Otosclerosis
is an abnormal bone growth in the middle ear that causes hearing
loss.
Causes of Otosclerosis
The
cause of otosclerosis is unknown. However there is some evidence that
it may be passed down through families. Growth prevents the ear bones
from vibrating in response to sound waves. Such vibrations are needed
in order for you to hear.
Otosclerosis
is the most common cause of middle ear
hearing loss in young adults. It typically begins in early to
mid-adulthood. It is more common in women than in men. The condition
may affect one or both ears.
- Hearing loss (slow at first, but gets worse over time)
- Vertigo or dizziness
- Ringing in the ears(tinnitus)
Otosclerosis
may slowly get worse. The condition may not need to be treated until
you have significant hearing problems.
Medications
such as fluoride, calcium, or vitamin D may help to slow the hearing
loss, but the benefits have not yet been proved.
Surgery
to remove part of the ear (stapes) and replace it with a
posthesis
can
cure conductive hearing loss. A total replacement is called a
stapedectomy. Sometimes only part of the stapes is removed and a
small hole is made in the bottom of it. This is called a stapedotomy.
