This study shows that using a developed optical computer-aided surgery (CAS) system for revision endoscopic sinus surgery (RESS) aids surgeons in identifying difficult anatomical landmarks. The CAS system improved safety and reduced surgeon stress without complications.

Area of Science:

  • Otolaryngology
  • Medical Technology
  • Surgical Navigation

Background:

  • Revision endoscopic sinus surgery (RESS) presents challenges due to altered anatomy and difficulty visualizing landmarks.
  • Intraoperative safety and accurate anatomic guidance are crucial for successful RESS outcomes.

Purpose of the Study:

  • To evaluate the utility of a novel optical computer-aided surgery (CAS) system for enhancing safety and providing anatomic assistance during RESS.
  • To assess the clinical performance and accuracy of the developed CAS system in RESS procedures.

Main Methods:

  • A prospective study involving 25 RESS procedures utilizing the developed optical CAS system.
  • Comparison with a control group of 10 RESS patients who did not use the CAS system.
  • The same surgeon performed all operations in both groups.

Main Results:

  • The CAS system demonstrated a clinical inaccuracy of 0.5 to 2 mm.
  • No minor or major complications were reported in either the CAS group or the control group.
  • The navigation system effectively aided surgeons in identifying challenging anatomical landmarks.

Conclusions:

  • The optical CAS system serves as a valuable tool for RESS, improving intraoperative safety and anatomic guidance.
  • The system helps mitigate surgeon stress by facilitating the visualization of difficult-to-see structures.
  • CAS technology shows promise in enhancing the precision and safety of revision endoscopic sinus surgery.
