This looks across many earlier studies rather than running a new one.
This looks back at past studies, and it does not show clearly that the checks help.
The short version
Doctors looked at past studies to see if watching brain signals during meningioma surgery helps, and the answer is still not clear.
What was studied. Researchers reviewed nine earlier studies with 576 surgery cases. All of them looked at meningiomas in the upper part of the brain. The studies tested checks of nerve and brain signals during surgery.
What they found. The ways doctors checked signals were very different from study to study. Some people had new problems after surgery whether or not their signals were checked, from 5.2 to 66% of patients. Some had problems even when their signals looked fine during surgery. The checks did help surgeons make choices in some cases, mostly when the tumor was near the part of the brain that controls movement.
What this means, and what it doesn't
What it could mean: Checking signals during surgery may help your surgeon find the brain areas that control movement. This could help guide choices during your operation. If you have a meningioma near these areas, you can ask your surgeon if they plan to use this kind of check.
What it doesn't mean: This does not prove that checking signals during surgery lowers the chance of problems afterward. It is a review of older studies, not a new test. The studies were small and very different from each other. Good signals during surgery do not promise there will be no problems after. This is not a cure for meningioma.
