CyberKnife® Radiosurgery:
Treatment Effectiveness
There has been so much experience with Radiosurgery from acoustic neuroma, the chance of experiencing side effects is very low. The chance of experiencing temporary numbness or weakness of one side of the face is 2-3%. Preservation of useful hearing is generally achieved in 50-75% of the time. There are no risks of bleeding or infection, and almost no recovery period.
Radiosurgery is effective approximately 90% of the time in treatment of acoustic neuromas. Most tumors will stabilize in size, and then will shrink slowly. Shrinkage occurs in approximately 1/3 of tumors within a year after treatment. After 4 years, 2/3 of tumors are smaller, and within 10 years, more than 90% have diminished in size.
In the rare cases that radiosurgery does not result in control of the tumor (which is defined as either stabilization or shrinkage of the mass), it can generally be repeated, or the patient may undergo surgery at that time.
