[Use of stereotaxic method in combination with classic craniotomy in treatment of focal epilepsy].

A new method of surgical treatment in dealing with severe forms of multifocal epilepsy-stereotaxic intervention on subcortical structures during open craniotomy--is proposed. The method allows stereoelectrographic 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.
