在鼻和鼻窦的临床解剖研究中,常采用额状和矢状切面,较少用水平切面。作者用包括全部筛窦和蝶窦及其周围组织的整块尸体的横切面进行肉眼和显微镜检查。掌握这部分解剖知识可与常用的CT检查作比较,也可避免鼻和鼻窦手术并发症。在后组鼻窦顶部下的横切面的后部为蝶鞍,前外方为部分眼眶,二者之间为蝶窦和后组筛窦在此断面上可见到颈内动脉的二个切断面,因为它从下上行时形成了一个弯曲管,它贴在蝶窦的后外方,靠近鼻窦的顶壁并与眶后部总腱环相邻。它与蝶窦间的骨壁厚度为0.4mm。在视神经管下部的横切面上,气化良好的蝶窦骨壁极薄,仅70μm。此处有手术损伤,则有引起致命性出血的危险。筛窦的外侧壁由很薄的纸板与眶内容物隔
In the clinical anatomy of the nose and paranasal sinus, the frontal and sagittal sections are often used, with less horizontal sections. The authors performed a macroscopic and microscopic examination of the transverse section of the entire body including the entire ethmoid sinus and sphenoid sinus and its surrounding tissues. Mastery of this part of the anatomy of knowledge can be compared with the commonly used CT examination, but also to avoid the complications of nasal and sinus surgery. In the posterior group under the top of the transverse cross-section of the posterior sellae, anterolateral part of the orbit, between the two for the sphenoid sinus and posterior ethmoid sinus in this section can be seen in two sections of the internal carotid artery cut section, Because it forms a curved tube ascending from below, it sticks behind the sphenoid sinus, near the top wall of the sinuses and adjacent to the total tendon annulus behind the orbital. It is with the sphenoid sinus wall thickness of 0.4mm. In the transverse section of the lower part of the optic canal, the well-vaporized sphenoid sinus wall is extremely thin, only 70 μm. There are surgical injuries here, there is the risk of causing fatal bleeding. The outer wall of the ethmoid sinus is separated by a thin cardboard and orbital contents
