Surgery for frontal lobe epilepsy

Frontal lobe epilepsy makes up between 20 and 30% of all partial epilepsies and is the biggest subgroup of the extratemporal lobe epilepsies. Of the patients who undergo surgery for epilepsy up to 18% have a frontal lobe focus. The aetiology of frontal lobe epilepsy is varied, clinical semiology is diverse and seizures are often frequent, disabling and refractory to treatment. Imaging and EEG findings are often non-localising therefore patients who undergo surgical evaluation for frontal lobe epilepsy require extensive and often-invasive diagnostic investigations1–7.
