Treatment - Radiosurgery

Radiosurgery is a noninvasive medical procedure that utilizes targeted, large doses of radiation to treat tumors, lesions and other medical disorders.  Tumor shape and location are precisely identified and concentrated beams of radiation are delivered from multiple angles.  The surrounding healthy tissue remains undisturbed.  Radiosurgery is painless and provides a less risky alternative to conventional surgery for appropriate candidates.  Procedures may last from 30 minutes to several hours depending upon the instruments used and the complexity of the tumor.  Patients may be discharged within 24 hours after the procedure.  Gamma Knife Radiosurgery uses a lightweight metal frame attached to the head to focus the radiation.  Cyber Knife radiosurgery does not require a head frame, but rather uses a robotic arm to deliver the treatment.  Multicenter trials are currently under way to test the effectiveness of Radiosurgery as an alternative to standard temporal lobe resections in persons with Temporal Lobe Epilepsy.
