Cochlear Implants FAQ: Explained by Experts

Cochlear implants are remarkable devices that have transformed the lives of people suffering from severe hearing loss or deafness. Despite their growing popularity, many questions persist regarding their function, eligibility, and effectiveness. In this comprehensive FAQ guide, we aim to address the most common inquiries about cochlear implants to help you make an informed decision.

What is a Cochlear Implant?

A cochlear implant is an electronic medical device that bypasses the damaged hair cells in the inner ear, or cochlea, to provide sound signals directly to the brain. Unlike hearing aids, which amplify sound, cochlear implants replace the role of the damaged cochlea to facilitate the hearing process.

Who is Eligible for a Cochlear Implant?

Cochlear implants are generally recommended for individuals with severe to profound sensorineural hearing loss in both ears. Criteria for implantation may include:

  • Limited benefit from hearing aids, as confirmed through specialized hearing tests.
  • No medical contraindications, such as chronic ear infections or anatomic irregularities.
  • High motivation and realistic expectations regarding the outcome.

What is the Implantation Procedure Like?

Cochlear implantation is a surgical procedure typically performed under general anesthesia. It involves making a small incision behind the ear to implant the device’s internal components, including an electrode array that is inserted into the cochlea. The surgery usually takes between 1 to 3 hours, followed by a recovery period.

How Effective Are Cochlear Implants?

Effectiveness can vary from person to person. Factors such as age at implantation, duration of hearing loss, and post-operative rehabilitation can impact outcomes. However, most recipients experience significant improvements in speech understanding, especially in noisy environments.

Will a Cochlear Implant Restore Normal Hearing?

While cochlear implants can significantly improve the ability to perceive sound and understand speech, they do not restore “normal” hearing. Users often describe the sound as “mechanical” or “electronic,” particularly in the early stages of use.

What is the Rehabilitation Process?

Cochlear implantation is not a one-time fix but a process that involves considerable auditory rehabilitation. Users undergo therapy sessions to learn or re-learn how to interpret the sounds transmitted by the implant. This process may take weeks or months, depending on individual circumstances.

Are Cochlear Implants Covered by Insurance?

In many cases, cochlear implants are covered at least partially by health insurance policies, both private and public. It’s essential to consult with your insurance provider for specific details regarding coverage and associated costs.

Are There Risks Involved?

Like any surgical procedure, cochlear implantation carries some risks, including infection, anesthesia complications, and device malfunction. However, the procedure has a high success rate and complications are relatively rare.

Can Children Receive Cochlear Implants?

Yes, cochlear implants are approved for children as young as 12 months with profound sensorineural hearing loss. Early implantation is often recommended to capitalize on critical periods of language development.


Cochlear implants offer a life-changing opportunity for individuals with severe to profound hearing loss. However, it’s a decision that requires thorough research and medical consultation. Knowing the answers to these frequently asked questions can serve as a foundational step in making an informed choice. For a personalized treatment plan and to discuss eligibility, it is essential to consult with a qualified audiologist and medical team specialized in hearing health.

This is hands down the best place for anyone looking for an audiologist. Very individual attention to you and your needs. I use to go to 1 of the big ENT group and they never tweaked my hearing aids like Dr. C and Gayle do. You are not a number here. Was upset that things might change when Dr. Seaborg retired but not so..the same excellent service. Christina found someone who could fill her very big shoes (been coming for 9+ years.) I tell everyone they need hearing aids that this is the place to come. I brought my 82 year old mother-in-law and Dr. C and Gayle are always soooo patient with her. Thank you for the same awesome awesome care. Ive been wearing hearing aids for over 20 years and I am hearing better now than I did 10 years ago.

I visited Premier Audiology & Hearing Aid Center without an appointment to see if they could help resolve a problem with the hearing aids of a relative, who is 97 years old. Dr. Cabrera and Gale Prakin were most accepting, accommodating and helpful. They are an asset to the community and profession.

Dr. Cabrera took the time to carefully listen to my concerns, and then to explain my test results and options. He even kept prompting me to ask more questions to ensure that I understood what my test results meant. He is clearly interested in finding the correct diagnosis and best solutions.
