This is Xiaolin, and according to Reuters, he's growing a new nose on his forehead. He lost his old nose due to a traffic accident infecting the cartilage.
The process works by placing a skin tissue expander onto his forehead, cutting it into the shape of a nose, and then using cartilage from his ribs. It uses a similar technique to that of a breast implant.
Local media reports that his new forehead nose is in good shape and will be back where it belongs in the center of his face in no time.
Looking, uh, good.
