Summary
Functional endoscopic sinus surgery (FESS) with navigation systems improves surgical precision and thoroughness for chronic sinusitis. This advanced technique enhances outcomes while maintaining a high safety profile for patients.
Area of Science:
- Otolaryngology
- Medical Technology
- Surgical Navigation
Background:
- Functional endoscopic sinus surgery (FESS) is a primary treatment for refractory sinonasal diseases.
- Potential complications exist with traditional FESS.
- Navigation systems offer enhanced precision and safety during FESS.
Purpose of the Study:
- To evaluate the efficacy and safety of FESS assisted by a navigation system.
- To analyze key surgical metrics including setup time, operative time, accuracy, and blood loss.
Main Methods:
- A retrospective analysis of 79 patients undergoing FESS with navigation assistance.
- Data collected included preoperative setup time, navigation system accuracy, operative time, and blood loss.
- Comparison with historical data to assess improvements.
Main Results:
- Mean setup time was 10.6 minutes; mean operative time was 112.3 minutes.
- Navigation system accuracy averaged 1.08 mm.
- Significant improvements noted in reduced setup and operative times, and increased number of sinuses operated, indicating enhanced surgical skill. No major complications were reported.
Conclusions:
- FESS with navigation allows precise instrument guidance in 3D.
- Enables more thorough lesion removal.
- While safe for chronic sinusitis, it does not disclose vessel positions. Operative time decreased with experience, but blood loss increased with more aggressive procedures.
