Gamma knife radiosurgery (GKRS) is currently regarded as one of the first-line treatment options for medically refractory TN. GKRS is a less invasive treatment with a low risk of complications than other surgical procedures that provides a favorable pain control (BNI I\u2013IIIb) rate of &gt;75% at short-term follow-up. Drawbacks of GKRS include the latency period before pain relief and higher recurrence rate compared with microvascular decompression. Therefore, repeat treatment is necessary if the initial GKRS was effective but followed by recurrence. The concept of dose rate and the biologically effective dose of radiation has been actively studied in radiation oncology and is also applied in GKRS for TN to achieve high safety and efficacy by prescribing the optimal dose. Recent progress in functional imaging, such as diffusion tensor imaging, enables us to understand the pathophysiology of TN and predict the clinical outcome after GKRS. Here, we review TN, GKRS, and recent updates, especially in the concepts of radiation dose, diffusion tensor imaging studies, and repeat treatment in GKRS for TN.<\/jats:p>","DOI":"10.3340\/jkns.2021.0303","type":"journal-article","created":{"date-parts":[[2022,7,1]],"date-time":"2022-07-01T06:17:46Z","timestamp":1656656266000},"page":"633-639","update-policy":"https:\/\/doi.org\/10.3340\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Gamma Knife Radiosurgery for Trigeminal Neuralgia : Review and Update"],"prefix":"10.3340","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1937-0074","authenticated-orcid":true,"given":"Seunghoon","family":"Lee","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8143-5513","authenticated-orcid":true,"given":"Jung-Il","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1892","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nurt.2007.05.011"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.3171\/sup.2005.102.s_supplement.0185"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.3171\/2010.7.gks101049"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrobp.2010.07.010"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2006.105.5.730"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1056\/nejm199604253341701"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007\/s10143-021-01474-9"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.clineuro.2013.12.003"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.3389\/fnins.2017.00554"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1159\/000075103"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1177\/1352458515579440"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1002\/nbm.4427"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.pain.2013.08.029"},{"key":"ref14","first-page":"351","volume-title":"Long-term outcomes of Gamma knife radiosurgery for classic trigeminal neuralgia: implications of treatment and critical review of the literature.
