In the past those crazy surgeons would have to take multiple pieces of skin and graft them onto some poor buggers face bit by bit. Like playing with Mr Potato-Man only you get a lot more gunk on your fingers.
But wait, new methods mean they've successfully pulled one giant bit of skin from some guys back and stuck it across the entirity of the poor buggers face.
im not sure which one is better......i do like the top of his head in the after pic where his new face just stops and theres a big ridge of skin going onto his scalp
