This was only done in mice, not in people.
The short version
In mice, turning off one inner ear enzyme helped stop hearing loss caused by radiation.
What was studied. Radiation, called stereotactic radiosurgery, is a standard treatment for a tumor called vestibular schwannoma. It often causes hearing loss that gets worse and does not come back. Researchers gave mice this kind of radiation. They then blocked an inner ear enzyme called NOX3 in two different ways.
What they found. Mice bred without NOX3 kept their hearing. The tiny hair cells and nerve cells in their inner ear stayed healthy. In a second test, the team used a small treatment to switch NOX3 off for a short time. Those mice had much less hearing loss and less inner ear damage than mice that did not get it. Blocking NOX3 also lowered signs of damage and swelling in the inner ear.
What this means, and what it doesn't
What it could mean: This points to one possible way to protect hearing during radiation. Doctors know ahead of time when radiation will happen. So a hearing treatment could be timed to go with it. For now this is an early lead for scientists, not something a patient can ask for.
What it doesn't mean: This work was done only in mice, not in people. It does not mean a hearing protection drug is ready or safe for humans. It does not treat the tumor itself, and it is not a cure. Many more steps and years of testing in people would be needed first.
