Abstract

Poly-L-lactic acid (PLLA) is a synthetic biologic polymer that is suspended in solution and can be injected for soft-tissue augmentation. The most common adverse events generally are transient in nature, such as swelling, tenderness, pain, bruising, and bleeding. Persistent adverse events of PLLA primarily are papule and nodule formation. Injecting PLLA into the anterior neck is an off-label procedure and may cause a higher incidence of nodule formation.

摘要

聚左旋乳酸（PLLA）是一种合成生物聚合物，悬浮在溶液中，可以注射用于软组织填充。最常见的不良反应通常是暂时性的，如肿胀、压痛、疼痛、瘀伤和出血。聚左旋乳酸的持续性不良反应主要是丘疹和结节形成。将 PLLA 注射到颈部前区是一种超适应证的操作，可能会导致更高的结节形成发生率。
