Cochlear Implants Are an Advanced Form of Hearing Aid That Helps Individuals

Posted by Pooja basmunge on June 21st, 2021

A cochlear implant, also known as a cochlear adapter, is a surgically planted neuroprosthetic device that gives a disabled person a modified hearing capability. CI adapters bypass the natural audible sound system to directly access the cochlear nerve, replacing it with electrical signals that directly stimulate the cochlear muscle. The results are immediate and effective. Patients find that they can perceive sound above or beyond the binaural field normally reserved for normal hearing.

This procedure has been on the market for several years, but only recently has it become available to patients with one ear. Most devices have been placed in the upper ear, but some cochlear implants can be placed in either ear. The excimer laser essentially shaves off the hair cells that surround the cochlear nerve, effectively removing the device from the ear. The result is a smaller signal carried by fewer cells, making the device easier to insert and more sensitive to environmental sounds. The result is clearer speech patterns that are louder and less distorted.

There are several types of cochlear implants available for insertion into the ear; all share basic features. The principle of their manufacturing remains the same. They are all made of a synthetic material called ceramics. Once the device is secured into the ear, a plastic tube or "cubit" is inserted into the side of the ear. A hearing aid connector is then secured on the top of the Cubit; this connection serves as the link between the Cubit and the outside world.
