Full Definition
Tractotomy is a neurosurgical procedure that involves the selective sectioning or interruption of specific white matter fiber tracts in the brain. This technique is used to treat various conditions including chronic pain syndromes, movement disorders, and certain psychiatric conditions. Modern tractotomy procedures often utilize advanced imaging techniques and stereotactic guidance to precisely target pathological neural circuits while preserving normal brain function. Examples include anterior cingulotomy for psychiatric disorders and trigeminal tractotomy for facial pain.
Usage
Usage note: Specify the tract targeted (e.g., cingulum, trigeminal tract) in surgical documentation.
