non‑recurrent laryngeal nerve (nrln) is a rare anomaly which is reported in 0.3%‑0.8% of people on the right side and in 0.004% (extremely rare) on the left side. damage to this nerve during the surgical procedure may lead to severe iatrogenic morbidity and should therefore be prevented from being damaged. the best way to avoid this damage to the nerve is to identify the nerve with a systematic...

BACKGROUND It has recently been reported that a signal latency shorter than 3.5 ms after electrical stimulation of the vagus nerve signify a nonrecurrent course of the inferior laryngeal nerve. We present a patient with an ascending nonrecurrent inferior laryngeal nerve. In this patient, the stimulation latency was longer than 3.5 ms. CASE PRESENTATION A 74-years old female underwent redo sur...

OBJECTIVES To assess the possibilities of reinnervation in a paralyzed hemidiaphragm via an anastomosis between phrenic nerve and inferior laryngeal nerve in rabbits. Reinnervation of a paralyzed diaphragm could be an alternative to treat patients with ventilatory insufficiency due to upper cervical spine injuries. MATERIAL AND METHOD Rabbits were divided into five groups of seven rabbits eac...

A nonrecurrent laryngeal nerve variant of the inferior laryngeal nerve is very rarely seen, and surgeons should keep it in mind during thyroid surgery. Preoperative findings, like situs invertus and dysphagia lusoria, may be suggestive of a nonrecurrent laryngeal nerve. However, these findings always have not to be together with nonrecurrent laryngeal nerve, like our case.

We report two cases of a non-recurrent right inferior laryngeal nerve; per operative discovery during thyroidectomy. Through these cases, we highlight the clinical and surgical implications by fi...

Injury to the recurrent laryngeal nerve is a serious complication in thyroid and parathyroid surgery. The anatomy of the recurrent laryngeal nerve is variable. Non-recurrent nerve is a very rare variation of the inferior laryngeal nerve. Because of the anatomical variations of the nerve, preservation of the nerve is the optimal strategy during surgery. In this case report, we present a non-recu...

OBJECTIVES/HYPOTHESIS Right nonrecurrent inferior laryngeal nerve (NRLN) is an anatomical variant reported with a variable prevalence (0.3%-6%). It is associated with some arterial abnormalities (absence of the brachiocephalic trunk and presence of a right aberrant subclavian lusorian artery) that may be identified by preoperative ultrasonography (pUS). NRLN represents a major morbidity risk fa...

INTRODUCTION A non-recurrent course is a rare anatomic variation of the inferior laryngeal nerve (ILN). Bilateral extra-laryngeal bifurcation of the ILN seldom occurs before its laryngeal entry. Anastomosis between the ILN and cervical sympathetic chain is another rare anatomic feature. The prevalence of extra-laryngeal branching of the non-recurrent nerve is unknown. We present an example of t...
