About This Presentation

Description : Check out this medical PowerPoint presentation titled "The Cochlear Implant" by Jackie Mitchell.

This medical PowerPoint presentation is about cochlear implant, a small electronic device that is surgically implanted in the inner ear to provide a sense of sound to people who are severely hearing impaired or deaf. It works by bypassing the damaged parts of the ear and directly stimulating the auditory nerve with electrical signals.

The implant consists of two main parts: an external speech processor, which captures sound and processes it into digital code, and an internal implant, which receives the code and sends electrical signals to the auditory nerve.

Cochlear implants are typically recommended for people who have severe to profound hearing loss and who are not able to benefit from traditional hearing aids. The implant can provide significant improvements in speech recognition and understanding, although it may not fully restore normal hearing.

The surgical procedure to implant the device is generally safe and well-tolerated, although it does carry some risks, such as infection, damage to the facial nerve, and device failure. Rehabilitation and training are also necessary to help the patient adjust to the new way of hearing and learn how to use the device effectively.

Today’s presentation will include: Cochlear Implants Trouble shooting Learning to Listen
Slide 3-

Sensorineural hearing loss Caused by problems in the cochlear.
Slide 4-

What is the difference between hearing aids and cochlear implants? Hearing aids help many people by making the sounds they hear louder. Unfortunately, as hearing loss progresses, sounds need to not only be made louder, they need to be made clearer. Cochlear implants can help give you that clarity.
Slide 5-

What does it sound like?
Slide 6-

The cochlear implant Cochlear Implants are mainly used for people who have little or no useable hearing. Their hearing cannot be amplified enough using a hearing aid. They are now being use with children who have single sided deafness. Cochlear Implants are very useful but have their limitations. The Cochlear Implant doesn’t ‘fix’ the hearing.

Enemies of the cochlear implant People who mumble People who cover their mouths – with beards, hand, facemasks Background noise Faces in the shadows or darkness People who speak from a distance

Listening fatigue

Vocabulary Switch on – usually takes place about 2 weeks after the operation. Processor – the part worn behind the ear or on the magnet site (Kanso). Coil – the part worn on the magnet site. Mapping – programming of the implant. Accessories – other devices that can be used with the implant. CIC – Cochear Implant Clinic. CCC – Cochlear Care Centre. Unilateral – one ear. Bilateral – two ears.
Slide 10-

What does it cost? The cost of CIs is covered by the government until the person reaches 26 years of age. Some older people receive implants through Medicare – there is a waiting list and no guarantee of upgrades. Most people use their private health insurance. The cost of the processor is around $10,000. Accessories cost more. Some people are now receiving upgrades through the NDIS.
Slide 11-

Nucleus 7 Smallest behind the ear processor. Direct streaming from compatible devices. Can be controlled by buttons, app or remote control. Can be used with a Roger System via an adapter.
Slide 12-

Kanso 2 Released last year in Australia. Smallest, lightest off the ear processor. Rechargeable and can stream directly from devices.
Slide 13-

The cochlear implant in the classroom The Mini Mic 2 connects with the Cochlear Implant The iPad can stream straight to the Nucleus 7 or Kanso 2 The Roger Touchscreen can be used with a neckloop or with a Roger Receiver and an adapter

Troubleshooting
Slide 15-

OH NO! You need to have a plan for what to do when things go wrong. Does the child have an old speech processor that can be used as a spare? It needs to be reprogrammed every time the map is changed on the current processor. Ensure that the ‘Spares Kit’ is up to date. How are you going to communicate with the child if they are totally deaf? Don’t presume that the child can read lips. Some deaf people are very good at this, and some can’t do it at all.
Slide 16-

Batteries The Nucleus 7 operates using either a rechargeable or 2 disposable batteries. I use rechargeable batteries and swap them over every morning. I also carry the disposable battery case so that I have a backup – just in case. I would recommend that students do the same – the batteries are the big ‘blue’ batteries (675).
Slide 17-

Swimming The Cochlear Implant is ‘splash proof’ but not waterproof. Families can purchase the Aqua + accessory for swimming. You must use rechargeable batteries with the Aqua +. It’s a bit tricky to use and I would suggest that you watch the video below before attempting to use it. https://youtu.be/w2nRrpRZ1R8 Do not twist the coil! It looks as though it should be twisted but don’t do it.

Word level listening Given a list of familiar words (names, foods, etc) the listener listens to the word and identifies the correct word. We begin with 3 very different words – peas, bananas, eggplant – and gradually increase the number of words and degree of difficulty. As the listener progresses we work on minimal pairs – contrasting 2 words with two different sounds eg. shake and ship, then one different sound eg. sip and ship.
Slide 21-

Sentence level listening We begin with 3 very different sentences or phrases – Go home. I’m going to school now. We play netball at lunchtime every day. We gradually increase the level of difficulty by making the phrases more similar and then more complex. Games can be used such as ‘Go Fish’, ‘Guess Who?’ and any other games which involve questions. Think about the interests of the student and what they would enjoy doing.
Slide 22-

Discourse level listening We begin reading simple picture story books and have the listener try to match the words with the text. This is very difficult initially but as the implant is mapped, and the sounds become clearer, it becomes easier. When I initially received my implant I could only hear the vowel sounds, then gradually the high frequencies and finally the whole word (at approx. 6 weeks post switch on). Audiobooks, Ted Talks, YouTube clips, TV shows – can all be used for Discourse level language activities – anything that engages the listener.
Slide 23-

Brain Training Learning to listen is quite different for children who are learning language compared to adult learners. The process however is similar. It takes a lot of work. During listening training ensure that the listener cannot see your mouth. Sit beside the child (on the side that you are training) and make sure they look straight ahead.
Slide 24-

The Issues People think that I can hear normally – the implant has ‘fixed’ the hearing. I still struggle in noisy situations, especially in a big group or where I can’t see people’s faces (camping). Some rooms have very poor acoustics. Think about the acoustics in your school rooms. Science and cooking rooms, with hard surfaces and floors, make listening very difficult. Soften the surfaces as much as you can. Cushions, curtains, felt on tables - anything to reduce the noise ‘bouncing’ around. The emotional issues of being deaf.
Slide 25-

Social and Emotional Issues This is a huge topic! Everyone has their own feelings about this. A person with a Cochlear Implant is still deaf. They are using technology to access sound. What happens when the technology doesn’t work? Expect the unexpected. Some people feel that they are part of the ‘hearing’ world. They have nothing to do with Deaf people. Some people feel that they are part of the ‘Deaf Community’ and learn to sign. Some people belong to both communities. Often the decision has been made for the child by the parents. Other issues can arise in regard to ‘deaf identity’ as the child becomes a teenager or young adult.
