Sub-occipital approach for implantation of recording multi-electrodes over the medial surface of the temporal lobe.
Recording the electrical activity from the medial aspects of the temporal lobe, including uncus and hippocampal convolution, has an important role in the preoperative evaluation of patients with drug-resistant temporal lobe epilepsy. We report our experience with subdural cylindrical multi-electrodes placed along the medial, basal and lateral aspects of the temporal lobe through a suboccipital approach. Eight patients have been examined with this technique for 3 to 8 days. The quality of the recordings was excellent. No displacement of the electrodes has been noticed. One patient developed meningitis which was successfully treated. The electrodes have been kept in place until surgery and have served as useful landmarks for the resection enabling also neurophysiological monitoring throughout the operation.
