Neural Monitoring

Paresis of the recurrent laryngeal nerve (RLN) is one of the serious complications of thyroid and parathyroid gland surgery. The intraoperative neural monitoring (IONM) enables to verify the functionality of RLN. The aim of this study is to compare the incidence of postoperative RLN palsy in patients who underwent surgery with and without the use of IONM RLN and to evaluate the positive and negative predictive values, sensitivity, specifi city and accuracy of the method. Methods: Retrospective analysis of thyroid gland surgeries performed within the period from 1. 7. 2016 to 1. 7. 2018. A total of 467 operations were performed (780 nerves exposed). One hundred and thirty procedures (215 nerves) were carried out without IONM (group A). In total, 337 procedures (565 nerves) were performed with IONM (group B). Results: In group A, unilateral postoperative RLN paresis occurred in 7 cases (3.26%); 6 of them were temporary (2.79%) and 1 was permanent (0.47%). In group B, unilateral postoperative RLN paresis occurred in 33 cases (5.84%); 32 of them were temporary (5.66%) and 1 was permanent (0.18%). The incidence of postoperative RLN paresis related to the use of IONM was not considered statistically signifi cant. (Chi-square test: P = 0.146; Fisher‘s exact test: P = 0.2015, P = 0.4715). The sensitivity, specifi city, positive predictive value, negative predictive value and accuracy were 78.79%, 99.25%, 86.67%, 98.69%, and 98.05%, respectively. There was no case of bilateral postoperative RLN paresis. Conclusion: There was no statistically significant diff erence in the incidence of postoperative RLN palsy in patients who underwent surgery with IONM compared to the group without IONM. The high negative predictive value, specifi city and accuracy indicate high reliability of the method. The IONM provides the surgeon with valuable information regarding the functional status of the nerve. This knowledge allows for changing the operative strategy during the procedure.

Background: This was a report of a movement of the recurrent laryngeal nerve which can be demonstrated during thyroid surgeries which can be used for locating the nerve, or identifying it if already exposed and causing confusion with other nearby structures or when alone too.Methods: The nerve is located by observing for a superior-inferior movement of the recurrent laryngeal nerve transmitted by the loose areolar tissue over it and dissecting over this site to locate the nerve right underneath it. This was by direct observation of the movement which will be there so long as the thyroid is held retracted to the opposite side and is not separated from the thyroid at the tissues that constitute the condensation of pre-tracheal fascia called the Berry’s ligament.Results: The recurrent laryngeal nerve originates from the vagus and loops posteriorly and then upwards around the arch of aorta on the left side and the subclavian artery on the right side. When the thyroid gland is retracted away and thus the nerve put on slight stretch, a superior-inferior to and fro- movement of the nerve can be seen. This movement can be used for identification and dissection of the nerve along its course.Conclusions: A review of literature has been done and it is clear that this movement has not been hitherto identified or published

AbstractObjective:To highlight a poorly known anatomical variation of the lateral lobe of the thyroid gland, which can be useful in identifying the recurrent laryngeal nerve during thyroid surgery.Materials and methods:We performed a three-year prospective study of 79 thyroid surgery patients. Great attention was paid to anatomical variations of the thyroid gland (i.e. the presence or absence of a distinct tubercle of Zuckerkandl), the recurrent laryngeal nerve and the location of the parathyroid glands.Results:A total of 71 right lobectomies and 74 left lobectomies were performed. Five tubercles of Zuckerkandl were identified (7.04 per cent of cases) and were useful in detecting the recurrent laryngeal nerve (but only on the right side).Conclusion:The tubercle of Zuckerkandl is a poorly known and variable anatomical feature of the thyroid gland which may not, in fact, be so rare. It arises for embryological reasons, and it can be a reliable anatomical landmark for identifying the recurrent laryngeal nerve during thyroid surgery. It should be included in the Nomina Anatomica as the ‘processus posterior glandulae thyroideae’ described by Zuckerkandl.
