Ansa cervicalis is a nerve loop that is embedded in the anterior wall of carotid sheath of the neck. It is formed by descendent hypoglossi and descendens cervicalis. It supplies the infrahyoid muscles. During routine dissection, a rare variant in the morphology of Ansa cervicalis was observed in adult male cadaver. The variant ansa cervicalis exhibited two loops, and was present bilaterally. The formation, course and relations of the nerve loop is complex. During literature search, we came across studies which propose different classifications. Hence we have added a note on the different classifications.Ansa cervicalis is important since it can be used in nerve-nerve anastomosis, nerve-muscle pedicle implantation in relation to reconstructive surgeries of larynx. Hence, the knowledge of variations in the formation, and distribution is relevant. It can affect the outcome during reinnervation surgeries following recurrent laryngeal paralysis and surgeries around this area of neck.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
