A perforated eardrum typically announces itself with a sudden, sharp ear pain that fades quickly, followed by muffled hearing and sometimes fluid draining from the ear. You may notice all of these signs or just one or two, depending on the size of the tear and what caused it. Here’s how to recognize what’s happening and what to expect if your eardrum does have a hole.
The Key Signs of a Perforated Eardrum
The most telling symptoms tend to arrive together or in quick succession:
- A sudden, sharp pain that may fade within minutes or hours. Many people describe a “pop” sensation right before the pain hits, especially if the rupture was caused by pressure changes or an impact.
- Muffled hearing or sudden hearing loss in the affected ear. Sounds don’t disappear entirely, but they can seem distant or dulled, as if you’re hearing through a wall.
- Fluid draining from the ear. This can range from clear and watery to thick and yellowish or greenish. It may contain blood, especially right after the rupture. Some drainage has a foul smell, while other types are odorless.
- Ringing, buzzing, or humming (tinnitus) that seems to come from inside your ear rather than from any outside source.
Not every perforation causes noticeable drainage. Small tears sometimes produce only mild hearing changes and a brief episode of pain that resolves so fast you might second-guess whether anything happened. Larger perforations are harder to miss because the hearing loss is more obvious and drainage is more likely.
What Causes an Eardrum to Rupture
The most common cause is a middle ear infection. Fluid and pressure build up behind the eardrum until it gives way, which actually relieves the pain of the infection even as it creates a new problem. If you’ve had several days of worsening ear pain from an infection and then suddenly feel better while noticing fluid leaking from your ear, that sequence strongly suggests a perforation.
Pressure changes are the next most frequent culprit. Flying in an airplane, scuba diving, or even a forceful sneeze can create a pressure difference between the middle ear and the outside environment that the eardrum can’t handle. This is called barotrauma, and the rupture usually happens during rapid altitude or depth changes.
Direct trauma rounds out the list: a cotton swab pushed too deep, a slap to the side of the head, or exposure to a very loud blast or explosion. Any of these can tear the eardrum instantly.
How a Doctor Confirms It
You can’t see your own eardrum, so a confirmed diagnosis requires a professional exam. A doctor will look into your ear canal with a lighted scope called an otoscope, which gives a direct view of the eardrum’s surface. A hole, tear, or area of thinning is usually visible on inspection.
If the diagnosis isn’t clear from a visual check, two additional tests help. Tympanometry measures how well the eardrum moves when a small puff of pressurized air is directed into the ear canal. A perforated eardrum won’t move normally, producing a distinctive flat reading. A hearing test (audiometry) can quantify how much hearing you’ve lost and whether the loss is the conductive type, meaning sound isn’t being transmitted mechanically through the middle ear the way it should be.
In cases where a growth called a cholesteatoma is suspected, a CT scan may be ordered to get a detailed look at the structures behind the eardrum.
What Happens During Healing
Most small perforations heal on their own within three to six weeks without any surgical intervention. Larger tears or those complicated by infection can take several months. During this time, the eardrum tissue gradually closes the gap from the edges inward, similar to how skin heals over a wound.
The most important thing you can do while healing is keep water out of the ear. Water entering through the perforation reaches the middle ear directly and can introduce bacteria, leading to infection. Use a cotton ball coated in petroleum jelly as a plug when showering, and avoid swimming or submerging your head until a doctor confirms the eardrum has closed. Resist the urge to clean inside the ear canal with swabs or any other object.
Hearing typically improves as the eardrum heals. If your hearing doesn’t return to normal after several weeks, or if drainage from the ear persists, those are signs the perforation hasn’t closed on its own.
When Surgery Becomes Necessary
A perforation that won’t heal on its own may need a surgical repair called a tympanoplasty. During this procedure, a small piece of tissue (often taken from nearby) is used to patch the hole. The success rate is high: 75% to 90% of eardrum holes are successfully repaired with surgery, according to Johns Hopkins Medicine. Persistent hearing loss and ongoing ear drainage are the main signs that point a doctor toward recommending the procedure.
Complications Worth Knowing About
Most perforations heal cleanly, but a hole that stays open for a long time creates an ongoing path for bacteria to reach the middle ear. Repeated or chronic infections can lead to a cholesteatoma, an abnormal growth made of skin cells and debris that forms in the middle ear. Cholesteatomas grow slowly but can erode the tiny bones responsible for hearing, causing progressive hearing loss.
In rare cases, a chronic middle ear infection can spread to the mastoid bone (the bony bump you can feel behind your ear), causing a serious infection called mastoiditis. Even rarer but more severe complications include infections that spread to the inner ear, resulting in dizziness and a type of permanent hearing loss, or infections that reach the brain. These outcomes are uncommon, especially when a perforation is identified and managed early.
How to Tell It Apart From Other Ear Problems
Ear pain with no drainage and no sudden hearing change is more likely an outer ear infection (swimmer’s ear) or a middle ear infection that hasn’t ruptured yet. Swimmer’s ear tends to hurt more when you tug on your earlobe or press on the small flap in front of the ear canal, which isn’t typical of a perforation.
If you have gradual hearing loss without pain, wax buildup or age-related hearing changes are more probable. The hallmark of a perforation is the combination: sudden onset, a sharp pain that resolves relatively quickly, and at least some change in hearing or the appearance of drainage. When those pieces line up, a perforated eardrum is the most likely explanation.
