Treatment options include a tracheostomy to bypass the site of obstruction as well as unilateral transverse cordotomy to alleviate the obstruction. The objective of this review is to determine the efficacy, adverse event profile, and long\u2010term outcomes, including the need for tracheostomy, in patients undergoing unilateral cordotomy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The Preferred Reporting Systems for Systematic Reviews and Meta\u2010Analysis (PRISMA) guidelines were followed for this systematic review. A literature search of unilateral cordotomy was performed by searching PubMed, Cochrane Library, and Embase. Articles presenting cases of BVFI treated with unilateral cordotomy were included. Review articles, animal studies, non\u2010English\u2010language articles, and abstracts were excluded. Articles presenting cases of bilateral cordotomy or cordotomy with arytenoidectomy were excluded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We identified 14 studies and 291 patients undergoing unilateral cordotomy. Sixty\u2010eight patients had a prior tracheostomy in place at the time of cordotomy. The most common post\u2010operative complication was granulation tissue formation (<jats:italic>n<\/jats:italic>\u00a0=\u00a039). Thirty\u2010one patients developed glottic edema with subsequent dyspnea. Three patients developed scarring of the primary cordotomy site with the return to an obstructed airway. Nine patients required a post\u2010cordotomy tracheostomy due to these complications. Five patients required a long\u2010term tracheostomy and were unable to be decannulated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Unilateral cordotomy is an effective treatment for glottic obstruction with high post\u2010operative decannulation rates. Adverse events including worsening glottic obstruction are uncommon, although edema and granulation tissue may develop in the post\u2010operative period and necessitate close post\u2010operative monitoring. <jats:italic>Laryngoscope<\/jats:italic>, 133:6\u201314, 2023<\/jats:p><\/jats:sec>","DOI":"10.1002\/lary.30097","type":"journal-article","created":{"date-parts":[[2022,3,7]],"date-time":"2022-03-07T13:11:37Z","timestamp":1646658697000},"page":"6-14","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Unilateral Cordotomy: A Systematic Review of Efficacy and Outcomes"],"prefix":"10.1002","volume":"133","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1785-1085","authenticated-orcid":false,"given":"Guy","family":"Talmor","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery Rutgers\u2010New Jersey Medical School  Newark New Jersey U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2168-7935","authenticated-orcid":false,"given":"Christopher","family":"Tseng","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery Rutgers\u2010New Jersey Medical School  Newark New Jersey U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brandon","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery Rutgers\u2010New Jersey Medical School  Newark New Jersey U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9572-6872","authenticated-orcid":false,"given":"Ido","family":"Badash","sequence":"additional","affiliation":[{"name":"Caruso Department of Otolaryngology\u2014Head and Neck Surgery University of Southern California  Los Angeles California U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0299-3697","authenticated-orcid":false,"given":"Corina Din","family":"Lovinescu","sequence":"additional","affiliation":[{"name":"New York Center for Voice and Swallowing Disorders Mount Sinai St. Luke's Roosevelt  New York New York U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian","family":"Benson","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery Hackensack University Medical Center  Hackensack New Jersey U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rachel","family":"Kaye","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery Rutgers\u2010New Jersey Medical School  Newark New Jersey U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,3,7]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"209","volume-title":"The Larynx.
