【摘要】：目的:根据最新的蝶窦分类方法对中国人的蝶窦进行分类研究,了解中国人的蝶窦发育状况。方法:收集100例成人蝶窦的CT检查资料,排除标准为CT显示有蝶窦病变、颅内肿瘤、颅面部解剖异常者。通过GE公司AW4.4图像后处理系统,利用MPR技术对原始图像进行x、y、z轴调整,得出标准对称的轴位、矢状位、冠状位重建图像。依最新的分类方法进行分类。结果:中国人的蝶窦气化程度似乎有"两极分化"趋势,即气化较差的如甲介型及鞍前型占10%,而气化良好者其气化程度远高于国外。蝶体型、外侧型、小翼型、前向型均未见,而斜坡型占26.66%,混合型占73.33%,中国人蝶窦的混合型比例更高。结论:蝶窦的不同气化程度对于各种经蝶手术操作会有重大影响,术前完善影像学检查,仔细对其进行分型,不仅有利于判断蝶窦的气化程度、分型,而且可以很好地明确蝶窦周围的重要血管、神经结构,甚至有助于判别其解剖标志,对于各种经蝶手术有极大帮助。
[Abstract]:Objective: to study the development of sphenoid sinus in Chinese according to the latest classification method of sphenoid sinus. Methods: Ct data of 100 adult patients with sphenoid sinus were collected. The exclusion criteria were CT findings of sphenoid sinus lesions, intracranial tumors and abnormal craniofacial anatomy. Through the image post-processing system of GE company AW4.4, the original image is adjusted by using MPR technology, and the standard symmetrical axial, sagittal and coronal reconstruction images are obtained. Classify according to the latest classification method. Results: the degree of sphenoid sinus gasification in Chinese people seems to be "polarized", that is, 10% of the cases with poor gasification, such as A type and presaddle type, have higher degree of gasification than those with good gasification. The sphenoid type, lateral type, small wing type and forward type were not found, while the clival type was 26.66 and the mixed type was 73.33. The proportion of mixed type in Chinese sphenoid sinus was higher than that in Chinese. Conclusion: different degree of vaporization of sphenoid sinus has great influence on various transsphenoidal operations. Improving imaging examination before operation and carefully classifying it are not only helpful to judge the degree of vaporization of sphenoid sinus, but also to the classification of sphenoid sinus. In addition, the important blood vessels and nerve structures around the sphenoid sinus can be well identified, and even the anatomical markers can be distinguished, which is of great help to all kinds of transsphenoidal operations.
