Introduction
The micro-autologous fat transplantation (MAFT)-gun technique is applied to accurately deliver small fat parcels to multiple fat layers across different sites. Our study presents the surgical and clinical outcomes of using the MAFT-gun technique for full-face contouring.
Methods
From January 2021 to June 2023, 31 healthy participants undergoing full-face volumization using the MAFT-gun technique at our hospital were included in this study. Data on fat volume grafted at different facial sites, complications, and satisfaction rates (%) were collected and analyzed.
Results
The average fat volumes grafted over the left and right cheeks were 10.3 ± 0.31 ml and 10.2 ± 0.30 ml, respectively. The forehead and temples required lower fat volumes of 9.8 ± 0.23 ml and 4.5 ± 0.21 ml, respectively. Small fat volumes were required for the nasolabial fold, the tear trough, and the infraorbital areas, with 2.2 ± 0.11 ml, 1.9 ± 0.10 ml, and 1.4 ± 0.11 ml, respectively. The fat volumes for the nasolabial fold and the tear trough were significantly different between young and old people. No complications, including infection, necrosis, or vascular injury, were noted. At the end of the follow-up, 26 patients (83.9%) expressed their satisfaction after the procedure.
Conclusion
The MAFT-gun technique is safe and effective for full-face autologous fat grafting. Commercial closed-system processors could be an effective alternative to centrifugation for fat processing. The procedure significantly improved facial hollowness and resulted in a more attractive and satisfied appearance to people even after 12 months postoperatively.
