面部筋膜位于皮下脂肪组织和结缔组织层之间，不像人体其他部位那样包裹肌肉表面。这种结构被称为浅肌腱膜系统(SMAS)，这是一个国际公认的解剖学术语。这种特殊的结构通常用于在面部拉皮等整形手术中拉动面部肌肉。包括SMAS在内的面部皮下组织结构的研究大多集中在整形外科领域，从形态学角度进行研究的报道较少。由于面筋膜不包裹肌肉表面层，不同于一般骨骼肌表面的深筋膜，因此对这种结构还没有一个明确的定义。本研究的目的是利用解剖标本而不是活体标本，通过扫描电子显微镜三维清晰地识别含有SMAS的皮下组织层的基本形态结构。此外，本研究还探索了面部七个老化区域的结构差异，从而进一步阐明了该结构的性质，并增加了临床意义和考虑因素。
Fascia of the facial area is contiguous between fat tissues of the subcutaneous and connective tissue layers and does not envelope the muscle surface like other parts of the human body. This structure is called the superficial musculoaponeurotic system (SMAS), which is accepted as an international anatomical terminology. This special structure is commonly used to pull facial muscles during plastic surgeries such as a face lift. Most reports regarding the facial subcutaneous tissue structure including SMAS are in the field of plastic surgery, and only a few studies from a morphological perspective has been reported. Since the facial fascia does not envelope the muscular surface layer which is different from the deep fascia found on the general skeletal muscle surface, a clear definition of this structure has not been established yet. The purpose of this study was to clearly identify the basic morphological structure of the subcutaneous tissue layer containing the SMAS three-dimensionally through a scanning electron microscope using dissected specimen rather than living subjects. Moreover, this study explores structural differences among seven aging facial areas; thereby further clarifying the properties of the structure and add clinical significance and considerations.
