Comparison of Operating Microscope and Exoscope in a Highly Challenging Experimental Setting

Area of Science:

• Neurosurgery
• Surgical Technology
• Medical Imaging

Background:

• Digital 3D exoscope systems are increasingly used in neurosurgery as an alternative to traditional operative microscopes.
• This study aimed to compare the efficacy of a 3D exoscope with a standard operating microscope in a complex neurosurgical simulation.

Purpose of the Study:

• To evaluate and compare the performance of a digital 3D exoscope system against a standard operative microscope for neurosurgical visualization.
• To assess key parameters including task quality, depth perception, visualization, magnification, illumination, and ergonomics.

Main Methods:

• End-to-side bypass procedures were simulated at a depth of 9 cm.
• Comparative analysis of the digital 3D exoscope and operative microscope was performed based on task quality and ergonomic factors.

Main Results:

• No significant differences in procedural quality were observed between the 3D exoscope and the operative microscope.
• The 3D exoscope offered superior magnification and ergonomics, but required more time for depth and focus adjustments compared to the microscope.

Conclusions:

• Both the microscope and 3D exoscope demonstrated comparable procedural quality in a challenging experimental setting.
• The digital 3D exoscope presents potential as a future primary visualization system in microneurosurgery due to technological advancements.
