Abstract
In the case of resection of gliomas involving eloquent areas, equal consideration should be given to maintain maximal extent of resection (EOR) and neurological protection, for which the intraoperative neuromonitoring (IONM) proves an effective and admirable approach. IONM techniques applied in clinical practice currently consist of somatosensory evoked potential (SSEP), direct electrical stimulation (DES), motor evoked potential (MEP), electromyography (EMG), and electrocorticography (ECoG). The combined use of DES and ECoG has been adopted widely. With the development of technology, more effective IONM tactics and programs would be proposed. The ultimate goal would be strengthening the localization of eloquent areas and epilepsy foci, reducing the incidence of postoperative dysfunction and epilepsy improving the life quality of patients.
Highlights
Glioma is the most common type of primary intracranial tumors and accounts for ∼30% of them
As surgical operations are often accompanied by the risk of instant acute partial injuries to eloquent areas, the balance between maximal extent of resection (EOR) and neurological protection is always unmanageable
The results showed that the combination of 5-ALA and contrast-enhanced ultrasound significantly improved the EOR compared with conventional strategy [1]
