背景:该研究的目的是使用CT图像描述荷斯坦奶牛颅腔底部的孔和运河的综合形态和形态特征。
方法:这项研究是对14只成年荷斯坦牛头尸体进行的。MSCT图像传输至DICOMViewer程序。该程序的MPR和3D重建工具用于分析有孔和运河。
结果:尽管它们的形状和大小各不相同,在所有动物的两侧都发现了有孔和运河。据观察,眶孔,颈静脉孔和卵圆孔有小管结构,颅内外开口之间的距离为15.0毫米,5.9毫米和6.2毫米,分别。舌下管,43%的人是单身,每个身体一半的50%和7%的三倍,是数量和形状变化最大的运河。轨道上的孔,面积为180.6mm²,直径为18.1×12.4mm的运河在颅底最宽,视神经管是最窄和最长的开口,面积为33.4平方毫米,直径为8.4×5.5,长度为17.5毫米。
结论:这项研究表明,我们对动物颅底形态计量学的了解极为有限。尽管这项研究是在有限数量的材料上进行的,它可能有利于提供的数据和兽医解剖学方面的区域解剖学知识,放射科医生和临床医生在方法论方面。
BACKGROUND: The aim of the
study was to describe the comprehensive morphological and morphometric features of the foramina and canals at the base of the cranial cavity in Holstein cow using CT images.
METHODS: The
study was performed on fourteen adult Holstein cow head cadavers. Images taken with MSCT were transferred to the DICOM Viewer program. The MPR and 3D reconstructive tools of the program were used to analyse the foramina and canals.
RESULTS: Although they varied in shape and size, foramina and canals were found bilaterally in all animals. It was observed that the orbitorotund foramen, jugular foramen and oval foramen had a canalicular structure, with the distance between the extra-intra cranial openings measured as 15.0 mm, 5.9 mm and 6.2 mm, respectively. The hypoglossal canal, which was found to be single in 43%, double in 50% and triple in 7% in each body half, was the canal with the most variation in number and shape. The orbitorotund foramen, a canal with an area of 180.6 mm² and a diameter of 18.1 × 12.4 mm is the widest at the skull base, while the optic canal is the narrowest and longest opening with an area of 33.4 mm², a diameter of 8.4 × 5.5 and a length of 17.5 mm.
CONCLUSIONS: This
study shows that our knowledge of skull base morphometry in animals is extremely limited. Although the
study was conducted on a limited number of materials, it may benefit both regional anatomy knowledge in terms of the data presented and veterinary anatomists, radiologists and clinicians in terms of methodology.
