title: Assessment of surgical outcome.
abstract: Evaluation of outcome of epilepsy surgery is complex because of several factors. Epilepsy is itself a heterogeneous disorder. Different epilepsy centers encounter different referral mixes of patients. Institutions employ various methods for pre-operative evaluation and widely varying surgical techniques. Clear definitions of surgical success and reliable scales for its measurement are lacking. Few data are acquired prospectively and maintained in a format allowing inter-institutional collation of results. A better representation of surgical outcome could in the future be served by adherence to 4 principles: collection of common data in standard formats; comparison of like, rather than disparate, populations; maintenance of quantitative data in raw form; and measurement of outcome along several dimensions or scales. Psychosocial issues have been underemphasized in most prior analyses of outcome.
