Introduction. Non-recurrence and variations in ascending courseof the recurrent laryngeal nerve (RLN) represent a risk factor for nerveinjuries during thyroid surgery. Non-recurrent laryngeal nerve(NRLN) coexisting to recurrent nerve branch is a rare anatomyc anomaly.It could be a cause of nerve injuries during thyroidectomy. A systematicintraoperative nerve identification may allow an effectivenessprevention of iatrogenic injuries.Case report. We report one case of a young woman underwent tototal thyroidectomy (TT) for papillary thyroid carcinoma (PTC) wherewe found a rare variation of the right inferior laryngeal nerve anatomy.We identified both right laryngeal nerve structures before completingthyroidectomy avoiding possible nerve damage. The postoperativecourse was without complications.Discussion. Iatrogenic injury of RLN is one of the most seriouscomplication in thyroid surgery. Several risk factors favouring this complicationwere found as the presence of anatomic variations of the inferiorlaryngeal nerve. Identification of a normal caliber recurrent nervecan allow the surgeon to complete the thyroid excision; diversely, in caseof a smaller caliber nerve in the usual recurrent course, a careful dissectionshould be continued to demonstrate a possible merger with ipsilateralnon-recurrent nerve.Conclusions. The aim of this paper is to report a rare case of NRLNassociated to a smaller caliber branch of RNL. We emphasize that carefuldissection and intimate knowledge of normal and anomal anatomyallow for avoidance of nerve injury during surgery in the neck.
