Assessing facial fat volume at 6 months after structural fat grafting / 中国组织工程研究

ABSTRACT

BACKGROUND: With the increasing pursuit of beauty, facial cosmetics have become popular, and thereupon various cosmetic methods and surgical methods have emerged. However, high costs, large trauma, slow recovery, permanent scars and even scar hypertrophy can result from these cosmetic surgeries. Transplantation is a relatively new method for facial cosmetics, and the choice of graft is crucial for cosmetic effects. OBJECTIVE: To evaluate the curative effect of facial rejuvenation surgery with structural fat grafting. METHODS: From May 2016 to May 2017, 21 cases of facial rejuvenation were selected. All subjects were assessed for donor sites and affected areas by combining various factors. Fat tissues were isolated from the donor site, and implanted into the affected area after sediment and grease removal. Patient satisfaction and the severity of facial wrinkles were scored through a survey questionnaire. At 6 months after transplantation, the number of request to replenish injections and number of complication cases were statistically recorded. The volume of facial fat tissues in the affected area was calculated before and after transplantation. RESULTS AND CONCLUSION: Two subjects required re-transplantation during the 6-month postoperative follow-up. Facial capacity, depression, and static patterns of all subjects were well improved after one or two autologous fat transplantations. The average satisfaction score on fat transplantation for all the subjects was 8.47±0.43. The volume of facial fat tissues at 6 months after transplantation was significantly increased compared with that before operation (P < 0.05). The postoperative severity of facial wrinkles was significantly lower than before operation (P < 0.05). Only three subjects had complications within 6 months after transplantation, including one case of infection, one of liquefaction and one of fat embolism. V-Line liquid lift with structural fat grafting can effectively improve facial relaxation, sagging and other issues, with a good upgrade of facial rejuvenation effect.
