Hello, the current "mandibular angle plastic surgery" can make the contour curve of mandibular angle soft and smooth. Can effectively change the "square face". However, you must first determine what caused your square face before you can change it. If the mandibular angle is too large, it needs to be osteotomy through mandibular angle plastic surgery. If the masseter muscle is too large, it is necessary to remove part of the masseter muscle or make the masseter muscle atrophy by face-lifting needle. If you want to do mandibular angle plastic surgery, you must come to New Tirana Plastic Surgery Hospital in Korea.
