A ruptured eardrum happens when the thin membrane separating your ear canal from your middle ear tears or develops a hole. The most common causes are ear infections, sudden pressure changes, physical trauma, and exposure to extremely loud blasts. Most perforations heal on their own within a few weeks, though larger tears can take months and sometimes require surgery.
Ear Infections
Middle ear infections are the leading cause of ruptured eardrums, especially in children. When bacteria or viruses infect the middle ear, fluid and pus build up in the small space behind the eardrum. That pressure pushes outward against the membrane, and if the infection is severe enough, the eardrum gives way. You might actually feel a sudden relief of pain when this happens, because the pressure that was causing the ache has been released.
Repeated ear infections can weaken the eardrum over time, making it more vulnerable to future ruptures even from mild infections. People who had chronic ear infections as children sometimes carry thin or scarred eardrums into adulthood.
Pressure Changes (Barotrauma)
Your eardrum works best when the air pressure on both sides is equal. When that balance shifts dramatically, the membrane can stretch beyond its limit and tear. This is called barotrauma, and it’s the second most common cause of rupture.
Situations that create dangerous pressure differences include:
- Scuba diving, particularly during rapid ascent or descent
- Flying, especially during takeoff and landing with a cold or sinus congestion
- Driving at high altitude through rapid elevation changes
- A direct blow to the ear, such as a slap or airbag deployment, which compresses air in the canal
If your Eustachian tubes (the small channels connecting your middle ear to the back of your throat) are blocked by congestion, allergies, or swelling, they can’t equalize pressure the way they normally would. That makes barotrauma much more likely during activities that would otherwise be fine.
Blast Waves and Loud Noise
Explosions and other intense sound events can rupture an eardrum through the sheer force of the pressure wave. Research from the Defense Technical Information Center estimates that a fast-rising blast overpressure of about 5 psi is enough to rupture some human eardrums, while roughly 15 psi will rupture about half of all exposed eardrums. At pressures between 6 and 70 psi, rupture becomes increasingly likely. This is relevant for military personnel, people near industrial explosions, and anyone exposed to sudden, intense blasts. Gunfire at close range, fireworks mishaps, and even powerful car stereo systems at extreme volumes can generate enough force to cause a tear.
Physical Objects and Trauma
Inserting anything into the ear canal carries a risk of puncturing the eardrum. Cotton swabs are one of the most common culprits, but bobby pins, pen caps, and other small objects can do the same damage. Children sometimes rupture their eardrums by pushing toys or small objects into their ears.
Head injuries, particularly skull fractures involving the temporal bone (the bone surrounding your ear), can also tear or shatter the eardrum. In these cases the perforation is part of a more serious injury.
How a Ruptured Eardrum Feels
Some people feel a sharp, sudden pain that fades quickly. Others notice no pain at all, especially if the rupture was caused by a slow-building infection. The most telling signs tend to come after the tear has already happened: a sense of fullness or muffled hearing in the affected ear, ringing or buzzing, and drainage. The fluid coming from the ear can be clear and watery, thick and pus-filled, or bloody, depending on the cause. Bloody or pus-filled drainage after ear pain is a strong signal that the eardrum has perforated.
Hearing loss from a ruptured eardrum is usually mild to moderate and temporary, though it depends on the size and location of the tear. Some people also experience brief dizziness or a spinning sensation, because the inner ear’s balance system sits just beyond the eardrum and can be temporarily affected.
How Healing Works
Most ruptured eardrums heal on their own without any procedure. Small tears typically close within a few weeks, while larger perforations can take a few months. During that time, keeping the ear dry is essential. Water entering through a perforation can introduce bacteria directly into the middle ear and cause infection, so covering the ear while showering or bathing is standard advice.
Your doctor may prescribe antibiotic ear drops if the rupture was caused by infection or if there are signs of bacterial contamination. Otherwise, the main treatment is watchful waiting: periodic checks to confirm the membrane is closing properly and hearing is returning.
When Surgery Is Needed
If a perforation hasn’t closed after conservative care, including dry ear precautions and topical drops, surgical repair becomes an option. The procedure, called tympanoplasty, patches the hole using a small piece of your own tissue, usually taken from nearby. A meta-analysis of tympanoplasty outcomes found an average success rate of 87%, with rates in individual studies ranging from 35% to 98% depending on perforation size, location, and the overall health of the middle ear.
The American Academy of Otolaryngology recommends surgical repair in several specific situations: when the small bones of the middle ear have been disrupted or damaged, when chronic or recurring ear infections keep the perforation from healing, when hearing loss persists after three months of conservative treatment, or when the perforation makes it impossible to safely bathe or swim without risking infection.
Potential Complications
Most ruptured eardrums heal cleanly, but there are a few things to watch for. Repeated infections through an open perforation can lead to chronic middle ear disease, where the ear stays inflamed and drains on and off for months. Persistent perforation also leaves your middle ear exposed to bacteria every time water gets in.
A rarer but more serious complication is cholesteatoma, a growth that forms when skin cells from the ear canal migrate through the perforation and become trapped in the middle ear space. These growths expand slowly and can erode the tiny bones responsible for hearing, potentially causing permanent hearing loss. Cholesteatomas don’t resolve on their own and require surgical removal. They can develop after perforations caused by infection, trauma, or previous ear surgery, which is one reason doctors monitor unhealed perforations closely rather than simply waiting indefinitely.
