Nowadays, there is an increasing demand for contouring of the entire lower leg, in addition to corrections at the level of the muscle only. Accordingly, it becomes advantageous to use fat tissue for this purpose, for its availability in high quantities, potential for its easy implantation in all leg parts, biological compatibility, low antigen potential, and minimal donor morbidity.
Forty-eight female patients, aged 20-54 (47.1 % younger than 35 and 52.9 % older than 35), underwent lower leg augmentation with autologous fat. We compared pre- and 1, 3, and 6 months postoperative morphological and volumetric characteristics of the recipient region by circumferential measuring of particular parts of the lower legs and evaluating the presence of live transplanted fat by MRI and histological examination.
The augmentation of certain circumferences of the lower leg at the 6-month follow-up examination is significantly related to preoperative circumference as well as to the quantity of infiltrated fat. Therefore, lower the baseline circumference, the greater the augmentation, and the greater the quantity of infiltrated fat, the greater the augmentation.
Ensuring adequate technique in the transfer of fat tissue from the donor region to the recipient region of the lower leg is definitely the least invasive method of lower leg contouring. For patients with muscle dystrophies or those with injuries, this technique could become the first choice for its minimal complications. The simplicity of the procedure invites its wide application in plastic surgery.

如今，除了仅在肌肉层面进行矫正外，对整个小腿塑形的需求日益增加。因此，使用脂肪组织来达到这一目的具有诸多优势，因为其来源丰富，易于植入小腿的各个部位，具有生物相容性、低抗原性以及供区并发症极少。
48名年龄在20至54岁之间的女性患者（47.1%年龄小于35岁，52.9%年龄大于35岁）接受了自体脂肪小腿增粗术。我们通过测量小腿特定部位的周长，并通过MRI和组织学检查评估移植存活脂肪的存在情况，比较了术前以及术后1、3和6个月受体区域的形态和容积特征。
在6个月的随访检查中，小腿特定周长的增加与术前周长以及注入脂肪的量显著相关。因此，基线周长越低，增加幅度越大；注入脂肪量越大，增加幅度也越大。
确保将脂肪组织从供区转移至小腿受体区的技术得当，绝对是小腿塑形的侵入性最小的方法。对于患有肌肉萎缩症或受伤的患者，由于其并发症极少，该技术可能成为首选。该手术操作简便，促使其在整形手术中得到广泛应用。
