What does the bilateral STN DBS implantation procedure involve?

This procedure involves stereotactically implanting thin electrodes into the subthalamic nucleus (STN) on both sides of the brain, followed by placement of a pulse generator (similar to a pacemaker) under the skin near the collarbone. The electrodes deliver controlled electrical stimulation to modulate abnormal neural activity, typically for movement disorders like Parkinson's disease. The surgery is performed under local or general anesthesia using MRI-guided targeting for precision, and the device is programmed post-operatively to optimize symptom control.
