Three-dimensional high-definition neuroendoscopic surgery: a controlled comparative laboratory study with...

Area of Science:

• Neurosurgery
• Medical Imaging
• Surgical Technology

Background:

• Traditional two-dimensional (2D) endoscopy presents limitations in depth perception for complex surgical procedures.
• Advancements in imaging technology have led to the development of three-dimensional (3D) endoscopy for surgical applications.

Purpose of the Study:

• To compare the efficacy of 3D versus 2D endoscopy in neuroendoscopic surgeries.
• To evaluate the clinical utility and learning curve impact of 3D neuroendoscopy.

Main Methods:

• Forty-three participants with varying endoscopic experience (novice, beginner, expert) performed tasks using 3D and 2D neuroendoscopes.
• A 3D-printed skull model and an optical tracking system were used to assess performance metrics like execution time and path length.
• Clinical evaluation included 16 patients undergoing pituitary surgery with both 3D and 2D endoscopy.

Main Results:

• The 3D system significantly reduced execution time and path length in specific tasks for novice and beginner groups.
• 3D endoscopy demonstrated superior depth perception compared to 2D for less experienced surgeons.
• The 3D high-definition (HD) neuroendoscope proved valuable in visualizing critical anatomical structures during pituitary surgery.

Conclusions:

• 3D neuroendoscopy improves depth perception and task efficiency, especially for surgeons in training.
• The adoption of 3D endoscopy can potentially shorten the learning curve for neurosurgeons.
• 3D endoscopes are poised to become valuable tools in both general and neurosurgery.
