Preoperative evaluation for epilepsy surgery (Bonn Algorithm).
Epilepsy surgery has been established as a successful treatment in patients with drug-resistant focal epilepsies. Different standardized surgical approaches were developed for resective or functional treatment. Successful surgical treatment, however, necessitates a careful presurgical evaluation. Although there are international standards for non invasive and invasive presurgical procedures most centers differ in their diagnostic strategy. This article gives a survey of the Bonn Epilepsy surgery program within which more than 1300 patients have been treated. After the method of patient selection different we describe tools of non invasive and invasive evaluation. This article serves only as a description of current practice in one center with a relatively large volume of cases. It presents just one opinion of a specific group within a wide spectrum of possible algorithms for presurgical evaluation that have briefly been outlined for 33 centers in Engels book [4].
