Abstract：
BACKGROUND:Virtual reality simulators provide an effective learning environment and are widely used. This study evaluated the Endoscopic Sinus Surgery Simulator (ES3; Lockheed Martin) as a tool for anatomic education. METHODS:Two medical student groups (experimental, n = 8; control, n = 7) studied paranasal sinus anatomy using either the simulator or textbooks. Their knowledge was then tested on the identification of anatomic structures on a view of the nasal cavities. RESULTS:The mean scores were 9.4 +/- 0.5 and 5.1 +/- 3.0 out of 10 for the simulator and textbook groups, respectively (P = .009). Moreover, the simulator group completed the test in a significantly shorter time, 5.9 +/- 1.1 versus 8.3 +/- 2.0 minutes (P = .021). A survey asking the students to rate their respective study modality did not materialize significant differences. CONCLUSION:The ES3 can be an effective tool in teaching sinonasal anatomy. This study may help shape the future of anatomic education and the development of modern educational tools.
