The worlds first face transplant took place a mere eight years ago, but already the field is advancing at a rapid pace: surgeons in countries including France, China, and the US have all performed these intensive procedures with successful results. And now, the US government is getting ready to regulate the field of face and hand transplants the same way they do with conventional organ transplants. Right now, face and hand transplants are so rare that the processes — from donation to surgery to post-transplant monitoring — are largely overseen by hospitals and doctors themselves.
