Studies on the muscular-deep fascial system which connects the upper eyelid, brow, and glabella, are lacking. This study aimed to explore the fine anatomy of the muscular-deep fascial system in the region between the eyebrow and the superior orbital margin. We included eight formalin-phenol-embalmed cadavers (16 sides of specimens), and categorized them into anatomical dissections and histological sections. Five cadavers (10 sides) were dissected for gross anatomical observation, whereas all soft tissues of the other three cadavers (6 sides) were dissected for tissue sectioning and histological analysis. Three tissue blocks and 16 strips in each block were trimmed, numbered, and sliced into these specimens. Hematoxylin-Eosin and Masson's Trichrome staining were performed. In the region between the eyebrow and the superior orbital margin, the frontalis was covered by the orbicularis oculi. Fibers of the frontalis muscle penetrated into the orbicularis oculi muscle bundles, and crosslinked around the eyebrow level. Both the frontalis and the orbicularis oculi were attached to the thickened multilayered deep fascia in this region, which could be regarded as the muscular-deep fascial system. The muscular-deep fascial system connects the frontalis deep fascia and deep forehead compartments down to the orbicularis-supporting ligament. The precise anatomy of the muscular-deep fascial system in the region between the eyebrow and the superior orbital margin may provide a valuable reference for soft-tissue fixation and suspension in facial surgery.
关于连接上眼睑、眉毛和额骨的肌肉-深部筋膜系统的研究较少。本研究旨在探索眉毛和眶上缘之间区域的肌肉-深部筋膜系统的精细解剖结构。我们纳入了 8 具福尔马林-苯酚固定的尸体（16 侧标本），并将其分为解剖学解剖和组织学切片。5 具尸体（10 侧）用于大体解剖观察，而另外 3 具尸体（6 侧）的所有软组织均用于组织切片和组织学分析。共修剪了 3 个组织块和每个块中的 16 个条带，并对其进行编号和切片。进行了苏木精-伊红和 Masson 三色染色。在眉毛和眶上缘之间的区域，额肌被眼轮匝肌覆盖。额肌的纤维穿过眼轮匝肌束，并在眉毛水平处交叉连接。额肌和眼轮匝肌均附着于该区域增厚的多层深部筋膜，可视为肌肉-深部筋膜系统。肌肉-深部筋膜系统将额肌深筋膜和深部额骨隔室连接到眼轮匝肌支持韧带。眉毛和眶上缘之间区域的肌肉-深部筋膜系统的精确解剖结构可能为面部手术中的软组织固定和悬吊提供有价值的参考。
