Per Operative Study of Relation of Zuckerkandl Tubercle with Recurrent Laryngeal Nerve in Thyroid Surgery

Abstract

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 (p value 0.001).
