The non-recurrent course of the inferior laryngeal nerve is a rare ano
maly. The incidence varies from 0.3 to 4% on the right side. It is ext
remely rare on the left side. The awareness of such an anomaly is esse
ntial as the risk of damage to the nerve is higher during thyroid surg
ery. Two cases of non-recurrent laryngeal nerve are reported, and the
embryology and method of identification are discussed.
