommets behave themselves. A handful of situations deserve a prompt call rather than watchful patience.

Before any decision about grommets, the NHS advises seeing a primary care clinician if a child seems to have hearing difficulties, if speech is delayed, or if hearing problems have lasted more than a few weeks. Ear pain with a high temperature, or symptoms that are not improving after three days, are also reasons to be seen according to NHS guidance on ear infections.

After grommets are in place, seek care promptly if you notice:

• Discharge from the ear that is thick, foul-smelling, blood-stained, or lasts more than a few days
• Ear pain that is severe or getting worse rather than settling
• A fever alongside ear symptoms
• Hearing that has clearly dropped again after initially improving
• Dizziness, a stiff neck, redness or swelling behind the ear, or a child who is unusually drowsy or hard to rouse, which need urgent assessment

Finding the tube itself on a pillow is not one of these. Nor is a small amount of watery drainage in the first couple of days after surgery, which is expected.

The overarching message is proportion. Grommets are a well-understood, short procedure with a strong safety record, and the vast majority of families experience nothing more dramatic than a child who suddenly turns the television down. Knowing the red flags lets you relax about everything else.

Frequently asked questions

Why would someone need grommets?

The two main reasons are persistent glue ear that is affecting hearing and ear infections that keep coming back. Glue ear is fluid trapped behind the eardrum; if it lasts well beyond the three months in which most cases clear, and a hearing test shows it is muffling sound, grommets let the fluid drain and restore ventilation. For recurrent infections, the tube stops fluid pooling where it can become infected.

What are the signs a child might need grommets?

The most telling signs are hearing that seems muffled or inconsistent, speech or language falling behind for age, a child asking for repetition or turning the television up, trouble following conversation in noisy places, and occasional unsteadiness. Ear pain or fullness during colds is common too. None of these confirms the need for grommets; a clinician checks the eardrum and arranges a hearing test before any decision.

Do grommets fall out on their own?

Yes, standard grommets are designed to be pushed out by the healing eardrum. The NHS says this usually happens within about 6 to 12 months; Mayo Clinic gives a broader range of 4 to 18 months. The tube typically ends up in the ear canal and is lost in earwax or spotted at a follow-up visit. The small hole left behind normally closes by itself within weeks.

Do grommets need to be removed?

Usually not. Most short-term grommets leave on their own without any second procedure. Removal is considered when a tube stays in far longer than expected, because an overstaying tube raises the chance the hole will not close, or when a long-term T-tube was deliberately placed to remain for years. Removal is brief and the surgeon may patch the eardrum at the same time if needed.

How do I know my child needs grommets rather than waiting?

The decision rests on time and measurement. Clinicians generally wait about three months because most glue ear resolves in that window. If fluid persists in both ears beyond that point and a hearing test documents a meaningful loss, or if the child is having repeated infections, grommets become a reasonable option. A specialist weighs the hearing result, speech development and family preference together.

Is grommet surgery painful for a child?

The procedure itself is done under a brief general anesthetic, so the child feels nothing during it. Afterwards, mild discomfort, irritability and a little drainage over the first day or two are common, and most children are back to normal activities quickly. Many parents report the ear feels better than before surgery because the pressure from trapped fluid has been released.

Can a child swim with grommets?

In most cases, yes. Mayo Clinic advises that most children with ear tubes do not need earplugs for ordinary pool swimming. Earplugs or a swim cap may be sensible for lakes, rivers, deep diving and for keeping soapy bath water out, since soap lets water pass through the tube more easily. Always follow the specific advice of the surgical team, who know the type of tube used.

What happens if a grommet gets blocked?

A blocked grommet stops ventilating the ear, so fluid and hearing problems can return. Blockage by dried blood, mucus or debris is a recognized complication. Sometimes prescribed drops clear it; sometimes the specialist clears it in clinic, and occasionally the tube needs replacing. A drop in hearing after an initial improvement is the usual clue, and it warrants a follow-up appointment rather than waiting it out.

Will ear infections stop completely after grommets?

Not always, but they typically change character. With a tube in place, an infection tends to drain outward as discharge rather than building painful pressure behind the eardrum, so episodes are usually milder. Persistent or foul-smelling discharge should be assessed by a clinician, who may prescribe drops. The frequency of infections often falls, though the tube does not make the child immune to colds.

What are the alternatives to grommets?

Watchful waiting is the first alternative, since most glue ear clears within about three months. Autoinflation, blowing up a special balloon through the nose, can help ventilate the middle ear in cooperative children. Temporary hearing aids address the hearing loss directly without surgery. Adenoid removal may be considered when enlarged adenoids are blocking the Eustachian tubes. Antibiotics and decongestants are not recommended for glue ear itself.
