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.
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.
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.
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.
微自体脂肪移植（MAFT）-枪技术用于将小脂肪颗粒准确输送到不同部位的多个脂肪层。我们的研究介绍了使用 MAFT-枪技术进行全脸轮廓塑形的手术和临床结果。
自 2021 年 1 月至 2023 年 6 月，我院有 31 名健康参与者接受 MAFT-枪技术进行全脸容量增加术，纳入本研究。收集并分析不同面部部位脂肪移植量、并发症和满意度（%）的数据。
左右脸颊的平均脂肪移植量分别为 10.3±0.31ml 和 10.2±0.30ml。前额和太阳穴需要较低的脂肪量，分别为 9.8±0.23ml 和 4.5±0.21ml。鼻唇沟、泪槽和眶下区需要较小的脂肪量，分别为 2.2±0.11ml、1.9±0.10ml 和 1.4±0.11ml。鼻唇沟和泪槽的脂肪量在年轻人和老年人之间有显著差异。没有感染、坏死或血管损伤等并发症。随访结束时，26 名患者（83.9%）对手术后的效果表示满意。
MAFT-枪技术是一种安全有效的全脸自体脂肪移植技术。商用封闭系统处理器可作为脂肪处理的有效替代离心方法。该手术显著改善了面部凹陷，使患者即使在术后 12 个月也具有更吸引人且满意的外观。
