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.

Nonrecurrent Laryngeal Nerve

ABSTRACT Purpose of the study Aimed to highlight a rare anatomical variation of right recurrent laryngeal nerve and a brief review of literature. Nonrecurrent laryngeal nerve is a rare anatomical variation with an incidence of 0.5 to 0.7% in thyroid surgery. It is difficult to identify this variation preoperatively either by imaging or by signs and symptoms, unless a vascular anomaly is suspected. This study aims to underline the necessity of recognizing the possibility of non-RLN and also to follow a systematic dissection of recurrent laryngeal nerve during thyroid surgeries, to prevent intraoperative nerve damage.

AbstractPurpose of the study:We aimed to highlight a rare anatomical variation involving the recurrent laryngeal nerve, and to emphasise its implications for thyroid surgery.Materials and methods:Over a period of 13 years, 993 patients underwent thyroid surgery; 1557 recurrent laryngeal nerves (887 on the right side) were exposed.Results:Three non-recurrent laryngeal nerves were found on the right side, associated with a retro-oesophageal subclavian artery. One case was suspected before surgery.Discussion:Several variations in the path and branches of the recurrent laryngeal nerve have been reported in the literature. The frequency of occurrence of a non-recurrent laryngeal nerve is about 1 per cent, for patients undergoing thyroid surgery. Other surgically relevant anatomical variations of the recurrent laryngeal nerve include associations with the inferior thyroid artery and the presence of nerve branches.Conclusion:The recurrent laryngeal nerve must be carefully dissected and totally exposed during thyroid surgery in order to best preserve its function. Moreover, the thyroid surgeon must be aware of the existence of anatomical variations, which are not as rare as one may think.

Laryngeal muscles paresis ranks second in prevalence of postoperative complications after thyroid surgery. Intraoperative neuromonitoring (IONM) of recurrent laryngeal nerve (RLN) results in reduction of cases with dysphonia and prevents such severe complication as bilateral paresis. Currently there are two types of monitoring: intermittent and continual. When using intermittent IONM surgeon has no opportunity to control electrophysiology state of RLN during intervals between stimulations. In case of continual IONM date on amplitude and latency are available to surgeon in real time every second, allowing him instantly react to any disturbance of neural transmission to prevent its damage by changing surgical manipulation. This work presents the first experience of using continual neuromonitoring of RLN in Russia, the procedure is described in details its safety. It is represented the possibility of prevention of bilateral laryngeal muscles paresis.
