Lacey -
the following link explains a lot about the BAHA; my brother found it and emailed it to me.
http://www.umm.edu/otolaryngology/baha.htmThe processor is actually what they call the tiny hearing aid. And it truly is a hearing aid - it contains a tiny microphone and even takes hearing aid batteries. I didn't realize it until I got mine, but processors come in left side and right side. The processor is also sometimes referred to as the "device".
The titanium fixture which is implanted into the head is sometimes referred to as a screw, but I find that term a little misleading because the processor doesn't screw on - it snaps on. Also, the doctor doesn't screw it into your skull, he drills a hole (yes, it's a real drill) and implants it. He doesn't use a screwdriver! So if anyone had thought to ask me, I'd have called it a snap
The abutment is the part that is sticking out of the processor - it connects the processor to the fixture.
Generally there is a waiting period between the implant surgery and when you can wear your processor, because the fixture has to calcify to the bone. My doctor makes patients wait 3 months because he feels attaching the processor any earlier can cause "torque". Torque was explained to me as the fixture possibly moving around in the hole in my head because of the motion of attaching and detaching the processor. Apparently waiting 3 months greatly eliminates torque.
The audiologist did tell me not to sleep with the processor attached. You also cannot get it wet - or you will fry the battery. So while you can obviously shower, swim, etc., with the fixture in your head, you should never do so with the processor attached.
The fixture is located on the side of your head so if you sleep on your back it won't bother you. I sleep on my side - on my bad ear - and the fixture doesn't bother me because it is flush with my head - it only sticks out a tiny bit. Plus, as you say, having a numb head is also valuable
And that concludes BAHA Lingo Class 101. Pop quiz tomorrow
