Most options for rejuvenation of the lower face use soft-tissue fillers that augment the appropriate sites. Each of these options has associated risks and benefits. The U.S. Food and Drug Administration recently approved the use of expanded polytetrafluoroethylene (E-PTFE) as a soft-tissue filler in the face. From January 1991 through December 1993, the authors used E-PTFE soft-tissue patches for lower facial augmentation in 41 patients at 115 implant sites. Postsurgical follow-up has ranged from 2.5 to 4.5 years; during this time, complications have occurred in 4 patients. One implant had to be removed because of a seroma (1 patient), 4 implants required further secondary augmentation (2 patients), and 1 implant required revision because of malposition (1 patient). There have been no cases of implant infection, extrusion, long-term inflammation, or capsule formation. In this article, the authors review the technical aspects of E-PTFE use and discuss issues relating to the long-term efficacy of this new option for soft-tissue augmentation. The technique is also compared with other options for rejuvenation of the lower face.
大多数改善下面部外观的方法都使用软组织填充剂来填充相应部位。这些方法都有各自的风险和益处。美国食品药品监督管理局最近批准将膨化聚四氟乙烯(E-PTFE)用作面部软组织填充剂。从1991年1月至1993年12月,作者在115个植入部位为41例患者使用E-PTFE软组织补片进行下面部填充。术后随访时间为2.5至4.5年;在此期间,4例患者出现了并发症。1例患者因血清肿而取出1枚植入物,2例患者的4枚植入物需要进一步二次填充,1例患者因位置不当而对1枚植入物进行了修复。没有发生植入物感染、挤出、长期炎症或包膜形成的病例。在本文中,作者回顾了使用E-PTFE的技术要点,并讨论了这种软组织填充新方法的长期疗效相关问题。该技术还与其他改善下面部外观的方法进行了比较。
