- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Only three patients were watched during surgery, so this is still very early.
The short version
Doctors watched the hearing nerve during surgery, and all three patients could hear afterward with an implant.
What was studied. Doctors treated three people who had a tumor on a nerve near the ear. During surgery they used a tool called ANTS to check the hearing nerve the whole time.
What they found. The team was able to record the hearing nerve's signals through all three surgeries. After the tumor was taken out, each patient got a cochlear implant, which is a hearing device. All three patients could hear with the implant after surgery.
What this means, and what it doesn't
What it could mean: This tool may help a surgeon protect the hearing nerve while removing the tumor. If the nerve is protected, a hearing implant has a chance to work. Only a surgical team that has this tool can offer it.
What it doesn't mean: This does not prove the tool works. It was only three people, and there was no group to compare them to. Reports like this are early and can be wrong. The tool does not treat the tumor itself, and it is not a cure. Larger studies are needed before this becomes normal care.
