Abstract

Intraoperative application of evoked potentials has evolved over the last thirty years, and somatosensory evoked potential (SSEP) monitoring is the method most commonly employed [1]. The ultimate goal of intraoperative SSEP monitoring is to ensure maintenance of neurologic integrity throughout a procedure with resultant improved outcome and decreased morbidity.
