摘　　要：目的 提供中颅窝鞍旁区相关解剖学依据，为鞍旁区手术提供帮助。方法对38例成人尸颅进行手术巨微解剖，测量鞍旁区的硬膜关系、神经与血管走行及相邻结构的关系，并进行组织学观察。结果在中颅窝，动眼神经、滑车神经、展神经包裹着蛛网膜与硬脑膜深入中颅窝硬膜之间，Meckel腔、三叉神经节及其三个分支包裹着后颅窝蛛网膜与硬脑膜像三指手套深入中颅窝硬膜之间，颈内动脉及颅内、外静脉亦穿行于中颅窝硬膜间；上述结构与海绵窦在中颅窝鞍旁两层硬膜形成一个腔，即硬膜间腔。结论提出鞍区形态学特点，为中颅窝鞍旁区手术提供解剖学依据。Objective To study the surgical microanatomy of the parasellar region and its Related Structures. Methods The microsurgical dissections were performed on 38 cadaveric heads with the aid of an operating microscope to observe and measure the dura, nerves and vessels in the sphenopetroclival region, and to learn the relationships among the dura, nerves and vessels with bistochemical technique. Results In middle cranial fossa, cranial nerves Ⅲ, Ⅳ and Ⅵ, which were enwrapped by araehnoid and dura, entered between the dura of middle cranial fossa. The Meckel＇s cave, the trigeminal ganglion and its three branchs, just like a glove, were embedded between the dura of middle cranial fossa , and ICA and some venous structures traveled among them. Cavernous sinus and those structures were located in a cave made up of two floors of the middle cranial fossa dura, namely dura mater space. Conclusions We suggest a new constructive conception about this region which is the surgical anatomy based by the parasellar region approach.
