Anvil
Anvil (medical)
Anvil (pronounced: /ˈanvɪl/), in the context of medicine, refers to a small, cone-shaped piece used in stapedectomy surgery to replace the patient's natural stapes bone. The term originates from the Old English word anfilt, which means "to forge".
Etymology
The term "anvil" in English is derived from the Old English anfilt, or onfilt, which has a meaning related to forging or shaping metal. In the context of medicine, the term is used metaphorically to describe a tool used in ear surgery that resembles a blacksmith's anvil in shape.
Usage in Medicine
In a stapedectomy, the surgeon removes part or all of the patient's stapes bone in the middle ear, which may have become hardened due to otosclerosis. The anvil is then used as a replacement for the stapes. It is typically made of a biocompatible material such as stainless steel or titanium, and is designed to restore the patient's hearing by allowing sound vibrations to pass from the eardrum to the inner ear.
