摘要：

Simple Summary To date, there are very few studies of the bony nasal cavity of the domestic cat and even fewer of big felids. A detailed and exhaustive anatomical study of this cavity in the domestic cat is presented in this paper through dissections, trepanations and anatomical sections. This work has allowed to delve deeper into the anatomy of the bony nasal cavity. This study deepens the knowledge of this region through diagnostic imaging techniques, such as computed tomography, three-dimensional reconstruction in maximum-intensity projection and volume rendering, that allow for the spatial visualization of this cavity. These reconstructed images represent an improvement in the anatomical study of the cavity and will help veterinary clinicians in the diagnosis of nasal pathologies. Obtaining molds by three-dimensional printing allows for acquiring models very close to reality that capture these structures in detail. These techniques, which in human medicine have already led to many clinical and therapeutic improvements, are a very useful tool in veterinary medicine that will lead to advances and improvements in the diagnosis and treatment of nasal pathologies, improving the survival of many threatened species.Abstract This study aims to develop three-dimensional printing models of the bony nasal cavity and paranasal sinuses of big and domestic cats using reconstructed computed tomographic images. This work included an exhaustive study of the osseous nasal anatomy of the domestic cat carried out through dissections, bone trepanations and sectional anatomy. With the use of OsiriX viewer, the DICOM images were postprocessed to obtaining maximum-intensity projection and volume-rendering reconstructions, which allowed for the visualization of the nasal cavity structures and the paranasal sinuses, providing an improvement in the future anatomical studies and diagnosis of pathologies. DICOM images were also processed with AMIRA software to obtain three-dimensional images using semiautomatic segmentation application. These images were then exported using 3D Slicer software for three-dimensional printing. Molds were printed with the Stratasys 3D printer. In human medicine, three-dimensional printing is already of great importance in the clinical field; however, it has not yet been implemented in veterinary medicine and is a technique that will, in the future, in addition to facilitating the anatomical study and diagnosis of diseases, allow for the development of implants that will improve the treatment of pathologies and the survival of big felids.
