以肿瘤和乳头为中心、以安全边界或 3 0cm为半径分别画圆 ,沿两圆边作两个“S”状纵切口线 ,上、下两端相交并位于锁骨及肋弓中 1/3段 ,术后形成典型的“S”形缝合切口。结果治疗乳腺癌 68例 ,全部Ⅰ期缝合 ,无患肢水肿及功能受限 ;2例出现皮瓣束状区域坏死 ,1例皮下积血 ;均在术后 3～ 4d开始辅助治疗。初步研究结果提示 ,通过改变切口走向可以更多的节省皮肤 ,预防并发症 ,提高生存质量并为提高治愈率创造了条件 Tumor and nipple as the center, the safety margin or 30cm radius respectively draw a circle, along the two round edges for two “S” shaped longitudinal incision line, the upper and lower ends intersect and located in the clavicle and rib arch 1/3 Segment, after surgery to form a typical “S” shaped incision. Results 68 cases of breast cancer, all Ⅰ suture, no limb edema and functional limitations; 2 cases of flap necrosis occurred in the skin, 1 case of subcutaneous hematoma; all 3 to 4 days after the start of adjuvant therapy. Preliminary findings suggest that by changing the direction of incision can save more skin, prevent complications, improve the quality of life and to improve the cure rate
