Abstract

Perineum is a clinically important but difficult site to dissect. Because the cadaver is limited in maintaining the shape of the pelvis and learning the perineal region layer structure, so a three-dimensional understanding using anatomical supplementary materials is essential. The illustration of anatomy atlas could be misunderstood that the urogenital triangle and anal triangle are in parallel position. Anatomical 3D training materials are cumbersome and difficult to see because of the user’s environment in which the necessary parts must be configured. The purpose of this study is to provide a three-dimensional understanding of the perineal region layer structure. Therefore, I will study educational pictures that complement the limitations of existing supplementary materials for health workers who are learning anatomy. The illustrations I studied are the urogenital triangle, anal triangle, pelvic bone, pelvic floor, deep perineal space, superficial perineal space, perineum, perineal layer section, perineal layer sequence. These have the following advantages. It is possible to see the perineal region layer structure at a time while maintaining the shape of the pelvis. Conceptually identify structures that are difficult to observe in the cadaver. Identify deep perineal space and superficial perineal space and look at the structures located in each space. Complements the sagittal and coronal sections illustrations in the anatomy atlas. In educational posters, you can find all the perineal region layer structure. Educational PDF lets you turn layers on or off. This must be done by the learner and enables intuitive learning. In the next study, it is suggested to create educational illustrations by extending to the pelvic organs, blood vessels, and nerves.The results of this study are expected to be used as a useful educational illustration for a three-dimensional understanding of the perineal region layer structure.
