I am a man who had surgery on only the tip of his chin with a twister. The asymmetry of the tip of his chin was stressful, so I decided to have the surgery. In fact, I still don't know if I did a good job. Currently, the swelling is almost gone except for the front chin. The bone at the tip of my chin seems to have been trimmed well, but I am stressed because it looks a bit unnatural due to the muscles. Yes.. haha the swelling is a bit uneven and the muscle is attached a little above the jawbone, so the fact that it looks like a double chin is the most stressful thing. When you look at it from the side, it looks like a bumpy and sloping chin. The incisions in the mouth are uncomfortable and I wear it every time I eat, and I can't even feel my front chin. There's almost nothing. I'm a little regretful that it hasn't come out in a satisfactory shape yet .
