FAQ's

Q: What is a cochlear implant?
A: A cochlear implant is a surgically implanted device that directly stimulates to cochlea to transmit sound messages to the brain. The internal device is made up of an electrode array that goes inside the cochlea, and a receiver/stimulator. The receiver/stimulator contains a magnet so that the external processor can be hooked up to it.
The external part of the cochlear implant is a microphone (attached to the processor) a processor (either body worn or behind the ear) and a magnet that attaches to the side of the head to transmit the messages to the stimulator and then on to the brain.

Q: What kind of implant does David have?
A: David has the Cochlear Nucleus Freedom. More information on this particular implant can be found at www.cochlearamericas.com

Q: Why did David only have one side done?
A: David still gets pretty good benefit from his hearing aid. When he was going through the testing for the implant, the specialists talked to us about only doing the right side, where David's hearing is worse.

Q: Will David be able to get the other side done?
A: After he goes through the mapping process and speech therapy, if David likes the implant and what it does for him, he can choose to have the other side implanted as well. This would not happen until he's had his current implant for at least a year.

Q: When will the device be activated
A: Sometime around a month - 6 weeks after the surgery, we will go in for the initial mapping session

Q: What is mapping?
A: Mapping is the programming of the processor. It will adjust volume, and have different programs for different environments. It will need to be adjusted several times in the first few months so that David will get the most benefit from the device.

Q: Does it come off?
A: The external part of the implant is worn just like a hearing aid (David is getting the behind the ear processor) It comes off just like a hearing aid too. At night, so he can sleep, and for showering, swimming, and any water activities.

Q: Does it use batteries?
A: With the Freedom, David will have the option of using two different kinds of batteries. Rechargeable lithium ion batteries, and disposable batteries. The lithium ion batteries are a more cost effective method :)
