I am very concerned about the implants. I support it. I have some questions that might be important to you.
(1) How long will it be last?
(2) Does it required you to replace the channel wires every couple of years (i.e. 10 years)?
(3) What kind of wires does it have for the cochlear? i.e. aluminum or stainless metal. Does it covered with coat of plastic to prevent rust?
(5) Will it able to upgrade the hearing aid device for your same wires in your cochlear?
(6) Do the cochlears ever grow when the kids get older?
Good questions!
The answers are as follows:
1) Even implanted young, they can last your entire life. They are built to last and they are built with excess capacity so you never really reach a limit with them. Given how fast they are improving them and if you probably younger than 60, then it is possible one will get a replacement with these improvements (i.e., better sound quality and etc). I was told given my age (47) that I would probably get a replacement at some point down the road. I will deal with that when I get there. You don't have to but the option will probably be there. Once you have a CI done, any future surgery is a "walk in the park" because all the hard works has already been done.
2) I assume you mean the one's inside your head then see #1. No replacement for channel wires except to replace the whole thing due to implant failures. It does happen but very rarely and as I mentioned before it is not complicated as the original surgery.
3) I'm not sure of the metal but it is my understanding that is a non issue as they don't rust. There are people out there who have used them for two decades with nary a problem.
Er...you skipped 4 and I will continue to sequentially follow with four which answers question 5 and 5 for 6.
4) Yes, you will be able to upgrade the hearing device itself every so often especially to take advantage of better software and hardward (outside part). The implanted part simply stays put and not touched except for failures or replacement at some far future point if it were done.
5) It is my understanding that the size of children's head 1+ years old is already at a good percentage of their adult size. I think for a 2 year old it is 80% of the size of an adult. So, there is not as much growth with the skull as the rest of the body. This is good for the implant part that is seated on the skull. Where they have to allow for is the "channel wire" going into the cochlea itself. I believe they have some excess or slack to allow for skull growth when one reaches adulthood. There are some people out there who are adults but received their implant while young and it is working just fine.
I hope that helps...
