The dorsal and ventral nasal conchal bullae and conchal sinuses are part of the complex equine paranasal sinus system and are commonly affected by secondary sinusitis. However, the radiographic anatomy of the conchal sinuses is poorly reported in the literature. The present study aimed to describe the radiographic anatomical characteristics of the nasal conchal bullae and conchal sinuses in mature horses. Six equine cadaveric heads without sinus or dental disorders were studied. A maxillary sinusotomy was performed to identify the dorsal and ventral nasal conchal bullae and conchal sinuses, allowing the application of radiopaque contrast medium in these structures. Afterward, the same projections were repeated. Laterolateral views allowed an adequate visualization of nasal conchal bullae and conchal sinuses; however, they overlapped the same contralateral structure. In the latero30°dorsal- lateroventral oblique view, the same structures were easily recognizable, but in an oblique view, the structures were projected dorsally in relation to the contralateral one. The dorsoventral view allowed partial visualization of the dorsal conchal bullae and dorsal sinuses, but it was not possible to identify the ventral conchal sinus and ventral conchal bullae. The offset dorsoventral view helped in the identification of the dorsal conchal bullae and dorsal conchal sinus, also achieving visualization of the medial region of the ventral conchal sinus and ventral conchal bullae. The use of contrast medium, added to the anatomical dissection, allowed a better radiographic identification of the sinuses and conchal bullae. The combination of different radiographic views is recommended for the evaluation of these structures.
鼻背侧和腹侧鼻甲泡及鼻甲窦是复杂的马属动物鼻窦系统的一部分，且常受继发性鼻窦炎影响。然而，文献中对鼻甲窦的放射学解剖描述较少。本研究旨在描述成年马鼻鼻甲泡和鼻甲窦的放射学解剖特征。研究了6个无鼻窦或牙齿疾病的马属动物尸体头部。进行上颌窦切开术以识别鼻背侧和腹侧鼻甲泡及鼻甲窦，以便在这些结构中应用不透射线的造影剂。之后，重复相同的投照。侧位片可充分显示鼻鼻甲泡和鼻甲窦；然而，它们与对侧相同结构重叠。在30°背侧 - 腹侧斜位片上，相同结构易于识别，但在斜位片中，这些结构相对于对侧向背侧投影。背腹位片可部分显示背侧鼻甲泡和背侧鼻窦，但无法识别腹侧鼻甲窦和腹侧鼻甲泡。偏移背腹位片有助于识别背侧鼻甲泡和背侧鼻甲窦，还能显示腹侧鼻甲窦和腹侧鼻甲泡的内侧区域。造影剂的使用加上解剖学分离，使鼻窦和鼻甲泡在放射学上能得到更好的识别。建议结合不同的放射学投照来评估这些结构。
