The world's first partial face transplant on a living human was carried out on Nov. 27, 2005 by Professor Jean-Michel Dubernard, a plastic and microsurgeon in Amiens, France. Isabelle Dinoire underwent surgery to replace her original face that had been ravaged by her dog. A triangle of face tissue from a brain-dead human's nose and mouth was grafted onto the patient. In April, 2006, the Xijing military hospital in Xian, China carried out a similar operation, transplanting the cheek, upper lip, and nose of Li Guoxing, who was mauled by an Asiatic black bear while protecting his sheep.
