Autologous fat grafting is an aesthetic and reconstructive procedure in which an individual's own fat is harvested and injected into the soft tissues to correct contour and other abnormalities. Fat graft is considered the ideal soft tissue filler for its biocompatibility, lack of immunogenicity, and availability. The entire procedure of harvesting, processing, and transfer of fat graft affects fat graft take and effectiveness of fat grafting. This article will focus on the most common methods of fat graft processing, including centrifugation, cotton gauze rolling, sedimentation, and filtration/washing. The fragility of the harvested adipocytes makes the technique of fat graft processing of utmost importance, as blood and other unnecessary cellular fragments are removed. Each fat graft processing method has its own merits and shortcomings; however, due to a lack of well-defined prospective studies, there is no evidence to support one processing method as superior to another.
自体脂肪移植是一种美容和重建手术，在该手术中，个体自身的脂肪被采集并注入软组织，以矫正轮廓和其他异常情况。脂肪移植因其生物相容性、缺乏免疫原性和可得性而被认为是理想的软组织填充剂。脂肪移植的采集、处理和转移的整个过程会影响脂肪移植的成活率和脂肪移植的效果。本文将重点介绍最常见的脂肪移植处理方法，包括离心、纱布滚动、沉淀和过滤/冲洗。采集的脂肪细胞的脆弱性使得脂肪移植处理技术至关重要，因为血液和其他不必要的细胞碎片会被去除。每种脂肪移植处理方法都有其自身的优缺点；然而，由于缺乏明确的前瞻性研究，没有证据支持一种处理方法优于另一种。
