Current and novel practice of stereotactic radiosurgery

Stereotactic radiosurgery emerged as a neurosurgical discipline in order to utilize energy for the manipulation of brain or nerve tissue, with the goal of minimal access and safe and effective care of a spectrum of neurosurgical disorders. Perhaps no other branch of neurosurgery has been so disruptive across the entire discipline of brain tumor care, treatment of vascular disorders, and management of functional problems. Radiosurgery is mainstream, supported by thousands of peer-reviewed outcomes reports. This article reviews current practice with a focus on challenges, emerging trends, and areas of investigation.
