Objectives/Hypothesis:
Develop a low-cost, medium-fidelity model for education in endoscopic sinus surgery techniques. Establish face and content validity of the model based on the feedback of otolaryngology faculty including fellowship-trained rhinologists.
Study Design:
Survey.
Methods:
A novel silicone injection molded sinus model was constructed. Three fellowship-trained rhinologists and four general otolaryngologists were recruited to perform seven tasks and provide feedback of the model's performance via a 22-question Likert survey.
Results:
Those surveyed strongly agreed the sinus model is useful for basic endoscopic skill acquisition such as camera skills (86%), hand-eye coordination (100%), nasal endoscopy skills (100%). Ratings of the model for training the specific tasks were consistently high. Neutral or lower were received for inferior turbinoplasty (14%), frontal balloon task (14%), understanding the ethmoid bulla (29%), and advanced sinus techniques (57%). All faculty strongly agreed they would be interested in using the model to train residents.
Conclusions:
Simulation models have proven efficacy in endoscopic skill and procedural training. The group developed a novel low-cost, medium-fidelity sinus training model utilizing three-dimensional modeling and printing. Testing of this model revealed high ratings for both face and construct validity for a range of endoscopic procedures. Strong interest in using this model for resident training was unanimous among all survey participants.
