The nonrecurrent laryngeal nerve is vulnerable during thyroid surgery. Pre-operative recognition of this nerve allows surgeons to avoid injuring the nerve. This anomaly depends upon the aortic arch anomaly and, therefore, in some cases, surgeons are able to predict the presence of this nerve pre-operatively by chest X-ray or barium swallow. Two patients with nonrecurrent laryngeal nerve are reported, one of whom, a 48-year-old man, had an abnormal shadow of the aortic arch, which led to confirmation of a right aberrant subclavian artery. Barium swallow plays a decisive role in the diagnosis of nonrecurrent laryngeal nerve, and this test is mandatory in patients who complain of difficulty in swallowing.
喉返神经在甲状腺手术中易受损伤。术前识别该神经可使外科医生避免损伤神经。这种异常取决于主动脉弓异常，因此在某些情况下，外科医生能够通过胸部X光或吞钡检查在术前预测该神经的存在。报告了2例喉返神经异常患者，其中1例48岁男性，主动脉弓有异常阴影，证实有右锁骨下动脉异常。吞钡检查在喉返神经异常的诊断中起决定性作用，对于主诉吞咽困难的患者，这项检查是必不可少的。
