Mandibular protrusion seems to be about osteotomy and then moving the mandible backwards to adjust its position. There is no danger. The incision is usually small or on the inside of the mouth, so don't worry about scars ~ if you want to do it, you can go to the Golden Plastic Surgery Center. Not a good Korean plastic surgery hospital. Dean is a senior plastic surgeon in Korea, and many people admire plastic surgery very much ~
