I thought I would share a little information on what a cochlear implant is for our family and friends that are curious. I have been reading about them and learning about them for awhile now, and they still confuse me. So I will do my best to describe it, but no promises that it will be easy to understand.
Laynie's surgery is next week (as long as she stays healthy... she just got a cold on Monday). She will have a CT scan first so the doctor can see where her facial nerve is. One of the big complications of this surgery is that her facial nerve can be damaged and it can cause facial paralysis. We love our little girl's big smile and we are really hoping a praying this does not happen, but realize it is a possibility. Also her inner ears are formed very differently because of her CHARGE syndrome, so it is going to be a lot more complicated than most cases. The other major complication is infection and meningitis. She will always be at a higher risk for meningitis after her surgery. It definitely scares us!!! And since the surgery is near her brain, the infection risk is very serious.
For the surgery, I think they will be shaving a little bit of her hair behind her ear and then making an incision behind her ear. They will drill a little hole in her skull and put a magnet right behind her ear (in her hair). They are planning on removing her ear drum to give them more room to operate because she does not need it. They fish a coil up in her inner ear into her cochlea. That will contain the electrodes that send the signal to the brain. This will be the part that the doctor is a little concerned about. The more electrodes that goes into the cochlea, the better the results. He said that Laynie has a very small cochlea so he doesn't know how many electrodes he will be able to fit in. So we will just have to wait and see. Then she has to wait 2 weeks for it all to heal before it gets activated. That will be such an exciting day:)
The diagram above shows how a cochlear implant works. It still confuses me, so it can describe it much better than I can!!!
Laynie is getting a new type of implant called the Neptune. It is the first cochlear implant that is 100% water proof (not that she will be swimming) but we really liked it because it is worn completely off the ear. It just has the headpiece that will magnetize to the magnet inside her head. It also has a microphone on it. And then a cord will connect the headpiece to the processor. The processor can be worn on an arm band or clip on to a shirt, etc.... We are really excited about this option so we don't have to worry about putting something back on her ears 100 times a day.
I am sure we will learn so much in the next few weeks and we will become pros, but it seems very overwhelming right now. I hope I explained everything right. I remember when they told us we would be pros with the trach and I laughed. You learn quick when it comes to helping your child!!!! We are excited about this new adventure for Laynie, but still are very nervous!!!
