THE IMPORTANCE OF INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING IN THE SURGERY OF SUBTENTORIAL CEREBRAL PATHOLOGY
Abstract:
Intraoperative neurophysiological monitoring in subtentorital pathology involves structures at
risk such as cranial nerves, especially the facial nerve, trigeminal and vestibulocohlear nerve, but also
the sensory and motor tracts passing through the cerebral trunk. Multimodal monitoring uses auditory,
sensory and motor evoked potentials, as well as spontaneous electromyography and direct nerve
stimulation of motor cranial nerves. The timely correction of changes in some parameters during these
neurophysiological techniques allows for the avoidance of lesions of the nerve structures and thus, of the
occurrence of postoperative neurological deficits.
