BACKGROUND: The ability to incorporate different materials in the construction of 3-D printed models has resulted in the ability to mimic a variety of anatomical structures such as cartilage, mucosa and bone. The aim of this study was to evaluate the face and content validities of a model as a training tool for endoscopic sinus surgery.
METHODS: Twenty-six delegates and ten teaching faculty members were invited to complete a post-hoc questionnaire survey. The survey consisted of a 22-question 5-point Likert scale to assess the model's realism (face validity) and its effectiveness as a training tool (content validity).
RESULTS: Over 80% of the delegates agreed or strongly agreed that the appearance of anatomical structures within the model was realistic and mimicked actual sinus anatomy. In addition, a similar proportion agreed or strongly agreed that the application of instruments on the composite materials of the model realistically mimicked bone. All faculty agreed that the model was useful to develop hand-eye coordination and was a useful training tool for endoscopic sinus surgery. Overall, the sinus model received high scores regarding its use for training surgeons, especially to develop camera and instrument handling skills.
CONCLUSION: The results of this study suggest that otolaryngology doctors in their early or intermediate stage of training would benefit most from a clinical-based modular programme. The model requires further development in areas such as the realism of mucosa, incorporation of sinonasal pathology and having more complex anatomy to be useful for the training of more advanced surgeons.
