Gamma Knife radiosurgery can be used for solitary or multiple tumors. Whole brain radiation therapy is sometimes used in addition to Gamma Knife. Gamma Knife radiosurgery is highly effective even for tumors that are relatively resistant to traditional external beam radiation therapy. Treatment with Gamma Knife appears to improve longevity and also quality of life. Meningiomas Meningiomas are benign dural based tumors.
Associated morbidity is low with an excellent rate of stabilization of neuralgic status.
Difficult skull base tumors and recurrent or residual meningiomas are especially suited to Gamma Knife radiosurgery. Pituitary Tumors Pituitary tumors requiring surgical intervention are generally best managed by microsurgery. Gamma Knife radiosurgery is very useful in treating recurrent or residual tumors, especially in the cavernous sinus. Gamma Knife radiosurgery has an excellent track record in the treatment of Acoustic Neuromas. Even preservation of useful hearing has been seen in a high percentage of cases.
