First of all, we should know that mandibular angle plastic surgery is a professional orthopedic surgery, and the surgical process is quite detailed. Because the muscle tissue in mandible is closely connected with periosteum, it will recover naturally after operation, and the skin will not sag due to operation. Human skin is very elastic and tough, and mandibular angle plastic surgery only removes a small part of bones, which has no effect on skin firmness.

Secondly, after mandibular angle plastic surgery, the face will be pressed and bandaged to promote the firmness and recovery of facial skin, and the face will become firm and natural after surgery. Over time, the facial skin clings to the mandible, so there will never be a case of facial collapse after getting old.
