Abstract

Abstract : Objective . To assess the face, content, and construct validity of the Voxel-Man TempoSurg Virtual Reality simulator. Participants and Methods . 74 ear, nose, and throat (ENT) surgeons participated. They were assigned to one of two groups according to their level of expertise: the expert group( n = 16 ) and the novice group( n = 58 ) . The participants performed four temporal bone dissection tasks on the simulator. Performances were assessed by a global score and then compared to assess the construct validity of the simulator. Finally, the expert group assessed the face and content validity by means of a five-point Likert-type scale. Results . experienced surgeons performed better( p < . 01 ) and faster( p < . 001 ) than the novices. However, the groups did not differ in terms of bone volume removed( p = . 11 ) or number of injuries( p = . 37 ) . 93.7% of experienced surgeons stated they would recommend this simulator for anatomical learning. Most (87.5%) also thought that it could be integrated into surgical training. Conclusion . The Voxel-Man TempoSurg Virtual Reality simulator constitutes an interesting complementary tool to traditional teaching methods for training in otologic surgery.
