Objective: In this study, microanatomy of SOF was evaluated in the scope of surgical exposure feasibilities of the nerves and the vascular structures.

Materials and methods: Five skulls and 5 cadaveric heads were used in this study. The length and the diameter of the superior orbital fissure were measured in the skulls. Arteria carotis communis, arteria vertebralis, and vena jugularis interna were catheterized in the formalin fixed cadavers. The vessels were injected with colored silicone. The stages of the dissection through a photographic camera.

Conclusions: Bone resection on roof and lateral wall of the orbit extending 1.5 cm supero-medial and 1.5 cm inferolateral to SOF was found to be sufficient to expose SOF. It was noticed that frontal nerve posed a significant landmark right after the periorbit has been opened. Superior ophthalmic vein passing through was noted to be an alternatiye route to reach cavernous sinus in the treatment of carotico-cavernous fistula.
