Clinical Application of a Novel Augmented Reality Navigation System for Chronic Subdural Hematoma Surgery Using a...

Area of Science:

• Neurosurgery
• Medical Technology
• Augmented Reality

Background:

• Augmented reality (AR) enhances neurosurgical procedures by integrating 3D images with real-world views for better anatomical understanding.
• Current AR systems are often cumbersome and less appealing for surgical trainees.
• Wearable AR devices show potential but require further development.

Purpose of the Study:

• To assess a novel augmented reality navigation system (ARnavS) for burr-hole surgeries.
• To evaluate the convenience and accuracy of ARnavS in clinical application.
• To determine the system's utility in improving anatomical comprehension and safety during neurosurgery.

Main Methods:

• ARnavS utilizes a simultaneous localization and mapping algorithm and a quick response code.
• The system was applied in 10 cases of burr-hole surgery for chronic subdural hematoma.
• Evaluation focused on registration time, accuracy, surgical time, and patient outcomes.

Main Results:

• The ARnavS system was effective in 10 patients undergoing burr-hole surgery for chronic subdural hematoma.
• Average registration time was 2.6 minutes, with a mean burr-hole location discrepancy of 3.5 mm.
• No superficial temporal artery damage occurred, mean surgical time was 37.1 minutes, and no severe postoperative bleeding was reported.

Conclusions:

• ARnavS provides accurate intraoperative 3D imaging with rapid registration for burr-hole surgery.
• The system enhances surgeons' anatomical comprehension, aiding in the avoidance of critical structure injuries.
• ARnavS offers practical benefits for neurosurgical procedures, particularly for less-experienced surgeons and trainees.
