Intraoperative navigation in oral and maxillofacial surgery

Area of Science:

• Oral and Maxillofacial Surgery
• Medical Technology
• Surgical Navigation

Background:

• Oral and maxillofacial surgeries are challenging due to complex anatomy.
• Traditional surgical planning relies on surgeon experience and 2D imaging.
• Limitations exist in precision and risk assessment with conventional methods.

Purpose of the Study:

• To evaluate a commercial 3D navigation system for oral and maxillofacial surgery.
• To assess the system's accuracy and impact on surgical planning and risk.
• To explore the potential of computer-assisted surgery in complex anatomical regions.

Main Methods:

• Utilized a 3D navigation system (Viewing Wand) with a 6-joint mechanical arm and computer graphics workstation.
• Registered patient head position to the instrument tip for real-time 3D visualization.
• Applied the system in 40 surgical interventions, documenting accuracy and case examples.

Main Results:

• Achieved an accuracy of 2 mm or better in 40 surgical interventions.
• Demonstrated facilitation of surgery in anatomically complex situations.
• Observed reduced risk of damaging neighboring structures during procedures.

Conclusions:

• 3D navigation systems significantly improve surgical planning and execution in oral and maxillofacial surgery.
• The technology enhances precision, reduces risks, and allows for more complex interventions.
• Computer-assisted simulation and navigation promise improved quality and safety in surgical procedures.
