Summary
Electromagnetic navigation systems offer better surgeon comfort and faster setup than optical systems for endoscopic sinus surgery. Both systems enhance safety and efficiency in sinonasal and skull base procedures.
Area of Science:
- Otolaryngology
- Surgical Navigation
- Medical Device Technology
Context:
- Intraoperative navigation systems are crucial for enhancing safety and efficiency in endoscopic sinus surgery.
- Optical and electromagnetic navigation systems represent distinct technological approaches to image guidance in surgery.
Purpose:
- To compare the application and utilization of optical versus electromagnetic navigation systems in endoscopic sinus and skull base surgeries.
- To evaluate the precision, accuracy, setup time, operating room time, and surgeon's convenience of both navigation system types.
Summary:
- Electromagnetic systems demonstrated faster setup (5 min) and shorter operating room time (8 min) compared to optical systems (12 min setup, 22 min OR time).
- Both systems showed comparable accuracy in anatomical localization (optical: 1.62 ± 0.4mm; electromagnetic: 1.79 ± 0.39 mm).
- Electromagnetic systems provided superior surgeon working comfort and instrument manipulation fluency.
Impact:
- Intraoperative navigation systems significantly aid anatomical localization, improving safety and efficacy in endoscopic sinus surgery.
- The choice between optical and electromagnetic systems should consider cost-effectiveness and surgeon preference for optimal outcomes.
