What is Otosclerosis?

The Term Otosclerosis is derived from the Greek words for “hard” (sclera-o) and “ear” (oto). Behind the ear drum, there are 3 ossicles, which are media for transmitting the sound waves towards the inner ear & then to the brain.

These ossicles are :
  1. Malleus
  2. Incus
  3. Stapes
It is 3rd ossicle, stapes which gets fixed by new bone deposition around its footplate hampering the mobility of the ossicle & by this causing conduction blockage in sound waves, resulting in hearing loss.
