This was tested in people. That is the most reliable kind of research we share.
This was a small look back at past surgeries, not a planned trial.
The short version
Surgeons tried a different path into the spinal cord, and the few patients who had it did well.
What was studied. Doctors looked back at Fourteen patients who had surgery for a spinal cord tumor high in the neck. 9 had the standard cut down the middle of the cord, and 5 had a side route called the DREZ approach.
What they found. Surgery took less time with the side route, 261 minutes compared with 315 minutes. The whole tumor was removed in 80% of the side route cases and 33% of the midline cases. Nerve function stayed the same or got better after the side route, while trouble walking after surgery was more common with the midline cut.
What this means, and what it doesn't
What it could mean: For some tumors in the upper neck, this side route may be a safe choice. It may lower the risk of walking problems after surgery. If you face this operation, you can ask your surgeon which route fits your tumor.
What it doesn't mean: This does not mean one surgery is better than the other. The study was very small and only looked back at past records. The authors say no firm conclusion can be drawn, and larger planned studies are needed. It is not a cure, and it does not change standard care today.
