Comparison of Different Computer-Aided Surgery Systems in Skull Base Surgery
1Department of Otolaryngology, Head and Neck Surgery, Mainz University Medical School, Mainz, Germany.
Summary
Computer-aided surgery (CAS) systems enhance precision in ENT procedures when anatomy is unclear. VectorVision(R) and InstaTrak(R) demonstrated suitability for routine use in sinus and skull base surgeries.
Area of Science:
- Neurosurgery
- Otolaryngology
- Medical Imaging
Background:
- Computer-aided surgery (CAS) systems utilize high-resolution imaging for intraoperative guidance, particularly when anatomical landmarks are compromised.
- Various commercial CAS systems employing optical or electromagnetic navigation are available for surgical applications.
Purpose of the Study:
- To evaluate the practical application and performance of EasyGuide(R), VectorVision(R), and InstaTrak(R) CAS systems in Ear, Nose, and Throat (ENT) surgery.
- To assess system accuracy, time efficiency, handling, and overall practicality in both laboratory and clinical settings.
Main Methods:
- A comparative study involving 155 patients undergoing endonasal sinus surgery and 23 patients undergoing anterior or lateral skull base procedures.
- Evaluation of three CAS systems: EasyGuide(R), VectorVision(R), and InstaTrak(R), focusing on accuracy, time, handling, and features.
Main Results:
- VectorVision(R) and InstaTrak(R) CAS systems were found suitable for routine application in ENT surgery.
- These systems aided in avoiding critical structures and facilitated minimally invasive approaches in paranasal sinus and anterior skull base surgeries.
Conclusions:
- CAS systems, specifically VectorVision(R) and InstaTrak(R), offer significant benefits for complex ENT procedures.
- Their application can improve surgical precision, safety, and efficiency in navigating challenging anatomical regions.
