When viewed from the front, the chin is very wide and angular. When I looked into square jaw surgery behind the ears, I found that it was effective on the side but not on the front. There is also a method of cutting the cortex behind the ear for square jaw surgery, but wouldn't that have any effect on the frontal aspect? I had no intention of touching the bone, but this time I made up my mind, and I don't want to do the square jaw surgery, which involves making an incision inside the mouth, because I'm scared.
