【 摘 要 】

References(42)The 2- and 3-dimensional (3D) anatomy and the morphometric properties of theparanasal sinuses of the foal have received little or no attention in the literature. Theaim of this study was to obtain details of the paranasal sinuses using multiplane CTimaging to create 3D models and to determine morphological and morphometric data for thesinuses using the 3D models. The heads of five female foals were used in this study. Theheads were scanned using computed tomography (CT) in the rostrocaudal direction. After theheads had been frozen, anatomical sections were obtained in the scan position. The 3Dmodels of sinuses and the skull were prepared using MIMICS®. These models wereused to assess the surface area and volume of the sinuses, the width, height andorientation of the apertures connecting these sinuses and finally the planar relation ofthe sinuses with the skull. The right and left sides of all anatomical structures, exceptthe sphenoid sinuses, had symmetric organization on CT images and anatomical sections. Thetotal sinus surface area and volume on both sides were 214.4 cm2 and 72.9ml, respectively. The largest and the smallest sinuses were the frontalsinus (41.5 ml) and the middle conchal sinus (0.2 ml),respectively. It was found that the planes bounding the sinuses passed through easilypalpable points on the head. In conclusion, 3D modeling in combination with conventionalsectional imaging of the paranasal sinuses of the foal may help anatomists, radiologists,clinicians and veterinary students.
