A perforated eardrum is a hole or tear in the thin membrane that separates your ear canal from your middle ear. This membrane, called the tympanic membrane, vibrates when sound waves hit it, which is the first step in how you hear. When it’s perforated, sound doesn’t transmit as effectively, and the normally protected space behind it becomes exposed to bacteria, water, and debris. Most perforations heal on their own within a few weeks to a couple of months, but larger tears sometimes need medical help to close.
What the Eardrum Actually Does
Your eardrum is a small, oval disc of connective tissue about the size of a dime. It has three layers: an outer skin-like layer, a flexible middle layer containing nerves and blood vessels, and an inner layer made of the same moist tissue that lines parts of your digestive tract. This layered design makes it both sensitive enough to pick up faint sounds and sturdy enough to act as a barrier, keeping dirt, bacteria, and other material out of the delicate middle ear space behind it.
When sound waves travel down your ear canal, they cause the eardrum to vibrate. Those vibrations pass through three tiny bones in your middle ear and eventually reach the inner ear, where they’re converted into nerve signals your brain interprets as sound. A hole in the membrane disrupts that chain, which is why hearing loss is one of the most common symptoms of a perforation.
Common Causes
The most frequent cause is a middle ear infection. When fluid builds up behind the eardrum, the pressure can make it tear or pop. This is especially common in children, who get ear infections more often than adults.
Pressure changes, known as barotrauma, are another major cause. If air gets trapped in your middle ear during a flight or while scuba diving, a sudden shift in pressure can rupture the membrane. A hard blow to the side of the head, including from a car airbag, can produce the same effect.
Less common causes include:
- Loud blasts or explosions. Gunfire or nearby explosions can generate enough force to tear the eardrum.
- Objects in the ear. Cotton swabs, hairpins, or other small items can puncture the membrane if pushed too deep.
- Severe head trauma. A skull base fracture can damage the middle and inner ear structures, including the eardrum.
What a Perforation Feels Like
A sudden perforation often causes a sharp pain that fades relatively quickly. You may notice a temporary buzzing or ringing in the affected ear, along with a sense that your hearing has gone dull or muffled on that side. If the perforation was caused by an infection, you might see pus or bloody fluid draining from the ear. That drainage can actually bring some pain relief, because it means the pressure behind the eardrum has been released.
Some people also experience dizziness or a spinning sensation right after the membrane tears, especially if cold air or water enters the middle ear through the new opening. This usually settles down within hours. Small perforations sometimes cause almost no noticeable symptoms at all, and people only discover them during a routine ear exam.
How It’s Diagnosed
A doctor can usually spot a perforation just by looking into your ear canal with a lighted scope called an otoscope. The hole or tear in the membrane is often visible directly. If there’s fluid draining from the ear, a sample may be sent to a lab to check for bacterial infection.
To assess how much the perforation is affecting your hearing, you may get a tuning fork test or a more detailed hearing evaluation called audiometry, which measures your hearing at different volumes and pitches. Another test, tympanometry, checks how well the eardrum responds to pressure changes. Together, these help determine whether the hearing loss is coming from the perforation itself or from deeper damage in the inner ear.
Healing and Recovery Timeline
Most perforations close on their own without any surgical intervention. Small holes typically heal within a few weeks. Larger tears can take up to two months. During this time, the edges of the tear gradually grow inward until the membrane seals itself.
While you’re healing, keeping water out of the ear is critical. Water entering the middle ear through the hole can introduce bacteria and cause an infection that slows healing or makes things worse. Use a cotton ball coated in petroleum jelly as an earplug when showering, and avoid swimming or submerging your head until a doctor confirms the membrane has closed.
One important precaution: certain ear drops can be harmful when the eardrum isn’t intact. Drops containing specific antibiotics in the aminoglycoside family (commonly found in some over-the-counter ear preparations) can potentially damage the delicate structures of the inner ear if they pass through the perforation. Always let your doctor or pharmacist know about the perforation before using any ear drops.
When Surgery Is Needed
If a perforation doesn’t close on its own after a couple of months, or if it’s large enough that natural healing is unlikely, a procedure can help.
The simplest option is a paper patch myringoplasty. A doctor places a small piece of special paper or gel foam over the hole to act as a scaffold, encouraging the body’s own healing processes to seal the gap. Sometimes a tiny piece of fat tissue taken from the earlobe is used as the patch instead. This works best for relatively small perforations.
For larger holes, a procedure called tympanoplasty is more common. The surgeon uses a graft of your own tissue, typically connective tissue taken from just beneath the skin near the ear. This graft is slipped behind or on top of the hole and held in place with a small amount of dissolvable packing material that breaks down over two to three months as the eardrum heals around it. Recovery from tympanoplasty generally means a few weeks of restricted activity and keeping the ear dry, with gradual improvement in hearing as the graft integrates.
Risks of Leaving It Untreated
A perforation that stays open long-term leaves the middle ear permanently exposed. This creates an ongoing risk of repeated infections, since bacteria and water can freely enter the space. Chronic or recurring middle ear infections can damage the tiny bones responsible for transmitting sound, leading to more significant and potentially permanent hearing loss.
In rare cases, skin cells from the ear canal can grow through the perforation into the middle ear, forming a noncancerous but destructive growth called a cholesteatoma. This growth slowly expands, eroding nearby bone and tissue. Left unchecked, it can damage the bones of the middle ear, spread infection to the surrounding skull bone (a condition called mastoiditis), and in the most serious cases affect the inner ear or nearby structures. Cholesteatomas require surgical removal.
Small perforations that remain stable, with no infections and minimal hearing impact, are sometimes monitored rather than surgically repaired. The decision depends on the size, location, and whether the opening is causing recurring problems. A perforation near the center of the eardrum, for example, tends to cause less hearing loss than one near the edges where the membrane connects to the ear canal wall.
