Ear tube surgery is one of the safest and most common pediatric procedures performed today. Serious complications are rare, the operation itself takes about 10 to 15 minutes, and most children are back to normal activities the same day or the next. That said, no surgery is completely without risk, and understanding what those risks actually look like can help you feel confident in the decision.
What the Procedure Involves
During ear tube surgery (formally called tympanostomy tube insertion), a surgeon makes a tiny incision in the eardrum and places a small tube to allow air into the middle ear and fluid to drain out. The procedure is done under general anesthesia in children, though some clinics now offer in-office placement for select patients to avoid anesthesia altogether. The surgery is brief, typically wrapping up in under 15 minutes, and is performed on an outpatient basis, meaning you go home the same day.
Common Complications and How Often They Happen
The most frequent issue after ear tube surgery is ear drainage, called otorrhea. This is fluid or mucus leaking from the ear through the tube, which is actually the tube doing its job. It can happen shortly after surgery or occasionally later, and it’s usually treated with antibiotic ear drops.
A persistent hole in the eardrum after the tube falls out is the complication most parents worry about. This happens in roughly 1 to 5% of cases and occasionally requires a second, separate surgery to repair. However, some audits of tube patients have found perforation rates as low as zero percent after tube removal or natural extrusion, suggesting that for most children, the eardrum heals on its own without issue.
Scarring on the eardrum, known as tympanosclerosis, is common after tubes but is almost always harmless. Studies show it causes less than half a decibel of hearing change, which is clinically insignificant. You or your child would never notice it.
Anesthesia Risks in Children
Because ear tube surgery is so quick, the anesthesia exposure is among the shortest of any surgical procedure. The risks of general anesthesia are generally low in healthy children, though possible reactions include nausea and, less commonly, breathing difficulties or heart rhythm changes.
One thing that catches many parents off guard is emergence delirium. Up to 50% of children experience a period of confusion, crying, or agitation for up to 30 minutes after waking from anesthesia. It can look alarming, but it resolves on its own and has no lasting effects. Knowing this ahead of time makes the recovery room much less stressful.
How Effective Ear Tubes Are
A systematic review of 41 studies found that ear tubes decrease middle ear fluid and improve hearing in the short term compared to watchful waiting. For children who have been struggling with muffled hearing for months, this relief can be significant and fairly immediate.
The longer-term picture is more nuanced. The same review found that tubes may not make a measurable difference in hearing outcomes over one to two years, likely because many children’s ear problems resolve naturally over that timeframe regardless of treatment. The real value of tubes is in those months of better hearing and fewer infections during a critical window for speech and language development, rather than changing the trajectory years down the road.
When Tubes Are Recommended
Doctors don’t recommend tubes for every child who gets ear infections. Clinical guidelines from the American Academy of Otolaryngology set specific thresholds. Tubes are recommended for children with fluid in both ears lasting three months or longer when there’s documented hearing difficulty. They’re also recommended for children with recurrent ear infections who still have fluid present at the time they’re being evaluated for tubes.
Tubes are not recommended for a single episode of ear fluid lasting less than three months, or for children with recurrent infections who don’t have any fluid in their ears at the time of evaluation. For children with balance problems, behavioral issues, poor school performance, or ear discomfort tied to persistent fluid, tubes may be offered even outside the standard criteria.
Will Your Child Need a Second Set?
Most ear tubes stay in place for 6 to 18 months before the eardrum naturally pushes them out. Some children’s ear problems return after that, and they need another set. The likelihood depends on age and the severity of the underlying problem. Children under four tend to have higher rates of needing additional tubes.
For children who end up needing a third set, having the adenoids removed at the same time significantly reduces the odds of further procedures. In one study of children under four, 44% of those who received tubes alone went on to need a third set, compared to just 13% of those who had tubes plus adenoid removal.
Recovery and Water Precautions
Recovery from ear tube surgery is fast. Most children experience little to no pain, and many return to daycare or school the next day. Your surgeon will likely prescribe antibiotic ear drops for a short period after the procedure.
The water restriction question is one of the biggest surprises for parents. Current clinical guidelines from 2022 state that routine water precautions, including earplugs, headbands, and avoiding swimming, are not necessary for children with ear tubes. The recommended approach is to allow unrestricted water activity first and only introduce precautions if problems arise. Exceptions include children who develop recurrent drainage, those with immune conditions, and situations involving heavily contaminated water or deep diving. Surface swimming in treated pools is considered safe for the vast majority of children with tubes in place.
