An ear infection in a child with tubes looks different from a regular ear infection. Instead of a bulging, red eardrum hidden behind an intact membrane, the telltale sign is drainage coming out of the ear. This discharge, called otorrhea, is the most visible and often the only obvious symptom. Because the tube provides an open pathway from the middle ear to the ear canal, infected fluid drains outward rather than building up behind the eardrum.
What the Drainage Looks Like
The fluid you’ll see on your child’s outer ear, pillow, or around the tube opening can vary quite a bit depending on the type and stage of infection. In the early hours, it may be thin, clear, or slightly cloudy. As the infection progresses, the drainage typically turns yellow or green and becomes thicker, sometimes with a consistency similar to mucus. Pus-like discharge, often yellowish-green and opaque, is the most common sign of a bacterial infection in the tube.
Occasionally you may notice a small streak of blood mixed in, especially if the ear canal is irritated. A foul smell is another important clue. Not all drainage smells, but when it does, it usually signals a more active bacterial infection. The drainage can range from a small amount that dries around the ear opening to enough to visibly wet the outer ear or leave stains on bedding.
Why It Looks Different From a Regular Ear Infection
In a child without tubes, an ear infection traps fluid and pus behind an intact eardrum. The pressure builds, causing intense pain, and the eardrum often looks red and bulging when a doctor examines it. You can’t see any of this from the outside unless the eardrum ruptures on its own.
Tubes change the equation entirely. They sit in a small opening in the eardrum and act as a pressure release valve, keeping air flowing into the middle ear and allowing fluid to drain out. Because infected fluid has an exit path, the pressure that causes severe pain in a typical ear infection often never builds up. That’s why an ear infection with tubes can sometimes be “quieter” than you’d expect. Your child may have visible drainage but seem relatively comfortable, or at least far less distressed than during previous infections before the tubes were placed.
Symptoms Beyond the Drainage
Drainage is the headline symptom, but it’s not always the only one. About two-thirds of children with ear infections develop a low-grade fever. With tubes in place, the infection may be otherwise mild enough that fever is the only additional sign, or there may be no fever at all.
Younger children who can’t describe what they feel may tug or pull at the affected ear, become irritable, sleep poorly, or refuse food. Some children experience temporary changes in hearing if the drainage is thick enough to partially block the tube. In many cases, though, the infection with tubes is simply less symptomatic overall. An episode of otorrhea through a tube can be “otherwise asymptomatic and less troublesome than ear infection episodes in children with intact eardrums,” as a review from the Agency for Healthcare Research and Quality put it. That said, some episodes do come with noticeable pain, foul odor, and fever.
When the Ear Canal Itself Looks Abnormal
If you’re able to peek into your child’s ear (or a doctor does), the skin of the ear canal may appear pink, swollen, or wet from the drainage. In some cases, you might see a small crust of dried discharge around the tube itself.
Less commonly, a fleshy, reddish growth called granulation tissue can develop around the tube. This looks like a small, raised, bumpy area near the tube opening. It’s an inflammatory response to the tube rather than an infection itself, but it can trap moisture and make infections more likely. Granulation tissue sometimes bleeds easily when touched. If you notice persistent redness, a visible lump near the tube, or bloody drainage that doesn’t seem tied to a cold or obvious infection, that’s worth bringing up with your child’s ear doctor.
How Tube Infections Are Treated
The standard treatment for an uncomplicated tube infection is antibiotic ear drops, not oral antibiotics. Clinical practice guidelines strongly recommend topical drops alone for most cases. The drops deliver medication directly to the infection site at concentrations far higher than what an oral antibiotic could achieve in the ear, while barely reaching the bloodstream. The drops also typically contain a small amount of anti-inflammatory medication to help calm the swelling.
The bacteria most commonly responsible for these infections include the same ones behind standard ear infections, plus one waterborne species (Pseudomonas) that can enter through the tube during baths or swimming. The prescription drops are designed to cover all of these.
Most parents notice the drainage starting to improve within the first few days of drops. If drainage continues beyond 7 to 10 days without improvement despite treatment, that’s a signal to follow up with your child’s doctor. Persistent or recurring drainage can sometimes point to a blocked tube, resistant bacteria, or the granulation tissue described above.
What to Watch For Day to Day
Once you know what tube drainage looks like, it becomes easier to spot an infection early. A small amount of clear fluid right after tube placement is normal and not a sign of infection. What you’re watching for is new drainage that appears days, weeks, or months later, especially if it’s cloudy, colored, thick, or smelly.
Keep the outer ear clean by gently wiping away visible drainage with a soft cloth. Avoid pushing anything into the ear canal. If your child’s doctor has prescribed drops for you to keep on hand, starting them promptly when you see the first signs of drainage can shorten the episode. The key advantage of tubes is that infections become easier to see and easier to treat, even if the sight of fluid draining from your child’s ear feels alarming the first time it happens.
