DREZotomy is a procedure that destroys the dorsal root entry zone and thereby providing pain relief by blocking the pain pathway in selected spinal cord segments. Sindou, et al. initially described this for a patient with a Pancoast tumor invading the brachial plexus.[1] Since then, the procedure was modified and applied. This ablation can be achieved through multiple methods like bipolar coagulation, radiofrequency/laser ablation, micro scissors[2]/surgical scalpel, and ultrasonic ablation. The literature reports that DREZotomy is more successful in patients with brachial plexus avulsion injuries.[1],[3] The principle behind all these procedures is to destroy the affected spinal cord segments' dorsal root entry zone. Newer treatment methods include modulating the dorsal root ganglion through the DRG stimulator without destroying the dorsal root entry zone.[4]
Long term results of DREZotomy showed to achieve adequate pain control in 88% of patients suffering from predominant paroxysmal pain and 20% in continuous pain[5]. In this illustration, we intend to show different methods to ablate the dorsal root entry zone, to alleviate the pain.
