Cochlear implants: everything you need to know

A cochlear implant is an electronic instrument that enables people to regain some hearing.  Implants are for patients who have considerable hearing impairment due to internal- ear damage and have exhausted all other choices, including external hearing aids, which are usually also a feasible alternative.

In contrast to hearing aids, which enhance sound, a cochlear implant sends acoustic waves directly to the auditory nerve, bypassing any damaged parts of the ear. Cochlear implants use an auditory processor that sits behind the ear lobe. The processor captures sound waves and sends them to a sensor implanted underneath the epidermis behind the ears. The receiver sends signals to sensors in the middle ear, which are shaped like a snail (cochlea).

The impulses stimulate the auditory nerve, which then transmits the data to the brain. The brain converts such impulses into frequencies, although the sounds will not be comparable to those typically heard.

Deciphering signals from a cochlear implant requires patience and practice.The majority of cochlear implant users improve their communication skills within a year.

Who can stand to gain from a cochlear implant?

The preceding are preliminary guidelines; candidacy is determined by several other factors. To find out if a cochlear implant is right for you or a loved one, talk to your audiologist, ENT physician, or a hearing medical expert.


A cochlear implant may be appropriate for children as young as one year.  Experts recommend that children be ingrained as soon as possible so that they can be exposed to sounds early during the vital period of the language acquisition process. They’ll require a lot of language development treatment after the device is placed to achieve the best results from it.

  • A child is considered a credible contender if they fulfill these eligibility requirements:
  • Both ears have a substantial hearing impairment.
  • Hearing aids are either ineffective or unhelpful.
  • Are in good health and would not endanger the procedure if they had a health problem.
  • Recognize their contribution to the successful use of cochlear implants with their parents.
  • Get help and support from a school that promotes the development of auditory skills.


A cochlear procedure may be an option for grownups who have ended up losing their hearing pre or post-communicating learning. People who learned to talk before losing their ability to hear, also postlingually deafened, have a better cochlear implant rate of success than individuals who did not recall speaking before losing their ability to hear in a state called prelingually deafening. Individuals who cover these basic requirements are typically considered the best implant candidates:

  • In both ears, you have a low to moderate hearing impairment.
  • Hearing aids are either ineffective or useless for you.
  • They have no medical conditions that could put their surgery in jeopardy.
  • In the deaf community, you have a strong desire to communicate via listening, reacting, and speechreading.

What are the signs you may be a good candidate for cochlear implants?

A variety of specialists are involved in determining whether a patient is a good fit for cochlear implants, including a neurosurgeon, an audiologist, and, in some cases, an auditory-based therapist. It is possible that one or more of the following activities will be required:

  • The whole audiological diagnostic assessment: You should have had a recent hearing test done on you. These tests are used to identify the degree of hearing impairment and to help choose the best follow-up treatments or technologies.
  • Evaluation of a cochlear implant: Your current hearing aids will be evaluated to determine how well they function and how well they allow you to function. This exam will establish if your wearable devices are providing you with the greatest feasible hearing or if you require implanted auditory devices.
  • MRI or CT scan: These tests disclose the inner structure of the inner ear.
  • Appointment with doctors and surgeons: Before operations, the surgeon will go over the instructions, the procedure, and what to expect in terms of recuperation and probable auditory outcomes with you. In terms of hearing, talking, and writing, communication abilities are evaluated.
  • Balance testing is used to assess the vestibular (balance) system. The architecture that controls hearing is interwoven with the network.

Cochlear Implants: how effective are they?

Cochlear implants have a high success rate. The individual must be informed of the operation and set realistic goals. A cochlear implant will help you understand what you’re saying, but it won’t fix your hearing impairment. Patients should get a more precise transmission with this procedure than with their hearing devices, and their hearing should improve overall.

What can you expect with cochlear implants?

The cochlear implant procedure is usually performed as an outpatient surgery. Following the surgery, each patient is closely observed by trained personnel.

Recipients of cochlear implants can detect sounds, especially speech, in an appropriate manner. Most persons with implants gain the ability to differentiate and comprehend speech in quiet environments without visual cues. The majority of people are capable of talking on the phone, listening to music, and speaking clearly.

Patients who have had severe to significant hearing impairment for a brief duration have had the best results. Cochlear implants, on the other hand, can help people who have had hearing loss for decades. Particular hearing situations, like those with foreground noise or those with no visual clues, such as talking on the phone, can be difficult. Aural therapy and cochlear implant extra training may help improve performance.

Nonetheless, under these difficult conditions, receivers’ levels of accomplishment vary greatly. Endurance, persistence, and, at first, frequent programming sessions are required to learn to hear and understand with a cochlear implant. Those who commit to regular “training” with the processor usually make the fastest gains.

What is the procedure for receiving an implant?

To check if you or a beloved one is a candidate for an implant, you’ll have to go through audiometry and psychiatric screening, a health assessment, and radiological examinations. You must also go through psychotherapy to assure that you understand the substantial follow-up that will be required after the implant surgery, as well as what to expect in terms of device performance and constraints.

Cochlear Implantation is a procedure that involves implanting a cochlear

The insertion technique is frequently performed under general anesthesia after that. On average, it takes 2 to 4 hours, and most people stay in the institution overnight. At this moment, the person will be incapable to hear. Even after the internal parts have been implanted, the surgical region must heal before the exterior gadget can be installed.


4 to 6 weeks after surgery, the patient will return to the auditory implantation center to have the external device implanted. At this session, the audiologist will activate cochlear implantation and begin the mappings procedure for the individual’s specific needs.

After their cochlear implant is “turned on,” most children and adults hear for the first time. Hearing their spouse’s voice, a relative’s speaking manner, or the audiologist’s words for the first time is an emotional and lasting milestone for the client or caregiver.


Additional fine-tuning and adjustments to the cochlear implant mappings will be made as the patient begins their new hearing experience. Most patients may need several follow-up consultations for few weeks to fine-tune the signal mappings to the electrodes and help them become adjusted to their device.

Individuals should schedule regular sessions with a hearing specialist to understand how to recover the ability to hear new sounds. In the same way as hearing aids, hearing-impaired individuals will want to visit their audiologist regularly for long-term hearingtesting.
