鼻窦炎是马的常见病。在人类医学中，它被描述为鼻窦炎的发展中鼻窦沟通障碍起着重要作用。为了获得马鼻腔与鼻窦之间特定沟通方式的空间感，对19匹2 ~ 26岁的马的头部进行了三维（3D）重新格式化的ct数据集渲染分析。通过手动和半自动分割生成三维模型。在分割之前，二维（2D） ct图像与相应的尸体头部冷冻切片进行验证。鼻窦三维分析显示，双侧存在7个窦室：上颌鼻窦吻侧、鼻窦腹侧、鼻窦尾侧、鼻窦背侧、额窦、蝶腭窦和鼻窦中。上颌隔将这七个腔室分成两个鼻窦系统：由上颌鼻窦吻侧和腹侧鼻窦组成的鼻侧鼻窦系统和由所有其他鼻窦组成的尾侧鼻窦系统。生成的三维模型显示了典型的鼻窦通信方式配置。鼻窦交通始于中鼻道的鼻上颌孔（Apertura nasomaxillaris），鼻上颌孔在共同的鼻窦通道（Canalis sinunasalis communis）中打开。这个共同的鼻窦通道分为鼻侧鼻窦通道（鼻侧鼻窦通道）和尾侧鼻窦通道（尾侧鼻窦通道）。鼻侧鼻窦通道通鼻侧鼻窦系统，尾侧鼻窦通道通尾侧鼻窦系统。鼻侧鼻窦通道以多种方式与鼻侧鼻窦相连。然而，尾侧通道显示较少的解剖变异，并且在所有病例中都与尾侧上颌窦相连。鼻窦通道的体积测量在头部左右两侧之间无统计学差异（P <0.05）。在生理条件下，这两个鼻窦系统通过马特有的鼻窦通道与鼻腔相连。为了解决鼻窦疾病，其目的是通过手术干预来维持甚至重建鼻窦交通的正常解剖结构。因此，所提出的三维分析可以提供一个有用的基础。
Sinusitis is a common disease in the horse. In human medicine it is described, that obstruction of the sinonasal communication plays a major role in the development of sinusitis. To get spatial sense of the equine specific communication ways between the nasal cavity and the paranasal sinuses, heads of 19 horses, aged 2 to 26 years, were analyzed using three-dimensional (3D) reformatted renderings of CT-datasets. Three-dimensional models were generated following manual and semi-automated segmentation. Before segmentation, the two-dimensional (2D) CT-images were verified against corresponding frozen sections of cadaveric heads. Three-dimensional analysis of the paranasal sinuses showed the bilateral existence of seven sinus compartments: rostral maxillary sinus, ventral conchal sinus, caudal maxillary sinus, dorsal conchal sinus, frontal sinus, sphenopalatine sinus and middle conchal sinus. The maxillary septum divides these seven compartments into two sinus systems: a rostral paranasal sinus system composed of the rostral maxillary sinus and the ventral conchal sinus and a caudal paranasal sinus system which comprises all other sinuses. The generated 3D models revealed a typically configuration of the sinonasal communication ways. The sinonasal communication started within the middle nasal meatus at the nasomaxillary aperture (Apertura nasomaxillaris), which opens in a common sinonasal channel (Canalis sinunasalis communis). This common sinonasal channel ramifies into a rostral sinonasal channel (Canalis sinunasalis rostralis) and a caudo-lateral sinonasal channel (Canalis sinunasalis caudalis). The rostral sinonasal channel ventilated the rostral paranasal sinus system, the caudo-lateral sinonasal channel opened into the caudal paranasal sinus system. The rostral sinonasal channel was connected to the rostral paranasal sinuses in various ways. Whereas, the caudal channel showed less anatomical variations and was in all cases connected to the caudal maxillary sinus. Volumetric measurements of the sinonasal channels showed no statistically significant differences (P <0.05) between the right and left side of the head. Under physiologic conditions both paranasal sinus systems are connected to the nasal cavity by equine specific sinonasal channels. To resolve sinus disease it is aimed to maintain or even reconstruct the normal anatomy of the sinonasal communication by surgical intervention. Therefore, the presented 3D analyses may provide a useful basis.
