This was tested in people. That is the most reliable kind of research we share.
This was a look back at past patient records, not a test of a new treatment.
The short version
People with tumors at the lower back of the brain had the most trouble eating by mouth after surgery.
What was studied. Doctors looked back at hospital records of 68 people with tumors that started in the brain, all treated with surgery at one hospital in Brazil. They used a simple scale to rate how well each person could eat and drink by mouth before and after the operation.
What they found. The 68 people had tumors in many parts of the brain. More of them were women, and the most common tumor type was meningioma. The biggest change in eating by mouth after surgery was in people with tumors in the posterior fossa: The space low at the back of the skull. It holds the cerebellum, which helps with balance, and the brain stem. See the glossary, the lower back part of the brain. Two people needed another way to take in food right after surgery. Both worked with speech therapists and were eating better by mouth when they left the hospital.
What this means, and what it doesn't
What it could mean: If your tumor is in the lower back part of the brain, your care team may watch your eating and swallowing closely after surgery. Help from a speech therapist may be part of your recovery. Asking about this before surgery is fair and reasonable.
What it doesn't mean: This does not mean a new treatment or a cure. It was a look back at old records from one hospital, not a trial of anything. A study like this can show a pattern, but it cannot prove what causes eating trouble. It does not tell you what will happen in your own case.
