Otosclerosis is an abnormal growth of the bones in the middle ear, which causes hearing loss. In many cases, a surgical operation may restore the hearing. Otosclerosis is one of the most common causes of progressive hearing loss in younger adults. What is Otosclerosis? What causes Otosclerosis? Find out more at hear-it.org
Otosclerosis is most often caused when one of the bones in the middle ear, the stapes, becomes stuck in place. When this bone is unable to vibrate, sound is unable to travel through the ear and hearing becomes impaired (see illustration).
Otosclerosis is a type of hearing loss involving the middle ear. It is a result of abnormal bone growth in the ossicles of the inner ear, usually of the stapes, which is one of the 3 inner ear bones (ossicles) involved in the conduction and amplification of sound.
Otosclerosis is a condition in which there's abnormal bone growth inside the ear. It's a fairly common cause of hearing loss in young adults. There are 3 tiny bones deep inside the ear that vibrate when sound waves enter. They transmit sound waves to the cochlea (inner ear), which converts them into signals that are sent to the brain.
Otosclerosis is a rare condition that causes hearing loss. It happens when a small bone in your middle ear-- usually the one called the stapes -- gets stuck in place. Most of the time, this ...
The ear is divided into three parts - the outer (external) ear, the middle ear, and the inner ear. The middle ear behind the eardrum is filled with air. Air comes from the back of the nose up a thin channel called the Eustachian tube. In the middle ear there are three tiny bones (ossicles) - the hammer (malleus), anvil (incus) and stirrup (stapes).
In a normal ear, sound vibrations are funneled by the outer ear onto the ear drum, or “tympanic membrane.” The ear drum sends these vibrations to the small bones in the middle ear: the malleus (hammer), incus (anvil), and stapes (stirrup). When the stapes bone moves, fluid in the inner ear moves and stimulates hair cells in the inner ear.
According to LivingNaturally.com, people with this condition have a decreased level of a type of white blood cells that are known as neutrophils. Osteosclerosis also inhibits the natural absorption of nutrients from the digestive tract. People who are suffering from osteosclerosis tend to be short in stature, and they normally have delayed growth.
Otosclerosis is a disease of the bones of the middle ear and the bones of the inner ear. The bones of the middle ear are labeled the malleus, incus and stapes (2-4) in figure 1, and are also known in aggregate as the "ossicles".
The primary form of hearing loss in otosclerosis is conductive hearing loss (CHL) whereby sounds reach the ear drum but are incompletely transferred via the ossicular chain in the middle ear, and thus partly fail to reach the inner ear . This usually will begin in one ear but will eventually affect both ears with a variable course.
