Routine EEG telemetry using scalp electrode recordings is carried out in all patients being considered for epilepsy surgery. However this, along with other testing, may not yield sufficient information about the location of seizure onset to allow a decision regarding surgery to be made. Various methods have been developed to implant electrodes for chronic recording closer to the cortical surface from which seizures arise including the use of sphenoidal, foramen ovale, epidural peg, subdural and depth electrodes. This is a review of the last two techniques particularly as utilized at London Health Sciences Centre.

Résumé

RÉSUMÉ

L'enregistrement ÉEG par télémétrie au moyen d'électrodes appliquées sur le cuir chevelu est fait de routine chez tous les patients évalués en vue d'une chirurgie de l'épilepsie. Cependant cet enregistrement, ainsi que les autres tests effectués, ne fournissent pas toujours suffisamment d'information sur le site où les crises prennent naissance pour permettre de prendre une décision concernant la chirurgie à effectuer. Différentes méthodes ont été développées pour implanter des électrodes afin de procéder à un enregistrement prolongé plus près de la surface corticale au site où les crises prennent naissance dont l'utilisation d'électrodes sphénoïdales, d'électrodes du trou ovale, d'électrodes épidurales PEG, d'électrodes sous-durales et d'électrodes profondes. Nous revoyons l'utilisation de ces deux dernières techniques au London Health Sciences Centre.
