This was tested in people. That is the most reliable kind of research we share.
This is a look back at past patients at one hospital, not a new treatment.
The short version
If stereotactic radiosurgery: Radiation aimed at a small target, in one visit or a few. There is no cutting, despite the name. See the glossary does not stop this tumor, surgery is still possible, but it is harder.
What was studied. Doctors at one hospital in India looked back at records from 2012 to 2023. Of 1633 people who had surgery for this nerve tumor, 24 had stereotactic radiosurgery: Radiation aimed at a small target, in one visit or a few. There is no cutting, despite the name. See the glossary first and later needed surgery.
What they found. The tumors got bigger. The average size went from 7.8 cc before stereotactic radiosurgery: Radiation aimed at a small target, in one visit or a few. There is no cutting, despite the name. See the glossary to 19.13 cc at the time of surgery. Surgery took about 332.92 minutes on average, with average blood loss of 570 mL. The tumor was stuck to the brainstem in 17 of the patients, and surgeons could find the facial nerve in 75.0% of cases.
What this means, and what it doesn't
What it could mean: Surgery is still an option if stereotactic radiosurgery: Radiation aimed at a small target, in one visit or a few. There is no cutting, despite the name. See the glossary does not control this tumor. The doctors said it is safe to do. But it is harder than surgery done first, so your surgeon may plan to take out as much as is safe instead of all of it. That choice helps protect the nerve that moves your face.
What it doesn't mean: This does not mean the second surgery is easy or risk free. The report says less of the tumor comes out, and the facial nerve is harmed more often. This was one hospital looking back at 24 past cases. It was not a trial, and it did not compare treatments head to head. It is not a cure, and it cannot tell you what will happen in your own case.
