Summary: | To investigate the key microanatomic and radiological structures of optic canal comprehensively so as to provide anatomic parameters and procedural flows for the decompression of optic canal.
Gross observations and microscopic measurements were applied on 10 (20 sides) formalin-treated cadaveric specimens and 15 (30 sides) adult skulls. Using multislice helical CT (computed tomography)-aided three-dimensional reconstruction in combination with direct anatomic measurement, the investigators dissected, photographed, measured and analyzed the shape of optic canal and analyze its anatomic relationship with the adjoining structures.
Optic canal was formed by the superior, inferior, medial and external walls and distal proximal opening. The lateral wall of optic canal was formed by anterior clinoid process with a length of (9.87 ± 1.34) mm, a width of (11.66 ± 2.35) mm, a base thickness of (5.35 ± 1.07) mm and a middle thickness of (4.50 ± 1.06) mm. Optic strut separating the optic canal from the superior orbital f |
