Surgery of central sensory motor and dorsolateral frontal lobe seizures.
Ten patients who presented with dorsolateral or frontocentral seizures were studied with chronic subdural grid electrodes. Cortical mapping, sensory-evoked potentials and chronic electrocorticography were obtained for each patient. Seizures were classified as focal, regional or dipolar. At the time of explanation, a selective functional corticectomy was performed. Surgical outcome is presented at a mean follow-up of 36 months. Two patients are seizure-free and 7 patients had a significant reduction in seizure frequency. One patient had no change in seizure pattern. Dorsolateral frontal lobe seizures have a focal functional anatomy and can be surgically treated by selective cortectomy.
