There is a paucity of literature regarding aesthetic enhancement of the lips. This is due to the lack of reliable techniques employing autogenous tissue and the reluctance on the part of surgeons to use an alloplastic implant in this anatomic region, which is superficial, subject to trauma, and must conform to innumerable geometric shapes. The ideal lip augmentation procedure should provide for a predictable, permanent enlargement without visible scars or donor-site deformity, can be customized to the particular patient's anatomy, and can be reversed if so desired. A series of 21 alloplastic lip implants employing polytetrafluoroethylene with a mean follow-up of 14.33 months is presented. The overall complication rate was 9.52 percent. Permanent lip augmentation can be achieved with alloplastic sheet grafts of polytetrafluoroethylene in a safe and predictable fashion. Stiffness of the lips develops with progressive thickness of the grafts. Grafts exceeding 3 mm in thickness should be avoided.
关于唇部美学改善的文献较少。这是由于缺乏使用自体组织的可靠技术，以及外科医生不愿在这个解剖区域使用异体植入物，该区域表浅、易受创伤，且必须符合无数种几何形状。理想的唇部增大手术应能实现可预测的永久性增大，无明显疤痕或供区畸形，可根据特定患者的解剖结构进行定制，并且如果需要可进行逆转。本文介绍了一系列21例使用聚四氟乙烯的异体唇部植入物，平均随访14.33个月。总体并发症发生率为9.52%。聚四氟乙烯异体片移植可以安全、可预测的方式实现永久性唇部增大。随着移植片厚度的增加，唇部会出现僵硬。应避免使用厚度超过3毫米的移植片。
