Holey Skull

Went back to the surgeon so he could check his handiwork after 6 months. He said it was a big hole that has healed well and there is no further action required. He did checkout a few other watch list spots and applied a ray gun to them which emitted a cold ray that freezes the skin and any marks that might be there.  I would like to find a qualified dermatologist in the area who might do some ultra freeze themselves rather than going to the surgeon.
