RESUMO

The studies that are related to the central nervous system (CNS) have premise, the knowledge of the structures that make part of it and the way that they are organized. "A smart diagnoses of a nervous system disease is whole dependent of a solid knowledge about anatomy, physiology and pathology of this system" (DE LAHUNTA, 1983), and between the auxiliary methods in the valuation of neurologic problems one of the most used is the image techniques, between them, the computed tomography, that is part of our study. The aims of this research were verify if there is or not difference in the sintopia and topography of the encephalon in the types of dogs heads (dolicocephalics, mesaticephalics and brachcephalics), using transversal and sagital sections and make too tomographic transversal sections to correlate the tomographic image with the anatomy with the objective in the identify the structures with more precision. To this study we used twenty seven dogs, 7 were dolicocefálicos (25,9%), 14 (51,9%) were mesaticephalics and 6 were brachcephalics (22,2%), of them, 16 were males (59,2%) and 11 were females (40,8%). The crosssections and the tomograms was make with about 1 centimeter and was photographic to label and analysis. We made only one sagital section in the median plane, in rostral - caudal course and a vertical red line was traced on the caudal margus of horizontal plate of the hard palate to record on what encephalic structure it will pass, to verify possible alterations on the encephalon position. Conclusion: there is difference in the sintopia and topography of the encephalon when his position is compared in the three types of heads (dolicocephalics, mesaticephalics and brachcephalics dogs). The difference is present more exactly in the relation between the position of the frontal lobe and his proximity with the eye bulb.
