Zuckerkandl结节：甲状腺手术中一个重要的解剖标志

Zuckerkandl＇s tubercle, an anatomical landmark in thyroid surgery

目的探讨甲状腺手术中Zuckerkandl结节（zT）与喉返神经（RLN）和上甲状旁腺（sP）的解剖关系及临床应用。方法对我院同一手术组连续施行的153例甲状腺全切术（甲状腺癌121例，甲状腺良性疾病32例）行回顾性分析，观察zT的有无及大小，及与RLN和sP的解剖位置。结果zT出现在多数病例：在右侧为88．2％（135／153），左侧为82．4％（126／153），两侧同时出现的为76．5％（117／153）。RLN主要位于zT与甲状腺腺体之间，其右侧为91．7％（99／108），左侧94．7％（90／95）。sP右侧94．4％（102／108）在zT的头侧10点和11点钟方向，其左侧92．6％（88／95）在zT的头侧1点和2点钟方向。结论ZT与RLN和SP之间有着重要的解剖关系。

Objective To study the anatomical relation between Zuckerkandl＇s tubercle （ZT） and recurrent laryngeal nerve （RLN） and the superior parathyroid （SP） glands. Methods 153 patients （ 121 thyroid cancer and 32 benign diseases） underwent total thyroidectomy from May 2008 to February 2009 were included in our study. We investigated the ZT s presence or absence, size and association with the RLN and SP. Results ZT was identified in most patients. Among them, 88.2% （135/153） were found on right, 82.4% （90/95） on left and 76.5% （102/108） were found to be bilateral. The RLN was mainly located between the ZT and the main body of the thyroid and 91.7 % on right （99/108） and 94.7 % on left （90/95）. 94.4% of SP were located on the top of ZT at 10 or 11 o＇clock position and 92.6% at about 1 or 2 o＇clock position. Conclusions There was an important anatomical relationship between ZT and RLN and SP.
