【皮下填充物文献】垂直支柱注射透明质酸填充剂用于深层皱纹
Perpendicular Strut Injection of HA Filler for
简介
【 文献重点摘要 】
Although various injection techniques of hyaluronic acid (HA) filler for facial rejuvenation have been developed, correction of deep wrinkles/grooves, such as the nasolabial fold (NLF), with intradermal or subdermal injections remains difficult. We tested the intradermal HA injection method to place multiple HA struts by (1) inserting a small needle perpendicularly to the wrinkle and (2) injecting HA as intradermal struts with the skin fully stretched by the practitioner’s fingers. The results of both NLFs in 10 patients suggest that this technique improves NLFs and maintain the effects more consistently than conventional techniques, although the effects of both methods were almost lost after 6 months. Selective and/or combined application of this technique may enhance the current approach to facial rejuvenation with dermal fillers.
尽管已经开发了各种透明质酸(HA)填充的面部年轻化注射技术，但通过皮内或皮下注射来矫正深皱纹/凹槽，如鼻唇皱褶(NLF)仍然很困难。我们测试了皮内注射HA的方法，通过(1)垂直于皱纹插入一根小针和(2)在医生手指充分伸展皮肤的情况下，将HA作为真皮内支柱注射。10例患者的两种NLF检查结果表明，虽然两种方法的效果在6个月后几乎消失，但该技术改善了NLFS并保持了比传统技术更一致的效果。这项技术的选择性和/或联合应用可能会增强目前使用真皮填充物进行面部年轻化的方法。
