摘要
目的:观测蝶窦的形态变化及其与周围血管神经的关系,为有关蝶窦的手术提供解剖学和影像学资料。方法:对148例患者行鼻窦冠状位及横断位螺旋CT扫描及三维重建,从不同方位观察测量蝶窦的形态与周围血管神经的关系。结果:蝶骨体及其骨性突起的气化状况及程度变化很大,蝶骨小翼及前床突气化率与视神经管向蝶窦内的突出率相关(x2 = 60. 640,P< 0. 001)。斜坡气化率与颈内动脉向蝶窦内的突出率亦具显著相关性(χ2 =81.036,P<0.001)。翼突气化率与翼管向蝶窦内的突出率亦相关(χ2=9.317,P=0.002)。结论:蝶骨体及其骨性突起的气化状况影响其毗邻血管神经与蝶窦的距离及其向蝶窦内突出程度及位置。在对蝶窦形态大小各异的患者行有关蝶窦的手术前应从各方位充分了解蝶窦与其毗邻血管神经空间关系,减少损伤这些血管神经的危险性。
Objective: To investigate the relationship between human sphenoid sinus variations and the surrounding neurovascular structures, and to provide radiologic data fro transsphenoid sinus operations. Methods: Paranasal sinus was analyzed using computer tomographic scan in coronal and axial position and three-dimensional reconstruction in 148 cases of patients. Results: The position and protrusion of vessels and nerves related to sphenoid sinus were different in various extent and shape of the pneumatization. There was a significant relationship between the pneumatization of anterior clinoid process, little wing of sphenoid bone and the protrusion of the optic nerve into the sphenoid sinus (χ 2 =60.640, P<0.001). A significant relationship between the clivus of occipital bone and the protrusion of the internal carotid artery was found (χ 2 =81.036,P<0.001). There was also a significant relationship between the pneumatization of pterygoid process and the pterygoid (χ 2 =9.317,P=0.002). Conclusion: The variation of sphenoid sinus is obvious and the position and the protrusion of surrounding neurovascular structures is closely related to it. Coronal and the axial CT scan should be obtained prior to transsphenoid sinus surgery in order to reduce the risk of damaging adjacent neurovascular structures.
