What Is Microvascular Decompression?
Microvascular decompression (MVD) is a specialized neurosurgical procedure that relieves severe facial pain caused by trigeminal neuralgia-a condition resulting from abnormal compression of the trigeminal nerve by nearby blood vessels.
Patients with trigeminal neuralgia often experience:
- Sudden, sharp facial pain
- Discomfort in the cheek, jaw, teeth, or forehead
- Episodes triggered by mild touch, chewing, or talking
- Occasionally, facial spasms or weakness
This condition is typically caused when a loop of an artery or vein presses against the trigeminal nerve root, sending abnormal pain signals to the brain. When medications no longer control symptoms effectively, microvascular decompression surgery can provide lasting relief. Microvascular decompression is one of several advanced surgical approaches available for complex neurological conditions and treatment options involving nerve compression.
How Microvascular Decompression Works
Microvascular decompression is performed under general anesthesia by a board-certified neurosurgeon experienced in cranial nerve surgery.
Step-by-step Overview:
- A small craniotomy (opening) is made behind the ear.
- The surgeon carefully exposes the trigeminal nerve under a high-powered surgical microscope.
- A tiny Teflon® pad or similar material is gently placed between the nerve and the offending blood vessel.
- This separation eliminates direct contact, reducing or eliminating pain signals.
- The incision is closed, and patients are typically monitored overnight.
Most patients notice immediate pain relief after surgery. Hospital stays are usually 1–2 days, and recovery takes a few weeks with gradual return to normal activities.
Benefits of Microvascular Decompression
Compared to other surgical treatments for trigeminal neuralgia (such as rhizotomy or radiosurgery), MVD offers distinct advantages:
- Addresses the root cause of nerve compression
- Preserves nerve function-no facial numbness or loss of sensation
- High success rate with long-term pain relief
- Quick recovery and minimal scarring
Who Is a Candidate for MVD?
Microvascular decompression may be recommended for patients who:
- Have classic trigeminal neuralgia confirmed by MRI or imaging
- Experience limited relief or side effects from medication (e.g., carbamazepine or oxcarbazepine)
- Are in good overall health and can safely undergo anesthesia
Your neurosurgeon will conduct a thorough evaluation, including a review of your medical history, imaging studies, and response to prior treatments, before recommending MVD.
Recovery and Aftercare
After surgery, patients typically:
- Spend 1–2 nights in the hospital for observation
- Experience mild headache or fatigue for several days
- Are advised to avoid heavy lifting or strenuous activity for 3–4 weeks
Most patients return to normal routines within a month, often with complete or significant pain relief.

Frequently Asked Questions (FAQs)
Q: What causes trigeminal neuralgia?
A: It’s most often caused by a blood vessel pressing on the trigeminal nerve, leading to abnormal pain signals. In rare cases, it may result from multiple sclerosis or a tumor.
Q: How successful is microvascular decompression?
A: Studies show that 80–90% of patients experience long-term pain relief after MVD, especially when performed by experienced neurosurgeons.
Q: Is microvascular decompression risky?
A: As with any brain surgery, risks exist but are low when performed by skilled neurosurgeons. Most patients recover well with minimal complications.
Q: How long does recovery take?
A: Most patients resume light activities within 2–4 weeks and feel fully recovered within 6–8 weeks.
Q: Do I need a referral?
A: No referral is required for most appointments. Contact our office to confirm insurance requirements.
