Silicon capsule prosthesis, free transplantation of autologous dermal-adipose tissue fascia flap, pedicled dermal-adipose flap filling, latissimus dorsi-dermal composite tissue island flap, rectus abdominis dermal-adipose muscle flap transfer, etc. Among them, silicon capsule prosthesis implantation is the most commonly used. But I personally think that autologous fat is safer and more adaptable to your body.
