Cochlear implants are electronic devices that improve hearing. They are used for hearing loss treatment for those having severe hearing loss from damage to the inner ear and can’t hear properly with hearing aids. Unlike hearing aids that work by amplifying sounds, cochlear implants bypass damaged parts of the ear so that sound signals are delivered to the auditory nerve.
Cochlear implants are equipped with a sound processor that is placed behind the ear. This processor receives sound signals and directs those to a receiver that fits under the skin behind the ear. The signals are sent by the receiver to the electrodes implanted in cochlea (the snail-shaped inner ear). The auditory nerve is stimulated by the signals, which are then directed to the brain. Those are then interpreted as sounds by the brain, though these sounds won’t be like natural hearing.
Learning to interpret signals received from a cochlear implant takes time and training. Most people with cochlear implants make considerable progress in understanding speech within 3-6 months of use.
Cochlear implants aid people with severe hearing loss by improving hearing in them. These are people who are no longer aided by hearing aids. Cochlear implants help improve their quality of life by enhancing communication. Cochlear implants may be unilateral (placed in one ear) or bilateral (placed in both ears). At first, adults usually have one hearing aid and one cochlear implant. Then, they may progress to having two cochlear implants as the hearing loss advances in the hearing aid ear.
Oftentimes in children with severe bilateral hearing loss, cochlear implants are placed in both ears at the same time, especially in infants and children who are learning to speak and process language. Children aged 6-12 years and adults of any age can benefit from using cochlear implants.
Those having cochlear implants have reported improved:
To be eligible for a cochlear implant, you should have:
The surgery for cochlear implant is performed under general anaesthesia. It means that you or your baby will be in a sleep-like state while the procedure is being performed. The following instructions may be given before the surgery:
Before the procedure
You will have to undergo a detailed medical evaluation to help find out if cochlear implants are a good option for you. The evaluation that healthcare providers will conduct may include:
You will be working with a healthcare professional trained in assessing and rehabilitating hearing loss and related problems (an audiologist) and your surgeon to help find out the cochlear implant type that best suits your needs. All cochlear implants have internal and external parts. Your options include:
The surgeon will make a tiny incision or cut behind the ear and create a small hole in the part of the skull bone where the internal device rests. Then he will create a small opening in the cochlear so that the electrode of the internal device can be threaded. The incision is then closed with the help of sutures so that the internal device lies beneath the skin.
For a while, the patient might experience:
For activation of the cochlear implant, an audiologist will:
Rehabilitation involves training your brain to listen to comprehend the sounds heard through the cochlear implant. Everyday environment noises including speech will be heard differently from what you remember. Your brain requires some time to identify what these sounds mean. The process keeps going on and is best achieved by continuously wearing the speech processor during waking hours.
Regular follow-ups visits for the whole lifetime helps check the program on the device and perform auditory testing that can help you derive the most benefit from your cochlear implants.
The results of the cochlear implant surgery are not the same for every patient. They vary from person to person as they depend on different factors including age of hearing loss, length of the time between the hearing loss and the surgery. Children who are born with significant hearing loss get the best results if the cochlear implant is used from a young age. On the other hand, adults get the best results if the hearing loss before the cochlear implant is associated with a shorter period. Adults who have no or little experience with sounds tend to derive lesser benefit from cochlear implants, even though both adult groups generally improve post-cochlear implantation.

Following are some predicted outcomes after cochlear implant surgery:
A cochlear implant is a safe medical-electronic device that has been approved by FDA for providing an enhanced sound perception by bypassing the missing or damaged hair cells and directly stimulating the auditory nerve. It is a high performance and effective solution for those who have severe to profound sensorineural hearing loss.
A cochlear implant has two parts - external processor and internal implant. The internal implant is implanted surgically by an ENT specialist and after 3-4 weeks, the external processor is switched on by an audiologist where the implantee hears through the cochlear implant for the first time. After that, the complete post-cochlear implant rehabilitation programme starts.
