Neurovascular compression of the VIII cranial nerve has been proposed as a potential etiology, and microvascular decompression (MVD) may represent a therapeutic alternative.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n We present a case series of seven patients with disabling tinnitus, vertigo, and, in some cases, hypoacusis, all of whom were refractory to at least 12 months of pharmacological treatment. Preoperative assessment included audiometry and high-resolution magnetic resonance imaging (fast imaging employing steady-state acquisition sequence), which confirmed a vascular loop contacting the VIII cranial nerve. Patients underwent retrosigmoid MVD, with follow-up ranging from 1 to 10 months.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n Five patients (72%) achieved complete resolution of tinnitus and vertigo, while two patients (28%) reported >80% improvement. One patient developed transient House\u2013Brackmann III facial palsy that resolved with steroids. No cases of permanent hearing loss, cerebrospinal fluid leak, or vascular complications were observed. Quality of life scores improved significantly postoperatively. The most common offending vessel was the anterior inferior cerebellar artery.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n MVD of the VIII cranial nerve is a safe and effective therapeutic option in selected patients with refractory tinnitus and vertigo, achieving substantial symptomatic improvement with a low complication rate. Larger prospective studies are warranted to validate these findings and establish long-term outcomes.<\/jats:p>\n <\/jats:sec>","DOI":"10.25259\/sni_982_2025","type":"journal-article","created":{"date-parts":[[2026,1,9]],"date-time":"2026-01-09T15:12:59Z","timestamp":1767971579000},"page":"17","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Microvascular decompression of the VIII cranial nerve for the treatment of refractory tinnitus and paroxysmal vertigo \u2013 A case series"],"prefix":"10.25259","volume":"17","author":[{"given":"Jos\u00e9 Luis","family":"Navarro-Olvera","sequence":"first","affiliation":[{"name":"Service of Stereotactic and Functional Neurosurgery, General Hospital of Mexico \u201cDr Eduardo Liceaga\u201d, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diana Paola","family":"Duarte Mora","sequence":"additional","affiliation":[{"name":"Service of Stereotactic and Functional Neurosurgery, General Hospital of Mexico \u201cDr Eduardo Liceaga\u201d, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jes\u00fas Quetzalc\u00f3atl","family":"Beltr\u00e1n Mendoza","sequence":"additional","affiliation":[{"name":"Service of Stereotactic and Functional Neurosurgery, General Hospital of Mexico \u201cDr Eduardo Liceaga\u201d, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose Dami\u00e1n","family":"Carrillo-Ruiz","sequence":"additional","affiliation":[{"name":"Service of Stereotactic and Functional Neurosurgery, General Hospital of Mexico \u201cDr Eduardo Liceaga\u201d, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"No\u00e9","family":"P\u00e9rez-Carrillo","sequence":"additional","affiliation":[{"name":"Service of Stereotactic and Functional Neurosurgery, General Hospital of Mexico \u201cDr Eduardo Liceaga\u201d, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gustavo","family":"Aguado Carrillo","sequence":"additional","affiliation":[{"name":"Neuroscience Coordination, Faculty of Psychology, An\u00e1huac University Mexico, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2026,1,9]]},"reference":[{"key":"10.25259\/SNI_982_2025\/ref-1","doi-asserted-by":"crossref","first-page":"1107","DOI":"10.1017\/S002221510013590X","article-title":"Meni\u00e8re\u2019s disease: Evolution of a definition","volume":"110","author":"Beasley","year":"1996","journal-title":"J Laryngol Otol"},{"key":"10.25259\/SNI_982_2025\/ref-2","doi-asserted-by":"crossref","first-page":"882","DOI":"10.1097\/00129492-200111000-00029","article-title":"Microvascular decompression of the vestibulocochlear nerve for disabling positional vertigo: The house ear clinic experience","volume":"22","author":"Brackmann","year":"2001","journal-title":"Otol Neurotol"},{"key":"10.25259\/SNI_982_2025\/ref-3","doi-asserted-by":"crossref","first-page":"2707","DOI":"10.3390\/biomedicines11102707","article-title":"Minimally invasive retrosigmoidal parasterional burr-hole approach: Technique and neuropathic pain amelioration after microvascular decompression of the trigeminal nerve","volume":"11","author":"Carrillo-Ruiz","year":"2023","journal-title":"Biomedicines"},{"key":"10.25259\/SNI_982_2025\/ref-4","doi-asserted-by":"crossref","first-page":"181","DOI":"10.1016\/S0194-5998(95)70102-8","article-title":"Committee on hearing and equilibrium guidelines for the diagnosis and evaluation of therapy in meniere\u2019s disease.
