An Innovative 3 Dimensional Model of Middle Ear

Abstract

Background: Physical models are particularly useful in demonstrating complex topics in anatomy or those ones that are difficult to access when seen in the textbook or cadaver. One such topic is middle ear. Aim of the present study was to introduce a multicolored cardboard model of middle ear to provide ease in understanding of its anatomical structure. Methods: The participants were 2nd semester medical undergraduate class of students. They were exposed to a cuboidal multicolored model (made from cardboard box) with 6 walls that could be opened to see the details of structures related to them. Student feedback was taken through a structured Questionnaire based on Likert Scale (5 to 1). Results: More than 80% of students felt that this model was a good tool for visualizing complex anatomy of middle ear in small groups and it reduced the time needed for selfstudy. This model provided multifaceted feedback with active participation from students. A low fidelity middle ear model proved to be a practical low cost tool for use in both didactic and small group teaching. Conclusion: Low fidelity models continue to have a place in anatomy and can be integrated in the current curriculum.
