Schematic representation of the effect of liposuction and fat grafting (lateral view). (A) Before the operation, the buttock shows a sagging appearance. Ptotic tissue can be seen at the infragluteal fold. (B) After the operation, the most prominent portion position was elevated from the lower half to the upper half of the gluteal area, and the supporting effect of the infragluteal region to the gluteal area was enhanced, achieving significant improvement of gluteal ptosis and a gluteal lifting effect.
