Ear tubes, also called tympanostomy tubes or PE tubes (pressure equalization tubes), are tiny cylinders placed through the eardrum to create an air passage between the middle ear and the outside world. The procedure is common in children who get frequent ear infections, and it usually takes about 15 minutes under general anesthesia. The main benefit is a sharp drop in ear infections and improved hearing for most children. The risks are generally low but include infection, drainage, and the tube getting stuck or falling out too early.
What Are PE Tubes and How Do They Work?
PE tubes are small, hollow cylinders usually made of plastic or metal. A surgeon makes a tiny cut in the eardrum, removes any fluid, and places the tube in the opening. The tube stays in place for 6 to 18 months on average. During that time it keeps the middle ear ventilated.
This ventilation does two things. First, it prevents fluid from building up behind the eardrum. Second, it equalizes pressure between the ear canal and the middle ear. Without this balance, children get painful ear infections more often. The tube acts like a permanent drain and air vent combined.
What Are the Main Benefits of PE Tubes?
The most well-documented benefit is a large reduction in ear infections. The CDC reports that about 5 out of 6 children will have at least one ear infection by age three. For children who get repeat infections — three or more in six months — tubes are the standard treatment. Studies published in Pediatrics show that children with tubes have about 50% fewer ear infections in the first year compared to those treated with antibiotics alone.
Hearing improvement is another major benefit. Fluid behind the eardrum can muffle sound by 15 to 40 decibels. That is like putting a hand over your ear. Once the fluid drains through the tube, hearing usually returns to normal within days. This matters for speech development in young children. Research from the American Academy of Otolaryngology links chronic fluid in the ears with delayed language skills.
Quality of life also improves. Fewer infections means fewer trips to the doctor, less missed school, and less missed work for parents. One study in the International Journal of Pediatric Otorhinolaryngology found that parents reported a 70% drop in their child’s ear-related distress after tube placement.
What Are the Risks and Side Effects of PE Tubes?
No surgery is risk-free, and PE tubes have known complications. The most common issue is otorrhea — drainage from the ear. This happens in about 15% to 20% of children at some point while the tube is in place. Most cases clear up with antibiotic ear drops and do not require tube removal.
Other risks include:
- Blockage: The tube can get clogged with dried fluid or blood. This happens in about 7% of cases and sometimes requires replacement.
- Early extrusion: The tube falls out before it should. This occurs in roughly 10% of children and may mean the child needs another procedure.
- Persistent perforation: After the tube falls out, the hole in the eardrum does not close. This happens in about 2% to 4% of cases and may need surgical repair.
- Scarring: The eardrum can develop a small scar. This rarely affects hearing but is visible on exam.
Serious complications like permanent hearing loss or damage to the inner ear are extremely rare. When they happen, they are usually linked to an underlying ear condition rather than the tube itself.
How Does the Procedure Work and What Is Recovery Like?
The procedure is done under general anesthesia. The child is asleep and feels nothing. The surgeon uses a microscope to see the eardrum clearly. A small incision is made, fluid is suctioned out, and the tube is inserted. The whole thing takes about 15 minutes. Most children go home within an hour or two.
Recovery is fast. Many children are back to normal activities the next day. Doctors usually recommend keeping water out of the ears while the tubes are in place. This means using earplugs or a swim cap during baths and swimming. Some children need antibiotic ear drops for a few days after surgery.
Follow-up visits happen at 2 to 4 weeks after surgery and then every 6 months until the tubes fall out. The doctor checks that the tube is in the right place and that the eardrum is healthy. Most tubes fall out on their own within 6 to 18 months. The eardrum hole closes up naturally in almost all children.
What Does Research on PE Tubes Show About Long-Term Outcomes?
Long-term studies are reassuring. A large study in the New England Journal of Medicine followed children with tubes for up to 10 years. It found no difference in hearing, speech, or cognitive development between children who got tubes and those who did not. The main difference was fewer infections and less need for antibiotics in the tube group during early childhood.
Some parents worry that tubes weaken the eardrum permanently. The evidence does not support this. The eardrum heals normally in over 95% of children. For the small number who have a persistent hole, a simple patch procedure closes it in most cases.
There is also no evidence that tubes cause long-term balance problems. Some children have mild dizziness for a day or two after surgery, but it resolves quickly. The inner ear structures that control balance are not disturbed by the tube placement.
How Do PE Tubes Compare to Other Treatments?
For children with frequent ear infections, the main alternatives are watchful waiting and antibiotics. Watchful waiting means treating each infection as it comes with pain relief and monitoring. Antibiotics are used for infections that do not resolve on their own. This approach works well for children who have mild or infrequent infections.
For children with recurrent infections — three or more in six months — tubes are more effective than repeated antibiotics. The table below compares the two approaches.
| Factor | PE Tubes | Antibiotics Alone |
|---|---|---|
| Infection reduction | 50% fewer infections in first year | Each infection treated individually |
| Hearing improvement | Immediate after fluid drains | Depends on infection clearing |
| Procedure needed | One-time surgery | None |
| Side effect risk | Drainage, blockage, scarring | Diarrhea, rash, antibiotic resistance |
| Duration of benefit | 6 to 18 months | Per infection only |
For children with chronic fluid in the ears but no active infections, tubes are the standard treatment if the fluid has been present for more than 3 months and hearing is affected. The American Academy of Otolaryngology recommends tubes in this situation because hearing loss from fluid can delay speech.
Common Misconceptions About PE Tubes
One common myth is that tubes are only for children with severe infections. In reality, tubes are also used for children who have persistent fluid without pain. This condition, called otitis media with effusion, affects hearing even though the child does not seem sick.
Another misconception is that tubes cause hearing loss. The opposite is true. Tubes restore hearing by draining fluid. The tiny hole in the eardrum does not affect hearing ability. The eardrum still vibrates normally because the tube is small and does not interfere with the drum’s movement.
Some parents believe that once tubes fall out, the ear infections will come back. This is not usually the case. Most children grow out of the tendency to get ear infections by age 4 to 6. The Eustachian tube matures and drains more effectively. Tubes simply bridge the gap during the high-risk years.
People also worry that water in the ears will cause serious infections. While it is true that water can enter the middle ear through the tube, the risk of a serious infection is low. Most doctors recommend water precautions as a safety measure, not because the risk is high. A 2021 review in Otolaryngology–Head and Neck Surgery found no strong evidence that swimming without earplugs causes more infections in children with tubes.
Frequently Asked Questions
Is the PE tube procedure painful for a child?
The child is under general anesthesia during the procedure and feels no pain. Some children have mild ear discomfort for a day or two afterward.
How long do PE tubes stay in the ear?
Most tubes fall out on their own within 6 to 18 months. The eardrum hole closes up naturally after the tube is gone.
Can a child swim with PE tubes?
Doctors usually recommend earplugs for swimming to keep water out. Surface swimming is generally fine with precautions, but diving or deep water should be avoided.
What happens if a PE tube does not fall out on its own?
If the tube stays in longer than 2 to 3 years, an ear doctor can remove it in a simple office visit. The eardrum usually heals on its own after removal.
