Is this an invasive surgery? What about risk of infection? My surgeon told my parents many years ago that he would not correct my eyebrows again because it was too risky. He had already tried it twice. He had also operated on me as an infant to fill in the indentations on my forehead; my indentations went right back to the way they were. He operated on me again in 2007 using a new material (a type of medical cement I think) instead of bone and it stayed! So I'm thinking new medical procedures might make the type of thing I'm looking for a reality. By the way, every one of my failed surgeries occurred in the mid-late 90's.
