Summary
Image guidance systems improve anatomical localization in sinus surgery. Surgeons found the technology accurate and expressed high satisfaction, anticipating continued use in sinonasal procedures.
Area of Science:
- Otolaryngology
- Medical Technology
- Surgical Navigation
Background:
- Intraoperative guidance systems using infrared tracking assist anatomical localization in sinus surgery.
- The clinical impact of this technology on safety and efficacy is not well-documented.
Purpose of the Study:
- To study the application and utilization of a shared image guidance system in a specialty hospital setting.
- To assess the accuracy and physician satisfaction with image-guided sinus surgery.
Main Methods:
- A prospective case study and retrospective physician survey analysis.
- An optical-based image guidance system was used by 34 physicians for 754 sinonasal surgeries over 2.5 years.
- System accuracy was measured by repeating registration in 19 cases.
Main Results:
- The system's accuracy (mean 1.69 mm) aligned with surgeon perception (1-3 mm).
- Operating room time increased by 5-30 minutes, depending on experience.
- Over 90% of surgeons planned continued use of the system.
Conclusions:
- Optical-based image guidance systems can be integrated into multi-surgeon environments.
- The system provides accurate anatomical localization and high physician satisfaction in sinus surgery.
- This technology demonstrates successful application in clinical sinonasal surgery.
