副鼻窦系统在形态上代表了马身体最复杂的部分之一。正确的诊断和治疗需要对空间关系有清楚的了解。本研究的目的是使用计算机断层扫描（CT）切片的三维（3D）重建效果图描述马副鼻窦的解剖结构和体积。通过使用以下双侧副鼻窦室的单独半自动分割，分析了18匹2-25岁尸体马的头部：喙上颌窦（上颌窦嘴侧），腹侧耳甲窦（耳甲腹侧窦），上颌窦尾侧（上颌窦尾侧），耳甲背窦（Sinus conchae dorsalis）、额窦（Sinus frontalis）、蝶腭窦（Sinus sphenopalatinus）和中甲窦（Sinus conchae mediae）。重建的结构分别显示，分组，或完全透明或固体元素可视化个别鼻窦形态。副鼻窦似乎分为两个系统的上颌隔（中隔窦上颌）。第一或吻侧系统包括上颌窦吻侧和耳甲腹侧。第二或尾侧系统包括上颌窦尾侧、耳甲背侧、额窦、蝶腭窦和中耳甲窦。这两个系统重叠，并由于上颌隔的倾斜方向互锁。鼻窦总体积范围为911.50 - 1502.00 ml（平均值± SD，1151.00 ± 186.30 ml）。通过使用CT数据集的半自动分割，马鼻旁窦的3D渲染提高了对这一解剖学上具有挑战性的区域的理解。
The system of the paranasal sinuses morphologically represents one of the most complex parts of the equine body. A clear understanding of spatial relationships is needed for correct diagnosis and treatment. The purpose of this study was to describe the anatomy and volume of equine paranasal sinuses using three-dimensional (3D) reformatted renderings of computed tomography (CT) slices. Heads of 18 cadaver horses, aged 2-25 years, were analyzed by the use of separate semi-automated segmentation of the following bilateral paranasal sinus compartments: rostral maxillary sinus (Sinus maxillaris rostralis), ventral conchal sinus (Sinus conchae ventralis), caudal maxillary sinus (Sinus maxillaris caudalis), dorsal conchal sinus (Sinus conchae dorsalis), frontal sinus (Sinus frontalis), sphenopalatine sinus (Sinus sphenopalatinus), and middle conchal sinus (Sinus conchae mediae). Reconstructed structures were displayed separately, grouped, or altogether as transparent or solid elements to visualize individual paranasal sinus morphology. The paranasal sinuses appeared to be divided into two systems by the maxillary septum (Septum sinuum maxillarium). The first or rostral system included the rostral maxillary and ventral conchal sinus. The second or caudal system included the caudal maxillary, dorsal conchal, frontal, sphenopalatine, and middle conchal sinuses. These two systems overlapped and were interlocked due to the oblique orientation of the maxillary septum. Total volumes of the paranasal sinuses ranged from 911.50 to 1502.00 ml (mean ± SD, 1151.00 ± 186.30 ml). 3D renderings of equine paranasal sinuses by use of semi-automated segmentation of CT-datasets improved understanding of this anatomically challenging region.
