The clinical outcome after fat grafting for facial rejuvenation and contouring can be less optimal because lack of standardized techniques is performed by the surgeon for the procedure. In this review, the author has tried to provide a rationalized approach to fat grafting for facial rejuvenation and contouring. The preferred donor sites include low abdomen and inner thigh especially in younger patients. Fat grafts should be harvested with low negative pressure via syringe liposuction technique to ensure the integrity as well as the optimal level of cellular function. Fat grafts should be processed with proper centrifugation that can reliably produce purified fat and concentrated growth factors and adipose-derived stem cells, all of which are beneficial to improve graft survival. Fat grafts should be placed after certain principles with gentle injection of small amount during the withdraw phase of each pass in multiple tissue planes and levels with multiple passes to ensure maximal contact of graft with vascularized tissue in the recipient site. The approach described in this review is supported by the most recent scientific studies and thus can likely provide a more predictable long-lasting result if performed properly.
由于外科医生在进行面部年轻化和轮廓塑形的脂肪移植手术时缺乏标准化技术，其临床效果可能不太理想。在这篇综述中，作者试图为面部年轻化和轮廓塑形的脂肪移植提供一种合理的方法。首选的供区包括下腹部和大腿内侧，尤其是年轻患者。应通过注射器吸脂技术以低负压采集脂肪移植体，以确保其完整性以及细胞功能的最佳水平。脂肪移植体应进行适当的离心处理，以可靠地产生纯化脂肪、浓缩生长因子和脂肪来源干细胞，所有这些都有利于提高移植体的存活率。脂肪移植体应按照一定原则放置，在每次进针的回撤阶段在多个组织平面和层次中轻柔地少量注射，并进行多次进针，以确保移植体与受区血管化组织的最大接触。本综述中描述的方法得到了最新科学研究的支持，因此如果操作得当，可能会提供更可预测的持久效果。
