What is Microvascular Decompression for Trigeminal Neuralgia?
Microvascular Decompression (MVD) is a surgical procedure aimed at relieving the debilitating pain caused by Trigeminal Neuralgia. This is a very painful condition that may be caused by a blood vessel compressing the trigeminal nerve. MVD involves relocating or removing blood vessels that are in contact with the trigeminal root, aiming to stop the nerve from malfunctioning.
Who is a candidate for Microvascular Decompression for Trigeminal Neuralgia?
Candidates for MVD typically have severe, medication-resistant trigeminal neuralgia. They are generally in good health otherwise, able to undergo anesthesia, and do not have contraindications for surgery. Imaging studies like MRI must confirm vascular compression of the trigeminal nerve.
Preparation for Microvascular Decompression Procedure
Preparation involves neurological evaluations, imaging studies, blood tests, and discussions about the potential risks and benefits. Patients may be advised to stop certain medications and will receive instructions on fasting before the surgery.
What does the Procedure involve?
MVD is performed under general anesthesia. A small incision is made behind the ear on the affected side. The surgeon creates an opening in the skull to access the trigeminal nerve and carefully repositions or removes the offending vessels. The area is then closed with sutures or clips.
Recovery after Microvascular Decompression for Trigeminal Neuralgia
Recovery includes hospitalization for a few days. Most patients experience immediate pain relief after the procedure and it takes about a week for pain and stiffness to resolve. It may take a few weeks before symptoms completely go away. Follow-up appointments are crucial to monitor healing and nerve function.
Risks of Microvascular Decompression for Trigeminal Neuralgia
Risks include bleeding, infection, hearing loss, facial numbness, or weakness. There's also a small risk of stroke or other complications related to brain surgery.
Benefits of Microvascular Decompression for Trigeminal Neuralgia
MVD offers a high success rate in relieving pain and has a low risk of pain recurrence. It does not damage the trigeminal nerve, preserving facial sensation and offering a potential long-term solution without the need for medication.
