Understanding human anatomy, and especially some very small organs such as the middle and inner ear, is challenging due to their complex three-dimensional structure. To build knowledge in understanding of anatomy, of the human inner and middle ear, from the 3D modeling and dissection experiment. Using DICOM images from a computerized axial tomography of the human ear converted to a 3D model (Mimics) and cadaveric dissections of the temporal bone, the bony and soft structures of the external, middle, and internal ear were designed, using organic modeling software. A standard operating protocol, 3D modeling of the middle and inner ear and 3D printing of the structures was created, differentiating each one by color. In this case, the dissection and modeling of the anatomical pieces was fundamental in the teaching and learning of this area of science, allowing expanded knowledge from the search for information, observation, analysis and reflection. The students showed fascination and deep learning in the practice carried out. The construction of explanatory models around qualitative experimentation allows an in-depth understanding of the different phenomena. The experimental activity overcomes the demonstration and facilitates thought process. The students achieve and in depth understanding of the middle and inner ear anatomy, acquired surgical skills, proposed and analyzed projects that allowed them to participate in academic event. They have also acquired additional skills, such as the comprehensive use of scientific knowledge.
