The patients were categorized according to the treatment received into the endoscopic group (\n                      <jats:italic>n<\/jats:italic>\n                      =\u202f53) (endoscopic MVD) and the microscopic group (\n                      <jats:italic>n<\/jats:italic>\n                      \u202f=\u202f78) (microscopic MVD). All patients were treated under neuroelectrophysiological monitoring. The surgical time, identification of offending vessels, full exposure of trigeminal nerve (TN) structure, the rate of one-time decompression, postoperative efficacy, complications, postoperative hospital stay and recurrence rate were compared between both groups.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      There were differences in incision length and bone flap diameter between the two groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05). Endoscopy was more minimally invasive compared to microscopy; however, there was no significant difference in total surgical time and blood loss between the two groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;gt;\u202f0.05). In the group with no neurovascular compression identified during preoperative assessment, the surgical duration was significantly shorter with endoscopy compared to microscopy (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05), which indicated that endoscopic treatment has a time advantage in this condition. The consistency rate of preoperative magnetic resonance angiography (MRA) result and intraoperative offending vessels differed between the two groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05), indicating that endoscopy may be more accurate than microscopy in detecting offending vessels. Compared to microscopes, endoscopes provide a higher rate of full exposure of the TN (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05). This difference is primarily observed in cases where there is obstruction by the petrosal protuberance tubercle (PPT) or petrosal vein (PV). Additionally, endoscopes offer a higher rate of one-time decompression which means that the need to adjust the Teflon pledget is less frequent (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05), thereby reducing the number of nerve disturbances. There was no significant difference in postoperative remission rate and Barrow Neurological Institute Pain Intensity Score (BNI score) between the groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;gt;\u202f0.05). Compared to the microscopy group, the recurrence rate at 2\u202fyears and the last follow-up after endoscopic surgery was lower; however, the difference was not significant (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;gt;\u202f0.05). There was no significant difference in the incidence of postoperative complications, mortality rate, and length of hospital stay between the groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;gt;\u202f0.05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Endoscopic and microscopic MVD are effective for PTN and have comparable outcomes. Endoscopy enhances visualization and identification of offending vessels; moreover, compared with microscopy, endoscopy is more minimally invasive and suitable for detecting and fully separating potentially hidden offending vessels; however, its technical complexity necessitates individualized treatment based on patient needs and institutional expertise.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fneur.2025.1583192","type":"journal-article","created":{"date-parts":[[2025,7,2]],"date-time":"2025-07-02T00:14:31Z","timestamp":1751415271000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Comparison of endoscopic and microscopic microvascular decompression for treating primary trigeminal neuralgia"],"prefix":"10.3389","volume":"16","author":[{"given":"Lei","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongqi","family":"Shao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xialin","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuanbo","family":"Pan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huadong","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongjie","family":"Zhai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaohui","family":"Dong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengtian","family":"Fang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feiyun","family":"Lou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiquan","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,7,2]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"39","DOI":"10.1038\/s41572-024-00523-z","article-title":"Trigeminal neuralgia","volume":"10","author":"Ashina","year":"2024","journal-title":"Nat Rev Dis Prim"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"3437","DOI":"10.2147\/JPR.S331036","article-title":"Trigeminal neuralgia: current approaches and emerging interventions","volume":"14","author":"Xu","year":"2021","journal-title":"J Pain Res"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"289","DOI":"10.2147\/TCRM.S37592","article-title":"Advances in diagnosis and treatment of trigeminal neuralgia","volume":"11","author":"Montano","year":"2015","journal-title":"Ther Clin Risk Manag"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"1090478","DOI":"10.3389\/fneur.2022.1090478","article-title":"Case report: Fully endoscopic microvascular decompression for trigeminal neuralgia","volume":"13","author":"Jiang","year":"2022","journal-title":"Front Neurol"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"227","DOI":"10.17245\/jdapm.2024.24.4.227","article-title":"Factors associated with outcomes following microvascular decompression for the treatment of primary trigeminal neuralgia in adults: a systematic review and meta-analysis","volume":"24","author":"Silva","year":"2024","journal-title":"J Dent Anesth Pain Med"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"287","DOI":"10.1055\/a-2065-9650","article-title":"Pain outcomes following endoscopic microvascular decompression for trigeminal neuralgia based on vascular compression type","volume":"85","author":"Blue","year":"2024","journal-title":"J Neurol Surg B Skull Base"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"639","DOI":"10.3171\/2018.10.JNS181983","article-title":"A history of the Jannetta procedure","volume":"132","author":"Kaufmann","year":"2020","journal-title":"J Neurosurg"},{"key":"ref8","doi-asserted-by":"publisher","first-page":"32","DOI":"10.1055\/s-2002-23586","article-title":"Fully endoscopic vascular decompression of the trigeminal nerve","volume":"45","author":"Jarrahy","year":"2002","journal-title":"Minim Invasive Neurosurg"},{"key":"ref9","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1007\/s701-002-8269-4","article-title":"Anatomical observations during microvascular decompression for idiopathic trigeminal neuralgia (with correlations between topography of pain and site of the neurovascular conflict).
