The domestic Pig (Sus scrofa domestica)has been used as a model to study implants methods in clinical cases of the human middle ear. Different studies have highlighted the usefulness in this area, as well as its high morphological comparability with regard to humans. However, the anatomical descriptions about its ear bones are scarce, as comparisons in relation to the human. Therefore, in order to make a detailed description of the anatomy of these bones compared to human, it was necessary to dissect six pig heads of which its ossicles were removed to observe its morphology. Preliminary results showed that the pig'sossicles share the same anatomical formations that can be identified in the human ones, but there are some descriptive and morphometric differences in its morphology. The results concluded that there is high comparability between both morphological ossicular chains due to their differences and similarities, which makes it a great teaching model for the study and teaching of auditory morphology at different educational levels.
