Hearing is a very important aspect of any body’s
life it is a process in which human being listen to a particular sound
and derive meaning from it. Ears are completely developed part of human
body which responds to the slightest sound as well as to the loudest
sound, but there are few people who face the complete hear loss due to
the injury in sensory cells, this loss is so intense that even the
hearing instruments can’t help them, at that point of time cochlear implant is a complete solution to be the part of hearing world once again.
- What is Cochlear implant?
This type of device is an electronic device which is
planted in the human body to help the patient listen better, this
implant is not a proper remedy for deafness, but it is an alternative
for sound. This technology helps the patient to hear and understand the
world in more efficient manner. But for the effortless working of
device, it’s important to have the existence of auditory nerve because
if these nerves are injured to the extreme level then it will not
accept the signals making the implantation a total waste. The sound
captured by this instrument is very different from the natural sound.
This device is very robust because it helps the patient to hear the
sound clearly in noise, let them enjoy the music and they can wear
their instrument during swimming or running.
- Points to note before using Cochlear implant
Before using the cochlear implantation, it is
important to understand the level of damage in the ear therefore,
different types of tests are performed on patient’s ear drum, middle
ear bone and middle ear. This type of test is known as tympanometry,
where the device is injected in the patient’s ear canal which will
change the ear pressure by generating pure tone and calculating the
activity of eardrum on the basis of different sounds and pressures.
These results are delivered in a curve which is known as Tympanogram.
This process of implantation is termed as mapping, where the device can
be planted to infants, children’s and adults. There are many trained
professionals who help the patient’s cope up with the new
transformations.
Plantation of cochlear device is a very crucial step for any person who faces hear loss, because it will affect him throughout his life. Cochlear implantation is one step towards the hearing world for some people.
