背景资料：方法：对30具半侧面部尸体进行解剖学观察，将亚甲蓝注入面部特定区域后，将面部皮下脂肪分为不同的解剖分区。最初的工作集中在鼻唇沟脂肪。允许染料凝固至少24小时以实现一致的扩散。解剖在尸体实验室使用显微镜和放大镜magnification.Results：面部的皮下脂肪被分割成多个，独立的解剖隔间。鼻唇沟是一个具有明显解剖边界的离散单位。所谓的颧骨脂肪由三个独立的隔室组成：内侧，中间和外侧颞颊脂肪。前额类似地由三个解剖单位组成，包括中央、中间和外侧颞颊脂肪。眶脂肪被记录在由隔缘确定的三个隔室中。下颌脂肪是最低级的皮下脂肪隔间。被称为“保留韧带”的一些结构是简单地形成的这些compartment.Conclusions毗邻隔障的融合点：皮下脂肪的脸被分割成离散的解剖隔间。面部衰老的部分特征在于这些隔间如何随着年龄的变化而变化。分离的脂肪室的概念表明，面部不会作为汇合或复合物质而老化。相邻间室之间的剪切可能是软组织错位病因学的另一个因素。了解这种解剖结构将有助于更好地理解和更精确地进行术前分析和手术治疗的老化脸。
Background: Observation suggests that the subcutaneous fat of the face is partitioned as distinct anatomical compartments.Methods: Thirty hemifacial cadaver dissections were performed after methylene blue had been injected into specified regions. Initial work focused on the nasolabial fat. Dye was allowed to set for a minimum of 24 hours to achieve consistent diffusion. Dissection was performed in the cadaver laboratory using microscopic and loupe magnification.Results: The subcutaneous fat of the face is partitioned into multiple, independent anatomical compartments. The nasolabial fold is a discrete unit with distinct anatomical boundaries. What has been referred to as malar fat is composed of three separate compartments: medial, middle, and lateral temporal-cheek fat. The forehead is similarly composed of three anatomical units including central, middle, and lateral temporal-cheek fat. Orbital fat is noted in three compartments determined by septal borders. Jowl fat is the most inferior of the subcutaneous fat compartments. Some of the structures referred to as "retaining ligaments" are formed simply by fusion points of abutting septal barriers of these compartments.Conclusions: The subcutaneous fat of the face is partitioned into discrete anatomic compartments. Facial aging is, in part, characterized by how these compartments change with age. The concept of separate compartments of fat suggests that the face does not age as a confluent or composite mass. Shearing between adjacent compartments may be an additional factor in the etiology of soft-tissue malposition. Knowledge of this anatomy will lead to better understanding and greater precision in the preoperative analysis and surgical treatment of the aging face.
