Kathy -
I had my BAHA surgery 14 months ago with only local anesthetic. My doc just shot lidocaine into my head. I didn't feel a thing.
My AN surgery wasn't painful - but it's definitely a much more intense surgery.
For the BAHA I had the choice of having local or general anesthetic, but was told that my doc does about 90% of them with local so I figured I'd choose that option.
I have to admit I was a little nervous about not being put to sleep, but I was so thrilled to finally be having the surgery that the nervousness was pretty minimal. My AN surgery was 9 months prior and I wasn't adjusting to SSD well at all
Some of the sounds during the surgery are a little "interesting" but I didn't find them disturbing. I could hear water running several times - which was actually my doc irrigating my head - and I also could hear the drill and feel a little pressure from it. Most of the time I was so engaged in talking to the nurse sitting next to my head that I didn't really pay attention to what the doctor was doing. And with all the drapes I had on me, I couldn't see what he was doing either.
Prior to the procedure my doc likened the sound of the drill to a trip to the dentist to have a cavity filled and he was correct.
I found the best part of having local anesthesia was not "recovering" from being knocked out. Nothing to wake up from, no nausea, etc. I could have literally walked out of the OR once the surgery was over, but they wouldn't let me. I did walk out of the hospital though; no wheelchair.
As far as pain post op, I took some extra strength Tylenol the afternoon of the procedure and the next morning; then nothing after that. Everyone's experience is different - including pain tolerance - but the surgery really is a piece of cake and generally not intensively painful.
If you have another questions, please feel free to ask me - or PM me, if you're more comfortable with that.
Best,
Jan
