Intraoperative neuromonitoring is used to monitor the central nervous system during neurosurgery operations to lower the risk of postoperative problems.
Essential functions, including motor, somatosensory, auditory or visual functions, can be monitored throughout the surgical procedures.
These neurophysiological actions, which are carried out continuously, detect early changes due to modifications of the nervous system that are still reversible. This is to alert the surgeon so that they can adapt their operating strategy to avoid a neurological deficit.
Example of monitoring
Intraoperative neuromonitoring also provides methods to locate functional areas and pathways.
Intraoperative neuromonitoring is used in neurosurgery for resections of brain tumors, epileptic foci, cranial nerves, spinal lesions and for vascular neurosurgery.
In addition, various intracerebral recordings are made for functional neurosurgery (deep brain stimulation, DBS).
The group is developing new techniques for the neuromonitoring of vision, the spinal cord, olfaction and language.
Example of olfactory evoked potentials.
Just as with vision, neuromonitoring of brain areas and pathways is developed for surgery under general anesthesia.
As part of this research, collaborations with the industry allow for specific technology transfers.
