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.
