Non recurrent laryngeal nerve (NRLN) is an extremely rare entity constantly associated with an aberrant right subclavian artery also called arteria lusoria. Knowing this association can help predicting a NRLN preoperatively and thus to prevent its injury. We present two patients in whome this association was proven.

Background: According to the anatomical data, the non-recurrent laryngeal nerve is a rather common abnormality and can be found in 4.78% of people. At the same time, the non-recurrent laryngeal nerve is difficult to visualize during surgery, which increases the risk of its damage. Aim: to determine the possibilities of ultrasound of neck vessels in the preoperative diagnosis of the aberrant right subclavian artery (arteria lusoria) and the abnormality of the branches of the vagus nerve. Materials and methods: An observational, single-center, single-stage, randomized, uncontrolled clinical trial was performed, which included patients in whom surgery was performed due to thyroid and parathyroid pathology. In the preoperative period, all patients underwent the ultrasound of the right half of the neck vessels and the mediastinum with visualization of the brachiocephalic trunk and its branches. When the brachiocephalic trunk was detected in the preoperative period, mobilization of the thyroid gland during operation was started with ligation of the upper pole vessels, and followed by a search for the recurrent laryngeal nerve. However, if the brachiocephalic trunk was absent, the right common carotid artery was traced as low as possible to the aortic arch and assessed on its relationship with the right subclavian artery. In such cases, thyroid mobilization was started from the lateral surface of the lobe with the necessary visualization of all structures of this region and followed by a primary search for the inferior laryngeal nerve. When the non-recurrent laryngeal nerve was detected, the computed tomography of the brachiocephalic arteries was performed in the postoperative period. Results: The study has shown that 202 (95.28%) patients out of the total 212 revealed the brachiocephalic trunk on preoperative ultrasound and the recurrent laryngeal nerve was located in a the typical place. Arteria lusoria was detected in 4 (1.89%) cases after the preoperative ultrasound. In this group of patients the non-recurrent laryngeal nerve was identified during operation and the aberrant right subclavian artery was confirmed at computed tomography. In 6 (2.83%) cases the brachiocephalic trunk could not be detected on ultrasound due to the constitutional features of the patient. However, in all these cases, the typical recurrent laryngeal nerve was identified during a surgery. Conclusions: The ultrasound of the neck vessels is the effective method to detect arteria lusoria, which is the predictor of the non-recurrent laryngeal nerve.

Nonrecurrent Laryngeal Nerve

ABSTRACT A nonrecurrent laryngeal nerve is a rare anomaly and estimated to be present in 0.25 to 0.99% of patients.1 The identification and preservation of the recurrent laryngeal nerve is an essential part of thyroid surgery. It is now well-known that the recurrent laryngeal nerve is not only a single nerve but also a complex branching network of innervation. Thyroid surgery demands a precise understanding of the anatomical intimacy between the gland and surrounding structures, including the parathyroid glands and neurovascular tissue. The morbidity associated with thyroid surgery, in the short-term, generally relates to hematoma collection and hypocalcemia. Long-term morbidity is more commonly seen with dysphonia and vocal cord dysfunction due to superior laryngeal nerve damage and its role in explosive sound formation, the recurrent laryngeal nerve, its tortuous anatomical course, and its role in laryngeal musculature innervation. We review the literature on this subject and report three cases of the rare nonrecurrent anomaly, firstly a 75-year-old lady with a large retrosternal goiter. During her initial work-up which included a CT scan of the thorax, an ‘arteria lusoria' was identified in the retroesophageal plane. Intraoperatively, a right-sided nonrecurrent inferior laryngeal nerve (NRILN) was identified. The second case is of a 63-year-old lady with a right-sided type 1 nonrecurrent laryngeal nerve which we identified and photographed when medially retracting the gland off the central compartment and ligament of Berry. The third case is that of a 45-year-old lady with a right-sided thyroid nodule and a right-sided NRILN identified intraoperatively.

Short And Long Term

Objective: Approximately one out of five patients with Graves' disease (GD) undergoes a thyroidectomy after a mean period of 18 months of medical treatment. This retrospective and non-randomized study from a teaching hospital compares short- and long-term results of total (TT) and subtotal thyroidectomies (ST) for this disease. Methods: From 1987 to 1997, 94 patients were operated for GD. Thirty-three patients underwent a TT (mostly since 1993) and 61 a ST (keeping 4 to 8 grams of thyroid tissue - mean 6 g). All patients had received propylthiouracil and/or neo-mercazole and were in a euthyroid state at the time of surgery; they also took potassium iodide (lugol) for ten days before surgery. Results: There were no deaths. Transient hypocalcemia (< 3 months) occurred in 32 patients (15 TT and 17 ST) and persistent hypocalcemia in 8 having had TT. Two patients developed transient recurrent laryngeal nerve palsy after ST (< 3 months). After a median follow-up period of seven years (1-15) with five patients lost to follow-up, 41 patients having had a ST are in a hypothyroid state (73%), thirteen are euthyroid (23%), and two suffered recurrent hyperthyroidism, requiring completion of thyroidectomy. All 33 patients having had TT - with follow-ups averaging two years (0.5-8) - are receiving thyroxin substitution. Conclusions: There were no instances of persistent recurrent laryngeal nerve palsy in either group, but persistent hypoparathyroidism occurred more frequently after TT. Long after ST, hypothyroidism developed in nearly three of four cases, whereas euthyroidy was maintained in only one-fourth; recurrent hyperthyroidy was rare.
