| Abstract |
Objective
Precise anatomical recognition of normal structures and minimal damage to the normal brain are two keys of success for surgical resections in brain or spine surgery. Frameless stealth station can help the surgeon to have a better understanding of the spatial geometry of the brain during surgery and can be help ful in brain or spine surgery.
Methods
Preoperatively, nine fiducials were placed on the patient head before performing an MRI with 3 dimensional contiguous axial slices. All the MRI data were down loaded into a UNIX workstation through an ethernet connection. By linking information with the spatial position of the head given by the arc, the workstation can display in real time the position of the head given by the arc, the work station can display in realtine position of the probe on the screen relative to the preoperative MRI. 719 patients was operated with stealth station from August, 15th, 1994 to December, 31st, 2001.
Results
Brain surgery was 685 cases, spine surgery was 34 cases. The brain pathology was brain tumor 487 cases, vascular anomaly 55 cases, other 79 cases. The spine pathology was 7 C1-C2 deformities, 7 spinal stenosis, 5 spinal fractures, etc. Epilepsy surgery was performed in 77 cases. Epilepsy surgery without brain tumor consisted of amygdalohippocampectomy in 46 cases (71.9%), temporal lobectomy in 6 cases (9.4%), et.
Conclusion
Neuronavigation stealethstation is helping the surgeon to identify anatomical landmarks throughout the procedure and minimizing the resection of normal brain. It is useful to deep seathed lesion, eloquent area lesion. Multiple lesion, epilepsy, spine operation. The precision obtained with our system was about 2mm which is precise enough for brain or spine surgery. |
