目的探讨眶上裂区薄层冠状断层解剖，为临床眶上裂区疾病的影像诊断提供形态学依据。

Conclusion It is very necessary to master the anatomy of the superior orbital fissure and the surgical approach in the operation of this region .

如去除眶上裂的外缘，还可经外直肌与下直肌间进入眶上裂的中央区。结论熟悉眶上裂的解剖及其手术入路有助于该区的手术。

However , due to the impact of posterior ethmoid sinus , it is difficult to reach orbital apex and superior orbital fissure .

但由于后组筛窦的影响，眶尖和眶上裂则难以达到。

The most frequent invading sites were sphenoid sinus and orbit ( also including inferior and superior orbital fissure ), both of 18 cases .

侵犯部位最多为蝶窦和眼眶（包括眶上下裂），均为18例；

The anatomical relations between the middle section of the cavernous sinus , the optic canal and the superior orbital fissure were relatively invariable .

海绵窦中段的截面、视神经管和眶上裂的解剖关系相对固定。

Methods The serial sheet transverse sections of the superior orbital fissure region obtained using collodion microtomy in 5 adult cadaver heads were observed .

方法采用火棉胶切片技术对5例（10侧）眶上裂区标本连续薄层横断层切片进行解剖学观察。

Results : The frontal , nasociliary and lacrimal nerve , divisions of ophthalmic nerve , entered the orbit via the superior orbital fissure .

结果：眼神经的分支额神经、鼻睫神经和泪腺神经均经眶上裂入眶。

Cranio orbital communicating meningiomas : they grew between the orbital cavity and the cranial fossa through optic canal or superior orbital fissure .

眶颅沟脑膜瘤，肿瘤通过眶上裂、视神经管或骨质破坏缺损区呈哑铃形向眶内及颅内生长，等信号，增强显著。

Results The etiology of the pain can be classified into four major categories : vascular malformation , inflammation , tumor , cavernous sinus and superior orbital fissure lesions .

结果引起眼眶及眶周疼痛的眼眶病可大致分为：血管畸形，炎症，肿瘤，海绵窦-眶上裂病变。

The contents and their anatomic relationships of the cavernous sinus and superior orbital fissure were studied in 15 ( 30 sides ) adult cadaveric heads under operative microscope .

在显微镜下对15例（30侧）成人尸头标本暴露眶尖区及海绵窦，观察并测量其内容及毗邻关系。

This approach better reveals the contralateral cavernous sinus and reach the abducens nerve , oculomotor nerve and the superior orbital fissure outside contralateral internal carotid artery . 4 .

该入路对对侧的海绵窦显露得更好，可达到对侧颈内动脉外侧的外展神经、动眼神经和眶上裂。

The optic strut separates optic canal from superior orbital fissure , meanwhile , it separates the prominence of the optic nerve from the prominence of internal carotid artery in the lateral wall of the sphenoidal sinus .

视柱分隔视神经管和眶上裂，同时，在蝶窦外侧壁上，它分隔视神经隆突和颈内动脉隆突。

CS , a meningeal sinus formed between two layers of the dura mater , is located anteriorly to the superior orbital fissure and posteriorly to the apex of petrous portion of the temporal bone .

结果：海绵窦为颅中窝两层硬脑膜构成的硬脑膜窦，前端达眶上裂，后端达颞骨岩部尖。

Abducens nerve exhibited three different angulations during its course from the external side of brainstem to the superior orbital fissure , located at the dural entrance porus , the petrous apex and the lateral wall of the cavernous segment of ICA respectively .

展神经颅内段在行程中形成3个转角，分别位于脑膜入口处、岩尖及颈内动脉（ICA）的外侧面；

Methods A CT scanning was done for 30 adult cadaveric heads . The distance and angle of the lateral deviation from anterior nasal spine to the varial structures of the orbital apex , structures and the adjacent relationship of optic canal walls and the superior orbital fissure were measured .

方法随机选取30例成人尸头进行CT扫描，对前鼻棘至眶尖部各结构的距离、侧偏角、视神经管及眶上裂各径线长度、毗邻关系等进行断层影像解剖观测。

Results : The superior and inferior orbital fissure could be observed at the range of + 15 mm and 10 mm with the CM baseline . The optic canal was at the range of + 7 to + 12 mm with the CM baseline .

结果：眶上裂和眶下裂分别出现于CM基线上、下15mm和10mm范围内，视神经管影多见于CM基线上方7～12mmCT扫描层面。

Abducent nerve was ( 2.91 ± 1.02 ) mm inferior to the superior wall of superior orbital fissure .

展神经穿眶上裂处距其上壁（2.91±1.02）mm。

The superior ophthalmic vein passed through the narrow lateral sector of the superior orbital fissure by the outside of the common tendinous ring from the site between origins of the superior rectus muscle and lateral rectus muscle and drained into the cavernous sinus .

眼上静脉于上直肌和外直肌起点间经总腱环外面穿眶上裂外侧区注入海绵窦前下间隙，且与总腱环粘连紧密。
