Ruptured Eardrums And Their Impact On Hearing
A perforated eardrum, also called a ruptured eardrum, comes about when a hole or tear develops in the eardrum. The eardrum is the part in the ear that vibrates when it comes into contact with waves of sound. Eardrum injuries are often extremely painful and, in some instances, can lead to infections or hearing loss. Fortunately, most injuries of this type will heal in a couple weeks with no ensuing problems. When an eardrum does not heal naturally, then a surgery may be required to restore normal hearing.
The eardrum structure
The eardrum, or the tympanic membrane, is a cone-shaped and thin piece of tissue that divides the middle and outer ear. It is located at the end of the canal of the ear, or the section that typically builds up wax. The hearing process starts when the visible part of the ear, or the pinna, channels sound waves inside the ear canal. These waves then hit the eardrum, causing it to vibrate.
The production of sound
Within the inner ear, these same vibrations turn into nerve impulses, all of which are converted by the cochlea. The impulses then continue to travel to the brain along the auditory nerve . The auditory cortex in the brain receives the signals, then translates them into varying sounds.

Has Anyone Ever Died From Ear Surgery
However, the blood supply to the vital brain centers may be disturbed in the removal of the tumor and some other procedure. If this occurs, serious complications result, including loss of muscle control, stroke, paralysis, or death. In our experience, death occurs rarely, even in the largest and most complicated cases.
How Are Perforated Eardrums Treated
Usually, a perforated eardrum will heal on its own within a few weeks. While the eardrum is healing, your doctor might suggest:
- taking over-the-counter pain relievers
- using antibiotics to prevent infections or treat any existing infections
While your eardrum heals:
- Donât use over-the-counter ear drops unless your doctor tells you to. If there is a hole in the eardrum, some kinds of ear drops can get into the middle ear or cochlea and cause problems.
- Avoid getting water inside the ear canal. Your doctor might recommend that you keep your ear dry during water activities to prevent infection. Gently place a waterproof earplug or cotton ball coated with petroleum jelly in your ear when you shower or take a bath.
- Donât clean your ear or forcefully blow your nose. Wait until the tear in your eardrum is completely healed.
If your eardrum doesnât heal on its own, an ear-nose-throat specialist may recommend surgery to place an eardrum patch. The doctor puts a paper patch over the hole after applying a special medicine to make the tear heal. Doctors may need to do this procedure a few times until the eardrum is fully healed.
If the eardrum patch doesnât work, the ENT specialist might do a surgery known as a tympanoplasty. The surgeon will attach a small patch of your own tissue or use man-made material to cover the hole in your eardrum.

What Causes A Perforated Eardrum
A perforated eardrum is a rupture or tear in the tympanic membrane, located between your outer ear and middle ear. It can be caused by an infection leading to the accumulation of fluids or in the middle or inner ear. The ear may continue to swell and the eardrum may burst upon experiencing pressure.
Sudden, dramatic shifts in air pressure, such as those experienced when flying in an airplane or scuba diving, can cause your eardrum to burst. This is known as barotrauma and occurs from extreme pressure differences between the inside of your ear and the outside. Loud noises, such as from jackhammers and construction, fireworks, gunshots, or loud music, can cause a perforated eardrum. Sticking foreign objects in your ear can also rupture the eardrum.

How Long Does Hearing Loss Last After A Ruptured Eardrum
Most people in the United States enjoy what might be described as the priceless gift of good hearing. However, more than 200,000 people each year experience a ruptured eardrum . That is usually a temporary condition, but it can also have serious and long-lasting consequences if not treated quickly and properly.
A ruptured eardrum is simply a perforation, or a tear, in the thin skin-like tympanic membrane that separates ones outer ear from the delicate structures of the middle and inner areas. It senses vibrating sound waves and passes the vibrations through the bones of the middle ear. Because these vibrations allow a person to hear, ones hearing will suffer if the eardrum is damaged. It is also a protective device, shielding the inner area from the potential damage of bacteria, water, and foreign objects.
Who Is Affected By Nihl
Exposure to harmful noise can happen at any age. People of all ages, including children, teens, young adults, and older people, can develop NIHL. Based on a 2011-2012 CDC study involving hearing tests and interviews with participants, at least 10 million adults in the U.S. under age 70and perhaps as many as 40 million adults have features of their hearing test that suggest hearing loss in one or both ears from exposure to loud noise. Researchers have also estimated that as many as 17 percent of teens have features of their hearing test suggestive of NIHL in one or both ears , based on data from 2005-2006.

Head Injuries & Hearing Loss
In the United States alone, estimates suggest that there are over one million cases of traumatic brain injury each year which require hospitalization, and as many as 3 million cases of any head injury, including mild concussions. Survivors of serious head injuries may suffer permanent, lifelong effects, and those whose injuries are more mild may experience negative side effects that last days, weeks, or longer. Hearing loss, either temporary or permanent, is one of those side effects. So how exactly do head injuries affect the sense of hearing?
What Are The Causes Of A Ruptured Eardrum
- Ear infection within the middle ear
- Injury to the side of the head as a result of a sudden and forceful strike to the head
- Sticking objects in the ear that travel too far down in the ear canal and can puncture the eardrum, such as a cotton swab or bobby pin
- Sudden change in air pressure
- Loud noise caused by an explosion

Fluid Drainage From The Ear
A ruptured eardrum may be accompanied by bleeding or fluid drainage from the ear. The fluid may appear clear, tinged with blood, or contain pus. This effect generally occurs when an ear infection has caused the rupture, or the fluid may indicate an injury in the deeper recesses of the ear. Doctors may take a sample of the fluid draining from the patient’s ear to determine if an infection is causing the ear problem and what type of pathogen it is so the appropriate treatment can begin. Although bleeding or fluid drainage from the ear may be upsetting, it does not generally mean a serious problem has occurred inside the ear canal.

Whistling Sound When Blowing Nose
A ruptured eardrum may cause a whistling sound when the patient blows their nose. In general, blowing the nose with a ruptured eardrum is not recommended. Doing so increases the pressure inside the ear, which can be very painful. It may slow down the rate at which the rupture heals, ultimately delaying recovery. Instead of blowing the nose, doctors suggest that patients with a ruptured eardrum clear their nose by exhaling gently through one nostril at a time to prevent alterations of the pressure inside the ears. Patients may wish to consult their physician about other remedies for nasal congestion that are safe to use with a ruptured eardrum. If a whistling sound when blowing the nose occurs, the patient should see an ear, nose, and throat specialist. The specialist can perform an otoscope exam and other tests to check whether the patient’s eardrum is continuing to heal as it should, and they may be able to recommend steps to increase the speed of the patient’s recovery.

How Long Does It Take To Get Hearing Back After Perforated Eardrum
4.1/5hearing lossabout it here
It takes several weeks for a ruptured eardrum to heal. Most people will not lose all of their hearing, however, rarely, hearing loss may occur in the damaged ear. While the ruptured eardrum is healing, you should not go swimming or participate in certain physical activities.
One may also ask, how long does it take for hearing to come back? These symptoms often go away within 16 to 48 hours. In extreme cases, it may take a week or two. Further exposure to extremely loud noises can also trigger the ringing again. Sometimes this hearing loss can develop into tinnitus that lasts more than six months.
Likewise, can you hear with a perforated eardrum?
The vibration continues through the bones of the middle ear. Because this vibration allows you to hear, your hearing can suffer if your eardrum is damaged. A ruptured eardrum is also called a perforated eardrum. In rare cases, this condition can cause permanent hearing loss.
What should you not do with a ruptured eardrum?
Follow these tips to avoid a ruptured eardrum:
What Is A Perforated Eardrum
The eardrum is a thin membrane that separates your ear canal from your middle ear. The eardrum, also called the tympanic membrane, is involved in hearing. Sound waves cause your eardrum to vibrate. This begins the process of converting the sound waves into an impulse that travels to your brain, where it is recognized as sound.
The eardrum is delicate and can be torn easily, most often by an infection of the middle ear but also by other types of trauma, including:
- Inserting an object, such as a cotton swab or toothpick, too far into the ear
- A very loud noise, such as an explosion
- Trauma to the head, such as a skull fracture
- A blow to the ear
- Trauma to the ear caused by changes in air pressure , such as during a plane flight or scuba diving

No Treatment Is Needed In Most Cases
A torn eardrum will usually heal by itself within 6-8 weeks. It is a skin-like structure and, like skin that is cut, it will usually heal. In some cases, a doctor may prescribe antibiotic medicines if there is an infection or risk of infection developing in the middle ear whilst the eardrum is healing.
It is best to avoid water getting into the ear whilst it is healing. For example, your doctor may advise that you put some cotton wool or similar material into your outer ear whilst showering or washing your hair. It is best not to swim until the eardrum has healed.
Causes Of A Perforated Ear Drum
The most likely cause of a perforation is an earinfection. During an ear infectionfluid builds up in the outer and middle ear which then puts pressureon the ear drum. As more and more fluid appears this stresses the eardrum to the extent that it rips or splits.
A lesser known cause is that of a foreignbody. Children especially enjoy exploring areas of their body whichusually involves the insertion of an object or two. The most popularplaces for this are the nose and ears. So if you are a parent of a youngchild then dont be surprised if you find a small toy or householdobject in there!This isnt usually a problem as they either remove this object themselvesor the object in question makes its own way out.
But in a few cases the object has beenpushed that far down into the ear that it requires medical interventionto remove it.
This is discussed in more detail inour foreignbody in the ear section.This can happen with adults as well. A common scenario is that wheresomeone uses a cotton wool bud or a hair pin to clean out wax from theirear but this then forces the wax deeper into the ear. Or the excessiveforce punctures the ear drum.
Exposure to extremely loud noises suchas an explosion can also damage the ear drum. But this tends to be rare.

To Tube Or Not To Tube
Traditionally, children who experience recurrent ear infections for three months or longer and have hearing loss are candidates for a myringotomy, a surgery in which tubes are inserted into the ear to keep the middle ear ventilated. However, in light of new studies, doctors are increasingly opting to forgo this surgery. A 1994 study found that in 23 percent of cases, tubes were medically unnecessary. In addition, a new study of 182 children, published in a recent issue of the medical journal Lancet, found that putting off surgery for up to nine months didnt hamper a toddlers long-term language abilities. If your doctor suggests a myringotomy, you might want a second opinion.

What Research Is Being Done On Nihl
The National Institute on Deafness and Other Communication Disorders supports research on the causes, diagnosis, treatment, and prevention of hearing loss. NIDCD-supported researchers have helped to identify some of the many genes important for hair-cell development and function and are using this knowledge to explore new treatments for hearing loss.
Researchers are also looking at the protective properties of supporting cells in the inner ear, which appear to be capable of lessening the damage to sensory hair cells upon exposure to noise.
The NIDCD sponsorsIt’s a Noisy Planet. Protect Their Hearing®, a national public education campaign to increase awareness among parents of preteens about the causes and prevention of NIHL. Armed with this information, parents, teachers, school nurses, and other adults can encourage children to adopt healthy hearing habits.

What To Do If You Think You Have A Perforated Eardrum
If you think you may have a perforated eardrum, see your doctor for advice. Although most perforations heal on their own over time, sometimes treatment is needed.
Keep your ear dry. Its very important to keep your ear dry if the eardrum membrane has been ruptured, because any water that gets inside the ear could lead to infection. To help with this, wear earplugs or a shower cap to cover your ears when showering, and avoid swimming.
You should also protect your eardrum by avoiding blowing your nose or cleaning inside your ear.
How Can Noise Damage Our Hearing
To understand how loud noises can damage our hearing, we have to understand how we hear. Hearing depends on a series of events that change sound waves in the air into electrical signals. Our auditory nerve then carries these signals to the brain through a complex series of steps.
