Summary
Computer-aided surgery using the Philips "NEUROGUIDE" system is feasible for ENT-sinus procedures. This navigation technology offers precise guidance (1-3 mm) and enhances surgeon orientation during complex sinus surgeries.
Area of Science:
- Otolaryngology
- Medical Imaging
- Surgical Navigation
Background:
- Chronic sinus pathology often necessitates surgical intervention.
- Accurate navigation is crucial for safe and effective sinus surgery, particularly around critical anatomical structures.
Purpose of the Study:
- To evaluate the feasibility, precision, and clinical utility of computer-aided surgery (CAS) in ear, nose, and throat (ENT) sinus surgery.
- To assess the performance of the Philips "NEUROGUIDE" navigation system in this surgical context.
Main Methods:
- Five patients with chronic sinus pathology underwent surgery using the Philips "NEUROGUIDE" system for intraoperative navigation.
- System precision was measured by anatomical landmark accuracy (distance in mm) and root mean square error (RMSE).
Main Results:
- The Philips "NEUROGUIDE" system demonstrated feasibility and provided constant orientation during surgery.
- Precision was achieved within 1 to 3 mm, enabling identification of critical structures.
- Operation time increased by approximately 15 minutes due to system handling.
Conclusions:
- The Philips "NEUROGUIDE" system is a viable technical aid for ENT sinus surgery.
- The system offers reliable precision comparable to other navigation technologies.
- CAS enhances surgical decision-making by providing intraoperative orientation and anatomical reference.
