Multiple Subpial Transections (MST)

Multiple Subpial Transection is a surgical approach for patients with well-localized epileptogenic areas which are unresectable due to their functional importance. This procedure aims to sever horizontal intracortical fibers that are presumed responsible for spreading seizure activity while preserving the other fibers that control neurologic function.
