What is the difference between “Chinese face transplant” and “face transplant” in other countries So far, foreign countries have adopted the “allogeneic face transplant” technique. “Chinese face transplantation is done entirely with the patient’s own tissue. After “allogeneic face transplantation”, the patient has to face various problems, suffer from rejection, the transplant recipient has to take medication day by day, face many risks such as infection and tumor, and the financial burden is too heavy. “Allogeneic face transplant patients even have to face ethical issues. The first international allogeneic hand transplant patient was disgusted with the idea of having someone else’s hand on his or her hand. It is hard to imagine how many psychological hurdles one has to face when another person’s face is on one’s own face. Because “allogeneic face transplantation” is subject to rejection, the success rate is currently not high, while the success rate of “Chinese face transplantation” is relatively high. All disfigured people can be full face “face”? “Chinese face” technology is now mature, the country’s many hospitals ready to join forces to promote. However, for the access threshold, plastic surgery experts said they will be assessed, classified and graded for surgery. “The actual fact is that there is no pattern to the burn situation, different patients have different situations. Considering safety, different surgeries will be selected for patients. “Li Qingfeng pointed out that most of the burns on the face, especially the central five senses, including the eyes, nose, mouth and other disfigurement will be considered full face replacement surgery or local autologous face replacement. Its cost is far less than resuscitation and allograft face replacement surgery at the time of the burn. “Chinese face replacement” is how to carry out the “face” with their own tissue, the first problem encountered is that experts have never seen the 22-year-old girl’s face before disfigurement. So, the three-dimensional printer first role, the face contour and disfigured organ range and other information scanned into the computer, with data analysis of the girl’s personalized features before disfigurement, and then three-dimensional printing technology to print out a three-dimensional face model. Then, the specialist began to reconstruct the face, and the first operation was to build a blood supply for the girl’s new face. The blood vessels for the new face came from the leg. A section of blood vessel was removed from the patient’s leg, which carried a fascial tissue flap that nourished the blood vessel. Through microsurgical techniques, the fascial tissue flap that nourished the blood vessel was placed over the blood vessel in the head and neck, and the network of blood vessels was implanted under the skin of the chest. Immediately afterwards, a second procedure is performed: the skin of the new face is cultured. Specialists implanted skin expanders under the skin of the chest, then periodically injected water into the expanders as the skin grew larger and thinner, and the new skin grew heavier and paler. “The skin needed to replace the face was as big as half a basketball.” Li Qingfeng said, the new skin in the chest “expansion” takes an average of 4-6 months, the time required varies from person to person, in the chest new growth of the new face skin is very heavy, a full two or three pounds. But the implanted blood vessels may not be enough, so the specialist then extracts a small amount of bone marrow from the body, isolates the stem cell component, and injects the stem cells into the “new face skin” on the chest, further regenerating the expanded skin tissue and thickening the skin. The third procedure is to build the facial organ on the skin of the chest. Combined with a 3D model, the specialist sculpted and constructed a 3D scaffold for the nose and maxilla from the girl’s own cartilage, which was then implanted under the skin of the new face. Once again, a miracle occurred, and through vascular growth and healing, a new face emerged on the chest. In the fourth and final procedure, the face transplant, the specialist “transferred” the new face from the chest to the disfigured face along the blood vessels in the head and neck. Eight or nine months later, all the hard work and waiting had not been in vain. As time passed, all the skin of the girl’s new face survived, and the expression muscles of the original face quickly fused with the new face, and expressions miraculously appeared. Earlier this year, the girl saw a brand new self in the mirror. And that new skin on her chest was transplanted to her face leaving only scars, without any other damage to her body. It is said that in a year or two, her expression will be more natural.
