This was tested in people. That is the most reliable kind of research we share.
This looked back at health records from people, and it is not a treatment.
The short version
Uneven hearing loss is common, but this ear nerve tumor is rare.
What was studied. Researchers used two large U.S. health databases. One held hearing tests from 14,293 adults. The other held 12,958 cases of a slow-growing, non-cancer tumor on the hearing and balance nerve.
What they found. The tumor was rare. About 1.4 to 1.8 people out of every 100,000 got one each year. Hearing loss that was worse in one ear was far more common. It rose with age, from 2.2% at ages 20-29 to 8.9% at ages 60-69. It was more common in men, 6.2%, than in women, 3.9%. Even in the best case, about 1,260 MRI scans would be needed to find one tumor. In younger adults, the number went up to about 54,200.
What this means, and what it doesn't
What it could mean: For people who already have symptoms, these hearing rules still work well. When a doctor sends someone for a scan, about 27 to 64 scans find one tumor. That is a much better use of scanning. This study says the rules make sense for people with symptoms, not for everyone.
What it doesn't mean: This does not mean hearing tests are useless. It does not mean you should skip a scan your doctor asks for. This was a study of health records, not a test of any treatment. It is not a new therapy, and it is not a promise of a cure. It changes nothing for a person who already has this tumor.
