Application with classic craniotomy in the treatment of focal epilepsy

A new method of surgical treatment in dealing with severe forms of multifocal epilepsy--stereotactic intervention on subcortical structures during open craniotomy--is proposed. The method allows stereoelctrographic examinations to be performed during open operative interventions, helps discover subcortical epileptogenic foci, establish functional interrelationship of the chosen subcortical structure and the cortical epileptogenic focus and to undertake a differentiated intervention on the cortical, subcortical and both these foci at the same time.
