This was tested in people. That is the most reliable kind of research we share.
This was done in a single child, and it has not been compared with other methods.
The short version
Doctors describe a gentle method for taking out a hard to reach brain tumor through the nose.
What was studied. This is a report on a single surgery with a video. Doctors operated on a 4-year-old girl with a craniopharyngioma. That is a tumor near the base of the brain. They worked with a camera and small tools passed through her nose.
What they found. The tumor was wrapped in a thin covering that came from the pituitary stalk. The doctors cut just under that covering as they worked. They say this let them take the whole tumor out. They also say it kept them from touching nearby nerves and blood vessels. They report the method helps protect the brain parts that control hormones.
What this means, and what it doesn't
What it could mean: Surgery for this tumor has to balance two goals. Doctors want to remove all of it and still protect hormone glands. Methods like this one aim to do both. If this surgery is on the table, you can ask the surgeon how they plan to protect those glands.
What it doesn't mean: This is a surgeon describing a technique, not a study that compares methods. It does not prove this way is safer or better than other ways. It was not tested in a group of patients. It is not a new treatment you can ask for, and it is not a cure. Only your surgical team can say if this approach fits a specific tumor.
