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.
期刊介绍：
Ophthalmic Plastic and Reconstructive Surgery features original articles and reviews on topics such as ptosis, eyelid reconstruction, orbital diagnosis and surgery, lacrimal problems, and eyelid malposition. Update reports on diagnostic techniques, surgical equipment and instrumentation, and medical therapies are included, as well as detailed analyses of recent research findings and their clinical applications.
