The presence of NRLN was intraoperatively confirmed in 28 patients. All the NRLNs were located on the right side and its overall incidence was 0.37%. Five of the NRLNs were classified as type I, 19 as type IIa, and 4 as type IIb. Of the 28 cases, 4\u00a0NRLNs were injured during surgery, in which primary end\u2010to\u2010end anastomosis or local seal with corticosteroid injection was performed as a remedy. In the 4 patients with NRLN injury, 2 presented with postoperative hoarseness that indicated vocal cord paralysis confirmed by laryngoscope; the other 2 patients\u2019 voices had no significant changes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The NRLN, which is rare in clinical practice and predominantly right\u2010sided, is anatomically more complex and variant at a higher risk of surgical injury. The key factors to accurately identify NRLN and to effectively prevent its injury include careful interpretation of auxiliary examination results before surgery, raising awareness of its presence, meticulous dissection, and routine exposure of the RLN during surgery.<\/jats:p><\/jats:sec>","DOI":"10.1177\/0194599817700583","type":"journal-article","created":{"date-parts":[[2017,4,18]],"date-time":"2017-04-18T08:20:19Z","timestamp":1492503619000},"page":"210-216","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Anatomic
