There are several epilepsy surgery technologies but the most common epilepsy surgery is Temporal Lobe epilepsy surgery. Medial temporal sclerosis (MTS) is one of the best-characterized epileptic syndromes. MTS is defined by classical temporal lobe seizures, associated with characteristic temporal spikes on EEG and hippocampal sclerosis identified on MRI. The improvement in seizure frequency after temporal lobectomy is measured by reduced frequency and intensity. Based on the Engel’s classifications, improvement ranges from 60% to 80%. In select populations, seizure-free outcomes of 90% to 100% have been reported.
