Face transplant. Conceptual computer artwork of a woman receiving a new face. Transplanting faces requires advanced microsurgical techniques to connect the numerous muscles, blood vessels and nerves of the new face to the patient. The donor face would come from a dead person. The technique could help those whose faces have been disfigured by disease or accidents such as burns. One major problem is the possible rejection of the new face by the patient's immune system. There are also psychiatric and ethical problems. Experimental transplants have already been carried out on dead bodies, which showed that the recipient rarely looks like the donor.
