A ruptured eardrum is almost never permanent. Most perforations heal on their own within a few weeks to two months, and those that don’t can usually be repaired with surgery that succeeds 75% to 90% of the time. The real question isn’t whether it can heal, but what affects whether yours will.
How Most Ruptured Eardrums Heal
The eardrum is a thin membrane, but it has a reliable blood supply and regenerates well. Small tears from sudden pressure changes, ear infections, or minor trauma typically close without any medical intervention. You may notice muffled hearing and some discomfort for a few days to a few weeks, but once the membrane seals itself, hearing usually returns to normal.
The timeline depends mostly on the size of the hole. A small perforation (roughly the size of a pinhead) can close in a couple of weeks. Medium and larger tears take longer, sometimes up to two months. If the eardrum hasn’t healed within three to six months, the perforation is considered chronic, and it’s unlikely to close on its own from that point.
What Hearing Loss Feels Like
While the hole is open, sound waves can’t vibrate the eardrum as efficiently, so hearing drops. How much depends on the size of the perforation. A small hole reduces hearing by roughly 9 decibels, which is subtle enough that you might only notice it in quiet environments. A medium-sized hole causes about 16 decibels of loss, noticeable in everyday conversation. A large perforation can mean around 26 decibels of loss, roughly the difference between normal hearing and mild hearing impairment.
This type of hearing loss is mechanical, not nerve damage. The inner ear still works fine. That’s why repairing the membrane almost always restores hearing.
Factors That Prevent Healing
Several things can keep an eardrum from closing on its own. The most common is ongoing infection. If bacteria keep reaching the middle ear through the hole, inflammation prevents the edges of the tear from knitting together. Chronic ear infections are the leading reason perforations become long-term problems.
Water exposure is another major factor. Getting water in an ear with an open perforation introduces bacteria directly into the middle ear, which can restart infection and delay healing. During recovery, you should use waterproof earplugs or a cotton ball coated with petroleum jelly when showering or bathing. Swimming and diving are off limits until the eardrum has fully closed.
A few other things to avoid while healing:
- Cleaning inside the ear. Even gentle use of cotton swabs can disturb the healing tissue.
- Blowing your nose forcefully. This pushes air and mucus through the Eustachian tube and can put pressure on the fragile membrane.
- Over-the-counter ear drops. Unless specifically prescribed, liquid in the ear canal can reach the middle ear and cause irritation or infection.
Poor Eustachian tube function also plays a role. The Eustachian tube equalizes pressure between the middle ear and the outside world. If it doesn’t work well, because of allergies, sinus problems, or anatomical differences, the middle ear stays under negative pressure, which pulls on the eardrum and can prevent a hole from sealing.
When a Perforation Becomes Chronic
If your eardrum hasn’t healed after three to six months, it’s considered a chronic perforation. At that point, the edges of the hole have typically scarred over, and the body has stopped trying to close the gap. This doesn’t mean you’re stuck with it permanently, but it does mean the membrane won’t repair itself without help.
Living with a chronic perforation carries real risks beyond hearing loss. The open hole gives bacteria a direct path to the middle ear, making recurring infections more likely. Over time, a more serious complication can develop: dead skin cells that normally shed outward from the ear canal can instead grow inward through the hole and accumulate behind the eardrum, forming a cyst-like growth called a cholesteatoma. Left untreated, a cholesteatoma can damage the tiny bones of the middle ear, potentially causing more significant hearing loss and, in rare cases, affecting the facial nerve.
Repair Options for Non-Healing Perforations
Two main procedures can fix a chronic hole in the eardrum, and both have strong track records.
Myringoplasty
This is the simpler option. A surgeon patches the hole using gel foam, surgical paper, or a similar synthetic material. It can sometimes be done in an office under local anesthesia, though many people have it performed in a hospital under general anesthesia. The success rate is around 90%, with some studies reporting up to 94%. It’s typically recommended when the perforation hasn’t healed within three months, when ear infections keep recurring, or when hearing loss from the hole is affecting daily life.
Tympanoplasty
For larger holes or cases where there’s damage to the tiny bones behind the eardrum, tympanoplasty is the standard approach. The surgeon uses a graft, often taken from tissue near the ear, to rebuild the membrane. Success rates range from 75% to 90%, depending on the condition of the eardrum, whether infection is present, and whether prior ear surgery has been performed. Recovery takes a few days to several weeks, though full healing of the eardrum and improvement in hearing can take two months or longer. In rare cases where the first surgery doesn’t fully resolve the problem, a second procedure may be needed.
What Long-Term Outlook Looks Like
For the vast majority of people, a ruptured eardrum is a temporary problem. Small holes heal without intervention. Larger or chronic perforations are fixable with procedures that succeed roughly nine times out of ten. Because the hearing loss from a perforation is mechanical rather than nerve-based, restoring the membrane’s integrity restores hearing in most cases.
The perforations that do become permanent are almost always ones complicated by untreated chronic infection, repeated trauma to the same ear, or conditions that keep the Eustachian tube from functioning properly. Even in those cases, surgical repair remains an option. A truly irreparable eardrum is exceptionally rare.
