With over 500,000 patients in over 249 select facilities worldwide benefiting from Gamma Knife radiosurgery, Wallace-Kettering Neuroscience Institute (WKNI) is proud to offer Southwest Ohio patients this breakthrough procedure so close to home. There are many life advantages that Gamma Knife radiosurgery may provide and your Neuroscience Team will discuss personal treatment results with you in depth. The following are reported treatment results listed by their specific condition.

  • Metastatic Tumors: Gamma Knife radiosurgery achieves control rates of 80-85 percent, essentially comparable to an open surgery without the risk of infection, bleeding or complications and without a lengthy hospital stay and convalescence.

  • Benign Tumors: Follow-up of ten years demonstrates control rates in more than 90 percent of cases. Fifty-three percent of tumors decrease in size while 40 percent remain stable in size. In some cases, combined treatment with surgery and Gamma Knife offers the best opportunity for tumor control.

  • Acoustic neuromas (Vestibular Schwannomas): Up to 98 percent of tumors either decrease in size or remain stable, with near complete facial nerve preservation, at six-year follow-up.

  • Pituitary Adenomas: Effective Control in a Majority of Patients; particularly beneficial for residual or recurrent tumors following surgery.

  • Vascular Malformations Such as Arteriovenous Malformations (AVMs): Complete obliteration of AVMs takes place in 60 to 70 percent of patients within two to three years of treatment.

  • Trigeminal Neuralgia: Initial pain relief in more than 80 percent of patients; long-term pain relief without medications in 63 percent of patients at four-year follow-up.
