If there is a problem in the outer or middle part of the ears, this affects the way sound is carried, or conducted, through to the inner ear and the rest of the auditory system. Hearing loss that results from damage to or disorders of the outer and middle ear is therefore referred to as conductive hearing loss.
The most common cause of conductive hearing loss, which mainly affects children, is otitis media. DiMarco uses the universal language of dance to change the hearing world’s perception of what it means to be Deaf – and he just might win the Mirrorball trophy in the process.
Wearing hearing aids has been such a positive experience for Marie Redfern, she wants to encourage others with hearing loss to try them, too.
Before we examine the implications of this promising development, let's look at what is going on deep inside our ears and what role those miniscule hairs play in our hearing. Unlike the hair that grows on our heads, the hair in our inner ears is not visible to a naked eye, but it has a very important function in our ability to hear. Scientists agree that the key to reversing hearing loss - as well as a wide range of diseases that are currently deemed incurable -lies in human stem cells derived from embryos that have been fertilized in vitro and used for research purposes with consent of the donors. In this country, this issue remains controversial, even though President Obama lifted the longstanding ban on federal funding for embryonic stem cell research. That is just one of several studies carried out in various countries that found that stem cells are instrumental in curing deafness. The latest evidence comes from the Stanford University School of Medicine, where a team of researchers started out with the idea that if they could create hair cells in the laboratory from stem cells, better treatments for deafness and hearing loss would follow.
Stefan Heller, PhD, professor of otolaryngology at the Stanford University School of Medicine and a leader in stem cell-based research on the inner ear, found a way to develop mouse cells that look and act just like the animal's inner-ear hair cells. Eventually, scientists will need human hair cells to experiment on so they can perfect their formula for hair regeneration in the inner ear.
Other studies, conducted over the years by the NIH, also suggest that hair cells could be, contrary to earlier assumptions, regenerated.
An experiment was performed using guinea pigs and gene therapy developed in previous studies. This means that possibly not one, but a combination of therapies, could be used in the future to restore hearing. Admittedly, it is too early to draw any conclusions and it is fair to say that we are still years away from hearing regeneration.
Protecting your hearing takes a conscious effort in focusing on your surroundings and taking steps to protect your hearing from what might be considered as everyday sounds.
Children's hearing is more sensitive because the ear canal is smaller and sounds become louder as they develop in a smaller space.
The outer ear consists of the visible part of the ear (pinna), the ear canal and the ear drum. The middle ear is an air-filled space that contains the three smallest bones in the human body: the malleus, the incus and the stapes.
The vibration of the eardrum moves the three small bones (called ossicles) in the middle ear. Otosclerosis —An abnormal overgrowth of one or more bones in the middle ear prevents the small bones from moving normally.
Meniere's disease — This typically causes dizziness, hearing loss, ringing in the ears (tinnitus) and a sensation of fullness or stuffiness in one or both ears. Drugs — Many prescription and nonprescription medications can damage the ear and cause hearing loss.
If you have sudden, severe hearing loss, you will notice immediately that your ability to hear has decreased dramatically or disappeared totally in the affected ear.
Wear protective earplugs or earmuffs if you are often exposed to loud noise at work or during recreational activities.


Drug-induced hearing loss — Stopping the problem medication may reverse hearing loss or prevent it from getting worse. Sudden sensorineural hearing loss — When the cause is unknown, this condition is usually treated with a corticosteroid, such as prednisone.

The easiest way to lookup drug information, identify pills, check interactions and set up your own personal medication records. However, in cases where medical or surgical intervention is not appropriate, individuals with conductive hearing loss may be managed with hearing aids, including such special devices as bone-anchored hearing aids (BAHA) or bone conductor hearing aids.
So the focus of hearing health professionals and advocates has always been on prevention (avoiding or reducing harmful environmental noises) and treatment (getting fitted with hearing aids). This breakthrough could lead to significant advances to cure deafness and hearing loss in the future. Located in a portion of the ear's cochlea called the organ of Corti, the sensitive hairs are small sensory cells that process and transmit sound to the brain. Over the course of our lives, these hair cells get damaged and die – for example, because of the aging process, toxic drugs, or prolonged exposure to loud environmental noises- causing varying degrees of irreversible hearing loss.
And that's where the new breakthroughs offer glimmers of hope to approximately 33 million Americans currently suffering from hearing loss, and an estimated 500 million worldwide. British scientists discovered a way to turn stem cells into ones that act like hair cells, which could be surgically inserted into the ear to restore hearing.
For example, in the 2007 study called "Hair Cell Regeneration and Hearing Loss," the NIH scientists destroyed hair cells in the inner ear of mice, causing deafness.
Again, the supporting cells migrated, but this time partially restored the hearing, indicating that gene therapy could improve hearing in formerly deaf animals.
However, we are a step closer than we were in the past, and in that sense, this is a positive development. That can translate into as much as a 20 dB difference between an adult's ears and a child's ears which can cause a child's hearing to be damaged more easily.
The cochlea is a snail-shaped bone filled with fluid and thousands of tiny a€?hair cellsa€? that process sound vibrations.
The most common reversible causes are severe buildup of earwax in the ear canal and acute infections of the external ear or middle ear. A vibrating tuning fork is placed in the middle of your forehead to help diagnose one-sided hearing loss. The doctor uses a hand-held device to generate tones of various intensities to find out if you can hear them. Your doctor may recommend a hearing aid or an implant to improve your ability to communicate with others.

In fact, according to the National Institutes for Health (NIH), more than 90 percent of hearing loss is due to destruction of hair cells or auditory nerve cells. In fact, further tests show that mice cells responded to vibrations in a similar way to hair cells in the (human) inner ear. However, the mice's supporting cells spontaneously "migrated to the hair cell region and began growing hair bundles on their surfaces," the researchers reported.
These large pressure waves bend the ear’s hair cells too far, sometimes to the point where they are damaged. The middle ear is also connected to the throat via the Eustachian tube, which makes sure the air pressure is the same on both sides of your eardrum, and allows your ears to a€?popa€? when youa€™re flying in a plane or driving through mountains. Vibrations enter the cochlea and the fluid is set into motion, like a wave, and the hair cells move in response.


Conductive hearing loss is caused by problems with the ear canal, ear drum, or middle ear and its little bones (the malleus, incus, and stapes). The brain is the most important part of hearing since that is where sounds are converted into meaningful information. The vibrations from the ossicles are absorbed into the fluid channels like waves in a pond. Noise-induced hearing loss can happen because of a single brief burst of an extremely loud sound. Acoustic neuroma often causes dizziness and equilibrium problems in addition to gradual hearing loss. Or it can result from a Q-tip that ruptures the eardrum during an attempt to clean the ear canal. Your doctor will want to know if you have been exposed to loud noises, trauma of the ear or head, or ear infections. He or she will check for middle-ear problems by measuring your eardrum's ability to reflect sounds. A hearing aid amplifies sounds electronically and is effective for many people with age-related hearing loss. Although it is usually easily treatable, the incidence of otitis media is significantly higher among Indigenous children, for whom it represents a serious health and educational issue. This kills the hair cell and since cochlear hair cells can’t grow back, this manifests as a permanent hearing loss.
When the hair cells move, they send electrical signals along the hearing nerve and toward the brain.
Sensorineaural hearing loss -- also referred to as nerve-related hearing loss -- is causedby problems of the inner ear.
These bones amplify the vibration and transfer the sound waves to the cochlea in the inner ear. Your doctor will want to rule out the possibility that medications may be causing your hearing loss. Hearing aids today are very small, so small that other people often do not notice you are wearing them. Parents who have concerns about their child's responsiveness to sound, language development, or behaviour should talk to their doctor.
It is typically harder to hear high-pitched tones (women's voices, violins) than low-pitched ones (men's voices, bass guitar). Bending of the hair cells sends electrical impulses to the eighth nerve which carries the signal to the brain. If it can't be corrected withsurgery, then the hearing could be improved with a bone conduction hearing aid, a surgically implanted, osseointegrated device or a hearing aid. However, severe ear infections, chronic middle fluid, and tumors are usually treated with surgery. If there is no response to initial medical therapy, infectious fluid is usually treated with antibiotics -- while chronic non-infectious fluid is treated with surgery.Sensorineural Hearing LossSensorineaural hearing loss from Meniere’s disease may be treated with a low sodium diet, diuretics and corticosteroids. If it can't be treated with these options, then surgical procedures might be an option.Sensorineural hearing loss from tumors are not usually reversed with surgery. If the hearing loss is mild and the tumors are small, hearing may be saved by removing the tumor.Sensorineural hearing loss from disease in the central nervous system may respond to medical management. When hearing aids are not enough, this type of hearing loss can be treated with cochlear implants.
