The purpose of this study was to describe the computed tomographic (CT) anatomy of normal donkey head cavities to be used as a basis for interpretation of CT images of donkey. Six adult donkeys' heads of undetermined sex were used in this study. The donkey heads were divided into three regions-nasal, orbital, and cranial-to show the morphology of the following cavities: nasal cavity, paranasal sinuses, orbital cavity, oral cavity, pharyngeal cavity, especially the guttural pouch, cranial cavity and temporomandibular joint. The donkey head had six pairs of sinuses: three paranasal (the frontal, maxillary and sphenopalatine sinuses) and three nasal (dorsal, middle and ventral conchal) sinuses. The maxillary sinus was subdivided into rostral and caudal compartments by a thin incomplete bony septum that was identified and labeled according to cheek teeth landmarks. The topographic description and relationship between the nasal, oral, orbital, cranial, temporomandibular joint, pharyngeal cavities and paranasal sinuses were demonstrated. The articular disc, articular surface and joint capsule of the temporomandibular joint were indicated easily in our CT and cross sectional images.
本研究的目的是描述正常驴头部腔隙的计算机断层扫描（CT）解剖结构，作为解释驴CT图像的基础。本研究使用了六只性别未确定的成年驴的头部。驴头被分为三个区域——鼻腔、眼眶和颅部——以显示以下腔隙的形态：鼻腔、鼻窦、眼眶腔、口腔、咽腔，尤其是咽鼓管囊、颅腔和颞下颌关节。驴头有六对鼻窦：三对鼻旁窦（额窦、上颌窦和蝶腭窦）和三对鼻腔窦（背侧、中间和腹侧鼻甲窦）。上颌窦被一个薄的不完全骨隔板分为前部和后部隔室，该隔板根据颊齿标志进行识别和标记。展示了鼻腔、口腔、眼眶、颅部、颞下颌关节、咽腔和鼻旁窦之间的地形描述及关系。在我们的CT和横断面图像中，颞下颌关节的关节盘、关节面和关节囊很容易显示出来。
