Poly-L-lactic acid is a biodegradable synthetic polymer used in an injectable form for subcutaneous volume restoration. Volumetric correction following subcutaneous and deep dermal injection of poly-L-lactic acid is thought to occur through a foreign body tissue response leading to increased production of fibroblasts and subsequent neocollagenesis. Despite the growing popularity and use of this material, there has been a scarcity of published information describing proper injection technique, and many practitioners remain unfamiliar with its use. Appropriate injection technique is critical since incorrect placement of the material can lead to long-lasting unintended results. We present a protocol for successful injection of poly-L-lactic acid into the submalar and buccal regions.
聚左旋乳酸是一种可生物降解的合成聚合物，以注射剂形式用于皮下容积恢复。皮下和真皮深层注射聚左旋乳酸后的容积矫正被认为是通过异物组织反应导致成纤维细胞生成增加以及随后的新胶原形成来实现的。尽管这种材料越来越受欢迎且使用广泛，但关于正确注射技术的已发表信息却很少，许多从业者仍不熟悉其使用方法。合适的注射技术至关重要，因为材料放置不当会导致长期的意外后果。我们提出了一种将聚左旋乳酸成功注射到颧下和颊部区域的方案。
