A lead fixation accessory configured to be positioned over a skull hole and to transition between an opened state and a closed state during a lead implant procedure protects against lead migration by providing a mechanism for securing the lead in place at the skull hole while a stylet is removed from the lead. The lead fixation accessory remains in place after the implant procedure to provide chronic lead stability. A lead stabilization tool configured to access and grip a lead through a slotted cannula during the lead implant procedure also protects against lead migration by providing a mechanism for securing the lead in place at a point where the lead exits the skull hole while the slotted cannula is removed from the skull hole and peeled away from the lead.
