The objective of this technology review was to assess the efficacy of gamma knife SRS in the treatment of arteriovenous malformations, acoustic neuroma, cerebral metastases and trigeminal neuralgia, the latter representing a non-invasive approach to precision ablation for benign conditions. The efficacy of gamma knife relative to microsurgery and LINAC-based SRS was a particular focus of this review for all conditions excluding the treatment of trigeminal neuralgia.
