Microvascular decompression (MVD) is the sole surgical technique directly addressing the underlying neurovascular conflict, offering durable pain relief. However, data from Latin American populations remain limited.<\/jats:p>\n                  <jats:p>To evaluate pain improvement, recurrence, and complications in patients with classic TN undergoing MVD at a Mexican high-specialty center.<\/jats:p>\n                  <jats:p>We retrospectively analyzed 61 consecutive classic TN patients who underwent MVD (2010\u20132023). Their clinical records provided demographic data, pain characteristics, Barrow Neurological Institute Pain Scale (BNI-PS) scores, intraoperative findings, and long-term outcomes. The statistical analyses were performed through the McNemar and Cochran Q tests for longitudinal changes.<\/jats:p>\n                  <jats:p>The cohort was predominantly composed of women (80.3%; median age: 59 years). Preoperatively, most reported severe pain (BNI-PS score: IV\u2013V). After MVD, 57.4% achieved complete pain relief (BNI-PS score: I) and 13.1% had occasional pain not requiring medication (BNI-PS score: II) at the long-term follow-up. Neurovascular compression was identified in 96.7% of the cases, most frequently by the superior cerebellar artery (49.2%). The overall recurrence rate was of 14.8%, with 8.2% requiring reoperation. Early complications included transient cerebellar syndrome (8.2%) and facial hypoesthesia (11.5%); 1 case of mortality occurred due to hypertensive hemorrhage.<\/jats:p>\n                  <jats:p>Microvascular decompression is a safe, effective, and durable treatment for classic TN, achieving long-term pain relief in more than 70% of the patients. The present study offers valuable clinical data from a Mexican cohort, reinforcing the efficacy and reproducibility of the procedure in diverse neurosurgical settings.<\/jats:p>","DOI":"10.1055\/s-0046-1817053","type":"journal-article","created":{"date-parts":[[2026,2,27]],"date-time":"2026-02-27T23:30:41Z","timestamp":1772235041000},"page":"001-008","source":"Crossref","is-referenced-by-count":1,"title":["Outcomes
