To identify Zuckerkandl tubercle and to determine relationship between the recurrent laryngeal nerve and Zuckerkandl tubercle (ZT). Peroperative study. Intraoperatively Zuckerkandl tubercle was identified. Size of the thyroid lobe and Zuckerkandl tubercle were co-related and direction of tubercle in relation to recurrent laryngeal nerve was examined. Grading of tubercle on the basis of size was done. We studied its direction and relation with recurrent laryngeal nerve. ZT was identified in 87.86% (179 out of 206) of cases. In the study amongst the 179 cases in whom ZT could be identified, ZT was found on the right side (85.41% i.e. 123 out of 144), 81.41% (92 out of 113) to the left side and 15.68% (8 out of 51) were B/L. ZT was found posterior to the tubercle in 97.22%(175 out of 179) cases and anterior to the tubercle in 2.77% (5 out of 179) cases. The relationship between recurrent laryngeal nerve and ITA was studied. ITA was anterior to RLN (in 70.89%) and posterior to RLN in 29.10%. Thus, ZT is an important landmark for identification of RLN during thyroidectomy ( value 0.001). Level of evidence III.
识别祖克坎德尔结节并确定喉返神经与祖克坎德尔结节（ZT）之间的关系。手术中研究。术中识别祖克坎德尔结节。将甲状腺叶大小与祖克坎德尔结节进行相关性分析，并检查结节相对于喉返神经的方向。根据大小对结节进行分级。我们研究了其方向及其与喉返神经的关系。在87.86%（206例中的179例）的病例中识别出ZT。在该研究中，在可识别出ZT的179例病例中，右侧发现ZT的比例为85.41%（即144例中的123例），左侧为81.41%（113例中的92例），双侧为15.68%（51例中的8例）。在97.22%（179例中的175例）的病例中，ZT位于结节后方，2.77%（179例中的5例）的病例中，ZT位于结节前方。研究了喉返神经与甲状腺下动脉（ITA）之间的关系。ITA位于喉返神经前方的比例为70.89%，位于喉返神经后方的比例为29.10%。因此，在甲状腺切除术中，ZT是识别喉返神经的重要标志（P值0.001）。证据级别为III级。
