  • Look Inside

No major technologic advance in neurosurgery has entered the mainstream faster than gamma knife (GK) ra-diosurgery. This neurosurgical procedure is based on the precise delivery of gamma ray irradiation to destroy a predetermined target volume without opening the skull. The field of GK radiosurgery, as a multidisciplinary ap-proach to different brain pathologies, continues to expand as technological aspects continue to improve. Applica-tions of GK radiosurgery are now woven within vascular neurosurgery, tumor neurosurgery, and, recently, func-tional neurosurgery. In management of patients with arteriovenous malformations, acoustic neurinomas and men-ingiomas, GK radiosurgery is now considered to be alternative to surgical intervention. Also, GK radiosurgery has recently played a major role in managing patients with brain metastasis, even though the lesion number exceeds 10~20 or more.

Furthermore, the role of GK radiosurgery in the field of functional surgery for pain, epilepsy, movement disor-ders and psychiatric disorders has evolved dramatically. In particular, for the treatment of trigeminal neuralgia, GK radiosurgery has been proven to be the least invasive procedure with a high incidence of pain relief as well as with a low rate of hypesthesia. In this chapter, avoiding to review redundant historical articles, the author de-scribes current issues in GK radiosurgery.
