About the Procedure
What is a Bulbar Dorsal Root Entry Lesion Procedure?
Bulbar dorsal root entry zone (DREZ) lesioning is a surgical procedure that involves making a lesion in the dorsal root entry zone of the spinal cord in the medulla oblongata, which is located in the brainstem. This procedure is typically performed to relieve severe pain associated with neurological conditions that affect the head, face, or neck, such as trigeminal neuralgia, glossopharyngeal neuralgia, or spasmodic torticollis.
​
Before the procedure:
Before the surgery, you will meet with your surgeon and medical team to discuss the procedure and ask any questions you may have. You may need to stop taking certain medications, such as blood thinners, and fast for a certain period of time before your surgery. Your surgeon will provide you with detailed instructions on how to prepare for your procedure.
​
During the procedure:
The bulbar DREZ lesioning procedure is typically performed under general anesthesia. The surgeon will make a small incision in the back of the neck to access the medulla oblongata. They will use a high-powered microscope to locate the specific nerves responsible for the patient's pain. The surgeon will then make a small lesion in the dorsal root entry zone of the affected nerves to interrupt the transmission of pain signals.
​
After the procedure:
After the surgery, you will be closely monitored in the recovery room until you are awake and stable enough to be moved to a hospital room. You may need to stay in the hospital for several days to a week or more, depending on the specifics of your surgery. Your surgeon will provide you with detailed instructions on how to care for your incision, manage any pain or discomfort, and gradually resume your normal activities.
