BAHA = Bone Attached Hearing Aide
I just had the surgery 3 days ago, but still don't really get the scientific explanation of how it works (hell, I'm an accountant - I know NOTHING about medicine
)
Anyway, I'll explain it this way - pardon my rudimentary description, please - this is the way another BAHA patient described his surgery to me before I had mine and although I was wide awake the entire time, I didn't ask the doc to do a play by play of the action LOL. I plan to get more details from the doc when I go for my post op appt. next week. I'm thinking if I had the surgery, the least I can do is find out exactly how it was done.
In a nutshell, the doc basically lifts up a layer of your scalp, inserts a titanium plate, and attaches a "fixture" to your skull (aka "bone"). I say attaches, but the doc pretty much drills a hole in your skull and inserts the fixture. The fixture lies flush with your skin - doesn't stick out - and is about the size of the tip of your little finger. After the fixture has calcified to the bone, it is strong enough to hold an "abutment" which you attach the processor or "device" to. The abutment is sometimes referred to as a screw. The processor or device is a tiny hearing aide (approximately the size of the your thumb if you measure from the tip to the knuckle).
In contrast to a conventional hearing aide, or a Cros, or a TransEar the device doesn't go inside your hear; it attaches directly to your skull. The bone actually helps the sound travel somehow - I'm not at all sure how, I just know that it does.
I think I'm in over my head here - someone who understands medical stuff needs to help me out. Lori67? Sam Rush?
