- QUESTION: My father lost his hearing as a young man, and now I find that I,
- too, am proceeding along the same path. His condition was diagnosed as a
- condition called "otosclerosis" and I can remember that it was a condition
- without a cure. He wore a hearing aid on and off until he died. I was
- hoping you might discuss this subject in your column and offer any thoughts on
- newer treatments that you might be aware of. I would be most grateful for any
- information you can provide.

- ANSWER: Otosclerosis is the most common cause of progressive hearing loss in
- younger adults of the conductive type. That means that something reduces the
- ability of the ear and all its mechanisms to pass (conduct) the sound waves
- from the outside of the head to the nerves in the inner ear that guide the
- sound, now in the form of electrical nerve impulses, to the brain. In the
- case of otosclerosis, it is the formation of new bone around the the stapes,
- one of the three small bones (ossicles) that transmit sound waves from the
- tympanic membrane to the inner ear. This new bone prevents the stapes from
- vibrating, and so the conduction of sound is diminished. It is a condition
- that is known to run in families, for more than 50 percent of patients
- diagnosed with the condition have a positive family history. It starts
- between the ages of 30 and 50, becoming progressively more severe. It usually
- occurs in both ears, although not always to the same degree and is frequently
- accompanied by a sensation of ringing or hissing in the ear (tinnitus). It
- appears to be more common in women than in men. A full audiologic evaluation
- including hearing tests is required to establish the diagnosis and its
- severity. It can be treated in several ways. Some specialized centers now
- use fluoride therapy that diminishes the progression of the disease by
- reducing the amount of new bone that is formed around the stapes. Many
- patients find that they are comfortable with the hearing they can obtain from
- the use of a hearing aid that amplifies the sound. The surgical approach is
- to remove the stapes (and extra bone), replacing it with an artificial
- prosthesis. This operation a "stapedectomy" is successful in from 90-95
- percent of patients and can be performed in the physician's office under local
- anesthesia in many cases.
