How often can hearing be preserved in acoustic neuromas?

Isaac Yang, MD
Neurosurgery
If a person has an acoustic neuroma, his hearing may be compromised.

A more recent study into radiosurgery as a treatment option found that if the treatment dose was 12.5 grey or less, hearing was more likely to be preserved. This means that people with acoustic neuromas will have a higher rate of hearing preservation if the radiation dose is lower than 12.5 Gy. The study also found that overall hearing preservation in people who had hearing preserved in advance was approximately 50-60% based on radiosurgery therapy. This was based on both linear accelerator radiosurgery as well as gamma knife radiosurgery.
