DREZ Lesion Surgeon in Kolkata
Overview
DREZ lesioning, also known as DREZ rhizotomy, is a surgical procedure targeting the spinal cord's Dorsal Root Entry Zone (DREZ). This area plays a crucial role in transmitting pain signals to the brain. The procedure aims to disrupt these pain signals, offering relief for specific chronic pain conditions. It is a highly specialised procedure typically considered when other treatments have failed. In Kolkata, Dr. Rohit Mishra is a specialised surgeon who deals with DREZ lesioning treatment.

DREZ Lesioning Procedure
The DREZ procedure typically takes 3-5 hours, depending on the number of nerve root treatments, which involves:
Anaesthesia
The doctor applies general anaesthesia to ensure the patient is completely asleep during the procedure.
Access
The surgeon makes an incision over the appropriate area of your spine. The specific location depends on which nerve roots are causing your pain.
Laminectomy
A portion of the vertebra is removed to access the spinal cord and dorsal nerve roots.
Identifying the target
The surgeon identifies the specific dorsal root entry zones causing your pain.
Creating lesions:
Using a precise instrument (typically radiofrequency, laser or microsurgical techniques), the surgeon carefully creates tiny lesions in the difficult dorsal root entry zones.
Closure
The surgical site is closed in layers with sutures.

Frequently Asked Questions
Who can get DREZ lesioning?
Patients with chronic pain due to brachial plexus avulsion, spinal cord injury pain, or post-herpetic neuralgia that do not respond to medication may benefit from the DREZ lesion procedure.
How effective is DREZ lesioning for neuropathic pain?
DREZ lesioning has a very high success rate. Many patients experience notable pain relief, which may vary depending on individual conditions. The procedure is particularly effective for pain from phantom limbs and spinal cord injuries.
Is DREZ rhizotomy the same as DREZ lesioning?
DREZ rhizotomy is a similar procedure to lesioning but focuses on cutting nerve roots, while DREZ lesioning targets the nerve entry zone for particular pain relief.
Are there any alternative treatments for DREZ Lesioning?
Yes. During the consultation, your doctor may recommend other treatment options, including nerve blocks, spinal cord stimulation, and medication. Your doctor will discuss all options with you.
Is DREZ lesioning a cure for chronic pain?
DREZ lesioning can significantly reduce pain, but it is not always a cure. This treatment process is most effective for specific types of neuropathic pain.
