Zuckerkandl's tubercle: incidence and relationship with the inferior laryngeal nerve

Description
Summary:	The iatrogenal lesion of the inferior laryngeal nerve (ILN) during thyroid surgery is an incident, which can have greatest functional after-effects. Its research is recommended during cervicotomy for thyroidectomy and it can be easily found by the presence of Zuckerkandl tubercle, which is a postero-lateral excrescence of the thyroid gland. The main objective of our study was the researching of the presence of this Zuckerkandl tubercle and appreciating the reports with the ILN. From 1st October 2010 to 30th September 2012, we realized a continuous prospective study on a mono-operator series of 48 patients operated on for thyroidectomy. The Zuckerkandl tubercle has been researched from all the patients and classified according to the classification of Pelizzo et al. From 21 patients (43.75%), the Zuckerkandl tubercle has been well identified and it was grade 3 and grade 2. In those cases, the ILN was very closed to the tubercle. For the 27 other patients (56.25%), the tubercle was practically undetectable or reduced to a small glandular mound (grades 0 and 1). The connections with the nerve in this case were less evident. The zuckerkandl tubercle is comparatively frequent and is refound more than one time over 3 in our study. Its presence makes easier the identification of the ILN, which entertains a dangerous connection with the thyroid gland.
