Chronic Ear Disease
This is a fairly common condition often associated with continuous or intermittent drainage from the ear canal. As a rule these patients also have a hearing loss and often need amplification. A conventional air conduction aid with a mold placed in the ear canal opening is often impossible to wear due to the drainage – and may even provoke drainage. If the hearing loss is significant an air conduction aid may have difficulty to overcome the dysfunction of the eardrum and middle ear bones. The solution for these patients is a bone conduction hearing device bypassing the middle ear and stimulating the inner ear directly through the skull. Transmission of sound in the bone is very good with minimum of attenuation and very little distortion. In fact the hair cells of the inner ear cannot tell if the sound is coming the normal way through the external ear canal and middle ear or via vibrations in the bone.

Famous quotes containing the words chronic, ear and/or disease:
“Perhaps our originality manifests itself most strikingly in what we do with that which we did not originate. To discover something wholly new can be a matter of chance, of idle tinkering, or even of the chronic dissatisfaction of the untalented.”
—Eric Hoffer (1902–1983)
“All things are wearisome; more than one can express; the eye is not satisfied with seeing, or the ear filled with hearing. What has been is what will be, and what has been done is what will be done; there is nothing new under the sun.”
—Bible: Hebrew, Ecclesiastes 1:8-9.
“For somehow this disease inheres in tyranny, never to trust one’s friends.”
—Aeschylus (525–456 B.C.)
