Abstract: 【Abstract】 Objective To investigate Zuckerkandl tubercle and its anatomical relationship with the recurrent laryngeal nerve (RLN). Methods〓102 consecutive thyroid surgeries were included in the prospective study. The presence of the ZT, its size, and relationship to the RLN were recorded. Results〓A total of 124 thyroid lobes were included in the study. ZT was identified in 62.9% of all thyroid lobes. The median size was 9.5 mm (range 3-40 mm). There is no difference in the probability that ZT was identified on the right (68.2%, 45/66) or the left side (56.7%, 33/58, P>0.05). When ZT was present, the RLN was found deep to the ZT in 97.4% of cases. Conclusion〓In our study, ZT was present in the majority of thyroid lobes. And ZT may be a real constant landmark pointing to the RLN. In order to find and protect RLN during thyroid surgery, a careful, bloodless, and meticulous dissection should be carried out around the Zuckerkandl tubercle.
