COCHLEAR PROSTHESES Meaning and
Definition
-
Cochlear prostheses, also known as cochlear implants, are electronic medical devices designed to provide artificial hearing for individuals with severe to profound hearing loss. They are essentially surgically implanted devices that bypass damaged or non-functioning parts of the inner ear (cochlea) and stimulate the hearing nerve directly, allowing sound signals to be transmitted to the brain for interpretation.
The cochlear prosthesis consists of two main components: an external speech processor and an internal implant. The external component captures and analyzes sound from the environment and converts it into digital signals. These signals are then transmitted to the internal implant through a transcutaneous magnetic link.
The internal implant, typically placed during a surgical procedure, consists of two main parts: an electrode array and a receiver-stimulator. The electrode array is inserted into the cochlea and its electrodes stimulate the auditory nerve fibers directly. The receiver-stimulator receives the digital signals from the external processor and translates them into electrical impulses that are delivered to the appropriate electrodes in the cochlea.
Once the electrical impulses reach the auditory nerve fibers, they are transmitted to the brain, where they are interpreted as sound. With training and time, individuals with cochlear prostheses can learn to understand speech and sounds, enabling them to communicate effectively in various listening environments.
Cochlear prostheses have revolutionized the treatment of severe hearing loss and have significantly improved the lives of those who were previously unable to benefit from traditional hearing aids. They have become a widely accepted and effective solution for individuals with profound hearing loss, offering them the opportunity to regain a sense of sound and enhance their overall auditory experience.

Etymology of COCHLEAR PROSTHESES
The word "cochlear" comes from the Latin word "cochlea", which means "snail shell". It is derived from the Greek word "kochlias", also meaning "snail shell". This term refers to the spiral-shaped inner part of the ear, which is involved in hearing and resembles a snail shell.
The word "prostheses" is the plural form of "prosthesis", which comes from the Greek word "prosthesis", meaning "addition" or "attachment". In medical terminology, a prosthesis refers to an artificial device that replaces a missing body part, such as a limb or organ.
Therefore, "cochlear prostheses" refers to artificial devices or implants used to replace or enhance the function of the cochlea, particularly in cases where individuals have severe hearing loss or are deaf.
