Summary
Neuronavigation is a valuable tool in cranioorbital neurosurgery for orbital tumors, offering high accuracy and usefulness. This study found it to be a reliable complement to surgical expertise.
Area of Science:
- Neurosurgery
- Ophthalmology
- Medical Imaging
Background:
- The role of neuronavigation in cranioorbital neurosurgery remains debated and under-researched.
- Orbital tumors present unique surgical challenges requiring precise localization and removal.
Purpose of the Study:
- To assess the application, utility, and reliability of neuronavigation in surgically treating orbital tumors.
- To evaluate the effectiveness of frameless, armless, infrared-based neuronavigation systems in cranioorbital procedures.
Main Methods:
- Utilized a frameless, armless, infrared-based neuronavigation system for microsurgical removal of 7 orbital tumors.
- Employed CT, MRI, and image fusion for neuronavigation guidance across different surgical approaches.
- Surgical approaches included extradural fronto-orbital, lateral orbitotomy, trans-supraciliar, and inferomedial orbitotomy.
Main Results:
- All surgical procedures were successful with zero procedure-related morbidity or mortality.
- Neuronavigation registration accuracy ranged from 1.0 to 1.7 mm (average 1.3 mm).
- Image guidance was deemed useful in all cases, with total tumor removal achieved in 5 patients.
Conclusions:
- Neuronavigation is a valuable adjunct, not a replacement, for surgical expertise in cranioorbital surgery.
- The system demonstrated significant intraoperative potential, enhancing precision and outcomes in orbital tumor resection.
