Table 2. A comparison of the clinical benefits and drawbacks between SEEG and SDE implantation.

	SEEG	SDE
Safety	-Lower rates of infection, hemorrhage, neurological deficits, and morbidity	-Increased rates of infection, hemorrhage, neurological deficits, and morbidity
Invasiveness	-Faster procedure -Lower hospital length of stay -Simple electrode removal	-SDE commits patients to two craniotomies
Versatility	-Bilateral hemisphere investigations -Analysis of deeper cerebral tissue -Can record nearly every cerebral structure -Useful for patients with temporal lobe epilepsy, insular epilepsy, hypothalamic hamartoma	-Lacks the extensiveness and scope of SEEG
Efficacy	-Higher rates of seizure control than SDE	-Lower rates of seizure control that SEEG

SEEG: stereoelectroencephalography, SDE: subdural electrode.
