In Asia, one of the most important factors in being physically attractive is to have aesthetically pleasing legs, which has made calf contouring surgery an issue nowadays. When one leg is abnormally changed because of various factors (e.g., iatrogenic causes, poliomyelitis, cerebral palsy, trauma, and tumor resection), the tissue atrophies. Such asymmetric calves can be corrected by various surgical methods.
Calf asymmetry is defined as a difference in the maximal circumference greater than 2.0 cm between both calves. From 2005 to 2012, the authors carried out calf contouring operations on 68 patients. For patients with mild or moderate asymmetry, selective neurectomy with or without liposuction was performed on the hypertrophic calf according to shape and severity. For patients with severe asymmetry, selective neurectomy with liposuction was performed for the hypertrophic calf, whereas the hypotrophic calf was treated with fat injection or silicone implantation.
At a minimum of 3 months' follow-up, the mild group patients had a size difference less than 0.5 cm. The moderate and severe asymmetry groups showed size differences less than 1.2 and 2.3 cm, respectively. No functional problems or major complications were shown. Minor complications included five cases of wound dehiscence, three cases of hematoma, and six cases of hypertrophic scar at the incision site.
Classifying patients into three groups according to the maximal circumferential difference between both legs and treating them separately using different surgical methods could significantly provide satisfying outcomes in both functional and aesthetic aspects.

在亚洲，拥有美观的腿部是吸引人的重要因素之一，这使得小腿塑形手术成为当今的热门话题。由于各种因素（如医源性原因、脊髓灰质炎、脑瘫、创伤和肿瘤切除）导致一条腿异常改变时，组织会萎缩。通过各种手术方法可以矫正这种不对称的小腿。
小腿不对称定义为双侧小腿最大周长差异大于 2.0cm。作者于 2005 年至 2012 年对 68 例患者进行了小腿塑形手术。对于轻度或中度不对称的患者，根据形状和严重程度，对肥大的小腿进行选择性神经切断术加或不加脂肪抽吸术。对于严重不对称的患者，对肥大的小腿进行选择性神经切断术加脂肪抽吸术，而对消瘦的小腿则采用脂肪注射或硅胶植入术。
在至少 3 个月的随访中，轻度组患者的大小差异小于 0.5cm。中度和重度不对称组的大小差异分别小于 1.2cm 和 2.3cm。无功能问题或重大并发症。轻微并发症包括 5 例伤口裂开、3 例血肿和 6 例切口部位肥厚性瘢痕。
根据双腿之间的最大周长差异将患者分为三组，并分别采用不同的手术方法进行治疗，可以在功能和美学方面显著提供满意的结果。
临床问题/证据水平：治疗，IV。
