Dorsal root entry zone (DREZ)

A type of nerve surgery for postherpetic neuralgia that is occasionally used when the patient can get no other pain relief. The surgery destroys the area where damaged nerves join the central nervous system, thereby interfering with inappropriate pain messages from nerves to the brain.

Sometimes, a surgical procedure such as dorsal root entry zone (DREZ), rhizotomy, or cordotomy is recommended, in which incisions are made in select nerve locations to interrupt the pain in the nervous system itself.

Some of the advances we have made include the analysis and characterization of the electrical "signature" of normal SCI tissue, impaired tissue, dying tissue, and dead tissue, and improvements in the Computer-Assisted Dorsal Root Entry Zone Microcoagulation (CA-DREZ) procedure.
