Rationale: Stereo-electroencephalography is a powerful tool to map and localize epileptogenic networks and zones in patients with medically intractable epilepsy. The conventional technique requires placement through native bone but this may be technically challenging in multiple patient subpopulations with non-autologous cranioplasties. We describe a novel technique to successfully place SEEG electrodes in three patients without native bone.
Methods: We describe three cases. The first is a 30-year-old male who underwent a left pterional craniotomy for aneurysm clipping with a titanium mesh cranioplasty. The second is a 51-year-old female who previously underwent lesionectomy of a ganglioglioma and subsequent recurrence of her seizures with a mesh cranioplasty. Finally, the third is a 31-year-old male who underwent decompressive hemicraniectomy for trauma with a PEEK cranioplasty.
Results: Our SEEG placement technique through non-autologous cranioplasty was successful without complication and allowed for excellent EEG recording and optimal localization of the seizure focus. We encountered no unexpected technical challenges due to the cranioplasty.
Conclusions: Placement of SEEG electrodes through non-autologous cranioplasties was clinically feasible, safe, and effective in our series. The presence of non-autologous bone cranioplasty should not preclude such patients from undergoing SEEG explorations.
