Nonrecurrent Laryngeal Nerve: An Indian Documentation

Purpose of the study: Aimed to highlight a rare anatomical variation of right recurrent laryngeal nerve and a brief review of literature.Nonrecurrent laryngeal nerve is a rare anatomical variation with an incidence of 0.5 to 0.7% in thyroid surgery. It is difficult to identify this variation preoperatively either by imaging or by signs and symptoms, unless a vascular anomaly is suspected.This study aims to underline the necessity of recognizing the possibility of non-RLN and also to follow a systematic dissection of recurrent laryngeal nerve during thyroid surgeries, to prevent intraoperative nerve damage.
