Introduction: The middle and the inner ear have a complex anatomical constitution. As a traditional teaching method, the dissection provides an optimal knowledge of the three-dimensional configuration of its structures due to its practical and realistic qualities. It proposes a protocol of isolated dissection of the middle and the inner ear offering a broad vision of its structures and incorporates didactic schemes. Materials and Method: We delimited two quadrants in the upper face of the temporal bone of three conserved human corpses by employing anatomical referents to extract a parallelepiped structure that corresponds to the petrous portion of the
temporal bone. On this portion, the dissection was performed. Results: we created a dissection protocol following this sequence: The petrous portion of the temporal bone partial removal, middle ear visualization, tympanic membrane exposure and inner ear visualization. Conclusion: This pedagogical instrument is applicable to the process of education and constitutes a resource whose didactic character results potentially useful for the students facilitating the active learning of the theoretical and practical issues of the ear anatomy.
