The basic aim of any neurosurgical procedure is to remove the pathological lesion as tumor without affecting the surrounding healthy nerual tissues. The location of some tumors is in very close proximity to the nerves like intramedullary spinal cord tumors, cerebellopontine angle tumors as acoustic schwanommas. Continuous or intermittent monitoring is done during surgical excision of these tumors.
This modality is used most commonly during surgery for intramedullary spinal cord tumors and acoustic schwanommas. It gives a continuous real time feedback about the status of the adjacent intact neural tissues. Any subtle surgical effect is picked up. It directs the surgeon to be careful in the particular area and to modify the approach.
Using this equipment results in good neurological, clinical and functional outcomes.
