PARK, Jin Seo. 2D Browsing Software and 3D PDF of Canine Ear Based on Real Color Sectioned Images. Int. J. Morphol. [online]. 2020, vol.38, n.1, pp.147-152. ISSN 0717-9502.

Dog ear is very important because of disease vulnerability. Therefore, gross anatomy and sectional anatomy on CT and MRI of the dog ear should be mastered by veterinarian. The purpose of this research was to present the digital atlases which high quality sectioned images and 3D models of detailed structures of dog ear could be displayed freely. In the sectioned images of a female beagle, ear structures were reconstructed by surface modeling to make 3D models. The sectioned images and 3D models were put into the browsing software and PDF file, respectively. Using the browsing software and the PDF file, gross and radiological anatomy of dog ear could be learned easily and accurately. The auditory tube of a dog was placed anterior to the tympanic cavity unlike human. The tensor tympani muscle of a dog was connected to the dorsal wall of the tympanic cavity with the malleus. No remarkable difference in the auditory ossicles, semicircular ducts, facial nerve, and endolymphatic duct was observed between dogs and humans. The software and the PDF file will be provided to other researchers freely to help contribute to veterinary research and education.
