Applied anatomy of adult optic canal and its associated structures
摘要
Abstract
Objective To study the optic canal and its associated structures to provide anatomical basis for the transcranial decompression of optic nerve. Methods 10 well-reserved adult cadaveric heads fixed by formalin as well as 5 adult dry skull specimens were randomly selected to observe and measure their optic canals and the related structures under a microscope. Results ① The transverse areas in cranial orifice, middle part, orbital orifice of the optic cana were (19. 22 ± 4. 58), (18. 26 ± 4. 33), (21. 08 ± 3. 96) mm2, respectively;the distance from en-docranial opening of optic canal to glabella was (63. 88 ± 4. 63) mm, and the range from endocranial opening to pterion was (51. 97 ± 2. 98) mm. ②The total length of the anterior clinoid process was (9. 52 ± 0. 38) mm, width of its root was ( 11. 45 ± 0. 67 ) mm. The percentage of anterior clinoid gasification was 20%. Anterior clinoid process was close to cranial nerve and internal carotid artery. ③Falciform ligament, annular tendon and the region dura were relatively tough and firm, and no significant space was between them and the optic nerve. ④ Three trochlear nerves (15%) in this group were pulled by posterior ethmoidal arteries, causing them to be close to supe-rior rectus tendons. ⑤The ophthalmic artery went beneath the optic nerve when it was in the optic canal. Conclu-sion ① Optic canal should be full cut. ②It can reduce the chance of damage to cranial nerve and internal carot-id artery by grinding anterior clinoid process correctly. ③The method to incise falciform ligament and the dura ver-tically on the optic nerve, and to slit annular tendon close to the inside when near the orbital orifice, can depressur-ize optic nerve effectively, and it also can reduce the chance of damage to the trochlear nerve and avoid damage to the ophthalmic artery.关键词
