Facial volume loss is an important component of facial aging and tends to present at an earlier age than other aspects of aging. Several surgical and nonsurgical products and techniques are available to replace volume loss associated with aging. One surgical technique uses a patient's fat cells to replace or augment volume deficiency. Poly-L-lactic acid (PLLA) injection is a nonsurgical option. This article compares these 2 volume augmentation procedures and discusses characteristics of facial aging, the consultation process involved in assessing individual volume loss, procedure details of autologous fat grafting and PLLA injection, the decision of PLLA versus autologous fat, and patient outcomes.
面部容量减少是面部衰老的一个重要组成部分，且往往比衰老的其他方面更早出现。有几种外科和非手术产品及技术可用于替代与衰老相关的容量减少。一种外科技术是利用患者自身的脂肪细胞来替代或增加容量不足。聚左旋乳酸（PLLA）注射是一种非手术选择。本文比较了这两种容量增加手术，并讨论了面部衰老的特征、评估个体容量减少所涉及的咨询过程、自体脂肪移植和PLLA注射的手术细节、PLLA与自体脂肪的抉择以及患者的治疗效果。
