Abstract

Facial aesthetic procedures have become increasingly popular and complex, making knowledge of facial anatomy crucial for achieving desired outcomes without complications. Some of the most common procedures include blepharoplasty, bichectomy, face-lifts, facial implants, thread lifting, and fillers. Blepharoplasty and bichectomy are surgical procedures that respectively aim to restore youthful contours to the periorbita and create a slimmer lower face by removing Bichat fat from the maxillofacial region. Facial implants are used for aesthetic augmentation of the skeletal structure and restoration of facial contour by using biomaterials or autogenous bone grafts. Face-lift surgeries involve incisions and removal of excess skin, and thread lifts involve less invasive procedures performed by inserting threads beneath the skin, with the aim to lift the skin and thus reduce wrinkles and sagging. Fillers improve wrinkles and loss of facial volume, with biologic types made from animal, human, or bacterial sources (such as hyaluronic acid), while synthetic fillers include substances such as paraffin, silicone, calcium hydroxyapatite, polymethylmethacrylate microspheres, polyacrylamide hydrogel, hydroxyethyl-ethyl methacrylate, and poly-l-lactic acid. Synthetic fillers can be classified as rapidly resorbable (<12 months), slowly resorbable (<24 months), or permanent. Imaging modalities such as US, CT, and MRI can help identify and analyze each type of facial aesthetic procedure or filler, as well as their possible complications such as foreign-body granuloma, noninflammatory nodule, late intermittent persistent edema, filler migration, infection, or complications after removal of the buccal fat pad.

摘要

面部美容程序变得越来越流行和复杂,因此了解面部解剖结构对于实现预期效果而无并发症至关重要。一些最常见的程序包括重睑术、颊脂垫切除术、面部提升术、面部植入物、线雕和填充物。重睑术和颊脂垫切除术分别旨在通过去除颌面区域的颊脂垫,使眶周区域恢复年轻轮廓,使下面部更纤细。面部植入物用于通过使用生物材料或自体骨移植物来美容增强骨骼结构和恢复面部轮廓。面部提升术涉及切口和多余皮肤的去除,线雕术涉及在皮肤下插入线的侵入性较小的程序,目的是提升皮肤,从而减少皱纹和下垂。填充物通过使用生物类型(如透明质酸)的动物、人类或细菌来源或合成填充物(如石蜡、硅酮、钙羟磷灰石、聚甲基丙烯酸甲酯微球、聚丙烯酰胺水凝胶、羟乙基乙基甲基丙烯酸酯和聚 L-乳酸)改善皱纹和面部容积的损失。合成填充物可分为快速可吸收(<12 个月)、缓慢可吸收(<24 个月)或永久性。成像方式,如 US、CT 和 MRI,可帮助识别和分析每种类型的面部美容程序或填充物及其可能的并发症,如异物肉芽肿、非炎性结节、迟发性间歇性持续性水肿、填充物迁移、感染或颊脂垫去除后的并发症。RSNA,2023 本文的在线学习中心提供了相关测验问题。RSNA 年会的在线幻灯片演示可用于本文。
