ABSTRACT

Introduction: The main objective of epilepsy surgery is to provide maximum seizure-free time, not to add neurological deficit and decrease of antiepileptic drugs. Material and methods: A total of four cerebral hemispheres prepared with the Kingler technique were studied. Results: Measurements were made of the distances of the cortical surface in the frontal lobe between F2 and F3 to the superior longitudinal fasciculus being 19 ± 1.82 mm; of the cortical surface of the posterior portion of the superior and middle temporal gyrus with the vertical tract of the superior longitudinal fasciculus was 21 ± 1.41 mm; of the cortical surface of the posterior prefrontal and temporal region with the arcuate segment of the superior longitudinal fasciculus is 24.25 ± 1.5 mm. The average distance to the cortical portion of T2 was 18.75 mm ± 0.957, the distance from the temporal pole to the anterior edge of the Meyer beam is 29.5 ± 1.29 mm; the length of the optical radiation is 94.5 ± 1.29 mm. Conclusions: Knowledge of white matter fibers is important to prevent lesions in different approaches to the mesial temporal region and thus optimize the functional outcome of surgery.
