【摘要】：目的研究经鼻入路视角下蝶窦外侧壁和海绵窦内侧壁的显微解剖特征,为相关手术提供形态学依据。方法 10例防腐尸颅按经鼻路径在显微镜下进行解剖,观测视神经、颈内动脉和蝶窦外侧壁的关系,测量前鼻棘与视神经管眶口、颈内动脉隆凸最凸点之间的距离,以及与鼻底平面的角度。结果颈内动脉和视神经在蝶窦外侧壁上形成隆凸,两者之间呈""字形,前鼻棘与颈内动脉隆起最凸点之间的距离为(62.18±5.12)mm,与鼻底平面的夹角为(36.8±3.4)°,与视神经管眶口的距离为(69.24±3.95)mm,与鼻底平面的夹角(41.4±3.0)°。颈内动脉海绵窦段可分为鞍旁部和斜坡旁部,鞍旁部与垂体外侧壁关系最为密切,鞍旁部至中线的距离为(9.06±1.34)mm。海绵窦内侧壁由鞍旁部和蝶窦旁部组成。结论熟悉蝶窦外侧壁和海绵窦内侧壁的解剖学特点,对于术中定位,安全处理海绵窦病变有重要意义。
[Abstract]:Objective to study the microanatomical features of lateral wall of sphenoid sinus and medial wall of cavernous sinus from the perspective of transnasal approach, and to provide morphological basis for related operations. Methods Ten cadaveric cadavers were dissected under a microscope by transnasal pathway to observe the relationship between optic nerve, internal carotid artery and lateral wall of sphenoid sinus, and to measure the distance between anterior nasal spine and orbital orifice of optic canal and the most protruding point of internal carotid artery protuberance. And the angle to the nasal floor plane. Results the medial carotid artery and optic nerve formed protuberance on the lateral wall of sphenoid sinus. The distance between anterior nasal spine and the most protruding point of internal carotid artery was (62.18 卤5.12) mm, and (36.8 卤3.4) 掳, and the distance between anterior nasal spine and the orbital orifice of optic canal was (69.24 卤3.95) mm, and (41.4 卤3.0) 掳. The cavernous sinus of the internal carotid artery can be divided into parasellar part and paraphoric part. The relationship between the parasellar part and the lateral pituitary wall is the most close. The distance between the parasellar part and the midline is (9.06 卤1.34) mm.. The lateral wall of cavernous sinus is composed of parasellar part and sphenoid sinus part. Conclusion it is important to know the anatomical features of lateral wall of sphenoid sinus and medial wall of cavernous sinus and to treat cavernous sinus lesion safely during operation.
