The anatomical relationships of the orbital septum and levator aponeurosis has been studied in 40 eyelids subjected to blepharoplasty and corrective ptosis surgery by dissection in 10 cadavers and in histological sections. The orbital septum originates from the arcus marginalis of the frontal bone and consists of two layers. The whitish outer (superficial) layer, containing vertically running vessels, descends just inside the orbicularis oculi muscle to interdigitate with the levator aponeurosis with loose connective tissue, then disperses inferiorly. The inner (deep) layer follows the superficial one initially, then reflects at the levator aponeurosis and continues posteriorly with the levator sheath. We reconfirmed Whitnall's original description that the levator sheath thickens to form the superior transverse ligament runs continuously inferiorly anterior to the levator aponeurosis and forms the inner layer of the orbital septum. This detailed anatomical analysis should assist in performing upper eyelid surgery such as the Oriental double fold operation or levator resection.
通过对10具尸体进行解剖以及组织学切片，研究了40例接受眼睑成形术和上睑下垂矫正手术的眼睑中眶隔与提上睑肌腱膜的解剖关系。眶隔起源于额骨的眶缘，由两层组成。白色的外层（浅层）含有垂直走行的血管，在眼轮匝肌内侧下降，与提上睑肌腱膜通过疏松结缔组织相互交错，然后向下散开。内层（深层）最初跟随浅层，然后在提上睑肌腱膜处折返，继续向后与提上睑肌鞘相连。我们再次证实了惠特纳尔最初的描述，即提上睑肌鞘增厚形成上横韧带，在提上睑肌腱膜前方连续向下延伸，形成眶隔的内层。这种详细的解剖分析有助于进行上睑手术，如东方双眼皮手术或提上睑肌切除术。
