Abstract
Introduction 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. 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.
Objective Developing a technique to produce temporal bone models that allow them to maintain
the external and internal anatomical features faithful to the natural bone.
Methods For 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.
Results After 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. All structures proposed
in the method were found with the proposed color.
Conclusion It is concluded that it is feasible to use biomodels in surgical training of specialist
doctors. 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.
