An Innovative 3 Dimensional Model of Middle Ear
Keywords:Middle ear, 3 dimensional, teaching methodologies, gross anatomy education.
Background: Physical models are particularly useful in demonstrating complex topics in anatomy or those ones that are difï¬cult 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 self- study. This model provided multifaceted feedback with active participation from students. A low ï¬delity middle ear model proved to be a practical low cost tool for use in both didactic and small group teaching.
Conclusion: Low ï¬delity models continue to have a place in anatomy and can be integrated in the current curriculum.
