Frontal fullness in Asians is often considered to indicate one's public popularity and leadership skills. Numerous materials and techniques have been applied clinically to recontour or volumize the frontal area, with variable results. The micro-autologous fat transplantation (MAFT) technique proposed by Lin et al. (2nd academic congress of Taiwan Cosmetic Association Taipei, Taiwan) in 2007 has demonstrated its feasibility in facial rejuvenation. In the present study, we used an innovative instrument to apply the MAFT technique to frontal augmentation with fat grafting and reported the results.
MAFT was performed on 178 patients (167 female, 11 male) during a 5-year period starting in January 2010. Fat was harvested by liposuction, processed and refined by centrifugation at 1200×g for 3 min. The purified fat was micro-transplanted for frontal contouring with the assistance of an instrument, the MAFT-GUN. The patients were followed up regularly, and photographs were taken for comparison.
On average, the MAFT procedure took 52 min to complete. The average amount of delivered fat was 10.2 mL. The follow-up period was 34 months on average. No complications, including neurovascular injury, skin necrosis, abscess, nodulation, calcification or irregularity, were noted. A patient-rated satisfaction 5-point Likert scale demonstrated that 83.1% of all patients had favorable results (48.3% were satisfied, and 34.8% were very satisfied).
The concept and technique of MAFT has changed fat grafting from an operation with unpredictable clinical results to an easy, reliable and consistent procedure. Furthermore, the use of a precisely controlled instrument enabled surgeons to perform highly accurate micro-fat grafting. In comparison with other strategies for volume restoration, the MAFT procedure demonstrated high patient satisfaction with the long-term results. Therefore, the use of MAFT as an alternative approach to forehead contouring and volumizing was addressed.

在亚洲人眼中，额头饱满通常表示此人受欢迎且具有领导能力。为了重塑或填充额头，人们尝试了多种材料和技术，但结果不一。2007 年，林等学者在台湾美容医学医学会第二届学术会议（中国台湾台北）上提出的微自体脂肪移植（MAFT）技术在面部年轻化中已得到证实。本研究创新性地采用仪器辅助进行 MAFT 脂肪移植，以达到丰额效果，现将结果报道如下。
自 2010 年 1 月开始，我们采用 MAFT 技术对 178 例患者（167 例女性，11 例男性）进行治疗，为期 5 年。通过吸脂术获取脂肪，1200×g 离心 3min 以获得纯净脂肪。采用 MAFT-GUN 仪器辅助微移植以重塑额头轮廓。定期对患者进行随访并拍照比较。
平均而言，MAFT 手术耗时 52min，平均移植脂肪量为 10.2mL，平均随访时间为 34 个月。所有患者均未出现神经血管损伤、皮肤坏死、脓肿、结节、钙化或畸形等并发症。采用患者自评的 5 分制满意度量表，83.1%的患者（48.3%满意，34.8%非常满意）对治疗效果表示满意。
MAFT 的理念和技术使脂肪移植术从结果不可预测的手术转变为一种简单、可靠、一致的方法。此外，使用精确控制的仪器可使外科医生进行更精准的微脂肪移植。与其他体积恢复策略相比，MAFT 具有更高的患者满意度和长期效果。因此，MAFT 可作为丰额和填充的替代方法。
