Reconstruction with the oblique sigmoid island flap, which we contrived as a subcutaneous pedicle flap, is performed as follows: the small triangular skin flaps, about 1 to 2 mm in length on each side, are excised from both sides of a round defect following tumor excision in a direction corresponding to the wrinkle line, and a subcutaneous island flap which has a width equal to the defect and has shifted about half the distance of the defective area in parallel with the wrinkle line is advanced and sutured. Our technique is thought to be highly effective from a cosmetic point of view because reconstruction of the defects following excision of small tumors that occur in sites with delicate eminence, such as the area between the inner canthal region and the cheek, the site along the nasolabial fold, and around the alae, often tends to fail to achieve cosmetically good results when conventional local skin flaps are used.
采用我们设计的皮下蒂斜乙状结肠岛状皮瓣进行重建，具体操作如下：在肿瘤切除后，从圆形缺损两侧沿皱纹线方向切除约1至2毫米长的小三角形皮瓣，然后推进并缝合一个宽度与缺损相等、沿皱纹线平行移位约缺损区域一半距离的皮下岛状皮瓣。我们的技术从美容角度来看被认为非常有效，因为在如内眦区域与脸颊之间、鼻唇沟沿线以及鼻翼周围等精细突出部位出现的小肿瘤切除后，使用传统局部皮瓣重建缺损往往难以达到良好的美容效果。
