Why have a cochlear implant when hearing aids are available?

Hearing aids amplify sounds so that the residual part of the ear can use it to hear. A cochlear implant transforms sound into electrical current that is used to stimulate the hearing nerve directly and bypass the damaged parts of the cochlea.

What does a cochlear implant sound like?

Each person is unique and so is their hearing loss and their anatomy. We can never truly say what things sound like for each individual user. The brain moulds itself according to the input it receives. Research has indicated that the brain takes the input and use it. Adults sometimes report that the sound is originally very high pitched and electronic, but over time it becomes familiar. The sound of a cochlear implant is usually the only sound a young child will hear and that will be his “normal”. What sounds “natural” or “normal” to a person with typical hearing is not “normal” to a person with hearing loss.

Truths and myths about cochlear implants

Cochlear implants are not experimental devices. Cochlear Implants have been approved by the FDA in America and other by similar bodies in the rest of the world. It has been successfully used since the early 1980’s.

Cochlear implant surgery is not brain surgery and does not go into the brain. During the surgery, a small incision is made behind the ear. The surgeon lifts the skin away from the underlying bone, and uses surgical drills to create a “well” for the internal implant components to sit in between the skin and the skull. At no time is the brain casing breeched or compromised in any way.

What will I/my child be able to hear with a cochlear implant?

Cochlear implants provide a wide range of sound information. Outcomes vary amongst individuals.

You will possibly hear most sounds from soft to loud sounds. Cochlear Implant users report that they can hear footsteps, doors closing, ringing telephones, car engines, barking dogs, lawn mowers, birds and various other environmental sounds. You will also be able to hear your own voice better and be able to control the volume of your voice better, even in the presence of other sounds.

Together with time and the right rehabilitation, most people is able to hear and understand more speech than with hearing aids. Many cochlear implant users are able to use the telephone and enjoy music.

Does a cochlear implant provide normal hearing?
The cochlear implant:

  • will NOT provide normal hearing
  • will NOT guarantee intelligible speech or age appropriate language skills
  • will NOT guarantee educational success or increased performance in the work environment

Nonetheless, with constant use of the cochlear implant and continuing training, the sound you will hear through the implant should become more meaningful and should enhance your ability to communicate.

What will be my child’s outcomes with a cochlear implant?
It is not possible to predict how well any child will progress with a cochlear implant.

A child’s progress will be influenced by many factors, for example:

  • the age of onset of the hearing loss
  • the duration of the child’s hearing loss
  • family and educational support
  • family’s and child’s motivation
  • child’s level of speech language development
  • child’s cognitive development and learning style
  • existence of a cochlear abnormality
  • regular and continuous of use of the device
How will I/my child keep up with new technology?

The internally placed implant unit is designed to last a lifetime and involves only the initial surgery. The cochlea is already adult size at birth and most of the skull structures are fully grown by the age of 2 years. The electrode is designed to accommodate for skull growth.

The externally worn speech processor, which is responsible for sending information to the internal electrode, can be upgraded as technology evolves.

Should I/we wait for newer technology?

No. There has been very little change in the design of the surgically implanted unit in relation to the history of cochlear implantation.

Significant developments have been shown in the way in which the processor makes use of speech (speech coding strategies) and delivers the signal to the internal unit.

The speech processor can incorporate new technology when available.

For children, there is a small and precious window of time to give them access to hearing if you desire listening and speech. It is more important to deliver stimulation to the hearing nerve and auditory centres of the brain. The longer the duration of the hearing loss, the longer it takes to achieve op mal results and learn to hear again.

Am I too old / is my child too young for a cochlear implant?

Providing you are medically fit, no one is too old. The oldest person in the world to receive a cochlear implant was 102 years old. Outcomes are better for children born deaf who receive their cochlear implant (s) before 12 months of age. Children as young as 6 months of age can receive cochlear implants.

What can I expect at activation?

The day of your initial activation will be lifechanging. The initial activation is generally scheduled two to four weeks after implantation. Anticipation of this important day may be filled with hope, excitement, and varied expectations.

When your cochlear implant system is first activated, the objective is to find a comfortable volume level across the frequency (pitch) spectrum so that your first sound program or “map” can be set. If you can distinguish between a loud or soft sound at your first activation appointment, the day has been a success and you have started your hearing “journey”.

How do I get a cochlear implant?

A thorough assessment is needed by the cochlear implant team. Please read the section on our website (How to get a cochlear implant) for more detailed information.

What about playing sports or swimming with a cochlear implant?

Yes, people with cochlear implants can participate in nearly all types of sport activities when they have removed the external equipment (or if the speech processor is water resistant).

The only restriction relates to skydiving and scuba diving (>25m) because significantchanges in air pressure are not advised. Partaking in all other activities is unrestricted, even though protective headgear is always recommended during contact sports. Discuss your specific needs with your case manager before partaking in contact sports.

The latest speech processors have waterproof housings available that also makes it possible to swim or bath/shower with your cochlear implant.

Can I go through security gates at airports or fly with a cochlear implant?

Yes. People with cochlear implants can go through the gates, but be prepared that it could trigger the alarms. It is recommended that you carry a card provided by your audiologist which will indicate that you are a cochlear implant recipient.

Benefits of bilateral cochlear implants

The ability to hear sound with both ears gives the effect of hearing in stereo. It enables you to pick out soft or distant speech, distinguish speech better in background noise and helps to determine which direction the sound is coming from.

Do medical aids pay for cochlear implants?

Since cochlear implants are recognized as standard treatment for severe to profound deafness, most medical aids cover/partially cover the costs. The PCIU will assist you to obtain prior authorization from your medical aid company before the surgery can take place.

What about guarantees and repair costs?

The internal implant carries a 10-year guarantee. Most external speech processors carries an initial 3-year warrantee.

You will have to pay for repairs that are out of warrantee periods or not covered by your insurance or medical aid.
