Most ruptured eardrums are not a medical emergency and heal on their own within a few weeks to a couple of months. That said, a perforation does carry real risks if it’s ignored, particularly chronic infection, lasting hearing loss, or the growth of a cyst behind the eardrum that can cause further damage. The seriousness depends largely on the size of the tear, what caused it, and how well you protect the ear while it heals.
What a Ruptured Eardrum Feels Like
The first sign is usually a sharp ear pain that fades quickly, sometimes within minutes. After the initial pain passes, you may notice fluid draining from the ear. This can be clear mucus, bloody, or pus-filled if an infection is involved. Hearing in that ear will likely feel muffled or reduced. Some people also experience ringing (tinnitus), dizziness, or nausea, especially if the rupture was sudden or caused by a pressure change.
These symptoms can range from barely noticeable to quite disruptive. A small pinhole tear from a cotton swab might cause mild discomfort and slight hearing changes, while a larger rupture from a blast of pressure can bring intense vertigo that lasts hours.
Common Causes
Ear infections are the most frequent culprit. When fluid and pressure build up behind the eardrum, the membrane can burst to relieve that pressure. Once the infection is treated, these perforations typically close on their own.
Trauma is the other major category. Cotton swabs pushed too far into the ear canal are a classic cause. Sudden pressure changes, known as barotrauma, can also do it. This happens during airplane descent, scuba diving, or even a hard slap to the side of the head. Extremely loud sounds, like an explosion at close range, can rupture the membrane as well.
How Much Hearing Loss to Expect
A ruptured eardrum causes a type of hearing loss called conductive loss, meaning sound waves can’t travel as efficiently to the inner ear. The degree depends on the size of the hole. Research shows perforations cause hearing loss in the range of 10 to 40 decibels. To put that in perspective, 10 decibels of loss is barely perceptible, like the difference between a quiet room and a very quiet room. At 40 decibels of loss, normal conversation becomes difficult to follow without straining.
The hearing loss is more noticeable with lower-pitched sounds and proportional to how much of the eardrum is torn. The good news is that once the perforation closes, hearing typically returns to normal or near-normal levels.
When It Heals on Its Own
Most perforations heal spontaneously. Small tears from cotton swabs or minor infections often close within a few weeks. Larger perforations can take up to two months. During this time, the edges of the hole gradually regenerate tissue and seal shut without any medical intervention beyond keeping the ear clean and dry.
Your doctor will likely check the ear periodically to confirm it’s closing. If a perforation hasn’t healed after several weeks of proper care, or if it keeps getting infected, surgical options come into play.
Protecting Your Ear While It Heals
Water is the biggest threat during recovery. Even small amounts of water entering the ear canal can introduce bacteria through the hole and cause infection. Don’t swim until a doctor confirms the eardrum has fully closed. When showering or bathing, place a waterproof silicone earplug or a cotton ball coated with petroleum jelly in the outer ear to create a seal.
A few other precautions make a real difference:
- Don’t clean your ears. Leave the ear canal alone and let the membrane heal undisturbed.
- Avoid blowing your nose forcefully. The pressure travels up the tube connecting your nose to your middle ear and can push against the healing membrane.
- Skip ear drops unless a doctor specifically prescribes them for an associated infection. Over-the-counter drops can irritate or damage the exposed middle ear.
When Surgery Is Needed
Perforations that persist despite dry ear care and initial treatment are candidates for surgical repair. The procedure is called tympanoplasty, and there are several approaches depending on the situation. The simplest is an in-office patch, where a doctor freshens the edges of the hole and places a small paper patch over it to guide tissue growth. This is quick but has the lowest success rate for larger tears.
A more effective office option uses a tiny plug of fat taken from the earlobe under local anesthesia to seal the perforation. For larger or more complex tears, a formal tympanoplasty in an operating room uses tissue grafts to reconstruct the membrane. Recovery from surgery generally takes a few weeks, during which you’ll follow the same water precautions as with a naturally healing perforation.
Surgery is most strongly considered when a perforation causes both ongoing hearing loss and repeated drainage or infection.
Complications That Make It Serious
The perforation itself is rarely dangerous, but leaving it untreated long-term opens the door to problems that are. Chronic ear infections are the most common complication. With a hole in the eardrum, bacteria have a direct path into the middle ear, and repeated infections can damage the tiny bones responsible for transmitting sound.
A more concerning complication is a cholesteatoma, a cyst-like growth that forms when dead skin cells collect behind the eardrum. Chronic infections and ruptured eardrums can both trigger this growth. A cholesteatoma starts small but expands over time. Without treatment, it can erode the bones of the middle ear, cause permanent hearing loss, and in rare cases damage the facial nerve. Cholesteatomas require surgical removal.
These complications are preventable. Getting the ear checked after a rupture, keeping it dry, treating any infection promptly, and following up if the hole isn’t closing are the straightforward steps that keep a routine perforation from becoming something more serious.
