In the last decade, interest in this technology increased considerably in the health sector, with subsequent investment in the field. Since then, chocolate, pens, toys, and even spacesuits have been produced using this equipment. Thus, testing to create the tools used in the production line commenced immediately. After a rapid evolution in these studies, the three-dimensional (3D) printer emerged its main function was to manufacture parts for the automotive industry and to produce prototypes. In the mid-1980s, the studies on stereolithography began. Interest in non-cadaveric representations of the temporal bone for dissection and learning has increased, since access to cadaver body parts is increasingly restricted, and, in some parts of the world, they are difficult to obtain because of legislative, religious, or cultural reasons. For this reason, theoretical knowledge, along with the practical study of corpses, must be acquired to understand its structure. The anatomy of the temporal bone is complex because of the several structures and functions present in this small bone space, which do not exist in any other region in the human body. After dissection of the bone biomodel, it was possible to find the anatomical structures proposed, and to reproduce the surgical approaches most used in surgical practice and training implants.
It is concluded that it is feasible to use biomodels in surgical training of specialist doctors. All structures proposed in the method were found with the proposed color.
With the difficulty of obtaining anatomical parts and the increasing number of ear, nose and throat (ENT) doctors, there was a need to create alternatives as real as possible for training otologic surgeons.ĭeveloping a technique to produce temporal bone models that allow them to maintain the external and internal anatomical features faithful to the natural bone.įor this study, we used a computed tomography (CT) scan of the temporal bones of a 30-year-old male patient, with no structural morphological changes or any other pathology detected in the examination, which was later sent to a 3D printer in order to produce a temporal bone biomodel.Īfter dissection, the lead author evaluated the plasticity of the part and its similarity in drilling a natural bone as grade “4” on a scale of 0 to 5, in which 5 is the closest to the natural bone and 0 the farthest from the natural bone. The anatomy of the temporal bone is complex due to the large number of structures and functions grouped in this small bone space, which do not exist in any other region in the human body.
