Abstract

Ling XY described 3 variations of RLN in relation to Inferior thyroid artery (ITA), with the RLN either being anterior to ITA, in between the branches of ITA or posterior to ITA. We add to these variations and present a new anatomical variation and course of RLN in which it lies in a lateral position and descends from a superior position on the thyrohyoid muscle to enter the larynx medially.
