Cochlear Implants Hyderabad
What is a Cochlear Implant?
A cochlear implant is a device that provides hearing sensations for severely and profoundly deaf individuals who derive no significant benefit from hearing aids.
What are the benefits of a Cochlear Implant?
Recipients of a cochlear implant obtain a wide range of sound information and auditory experience including:
- Improvement in the detection of environmental sounds, such as a knock on the door, the doorbell, or telephone ringing, traffic noise, kitchen utensils, dogs barking and background music.
- Increased ability to recognise speech with lip-reading.
- An improved ability to understand speech using hearing alone.
- Improvement in voice monitoring and speech production.
- Most implant users report increased ease and enjoyment in communication with family and friends.
How does it work?
Speech and environmental sounds are picked up by the sensitive microphone of the external speech processor. The sound is converted into a digital signal by the processor and sent to the implant via the transmitting coil. The coil sits over the implant package and is held in place by magnet attraction between the internal and external magnets. The digital signal is received by the implant package and a code of electrical signals is sent to the active electrode array in the cochlea. The sensory hearing cells in the cochlea (spiral ganglion cells) are electrically stimulated and a nerve impulse is sent along the auditory nerve which is perceived in the auditory cortex as a sound.
