Abstract
BackgroundThe middle ear is a complex anatomical space which is difficult to interpret from two-dimensional imagery. Appropriate surgical knowledge of the area is required to operate, yet current anatomical teaching methods are costly and hard to access for the trainee.MethodsA papercraft 3D design involving anatomical elements added separately to a model was designed, and then peer-validated by medical students and junior doctors. Preliminary quantitative assessment was performed using an anatomical labelling questionnaire, with six students given a lecture to act as a control. Qualitative feedback was also gathered.Results18 participants were recruited for the study. A total of 12 models were constructed by 6 medical students and 6 junior doctors. 6 medical students received a lecture only. Qualitative feedback was positive and suggested the model improved knowledge and was useful, yet timing and complexity were issues. Students scored, on average, 37% higher after completing the model, with junior doctors also improving anatomical knowledge, though these differences were not significant (p > 0.05).ConclusionsIn this initial investigation, the model was shown to be an engaging way to learn anatomy, with the tactile and active nature of the process cited as benefits. Construction of the model improved anatomical knowledge to a greater extent than a classical lecture in this study, though this difference was not significant. Further design iterations are required to improve practical utility in the teaching environment, as well as a larger study.
Highlights
The anatomy of the middle ear is intricate and conceptually complex
In addition to this, related anatomy is often hidden within bony canals, meaning that the surgeon must be able to operate without seeing some structures, yet knowing where they are; identifying and drilling only in areas they know to be safe
The observation of structures is often limited by the presence of other anatomy that can occlude the view [3]
Summary
Together with knowledge of the delicate anatomy passing through or near this space This mental model consisting of the morphology and interrelationships of anatomical structures must be conceptually adapted to accommodate different patient head angles, different approach methods, and the change in fields of view as the observer’s position is rotated around the patient’s head during surgery [1, 2]. More comprehensive three-dimensional methods of anatomical education exist, with dissection being the gold standard, yet there is extremely limited access especially to junior trainees and students [5]. Other models such as 3D printed temporal. Further design iterations are required to improve practical utility in the teaching environment, as well as a larger study
