蝶窦位于鼻窦最后部,它的大小也不尽相同,邻界与颈内动脉、视神经管等颅内重要结构相连接。在进行蝶窦、下垂体手术时,熟悉其外科解剖是十分重要的。本报告应用高分辨CT断层图象对耳部疾病(慢性中耳炎、耳聋、耳鸣)进行诊断同时并被用于蝶窦的形态学研究。在412名受试者中,男性224名,女性188名,平均年龄为47.5岁。其中没有任何人有窦腔损害的迹象。外科手术中有重要价值的各型中隔范围是:横切面上占10.9%,中间位占9.4%,额状面上占14.1%,矢状面上占41.5%,位于窦中的占95.1%。在所见的95.1%的窦中
Sphenoid sinus is located in the last part of the sinuses, its size is not the same, the adjacent sector and the internal carotid artery, optic nerve tube and other intracranial important structures connected. In the sphenoid sinus, pituitary surgery, familiar with its surgical anatomy is very important. This report uses high-resolution CT tomographic images for the diagnosis of otological diseases (chronic otitis media, deafness, tinnitus) and is used in morphological studies of the sphenoid sinus. Of the 412 subjects, 224 were males and 188 were females, with an average age of 47.5 years. No one has any signs of sinus damage. There are various types of septal ranges of great value in surgery: 10.9% in the transverse section, 9.4% in the median, 14.1% in the frontal plane, 41.5% in the sagittal plane, and 95.1% in the sinus . In 95.1% of the sinus seen
