![]() Intraoperative neurophysiological monitoring (IONM) is nowadays another tool within the operating room that seeks to avoid neurological sequels derived from the surgical act.

A useful method to monitor motor functions in mini-invasive neurosurgery was described. This report describes a valuable scheme making use of as many electrophysiological signals as possible to constantly monitor the motor functions. ![]() Intraoperative neurophysiology has a great value in mini-invasive neurosurgery, especially because the motor cortex is not exposed, consequently it cannot be directly mapped. Four patients had transient worsening of the symptoms, but only two had a long-term worsening, although not severe, of the pre-op clinical status. SSEP guided the positioning of the strip electrode over the motor cortex (N20 phase inversion) that was used to evoke dMEP and monitor the lower limb motor responses subcortical stimulation to unveil the spatial relationship between the tumors and motor fibers. The recording of all the electrophysiological signals was possible in all procedures. Monitoring consisted in simultaneously recording EEG, electrocorticography, transcranial and direct motor evoked potentials (tMEP and dMEP), somatosensory evoked potentials and subcortical stimulation during the whole procedures. Pre-operative assessment included fMRI scans and tractography that were uploaded into the intraoperative neuro-navigation system. Twenty-one patients were operated under general anaesthesia with the aid of multimodal intraoperative neurophysiological monitoring to remove supratentorials tumors closely related to the cortico-spinal tract. To evaluate the role of intraoperative neurophysiological monitoring in image-guided mini-invasive neurosurgery. Intraoperative neurophysiological monitoring of the cortico-spinal tract in image-guided mini-invasive neurosurgery.Ĭordella, Roberto Acerbi, Francesco Broggi, Morgan Vailati, Davide Nazzi, Vittoria Schiariti, Marco Tringali, Giovanni Ferroli, Paolo Franzini, Angelo Broggi, Giovanni
