What is the method to correct facial/skull asymmetry? Jaw surgery or implants? (photos)

The left side of my face/skull is noticeable bigger than my right. My ear is pulled back on the smaller side which is less of an issue but the backside of my head especially lacks a lot of volume. Every feature on the right side of my face/skull seems to be smaller. I have looked into facial/skulll implant but also jaw surgery.
