Landmark based augmented reality endoscope system for sinus and skull-base surgeries.

Area of Science:

• Neurosurgery
• Otolaryngology
• Medical Imaging
• Surgical Navigation

Background:

• Endoscopic sinus and skull base surgeries require precise navigation.
• Current image-guided systems often overlay too much data, hindering usability.
• Augmenting endoscopic video with pre-operative information can improve surgical guidance.

Purpose of the Study:

• To develop and evaluate a simplified landmark-based Augmented Reality (AR) system for endoscopic sinus and skull base surgeries.
• To overcome limitations of current systems that rely on complex image slice augmentation.
• To provide effective navigation for surgeons using pre-selected landmarks.

Main Methods:

• Development of a simplified Augmented Reality (AR) system utilizing pre-operatively chosen landmarks.
• Integration of the AR system with the endoscopic video stream.
• Experimental validation using a plastic skull model and cadaver specimens.

Main Results:

• The developed landmark-based AR system was tested on physical models.
• Experimental results demonstrated the feasibility of the AR navigation approach.
• Subjective evaluation by an experienced surgeon confirmed the system's effectiveness.

Conclusions:

• A simplified landmark-based AR system offers a promising approach for surgical navigation in endoscopic sinus and skull base procedures.
• This method provides a less cluttered and potentially more intuitive navigation aid compared to existing systems.
• Further validation and clinical integration are warranted to fully assess its impact on surgical outcomes.
