Summary
This review explores virtual reality (VR) and intraoperative mapping to prevent visual pathway damage during parietal glioma surgery. These techniques aid in preserving vision by mapping critical brain areas during awake craniotomy.
Area of Science:
- Neurosurgery
- Neuro-oncology
- Medical Technology
Background:
- Parietal gliomas are common primary brain tumors.
- Surgical resection is the gold standard treatment.
- Parietal lobe surgery risks visual pathway complications.
Purpose of the Study:
- Summarize techniques to prevent visual pathway complications during parietal glioma resection.
- Focus on virtual reality (VR) headsets and awake surgery.
- Evaluate VR and intraoperative mapping for preserving optic radiations.
Main Methods:
- Literature review of Medline database (1970-2024).
- Included studies: awake craniotomy, sensory mapping, English, human subjects.
- Excluded: deep brain stimulation, commentaries, reviews.
Main Results:
- Intraoperative ultrasound is accessible and affordable for monitoring.
- MRI-based tractography and VR mapping enable preoperative planning.
- VR and tractography demarcate tumor margins, increasing resection success.
Conclusions:
- Advanced techniques like VR and tractography enhance surgical precision.
- Intraoperative mapping is crucial for preserving visual pathways.
- VR offers a promising tool for minimizing visual deficits in parietal glioma surgery.
