Overview
Microvascular Decompression (MVD) is a surgical procedure that relieves abnormal compression of a cranial nerve. It is performed to treat trigeminal neuralgia, vagoglossopharyngeal neuralgia, and hemifacial spasm. These conditions are often caused by an artery or vein compressing the nerve root as it leaves the brainstem. When compressed, normal nerve impulses can recruit nearby nerve fibers and send faulty messages. Medications often provide relief to patients with these conditions, but when medications become ineffective or cause serious side effects, one treatment option is MVD.
What is MVD?
MVD is a surgical procedure to relieve the symptoms (pain, muscle twitching) caused by compression of a nerve by an artery or vein. MVD involves surgically opening the skull (craniotomy) and exposing the nerve at the base of the brainstem to insert a tiny sponge between the compressing vessel and the nerve. This sponge isolates the nerve from the pulsating effect and pressure of the blood vessel.
Trigeminal neuralgia is an irritation of the fifth cranial nerve causing severe pain that usually affects one side of the face, normally in the forehead, cheek, jaw, or teeth (Fig. 1). To treat trigeminal neuralgia, a sponge is placed between the trigeminal nerve and the superior cerebellar artery or a branch of the petrosal vein. By removing the compression, the painful symptoms are relieved.
Who is a candidate for MVD?
You may be a candidate for MVD if you have:
* trigeminal neuralgia that is not well controlled with medication and you desire minimal to no facial numbness that may be associated with other treatments such as percutaneous stereotactic radiofrequency rhizotomy (PSR) or glycerol injection
* facial pain isolated in the ophthalmic division or in all three trigeminal divisions
* facial pain recurrence after a previous percutaneous or radiosurgery procedure
Because MVD involves the use of general anesthesia and brain surgery, patients with other medical conditions or who are in poor health may not be candidates. MVD is not successful in treating facial pain caused by multiple sclerosis. Because of the low risk of hearing loss, MVD may not be suitable for patients who have hearing loss in the other ear.
MVD Surgical Risks:
- Surgical Wound Infection with Lasting Pain, including menengitis.
- Cerebral Spinal Fluid Leaks
- Anesthesia Dolorosa -- burning pain underlying facial tactile numbness
- Parasthesia -- an itchy, crawly sensation combined with surface numbness
- Facial Numbness -- loss of sensation without other sensory effects
- Partial Facial Paralysis
· Loss of Hearing (rare, and only with MVD)
· Loss of the Tearing Reflex of the Eye, with a Risk of Ulceration to the Cornea (also MVD)
· Surgical Adhesions and Arachnoiditis
· Central Nervous System Fluid Leak (rare, and only with MVD)
· Differentiation Pain (caused by surgical interruption of connections between peripheral nerve endings and the central nervous system).

I had my MVD surgery performed by Dr. Sekula, in February 2009. It was the best decision I have ever made!! My surgery was a success and my recovery complication free. Overall, since the surgery I have lived pain free . On a few occasions, I thought the TN pain had returned however, my history is complicated, as I also suffer from occipital neuralgia and cluster headaches. Dr. Sekula, is respectful and very thorough. He is patient centered direct, and very responsive. His care and level of skill renewed my faith and confidence in the medical community. Prior to surgery, I could not imagine living the life I do today! If you have not had your surgery or if you would like to talk with me, please feel free to contact me. I would be happy to talk with you. Peace and blessings sent your way.
Has anyone had three MVDs? I would like to know the outcome for you from the third time if it has produced better success than the first two.
Anybody have surgery with Dr. Sekula?
Not sure if I should say this with so many people getting ready to have an MVD but I can't help myself. When I finally saw a Neurosurgeon I was so niave. I believed what they said, I was confident they knew what they were doing. They didn't and I ended up with anesthesia dolorosa (double whammy). Now as I read the comments I get in to the what ifs.....what if I didn't have the MVD. I would only be in half the pain and have a life. I hope that it turns out well for you. A very big decision with so many risks.
Melodye,
I'm so sorry to hear your pain is back. I had my MVD shortly after you did.

I had my MVD on March 16, 2010. I was pain-free until May 7, 2011. It was wonderful! Unfortunately the pain is back with a vengeance. I am on 450 mg of triliptal every day. It works sometimes. This is the hardest thing I've ever been through. I also have multiple sclerosis. Some of my TN pain is MS related. The pain is going to undo me.
I do not regret having my MVD because I was pain-free for a little over a year. However, I do not think I will go through it again.
BTW, Bob Homerin, about the Mayo clinic in MN; I was looking into going there myself (I am out of state but grew up in MN and have a lot of respect for the Mayo), but they wouldn't see me if I've been on pain meds (opiates, etc) in the past 3 months.
However, when I was looking into the process, I found out if you just show up at the door, they have to "take the case" as it were, but they can make you wait up to a week to be seen, but that sure beats the indefinite waiting for them to review your case, waiting lists, etc. I didn't go that route myself (this was before I was diagnosed with TN and was desperate to figure out this "mystery"), but was awfully close to heading out to MN.
Though, one thing to be careful of with the Mayo is about insurance, they will often do procedures, etc before checking to see if they are covered, so I would check yourself first before heading over there.
