Microvascular Decompression

What is a Microvascular Decompression?

Microvascular decompression is a surgery to help with severe pain in your face, throat, or ear, or twitching in your face. It happens when a blood vessel presses on a nerve in your skull, causing problems like sharp pain or muscle spasms. The surgery moves the blood vessel away from the nerve to stop the irritation. The surgeon makes a small cut behind your ear to perform a craniotomy (a way of creating an opening into the skull to access the brain), the surgeon uses a microscope to reach the nerve. They place a soft material, like felt, between the nerve and blood vessel to stop the pressure. This surgery has a high success rate, helping up to 80-85% of patients.

Characteristics of Microvascular Decompression

Patients needing this surgery often have severe symptoms that don’t improve with medicines or Botox injections. The procedure involves:

  • A small cut behind the ear and a small opening in the skull (about the size of a 50-cent coin).
  • Using a microscope to carefully move the blood vessel away from the nerve.
  • Placing a soft material to cushion the nerve and stop the blood vessel from pressing on it.
  • Closing the skull with tiny screws, plates, or bone cement, and stitching the skin.

This surgery needs a general anaesthetic, and you’ll stay in hospital for a few days to recover.

How Do I Know if I’m Experiencing Common Peroneal Nerve Compression?

You might have a problem with your shunt if you notice:

If you have any of these signs, contact your doctor, surgeon, or go to the nearest emergency department right away.

A healthcare professional can provide a comprehensive evaluation, typically involving:

  • Medical history: Your doctor will ask about your symptoms, when they started, and what makes them worse.
  • Physical exam: They’ll check your face, ears, and throat for signs of nerve problems.
  • Imaging tests: Scans like an MRI or CT to see the nerves and blood vessels in your skull.
  • Nerve tests: Tests to check how your nerves are working.

Your doctor may refer you to a specialist, like a neurosurgeon, to discuss if microvascular decompression is right for you. They may also discuss the alternatives with you. If you’re worried about any symptoms, contact your doctor or visit a hospital for advice.

If these medications are not stopped, then your surgery may need to be delayed and rescheduled for reasons of safety. If you are unsure about whether you need to stop any of your medications, please ask your doctor.

Depending on your general fitness and your medical co-morbidities, you may require an assessment by physician specialists and an anaesthetist to assess your safety for surgery, before a decision can be made about your suitability for surgery.

Prior to any surgery, you will need to fast. On the night prior to surgery, your last mouthful of food should be prior to 12 midnight. On the day of surgery, you can sip clear water up until 4 hours prior to your surgery. You may use this opportunity to take medications that your doctor is happy for you to take. Please check with your doctor, what you should do with your medications and write those instructions here.

A member of staff from the hospital or the surgeon’s rooms will contact you up to three days prior to your admission and discuss this with you. They will also discuss your hospital paperwork if this has not been done. This is your opportunity to ask any questions you may have about your upcoming admission.
