摘要
目的通过对乳房下皱襞相关组织结构的大体解剖和组织学研究,进一步明确乳房下皱襞的组织学和解剖结构。方法采用新鲜成年女性尸体行解剖研究,并分别于乳房上缘、乳晕上缘、乳房下皱襞及乳房下皱襞下方4cm处取材,制作HE染色及改良Gomori′s trichrome染色切片,并进行图像分析。结果共研究乳房20只,在乳房下皱襞组可见皮肤真皮层内红色的纤维组织排列平行于乳房下皱襞的长轴,胶原纤维的断面较少,各组的胶原纤维相对含量无明显差异。结论乳房下皱襞区域无下皱襞韧带结构,真皮内胶原纤维的密度和其他三组相比,无明显差别。
Objective To study the anatomy and histology of the inframammary fold and make progress in understanding this structure. Methods Using fresh adult female cadavers to make some dissection study. The skin tissue sample was taken respectively from the upper female breast, the upper areola of nipple, the female inframammary fold and the female lower 4 cm inframammary fold. HE stained and improved Gomori＇s trichrome stain slices were processed and image analysis was performed. Results Red collagen fibers arrayed parallel to the long axis of the inframammary fold in the dermis and had less break end in the inframammary fold group compared with other groups, The relative content of collagen fibers has no significant difference among each group. Conclusion No inframammary crease ligament exists in the inframammary fold area, and the density of the collagen fibers does not increase in the inframammary fold group compared with other groups.
