OBJECT Idiopathic trigeminal neuralgia (iTN) is a neurological condition treated with pharmacotherapy or neurosurgery. There is a lack of comparative papers regarding the outcomes of neurosurgery in patients with iTN. The objective of this study was to investigate sensory thresholds and masticatory function in 78 patients with iTN who underwent(More)
OBJECT The purpose of this paper was to define the general efficacy of and morbidity associated with stereoelectroencephalography using modem methods of imaging and to particularize the risks related to specific lobes of the brain. METHODS All patients admitted to the Montreal Neurological Institute who had undergone either computerized tomography- or(More)
Today, hemispherectomy is a well-established procedure for the treatment of some sorts of catastrophic epilepsies. This, however, has not always been the case. The technique was developed to deal with brain tumors; however, the initial results were not remarkable. Moreover, when its morbidity became evident, it was almost abandoned. Had it not been for a(More)
OBJECTIVE The objective of this paper is to evaluate factors of surgical morbidity from different techniques of hemispherectomy with emphasis on causative pathology. PATIENTS AND METHODS Thirty patients underwent hemispherectomy in our institution from 1987 to 2003, two presented with Sturge-Weber Syndrome (SWS), sixteen with Rasmussen's Syndrome (RS),(More)
This review focuses on some historical highlights of the surgery of epilepsy, beginning with the reports of Horsley, Krause, and Cushing to which appeared in 1909, the year that The International League Against Epilepsy (ILAE) was inaugurated. We then outline key contributions from Europe and North America, and examine particularly the evolution of our(More)
PURPOSE A gap of more than a hundred years occurred between the first accounts of mesial temporal sclerosis and recognition of its role in the pathogenesis of psychomotor seizures. This paper reviews how the understanding and surgical treatment of temporal lobe epilepsy developed, particularly from the work of Penfield, Jasper, and their associates at the(More)
The concept of a functional cerebral localization gave the needed support for the development of neurosurgery as a specialty. It should be noted though that the presence of functions on discrete areas of the cortex was a very controversial topic at that time. The objective of this paper is to review models of cortical organization at the end of the 19th(More)
BACKGROUND Tentorial meningiomas represent about 5% of intracranial meningiomas. This article reviews our recent institutional series of patients with tentorial meningiomas, proposes a simplified classification and analyzes postoperative evolution, discussing the salient features in the management of these patients. METHODS From 1998 to 2005, 30 patients(More)
BACKGROUND The purpose of this article was to assess if high-risk, mildly head-injured patients with normal CT scan present an outcome similar to the group with "low-risk MHI." METHODS A total of 379 hospital charts of inpatients with Glasgow Coma Scale scores of 13, 14, and 15 were reviewed. Information regarding age, fGCS, trauma mechanism, cranial CT(More)
