The physiological function of this rare brainstem reflex is yet to be fully established.<\/jats:p>\n <\/jats:sec>\n \n Patient Concerns:<\/jats:title>\n TCR occurs in a variety of surgeries, such as neurosurgical, maxillofacial, dental and skull base surgeries with bradycardia as the presenting sign.<\/jats:p>\n <\/jats:sec>\n \n Diagnosis:<\/jats:title>\n This is a clinical profile of two patients who presented with schwannoma of the trigeminal nerve.<\/jats:p>\n <\/jats:sec>\n \n Outcomes:<\/jats:title>\n Intraoperatively, during dissection of tumour, both patients had bradycardia with hypotension.<\/jats:p>\n <\/jats:sec>\n \n Treatment:<\/jats:title>\n The first patient had a spontaneous recovery but the other required intervention with vasopressors.<\/jats:p>\n <\/jats:sec>\n \n Take-Away Lessons:<\/jats:title>\n One must be aware of the rare occurrence of TCR mainly while operating on a rare occurring TS. Ceaseless intraoperative monitoring and being prepared with adequate measures while manipulating close to the nerve will prevent serious complications.<\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/ams.ams_141_20","type":"journal-article","created":{"date-parts":[[2023,1,10]],"date-time":"2023-01-10T13:33:58Z","timestamp":1673357638000},"page":"216-218","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Trigeminocardiac Reflex as a Complication of Excision of Schwannoma of the Trigeminal Nerve - A Rare Clinical Case Report"],"prefix":"10.4103","volume":"12","author":[{"given":"Ronald","family":"Anto","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeyashanth","family":"Riju","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konduru","family":"Vidya","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amit Jiwan","family":"Tirkey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-18-20240828","doi-asserted-by":"crossref","first-page":"373","DOI":"10.1007\/s12663-013-0541-4","article-title":"Trigeminocardiac reflex: A reappraisal with relevance to maxillofacial surgery","volume":"13","author":"Bhargava","year":"2014","journal-title":"J Maxillofac Oral Surg"},{"key":"R2-18-20240828","doi-asserted-by":"crossref","first-page":"e484","DOI":"10.1097\/MD.0000000000000484","article-title":"Trigeminal cardiac reflex: New thinking model about the definition based on a literature review","volume":"94","author":"Meuwly","year":"2015","journal-title":"Medicine (Baltimore"},{"key":"R4-18-20240828","doi-asserted-by":"crossref","first-page":"711","DOI":"10.3171\/jns.1995.82.5.0711","article-title":"Surgical treatment of trigeminal schwannomas","volume":"82","author":"Samii","year":"1995","journal-title":"J Neurosurg"},{"key":"R5-18-20240828","doi-asserted-by":"crossref","first-page":"22","DOI":"10.3389\/fneur.2017.00022","article-title":"Chronic Trigemino-cardiac reflex: An underestimated truth","volume":"8","author":"Chowdhury","year":"2017","journal-title":"Front Neurol"},{"key":"R6-18-20240828","doi-asserted-by":"crossref","first-page":"181","DOI":"10.1007\/s12663-016-0959-6","article-title":"Trigemino-cardiac reflex: A phenomenon neglected in maxillofacial surgery?","volume":"16","author":"Joshi","year":"2017","journal-title":"J Maxillofac Oral Surg"},{"key":"R8-18-20240828","doi-asserted-by":"crossref","first-page":"e9033","DOI":"10.1097\/MD.0000000000009033","article-title":"The clinical surrogate definition of the trigeminocardiac reflex: Development of an optimized model according to a PRISMA-compliant systematic review","volume":"96","author":"Meuwly","year":"2017","journal-title":"Medicine (Baltimore"},{"key":"R9-18-20240828","doi-asserted-by":"crossref","first-page":"1317","DOI":"10.1016\/j.joms.2009.12.039","article-title":"Classification of potential risk factors for trigeminocardiac reflex in craniomaxillofacial surgery","volume":"68","author":"L\u00fcbbers","year":"2010","journal-title":"J Oral Maxillofac Surg"},{"key":"R10-18-20240828","doi-asserted-by":"crossref","first-page":"375","DOI":"10.4103\/0028-3886.55577","article-title":"Management of the trigeminocardiac reflex: Facts and own experience","volume":"57","author":"Arasho","year":"2009","journal-title":"Neurol India"}],"container-title":["Annals of Maxillofacial Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/ams.ams_141_20","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T15:31:53Z","timestamp":1787758313000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/ams.ams_141_20"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,7]]},"references-count":8,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2022]]}},"URL":"https:\/\/doi.org\/10.4103\/ams.ams_141_20","relation":{},"ISSN":["2231-0746"],"issn-type":[{"value":"2231-0746","type":"print"}],"subject":[],"published":{"date-parts":[[2022,7]]}}}
