A few days ago, I finally found a hospital where I wanted to contour, and
 he explained it while watching CT. He said it would be effective, and the program cut it as expected, but
 it seems like it cuts too close to the nerve line for me who don't know.
 
The distance from the nerve line to the chin is 6.7, but you can remove about 6mm and you can do it safely
 . Old women who wonder if they are cutting too much to the extent that it will become a problem later, and what will happen even with a small shock.

This is a question I ask because I am so scared of plastic surgery, do you cut it close to the nerve line when removing the square jaw?
