A wide variety of implants and grafts have been used for cosmetic facial surgery, including forehead, nose, cheek, lip, and chin augmentation. Some of the implant materials include silicone, expanded polytetrafluoroethylene (Gore-Tex), hydroxylapatite, and porous polyethylene (Medpor). Grafts include bone and cartilage, which can be prepared as "Turkish Delight" for rhinoplasty. Imaged facial implants and grafts can be encountered incidentally or purposely to evaluate complications. Many of these materials have distinct radiologic imaging features and should not be misinterpreted as pathology. Conversely, implant complications should be appropriately recognized by using a focused imaging approach. The purpose of this article was to review the different types of cosmetic facial implants and grafts with an emphasis on their expected and complicated radiologic imaging appearances.
各种植入物和移植物已被用于美容面部手术，包括额部、鼻部、颊部、唇部和颏部的填充。一些植入物材料包括硅树脂、膨化聚四氟乙烯（ Gore-Tex ）、羟基磷灰石和多孔聚乙烯（ Medpor ）。移植物包括骨和软骨，可制备成“土耳其软糖”用于鼻整形术。成像面部植入物和移植物可偶然或有意地遇到，以评估并发症。许多这些材料具有明显的影像学特征，不应被错误地解释为病理学。相反，应通过使用有针对性的成像方法来适当识别植入物并发症。本文的目的是复习不同类型的美容面部植入物和移植物，重点介绍其预期和复杂的影像学表现。
