Percutaneous Rhizotomy

What is a Percutaneous Rhizotomy?

A percutaneous rhizotomy is a procedure to help manage severe pain in the face, ear, or throat caused by certain nerves. The trigeminal nerve can cause intense facial pain, known as trigeminal neuralgia. The glossopharyngeal nerve can cause pain in the ear or throat, called glossopharyngeal neuralgia. In this procedure, a doctor uses a fine needle to inject a numbing medicine (like glycerol or local anaesthetic) near the affected nerve to reduce pain or confirm a diagnosis. The needle is guided using X-rays or a special computer to ensure it reaches the right spot. A percutaneous rhizotomy is different from a microvascular decompression because it does not require a craniotomy.

Characteristics of trigeminal or glossopharyngeal neuralgia

These conditions are caused by nerves sending pain signals when they shouldn’t. Patients experiencing these conditions often need specialised care, which may involve:

  • Pain relief medications prescribed by a doctor
  • Procedures like percutaneous rhizotomy to block pain signals
  • Surgery to separate  a blood vessel away from the nerve (craniotomy, microvascular decompression)
  • Gamma knife surgery
  • Transcranial magnetic stimulation
  • Regular check-ups with a healthcare team to manage symptoms

IMPORTANT FOR ALL PATIENTS.

If you are on any blood thinning medications such as anti-platelet, anti-coagulant or anti-inflammatory medications, they should be stopped one week prior to any surgery. Examples of these medications include plavix, co-plavix, prasugrel, ticagrelor, asasantin, aspirin, disprin, solprin, astrix, cartia, warfarin, pradaxa, dabigatran, rivaroxaban, apixaban, clexane, heparin, celebrex, mobic, naproxen, indomethacin, diclofenac, ibuprofen.

Some diabetes medications need to be stopped up to three weeks prior to surgery. Please discuss with your doctor if you are taking one of these medications.

Similarly, any herbal or natural remedies including (but not limited to) traditional Chinese herbal remedies and prescriptions, naturopathic and homeopathic treatments, and supplements (such as glucosamine, garlic, ginger, ginkgo, ginseng, turmeric and fish oil) should be stopped one week prior to any surgery.

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.
