The ear is a remarkably complex and efficient hearing system. The whole process of hearing takes place in a fraction of a second.
When hearing aids are not effective in people with severe-to-profound hearing loss, medical experts consider a cochlear implant to be a more effective long-term solution.
Unlike hearing aids, cochlear implants don’t just increase sounds. They mimic the natural hearing function of the inner ear through electronic stimulation.
The system has two parts – an external sound processor and the actual cochlear implant. External sounds are received, processed into electrical signals, and then passed on directly to the hearing nerve (or auditory nerve), completely bypassing the injured parts of the inner ear.
You are a good candidate for a cochlear implant if you find the following when you use a hearing aid-
The surgery for the cochlear implant procedure typically takes about 1 to 3 hours. Multiple cochlear implant surgeries are performed each year. The associated risks are small, and your ENT surgeon will talk about them with you.
A cochlear implant is a small electronic device that is surgically implanted to help profoundly deaf people hear. It can be used for people who are completely or almost completely deaf in both ears, and get almost no improvement with hearing aids. It has to be noted that a cochlear implant is not the same thing as a hearing aid because a cochlear implant is surgically implanted and works in a different way. A hearing aid just makes the sounds louder but a cochlear implant does the work of damaged parts of the inner ear (called cochlea) to send sound signals to the brain.
You should understand that a cochlear implantation surgery is a major surgery and is very expensive procedure. Before undergoing cochlear implantation surgery, you need to understand the benefits of this surgery and know whether you are eligible to undergo this surgery. The following are the few important points that you should know before undergoing this procedure.
5 Before undergoing cochlear implantation surgery, you must have a medical evaluation by an ENT specialist. This evaluation may include radiology tests like a CT scan or MRI scan of the brain and the middle and inner ear.
The external sound processor captures sounds and then filters and processes it. The sound processor then translates the filtered sounds into digital information. The digital information is then transmitted to the internal part of the cochlear implant system. The internal implant of the cochlear implant system converts the digital information into electrical signals, and sends them to a tiny, delicate curl of electrodes that sits gently inside your cochlea. These electrical signals from the electrodes stimulate the hearing nerve bypassing the damaged hair cells that result in hearing loss. This allows the brain to perceive sound.
There are various factors that need to be taken into consideration before you undergo cochlear implantation surgery.
A cochlear implant surgery is an expensive surgery. It is the cost of the implant that makes the surgery very expensive. The cochlear implant is a very sophisticated device and is manufactured by different companies under different brand names. Further there are different types of cochlear implants that have different features and specifications. The cost of cochlear Implant depends on make and specifications and hence you will find a huge variation in the cost of cochlear implant surgery package. There are different cochlear implant surgery packages (with different types of implants) and the cost varies depending upon the type of cochlear implant you choose.
