Stereotactic and Functional Neurosurgery

Stereotactic and Functional Neurosurgery is a highly specialized neurosurgical discipline focused on the precise targeting of deep brain structures to treat movement disorders, epilepsy, chronic pain, and psychiatric conditions. Presented at a global Surgical Science Conference, this session explores image-guided targeting systems, neuromodulation therapies, and evolving advancements in functional brain surgery. By combining advanced neuroimaging with minimally invasive techniques, this field enables highly accurate interventions while preserving surrounding neural pathways.

Stereotactic surgery relies on three-dimensional coordinate systems derived from MRI and CT imaging to localize specific brain targets. Frame-based and frameless navigation systems guide the placement of electrodes or lesioning probes with millimeter accuracy. Deep brain stimulation has emerged as a cornerstone therapy for conditions such as Parkinson’s disease, essential tremor, dystonia, and certain psychiatric disorders. Implantation of programmable electrodes allows controlled electrical modulation of abnormal neural circuits.

Functional neurosurgery also includes procedures such as radiofrequency ablation, laser interstitial thermal therapy, and focused ultrasound for lesion creation in selected cases. Epilepsy surgery involves careful mapping of seizure foci and selective resection or neuromodulation to reduce seizure frequency while preserving cognitive function. Intraoperative neurophysiological monitoring and microelectrode recording enhance targeting precision.

Pain management applications include spinal cord stimulation and motor cortex stimulation for chronic neuropathic pain syndromes. Advances in brain–computer interface research and adaptive stimulation technologies are expanding therapeutic possibilities. Careful patient selection, multidisciplinary evaluation, and long-term programming adjustments are critical for optimal outcomes.

Postoperative follow-up focuses on device calibration, symptom monitoring, and neurological assessment. Collaboration between neurosurgeons, neurologists, psychiatrists, and rehabilitation specialists ensures comprehensive care.

By integrating high-resolution imaging, neurophysiologic mapping, and programmable neuromodulation systems, stereotactic and functional neurosurgery continues to redefine therapeutic precision in the treatment of complex neurological disorders.
