Original title: Subperineural 'onion-peeling' dissection for maximizing extent of resection and facial nerve preservation for onco-functional balance in vestibular schwannoma surgery.

- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This is a look back at past patients of one surgeon, not a study that compared treatments.
The short version
One surgeon reports that a careful peeling method removed most of the tumor while keeping facial movement.
What was studied. Researchers looked back at 146 people who had a vestibular schwannoma removed by one surgeon. The surgeon used an 'onion peeling' method that leaves a thin layer of tissue over the facial nerve as a buffer.
What they found. At the last check, 95.2% of patients had good facial movement. The surgeon removed at least 95% of the tumor in 97.3% of patients. The tumor came back in 3.4% of patients, and 2.7% had a fluid leak after surgery. Patients were followed for 89.8 months on average.
What this means, and what it doesn't
What it could mean: For some people, surgery may be able to take out most of the tumor and still protect the face. It is worth asking your surgeon what method they use and what their own results are.
What it doesn't mean: This does not mean the method is proven better than other options. It is a look back at one surgeon's past patients, not a trial that compared two groups head to head. Results from one skilled surgeon may not match what happens elsewhere. It is not a cure, and it is not a promise about how your own surgery will go.
