Percutaneous Stereotactic Radiofrequency Rhizotomy (PSR)

Percutaneous Stereotactic Radiofrequency Rhizotomy (PSR)

If you’re experiencing the pain of trigeminal neuralgia, a chronic condition caused by the compression of a nerve in the face, your doctor will first recommend medication as a treatment. If this is not successful, your doctor may recommend a treatment called percutaneous stereotactic rhizotomy (PSR).

“Percutaneous” is a word that means your surgeon will use a needle to access the nerve. The surgeon will also use stereotactic radiofrequency, which is like an X-ray or an MRI, to get a picture of exactly where your nerve is located so it can be reached with the needle. A rhizotomy is the medical term that means a nerve is being destroyed to relieve your symptoms.

This is a minimally invasive outpatient procedure performed to relieve pain. PSR destroys the part of the nerve that is causing pain and also suppresses pain signals to your brain.
