Field of View Comparison Between 2D and 3D Endoscopy
Objective: Relative to microscopic transnasal surgery, endoscopic surgery provides improved visualization with an increased field of view. Advances such as high definition (HD) and 3-dimensional (3D) endoscopy have been introduced and clearly improve visualization. However, do both technologies maintain an increased field of view? We hypothesize that the field of view of 3D endoscopy is restricted relative to 2D HD endoscopy.
Methods: Standard measurements at 6-cm and 2-cm working distances were made to determine the comparative field of view, using Storz 0-degree 2D HD and Visionsense 3D endoscopes. Relative measurements were then made to determine field of view.
Results: 3D endoscopy demonstrates a 52% loss of field of view compared with 2D endoscopy.
Conclusion: When working with 3D endoscopy in its currently available commercial product, the operator should be aware that relative to 2D HD endoscopy there is a field of view restriction of 52%.
