Summary
Motor cortex stimulation (MCS) offers an alternative treatment for central pain syndromes. Image guidance, including neuronavigation and a vacuum headrest, proved effective and safe for electrode placement, providing pain relief in all patients.
Area of Science:
- Neurosurgery
- Pain Management
Background:
- Motor cortex stimulation (MCS) is an emerging treatment for central pain syndromes.
- Minimally invasive surgical techniques are crucial for improving patient outcomes.
Purpose of the Study:
- To present a minimally invasive technique for motor cortex stimulation (MCS) electrode placement using image guidance.
- To assess the clinical utility of neuronavigation and a vacuum headrest in MCS surgery.
Main Methods:
- Five patients with central pain underwent MCS using a frameless stereotactic system (BrainLab AG).
- Neuronavigation guided precentral gyrus identification and single burr hole planning.
- Intraoperative stimulation confirmed electrode location; postoperative evaluations assessed outcomes.
Main Results:
- The navigation system functioned correctly in all five cases.
- Accurate placement of the stimulating electrode was achieved in all patients.
- All patients experienced postoperative pain relief with no surgical complications.
Conclusions:
- Image guidance is a valuable tool for motor cortex stimulation (MCS) surgery.
- A single burr hole and vacuum headrest enable minimal and safe surgical exposure.
- This technique provides effective pain relief for central pain syndromes.
