Summary
Hemispheric transcranial electrical stimulation (TES) effectively monitors the inner capsule during supratentorial surgery, showing high sensitivity and specificity. Changes in motor response during resection can indicate potential neurological injury.
Area of Science:
- Neurosurgery
- Neurophysiology
- Medical Devices
Context:
- Intraoperative neurophysiological monitoring (INM) is crucial for patient safety.
- Transcranial electrical stimulation (TES) is a common INM technique.
- Existing TES methods have theoretical limitations in supratentorial surgery.
Purpose:
- To evaluate the utility of hemispheric TES (C3/C4-Cz) for monitoring the inner capsule during supratentorial neurosurgery.
- To assess the sensitivity and specificity of hemispheric TES in detecting potential neurological compromise.
Summary:
- Hemispheric TES was applied to 15 patients undergoing supratentorial surgery.
- Motor responses in facial, arm/hand, and leg/foot muscles were recorded.
- Stimulation intensity did not impede microsurgical dissection, and observed changes in motor responses correlated with neurological outcomes.
Impact:
- Hemispheric TES demonstrates high sensitivity and specificity for monitoring the inner capsule.
- This technique aids in preventing neurological injury during complex supratentorial procedures.
- Findings support the expanded use of TES in neurosurgical interventions.
