BOCCALATTE, Luis A et al. Type-1 non-recurrent inferior laryngeal nerve. Rev. argent. cir. [online]. 2019, vol.111, n.1, pp.33-35. ISSN 2250-639X.

The non-recurrent laryngeal nerve (NRLN) is a variant of the recurrent laryngeal nerve (RLN) with an incidence between 0.25 and 0.99% according to the different series reported. The NRLN is consequence of a vascular anomaly during the embryological development of the epiaortic trunk. We report the case of a woman with type-1 NRLN as an intraoperative finding during total thyroidectomy. The NRLN is a rare anatomic variant that should be suspected when the right inferior RLN cannot be identified in the usual anatomic location after a standardized exploration.
