The ossicles are three tiny bones contained in the middle ear that are essential in conducting sound. They are called the malleus (the hammer), incus (the anvil), and stapes (the stirrup). They are connected by synovial joints and ligaments. Sometimes the three bones are referred to as the ossicular chain.

Specifically, it’s a hardening of the base of a very small bone called the stapes. After a positive diagnosis is made with image tests to rule out other potential sources of hearing loss, a stapedectomy may be performed if other treatment options aren’t effective.
