COCHLEAR PROSTHESIS Meaning and
Definition
-
A cochlear prosthesis, also commonly referred to as a cochlear implant, is a medical device designed to restore partial hearing to individuals with severe to profound sensorineural hearing loss. The device consists of two main components: an external portion and an internal portion.
The external component includes a microphone that captures sound and converts it into electrical signals. These signals are transmitted to the internal component, which is surgically implanted in the inner ear, specifically the cochlea.
The internal component consists of a receiver-stimulator, which receives the electrical signals from the external portion and transforms them into electrical impulses. These impulses are then sent to an array of tiny electrodes positioned inside the cochlea. These electrodes stimulate the auditory nerve fibers that normally transmit sound signals to the brain.
By bypassing the damaged or non-functioning hair cells within the cochlea, the cochlear prosthesis enables individuals with hearing loss to perceive sound. The brain interprets these electrical impulses as meaningful sounds, allowing the wearer to distinguish speech, environmental sounds, and other auditory stimuli.
Cochlear implants can greatly improve the quality of life for individuals with severe hearing loss who do not benefit from conventional hearing aids. With appropriate training and rehabilitation, users of cochlear prosthesis can achieve better speech understanding and a greater ability to communicate effectively in various listening environments.

Etymology of COCHLEAR PROSTHESIS
The word "cochlear" originates from the Latin term "cochleāre", derived from "cochlea", which means "snail". In ancient Roman culture, the snail shell was called "cochlea" due to its spiral shape and resemblance to the cochlea in the human inner ear.
The term "prosthesis" comes from the Greek word "prosthesis", which means "addition" or "attachment". It is used to describe an artificial device or body part that is used to replace or enhance a missing or impaired body part.
Therefore, when combined, "cochlear prosthesis" refers to an artificial device or implant used to replace the functions of the cochlea, which is the snail-shaped structure in the inner ear responsible for hearing.
