Three-dimensional endoscopy as a teaching tool
All participants commented that 3D endoscopy could be effective to facilitate teaching. The 3D endoscopy system provides a more complete projection of complex anatomical structures including the vocal cords and surrounding topography of the larynx. Three-dimensional imaging of such structures allowed trainees to better understand anatomical relationships ultimately targeted to improve their surgical precision. Moreover, 3D endoscopy allowed supervising surgeons to more precisely follow surgical movements of trainees, thus improving the senior surgeons’ confidence that maneuvers were conducted in a safe manner.
