What's a Perforated Eardrum?
Turn that music down or you'll burst your eardrums!
Has anyone ever said that to you? You might have wondered if you really can burst an eardrum. Well, maybe not from playing the music too loud, but there are other causes.
The most common reason is an ear infection. Pus builds up behind the eardrum, also called the tympanic membrane, and it causes a tear.
Usually, the person feels a sharp pain, fluid drains out of the ear canal, and the person has some hearing loss, which is usually temporary. In some cases, a doctor may need to apply a patch or do surgery to repair the tear. But more often, the tear heals by itself and the person's hearing returns to normal in a few weeks.
The Eardrum "Ruptures" or "Perforates"
A hole in the eardrum is also called a ruptured or perforated eardrum. Something that has ruptured has broken. And perforation means a hole or holes. Maybe you've used perforated paper. It's the kind in a spiral notebook that tears out easily because of the holes along the left side.
To understand a torn eardrum, you first need to know how the ear works and what the eardrum is. It's sort of like a drum because it's a thin piece of skin-like tissue stretched tight across the opening between your outer ear canal and the middle ear.
Your outer ear funnels sound waves into your ear canal, where they hit your eardrum and make it vibrate. Your middle ear and inner ear convert the vibrations to signals that your brain interprets as sounds.
If there is a hole in the eardrum, it might not vibrate very well, which can make your hearing worse. Most people with a perforated eardrum get all their hearing back eventually.
A perforated eardrum also can allow bacteria to enter your middle ear. This can lead to an infection that can cause more hearing loss.
What Causes a Perforated Eardrum?
In addition to ear infections, you can tear your eardrum by poking something in your ear, even a cotton swab. They're really not needed to keep your ears clean.
Here are some other causes:
- Air pressure changes: When the air pressure changes, it can make your ears "pop." This is normal and often happens when flying in a plane or driving high into the mountains. But if the air pressure changes all of a sudden, it can cause a tear in the eardrum.
- Very loud noises, such as an explosion
- Head injuries that cause a fractured skull bone or a direct blow to the ear (like a slap)
