The process of aging is the result of subcutaneous loss of volume, in addition to vertical tissue descent. Surgeons are therefore emphasizing soft tissue augmentation to achieve a natural, rejuvenated appearance in patients. Autologous fat grafting is now a commonly performed aesthetic procedure. Autologous fat grafting is a challenging procedure, due to the fragile characteristic of adipose tissue. Viability of transplanted fat is a main consideration when fat grafting is performed. Poor fat viability produces an inadequate result and thus can be considered as a complication of this procedure. Many studies have demonstrated that fat longevity is dependent upon handling and preparation of fat. This article outlines the history of autologous fat grafting. The technique of fat grafting is described, along with review of the evidence of fat viability according to the technique used. The specific technique for autologous fat grafting in the lower third of the face is described including augmentation of the labiomandibular fold, lips, chin, and the jaw.
衰老过程是皮下容积减少以及组织垂直下移的结果。因此，外科医生强调通过软组织填充来让患者获得自然、年轻化的外观。自体脂肪移植如今是一种常见的美容手术。由于脂肪组织的脆弱特性，自体脂肪移植是一项具有挑战性的手术。进行脂肪移植时，移植脂肪的存活率是主要考虑因素。脂肪存活率低会导致效果不佳，因此可被视为该手术的一种并发症。许多研究表明，脂肪的留存率取决于脂肪的处理和制备方式。本文概述了自体脂肪移植技术的发展历程。描述了脂肪移植技术，并根据所使用的技术对脂肪存活率的证据进行了综述。还介绍了面部下三分之一区域自体脂肪移植的具体技术，包括唇下颌皱襞、嘴唇、下巴和下颌的填充。
