Intraoperative neuro-monitoring is one of the minimally invasive neurosurgery techniques to reduce the risk of intraoperative damage to the nervous system, thereby reducing the risk of postoperative neurological deficits.
Neuro-monitoring consists on the intraoperative recording of the activity of the nervous system.
Several recordings technics can be made: somatosensitive evoked potentials (SEP), motor evoked potentials (MEP), EMG, electrocorticography, auditory evoked potentials (AEP), and brainstem evoked potentials, the study of the D wave.
We report our preliminary experience and discuss the value of these recordings technics in neurosurgery.
The series include thirty-six cases: twenty cases of awake surgery for low-grade glioma in or near the eloquent areas, four scoliosis, two spina bifida, two traumatic cervical spines, two cases of cervical disc herniation, one lumbar neuroma, one case of facial hemi-spasm, one case of acoustic neuroma, two spinal cord tumors and one rolandic cavernoma.
Our department will continue to develop these technics in order to make our neurosurgical procedures more safe and we will insist on the multidisciplinary nature of these procedures.
