An ear infection in a child with tubes looks different from a typical ear infection. Instead of the usual signs like intense ear pain, fever, and fussiness, the primary symptom is visible drainage leaking from the ear canal. This is because the tube provides an opening in the eardrum, so infected fluid drains outward rather than building up behind it. That drainage is the key thing to watch for and know how to read.
What the Drainage Looks Like
The hallmark of a tube-related ear infection (called otorrhea) is fluid coming out of your child’s ear. It can range from thin and watery to thick and mucus-like. The color is what tells you the most: yellow, green, or cloudy white drainage signals infection. It may also have a noticeable odor. In some cases the fluid is brownish or tinged with blood, especially if the infection has been going on for several days.
This is very different from normal earwax, which is typically amber or orange-brown, waxy in texture, and doesn’t have a strong smell. Infectious drainage tends to be wetter, messier, and may leave stains on your child’s pillow or collar. If you’re unsure whether what you’re seeing is wax buildup around the tube or actual drainage, the consistency is usually the giveaway. Wax is sticky and thick. Infected fluid is more liquid and keeps coming.
How Symptoms Differ From a Regular Ear Infection
Without tubes, a middle ear infection traps fluid behind the eardrum. That pressure causes significant pain, often accompanied by fever, trouble sleeping, and in younger children, pulling at the ear and crying. The eardrum itself bulges and reddens, though parents can’t see that without a special instrument.
With tubes, the experience is usually much milder. Because the tube lets fluid escape, there’s typically little to no pain. Your child might not act sick at all. You may simply notice wetness in or around the ear. Fever is less common with uncomplicated tube infections, though it can still occur. The tradeoff is clear: less suffering for your child, but the infection can be easier to miss if you’re not checking the ears regularly.
Why Infections Still Happen With Tubes
Tubes reduce the frequency of ear infections, but they don’t eliminate them entirely. The tube itself creates a small open channel between the outside world and the middle ear. Bacteria that normally live in the ear canal, including types like Pseudomonas and Staph that wouldn’t typically cause a standard ear infection, can travel inward through the tube. This is why water precautions are sometimes recommended, and why infections with tubes can involve different germs than the ones that cause regular childhood ear infections.
Infections can also happen when your child catches a cold. The same bacteria responsible for typical ear infections (common respiratory bacteria) can still reach the middle ear through the Eustachian tube from the back of the throat. When that happens, the fluid drains out through the ear tube rather than getting trapped, which is actually the tube doing its job.
What to Do When You See Drainage
Antibiotic ear drops are the standard treatment for uncomplicated tube infections. Clinical guidelines strongly recommend topical drops rather than oral antibiotics for this situation. The drops go directly to the site of infection and work faster. In one study comparing ear drops to oral antibiotics, children using drops saw drainage stop in a median of 4 days compared to 7 days for those taking oral medication. The cure rate was also substantially higher: 85% for drops versus 59% for oral antibiotics.
After starting drops, some drainage in the first few days is expected and normal. Five to seven days of drops is usually enough. If drainage hasn’t decreased within five days or isn’t completely gone within a week, that’s the point to contact your child’s doctor. Persistent drainage may mean the infection involves resistant bacteria, or that something else is going on with the tube itself.
Signs That Need Prompt Attention
Most tube infections are straightforward and resolve with drops, but certain signs warrant a call to your child’s ENT specialist. Yellow, brown, or bloody discharge lasting more than a week is one. Drainage with a foul smell, especially if accompanied by fever and pain, can indicate a more serious infection. And if your child suddenly starts complaining of ear pain or pressure after a period of the tubes working well, the tube may be clogged or may have fallen out.
Clogged or Displaced Tubes
Tubes can become clogged with dried drainage, earwax, or thickened mucus. When that happens, the tube stops functioning and your child essentially loses the benefit of having it. Fluid builds up behind the eardrum again, and symptoms start to resemble a regular ear infection: pain, pressure, muffled hearing, and irritability. Clogging can happen right after placement, after an infection episode, or as the tube naturally works its way out.
Most tubes are designed to stay in place for about a year before the eardrum gradually pushes them out. This is a normal process called extrusion. Sometimes tubes fall out without anyone noticing, and the only clue is that infections start presenting the old way again, with pain and pressure instead of drainage. If the eardrum doesn’t fully heal after a tube comes out, the small remaining hole can become a pathway for recurring infections. Your child’s scheduled follow-up visits are designed to catch these changes early.
What Normal Looks Like After Tube Surgery
Some drainage in the first few days after tube placement is completely normal. This fluid may be bloody or contain mucus, and it simply represents the fluid that was already trapped behind the eardrum finally escaping. This post-surgical drainage usually clears up within a few days with the drops prescribed at the time of surgery.
Once the ears settle, a healthy tube sits quietly in the eardrum and is essentially invisible from the outside. You won’t see it without a special scope. The ear canal should look dry and clean between infections. Any new onset of wetness, fluid, or discharge after that initial healing period is worth noting and likely represents a new infection that needs treatment.
