Are you aware with the term Cochlear Implant? Cochlear is that part of the ear which has tiny hair cells. It is the inner ear. Often due to prolonged exposure to loud noise and other factors the tiny hair cells in the inner ear gets damaged. Thus with it you would suffer from hearing loss. This type of hearing loss is also known as “sensorineural hearing loss”. Cochlear Implant is the implantation of an electronic device through surgery. This is generally done if your hearing loss is extremely severe. With the cochlear implant a bypass is made to the damaged hair cells and brings about the direct stimulation of the auditory nerve. The results of this surgery may vary from person to person. For some this may indeed be life changing. But there are certain risks involved as well.
In this blog we will try to make you aware of the benefits and the risks involved with Cochlear Implants.
What the procedure is?
The procedure in which the device is implanted is usually done under general anesthesia. The device contains an external part which consists of a microphone which is used to pick up on the external sounds. It transmits the same to the speech processor. This is a box type unit which analyzes the sound signals transmitted. The internal devices have an array of electrodes which are directly connected to the auditory nerve and thus get stimulated to provide the sensation of sound.
The benefits of Cochlear Implant
The benefits of successful cochlear implantation are many. Following the surgery you may be able to hear the speech and other sound at a normal level. You would get the maximum results within the first 3 months of the surgery. However following this period there may be further improvement in your hearing but at a reduced rate.
With it you may be able to follow speech much better. This may be with lip reading or without it, in those very successful cases. You may be able to make telephone calls and able to follow what is being spoken over the telephone. You can even enjoy music and while watching television where you may be able hear the audio on the television at the same time.
Risks of the procedure:
In spite of its benefits there are many risks associated with the surgery as well. These include risks of injury to the facial nerves. There are many nerves which move through the middle ear into the face. During the surgery, if it is not carefully done, then there is risk of damage to these facial nerves.
There is also the risk of leakage of the cerebral spinal fluid. Our brain is surrounded by this fluid. During the surgery there is also a great risk of this fluid getting leaked as well. Moreover other risks include the risks of infections too. Other risks include Tinnitus– a ringing or buzzing sound in ear, numbness around the ear, etc.
So if correctly done the benefits of Cochlear implants are many. But the risks associated with this procedure are great too. Thus in case you are suffering from sensorineural hearing loss, then you must consult a reliable audiologist. If you decide to go ahead with this surgery, you must ensure that it is done by a competent surgeon who would do the surgery properly.
