Abstract：
Dorsal contour deformity presents with different manifestations in each part of the back, such as back rolls, iliac crest deposit, and buffalo hump. However, scant current literature exists on the anatomical basis of dorsal contour deformity. The aim of this study was to better understand the anatomical characteristics of the back, and to propose evidence-based zoning principles for liposuction-assisted back contouring.
A total of 12 fresh cadavers were dissected for observation of each hierarchy in the vertical order (skin to deep fascia) and transverse comparison of the superficial fascial system (SFS) in the scapular-infrascapular-lumbar triangle region. Full-dorsum vectorial sections were used for the study of suprascapular fat deposits.
The SFS acts as a bridge connecting all levels of the dorsal subcutaneous tissue. Macroscopically, it is denser in the scapular and lumbar triangle regions and looser in the infrascapular region; microscopically, the ultrastructure of the retinaculum cutis consists of loose interlobular fascia and stiff functional fascia.
The regional variation pattern of the SFS in the back was consistent with observed back contour deformities in Asian female patients. A better understanding of the topographic anatomy of the back applied to evidenced zoning is the basis for improving surgical precision and avoiding dorsal contour deformity.

摘要：
背景：背部轮廓畸形在背部的每个部位表现不同，如后卷，髂嵴存款,还有水牛驼峰.然而,目前很少有文献在背侧轮廓畸形的解剖学基础上存在。这项研究的目的是更好地了解背部的解剖特征，为了提出基于证据的分区原则抽脂辅助背部轮廓。
方法：共解剖了12具新鲜尸体，以垂直顺序（皮肤到深筋膜）观察每个层次，并横向比较肩胛骨下腰椎三角区域的浅筋膜系统（SFS）。全背矢量切片用于研究肩胛骨上脂肪沉积。
结果：SFS充当连接背部皮下组织所有水平的桥梁。宏观上,它在肩胛骨和腰椎三角形区域更密集，在肩胛骨下区域更松散，在微观上，蒂支持带的超微结构由疏松的小叶间筋膜和僵硬的功能性筋膜组成。
结论：背部SFS的区域变异模式与亚洲女性观察到的背部轮廓畸形一致。更好地了解应用于证据分区的背部地形解剖是提高手术精度和避免背部轮廓畸形的基础。
