Three-dimensional reconstruction and surgical navigation in padiatric epilepsy surgery
We have used MRI-based three-dimensional (3D) reconstruction and a real-time, frameless, stereotactic navigation device to facilitate the removal of seizure foci in children suffering from intractable epilepsy. Using this system, the location of subdural grid and strip electrodes is recorded on the 3D model to facilitate focus localization and resection. Ten operations were performed — two girls and eight boys ranging in age from 3–17 — during which 3D reconstruction and surgical instrument tracking navigation was used. In all cases, the patients tolerated the procedure well and showed no post-operative neurological deficits.
