Despite a systematic and multidrug treatment, about 6–10% epileptic patients continue to present epileptic seizures. This is the so-called drug-resistant epilepsy. Authors discuss currently available surgical epilepsy treatment. Potential candidates are patients with focal epilepsy and epileptogenic foci which may be removed without causing new neurological deficits. We present diagnostic techniques enabling precise location of focus within the brain (Holter EEG, videometry, telemetry, digital EEG, MRI, SPECT, PET, electrocorticography). We also show the types of neurosurgical procedures used in epilepsy therapy: procedures of resection (lobectomy, lesionectomy, hemispherectomy, extensive multilobar resection), procedures of disconnection (callosotomy) and procedures of neurostimulation (vagus nerve stimulation, deep brain stimulation). We consider these methods might be of benefit in a selected group of patients with drug-resistant epilepsy.
