A 46-year-old man developed head tremors at 41 and a right-sided neck tilt three years later. Five years after the onset of the head tremors, tightness of the larynx during speech and tremors in both the upper and lower limbs also appeared. The Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) score was 24, and the Fahn-Tolosa-Marin Tremor Rating Scale (FTM) score was 48. We captured the pallidothalamic tract and Vim along a single trajectory by locating the entry point in the inferior parietal lobule. One week after treatment, the TWSTRS and FTM scale scores were 9 (62.5%) and 30 (37.5%), respectively. No adverse events were observed.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>This case suggests that in dystonic tremors involving abnormalities of the basal ganglia-thalamo-cortical and cerebello-thalamo-cortical circuits, a single electrode can be used to approach both circuits through the parietal lobe approach.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_311_2023","type":"journal-article","created":{"date-parts":[[2023,11,3]],"date-time":"2023-11-03T05:45:57Z","timestamp":1698990357000},"page":"390","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Radiofrequency ablation of the pallidothalamic tract and ventral intermediate nucleus for dystonic tremor through the parietal approach"],"prefix":"10.25259","volume":"14","author":[{"given":"Shiro","family":"Horisawa","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kilsoo","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makiko","family":"Sakaguchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takakazu","family":"Kawamata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takaomi","family":"Taira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10894","published-online":{"date-parts":[[2023,11,3]]},"reference":[{"key":"10.25259\/SNI_311_2023\/ref-1","doi-asserted-by":"crossref","first-page":"67","DOI":"10.1007\/978-3-7091-1482-7_11","article-title":"Deep brain stimulation of the ventrolateral thalamic base and posterior subthalamic area in dystonic head tremor","volume":"117","author":"Buhmann","year":"2013","journal-title":"Acta Neurochir Suppl"},{"key":"10.25259\/SNI_311_2023\/ref-2","doi-asserted-by":"crossref","first-page":"773","DOI":"10.1007\/s00701-016-2725-4","article-title":"One-pass deep brain stimulation of dentato-rubro-thalamic tract and subthalamic nucleus for tremor-dominant or equivalent type Parkinson\u2019s disease","volume":"158","author":"Coenen","year":"2016","journal-title":"Acta Neurochir (Wien)"},{"key":"10.25259\/SNI_311_2023\/ref-3","doi-asserted-by":"crossref","first-page":"1644","DOI":"10.1093\/brain\/awz085","article-title":"Network-level connectivity is a critical feature distinguishing dystonic tremor and essential tremor","volume":"142","author":"DeSimone","year":"2019","journal-title":"Brain"},{"key":"10.25259\/SNI_311_2023\/ref-4","doi-asserted-by":"crossref","first-page":"135","DOI":"10.1159\/000103408","article-title":"Stereotactic treatment of different kinds of spasmodic torticollis","volume":"32","author":"Hassler","year":"1970","journal-title":"Confin Neurol"},{"key":"10.25259\/SNI_311_2023\/ref-5","first-page":"522","article-title":"Stereotaxic treatment for spasmodic torticollis","volume-title":"Stereotaxy of the human brain","author":"Hassler","year":"1982"},{"key":"10.25259\/SNI_311_2023\/ref-6","doi-asserted-by":"crossref","first-page":"216","DOI":"10.3171\/2019.9.JNS191202","article-title":"Unilateral pallidotomy in the treatment of cervical dystonia: A retrospective observational study","volume":"134","author":"Horisawa","year":"2019","journal-title":"J Neurosurg"},{"key":"10.25259\/SNI_311_2023\/ref-7","doi-asserted-by":"crossref","first-page":"857","DOI":"10.1002\/acn3.51333","article-title":"Safety and efficacy of unilateral and bilateral pallidotomy for primary dystonia","volume":"8","author":"Horisawa","year":"2021","journal-title":"Ann Clin Transl Neurol"},{"key":"10.25259\/SNI_311_2023\/ref-8","doi-asserted-by":"crossref","first-page":"478","DOI":"10.1002\/acn3.51532","article-title":"Unilateral pallidothalamic tractotomy at Forel\u2019s field H1 for cervical dystonia","volume":"9","author":"Horisawa","year":"2022","journal-title":"Ann Clin Transl Neurol"},{"key":"10.25259\/SNI_311_2023\/ref-9","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1159\/000076654","article-title":"Functional stereotactic surgery for treatment of cervical dystonia: Review of the experience from the lesional era","volume":"82","author":"Loher","year":"2004","journal-title":"Stereotact Funct Neurosurg"},{"key":"10.25259\/SNI_311_2023\/ref-10","doi-asserted-by":"crossref","first-page":"2217","DOI":"10.1007\/s00415-023-11569-6","article-title":"DBS in tremor with dystonia: VIM, GPi or both?
