Hi Cheryl,
I had my lip split but just to the crease in my chin. That was the quickest part of my anatomy to heal and you need to look really look to see the scar. They did take a small amount of bone during surgery but don�t know exactly where from and it was not invasive. I can ask at my next routine visit. This was for testing only and I remember the pathology took the longest to come back. It was explained that it gets crushed to test. I was happy to get the all clear on that around one week later while recovering in hospital.
Wishing you all the very best with your surgery.
Gabriele
