【摘要】：[目的]研究視神經(jīng)管及其內(nèi)部結(jié)構(gòu)的顯微解剖關(guān)系。探討外傷性視神經(jīng)管損傷的機制。[材料與方法]選取15例成人顱骨解剖標本。15例中國成人尸頭,沿垂直視神經(jīng)管方向制作斷層冰凍切片標本,在顯微鏡下觀察并測量視神經(jīng)管及其內(nèi)部結(jié)構(gòu)的解剖數(shù)據(jù)。運用SPSS軟件進行數(shù)據(jù)分析。 [結(jié)果]視神經(jīng)與視神經(jīng)管容積比在顱口處最小。視神經(jīng)管隆起與頸內(nèi)動脈隆起之間的距離平均3.01±0.12mm。視神經(jīng)管在管頂壁中后1/3交界處最薄。眼動脈在視神經(jīng)管顱口處位于視神經(jīng)正下方或內(nèi)下方,至管中部則位于視神經(jīng)的正下方,在眶口處則走行在視神經(jīng)的稍外下方。視神經(jīng)與視神經(jīng)鞘之間通過一些結(jié)締組織小梁相互連接。[結(jié)論]視神經(jīng)管在管頂壁中后1/3交界處最薄。視神經(jīng)管隆起與頸內(nèi)動脈隆起之間的距離平均3.01±0.12mm。外傷性視神經(jīng)損傷的機制主要是由于視神經(jīng)鞘與視神經(jīng)之間有結(jié)締組織小梁相連接,在突然的外力作用下視神經(jīng)受到牽拉所致。眼動脈在視神經(jīng)管顱口處位于視神經(jīng)正下方或內(nèi)下方,至管中部則位于視神經(jīng)的正下方,在眶口處則走行在視神經(jīng)的稍外下方。在做視神經(jīng)管減壓術(shù)時宜選擇管中部內(nèi)側(cè)壁與管頂壁中后1/3交界處至顱口同時切開減壓。
[Abstract]:[objective] to study the microanatomical relationship of optic canal and its internal structure. To investigate the mechanism of traumatic optic canal injury. [materials and methods] Fifteen adult cadaveric heads were selected and frozen sections were made along the vertical optic canal. The anatomical data of optic canal and its internal structure were observed and measured under microscope. SPSS software is used for data analysis. [results] the volume ratio of optic nerve to optic canal was the smallest at the cranial orifice. The distance between optic canal and internal carotid artery was 3.01 鹵0.12mm. The optic canal is thinnest at the posterior third of the parietal wall. The ophthalmic artery is located just below or below the optic nerve at the cranial orifice of the optic canal, directly below the optic nerve at the middle of the canal, and a little below the optic nerve at the orbital orifice. The optic nerve and optic nerve sheath connect with each other through some connective tissue trabeculae. [conclusion] the optic canal is thinnest at the posterior third of the parietal wall. The distance between optic canal and internal carotid artery was 3.01 鹵0.12mm. The mechanism of traumatic optic nerve injury is mainly caused by the connection of connective tissue trabecula between optic nerve sheath and optic nerve and the pull of optic nerve under the action of sudden external force. The ophthalmic artery is located just below or below the optic nerve at the cranial orifice of the optic canal, directly below the optic nerve at the middle of the canal, and a little below the optic nerve at the orbital orifice. Decompression of optic canal should be performed by cutting the medial wall and the posterior third of the parietal wall to the cranial orifice at the same time.
