Abstract

Purpose: To study the microscopic anatomy of the orbital septum and evaluate its relationships with the adjoined structures.

Methods: Histological evaluation of 11 upper eyelids (5 right, 6 left) from 10 Japanese cadavers (age range: 36-94-year-old, average: 71.1) was performed. The specimens were fixed in 10% formalin and stained with Elastica Van Gieson. Specimens were microscopically analyzed using different magnifications (20×, 40×, and 100×).

Results: The orbital septum was the single fibrous layer in all the specimens, anteriorly separated from the retro-orbicularis fat pad capsule and posteriorly from the preaponeurotic fat pad capsule. At the junction of the orbital septum with the levator aponeurosis, the orbital septum proceeded towards the tarsal plate, and the preaponeurotic fat pad capsule reflected posteriorly.

Conclusions: The orbital septum is constituted of a single layer of fibrous tissue anteriorly separated from the retro-orbicularis fat pad capsule and posteriorly from the preaponeurotic fat pad capsule by the corresponding virtual spaces.

眼眶隔膜的显微解剖。

目的：研究眶隔的显微解剖，并评估其与毗邻结构的关系。方法：对 10 具日本尸体（年龄范围：36-94 岁，平均 71.1 岁）的 11 个上眼睑（5 右 6 左）进行组织学评估。标本用 10% 福尔马林固定，并用 Elastica Van Gieson 染色。用不同的放大倍率（20 倍、40 倍和 100 倍）对标本进行显微分析：结果：所有标本的眶隔都是单纤维层，前方与眼轮匝肌后脂肪垫囊分离，后方与眼球前脂肪垫囊分离。在眶隔与提上睑肌腱膜的交界处，眶隔向跗骨板延伸，而眼轮匝肌前脂肪垫囊则向后方反射：结论：眶隔由单层纤维组织构成，前方与眼轮匝肌后脂肪垫囊分隔，后方与眼球前脂肪垫囊通过相应的虚拟空间分隔。
