A busted (perforated) eardrum looks like a hole or tear in a thin, translucent membrane deep inside the ear canal. You won’t see it by looking in a mirror. The eardrum sits about an inch inside the ear canal, so the perforation itself is only visible with a special lighted scope called an otoscope. What you can see without any tools are the signs that something has gone wrong: fluid draining from the ear, sometimes tinged with blood, and in some cases a noticeable drop in hearing on that side.
What the Eardrum Normally Looks Like
A healthy eardrum is a small, oval, slightly cone-shaped membrane about the size of a dime. When a doctor looks at it through an otoscope, it appears pearly gray or light pink and slightly translucent. You can sometimes see the faint shadow of the tiny bones behind it. The surface has a subtle light reflex, a small bright triangle of reflected light that tells clinicians the membrane is smooth and properly positioned.
What a Perforation Looks Like Through a Scope
When the eardrum is ruptured, the most obvious feature is a dark hole or slit in that pearly membrane. The hole can range from a tiny pinpoint to a large opening that takes up most of the drum’s surface. The edges of the tear may appear ragged or irregular, especially if it was caused by a sharp object or sudden pressure change. In some cases, the remaining membrane around the hole looks red, swollen, or inflamed.
Where the hole sits on the drum matters. A perforation in the lower, stretched portion of the membrane (the largest area) is the most common type. Holes near the back edge of the drum tend to cause more hearing loss because of their position relative to the inner ear structures. Holes near the front that have lost their surrounding rim of membrane are harder for the body to heal on its own. Small perforations left behind after ear tubes fall out are usually tiny and often have minimal impact on hearing.
A doctor examining a perforated eardrum will note the hole’s size and location, check for signs of infection, look for any debris or skin buildup around the edges, and assess whether the small bones of the middle ear (visible through the hole) appear intact or disrupted.
What You Can See Without a Scope
Since you can’t see the eardrum itself without medical equipment, the visible clues of a rupture are all about what comes out of the ear. The most common sign is fluid drainage. This can look different depending on what caused the rupture.
- Infection-related rupture: The drainage typically looks like mucus or yellow-green pus. It may have some blood mixed in and can smell bad. If you see this kind of discharge from your ear or your child’s ear, it almost always means a middle ear infection has built up enough pressure to burst through the drum.
- Trauma or pressure-related rupture: You may see blood-tinged or clear fluid. This happens after a blow to the head, a sudden pressure change (like diving or a nearby explosion), or an object pushed into the ear canal. The drainage tends to be thinner and less discolored than what you see with infection.
In both cases, the drainage often brings a strange sense of relief. If an ear infection caused the rupture, the pain that had been building frequently eases once the pressure releases through the hole.
Other Symptoms That Accompany a Rupture
Beyond visible drainage, a busted eardrum typically causes a sudden sharp pain at the moment it tears, followed by a dull ache or no pain at all. Hearing on that side drops noticeably, though how much depends on the size and location of the hole. You may also hear ringing or buzzing (tinnitus) in the affected ear.
If the rupture was caused by a pressure injury or trauma, dizziness and nausea can occur because the inner ear’s balance system sits just beyond the eardrum. Dizziness, nausea, and vomiting after an ear injury are considered emergency symptoms and warrant immediate medical evaluation, as they can signal damage beyond the membrane itself.
How It Heals
Most ruptured eardrums heal on their own without treatment. The membrane regenerates from its edges inward, gradually closing the hole over a period of weeks. Some perforations take a few months. During healing, it’s important to keep water out of the ear, since moisture reaching the middle ear through the hole can cause infection and slow recovery.
About 80% of traumatic perforations close on their own. The ones that don’t heal tend to be larger, located in spots with poor blood supply, or complicated by ongoing infection. Chronic or repeated ear infections lasting more than 12 weeks can prevent the membrane from repairing itself, leading to a persistent hole. When a perforation hasn’t closed after several months, or when ongoing infection keeps it from healing, surgical repair becomes an option. The procedure patches the hole using a small piece of tissue, usually taken from nearby.
When Location Changes the Outcome
Not all perforations behave the same way. A small hole in the center of the drum may cause only mild hearing loss and heal quickly. A perforation along the back edge of the drum, sitting over the round window (a key structure connecting to the inner ear), causes greater hearing loss relative to its size. Holes near the front edge that lack a surrounding rim of intact membrane heal less reliably because new tissue has no scaffold to grow across.
Your doctor will track the perforation’s progress over follow-up visits using an otoscope, watching for the edges to gradually close inward. If healing stalls, or if hearing loss is significant, they’ll discuss whether repair makes sense for your situation.
