【摘要】 目的　为手术治疗涉及眶上裂区肿瘤提供详尽的显微解剖及解剖参数。方法　应用２０ 例成人头颅湿标本， 在放大５ ×２５ 倍显微镜下， 对眶上裂区进行逐层显微解剖， 观察及测量。结果　眶上裂位于眶尖与海绵窦之间。被 Ｚｉｎｎ 腱环分为三部分： 外侧区、中央区和下侧区。滑车神经、额神经、泪腺神经及眼上静脉经外侧区穿行。动眼神经上、下支、外展神经、鼻睫神经及腱状神经节的交感根和感觉根均经中央区穿行。下侧区仅有眼下静脉穿行。本研究对穿行于上述各区域的神经及血管的行程及毗邻结构进行了显微解剖、观察和测量。结论　熟悉此区域的显微解剖， 术中可避免损伤重要的神经血管结构。更多还原

【Abstract】 Objective To supply the microsurgical anatomy for surgical treatment of tumors related to superior orbital fissure. Methods We examine twenty adult cadaveric heads and fifteen dry human skulls under5×to 25×magnification. The microsurgical anatomy of the superior orbital fissure was studied. Results The superior orbital fissure is a narrow cleft through which the orbit communicates with the middle cranial fossa. The cavernous sinus is situated behind the orbital apex and the superior orbital fissure. The fissure is divided into three sectors by the annular tendon: that are the lateral, central and inferior sector. The lateral sector is pass by the trochlear, frontal and lacrimal nerves and the superior ophthalmic vein. The central sector transmits the superior and inferior of divisions of the oculomotor nerver, the abducens and nasociliary nerves and the sensory and sympathetic roots of the ciliary ganglion. The inferior sector is pass by the inferior ophthalmic vein. The relationship and course of the nerves and vascular structures in each sector were reviewed. Conclusions The vital nerves and vascular structures can be protected in operation if we are familiar with the microsurgical anatomy of the superior orbital fissure.更多还原
