Summary:
- In this study, the 3-dimensional endoscopes were compared to the
2-dimensional endoscopes The study included clinical and cadaveric
phases we also used the need to use surgical navigation systems as a
new parameter to compare the accuracy of the 2D and 3D endoscopic
procedures.
- Navigation systems were needed less frequently with 3D endoscopes. The
difference between the 2 groups was statistically significant.,
- The duration of surgical procedures was significantly shorter when the
3-D endoscopes were used.
- Fewer intraoperative complications were reported during 3D endoscopic
procedures but the difference between the 2 groups was not
statistically significant.
- The cadaveric study revealed better depth perception and better
identification of anatomic landmarks with the 3D endoscopes. On the
other hand, there was no significant difference between the 2 groups
regarding the dissection time.
