Refractory epilepsy can be defined as a failure of adequate trials of antiepileptic drug programs tolerated and appropriately chosen and used (either as monotherapy or in combination) to achieve sustained freedom from seizures. Surgical procedures for the control of epileptic seizures have spread throughout the world, however, large medical centers have mainly focused on studying and analyzing the clinical results of their surgical interventions. This study is a retrospective, descriptive, quantitative and longitudinal type of a series of patients who underwent hemispherectomy or temporal lobectomy in the Epilepsy Monitoring and Surgery Unit (UMCE) of Costa Rica, between November 2000 and December 2018 to assess whether or not there is an economic saving comparing the amount of anti epileptic drugs they received before surgery with the ones received afterwards.
