Rejuvenation of the dorsal surface of the hand for various conditions, such as cutaneous dyschromia, fine wrinkling, skin laxity, visible extensor tendons, and varicosities appear vital to prevent wrist and digit flexion resulting from hiding of the aged appearance of the hand. Numerous fillers have been applied to re-contour the aging dorsal surface of the hand and the results were variable. The micro-autologous fat transplantation (MAFT) technique, proposed by Lin et al. in 2006, has demonstrated its feasibility in facial rejuvenation. In this study, we applied the MAFT technique for the rejuvenation of the dorsal portion of the hand.
MAFT was performed in 68 female patients. Fat was harvested by performing liposuction, processed, and refined by centrifugation. Purified fat was micro-transplanted to the dorsal surface of the hand in parcels of small volume.
The mean age of the patients was 56 years (range, 38-70 years). MAFT was completed in 72 min, on average. The average amount of delivered fat was 13.9 and 13.8 mL for the right and left hands, respectively. The mean follow-up period was 32 months (range, 10-64 months). The 5-point Likert scale revealed that 58.8% of patients were very satisfied and 39.7% were satisfied about their outcome.
MAFT has changed the concept of fat grafting, from an operation with unpredictable clinical results to an easy and reliable procedure. MAFT demonstrated high patient satisfaction with long-term results and is an effective approach to rejuvenate the dorsal surface of the hand.
对手背进行年轻化治疗以改善各种状况，如皮肤色素沉着、细纹、皮肤松弛、可见的伸肌腱和静脉曲张，对于防止因手部显老外观而导致的手腕和手指屈曲显得至关重要。众多填充剂已被用于重塑老化的手背外形，但其效果各异。林等人于2006年提出的微量自体脂肪移植（MAFT）技术，已在面部年轻化治疗中证明了其可行性。在本研究中，我们将MAFT技术应用于手部背侧的年轻化治疗。
对68例女性患者实施MAFT。通过吸脂获取脂肪，经离心处理和提纯。将提纯后的脂肪以小体积包裹的形式微量移植到手背。
患者的平均年龄为56岁（范围为38 - 70岁）。MAFT平均在72分钟内完成。右手和左手移植的平均脂肪量分别为13.9 mL和13.8 mL。平均随访期为32个月（范围为10 - 64个月）。采用5分制李克特量表显示，58.8%的患者对治疗结果非常满意，39.7%的患者满意。
MAFT改变了脂肪移植的概念，从一种临床结果不可预测的手术转变为一种简便可靠的操作。MAFT显示出患者对长期效果的高度满意度，是手部背侧年轻化的有效方法。
