目的 观察Zuckerkandl结节(zuckerkandl tubercle, ZT)与喉返神经（recurrent laryngeal nerve, RLN）的位置关系。方法 通过51例（102侧）非颈部疾病死亡尸体解剖观察ZT的形态、大小及其与喉返神经的位置关系。根据ZT的大小将其分为4度，0度：肉眼不易识别；1度：仅是甲状腺侧叶增厚形成≤6 mm；2度：6 ~10 mm；3度：>10 mm。 根据ZT在甲状腺上的位置将其分为3组：ZT位于甲状腺上1/3、中1/3、下1/3。结果 51例（102侧）尸体解剖中发现在右侧为88.2%（45/51），左侧为74.5%（38/51），两侧同时出现的为72.5%（37/51）。0度为12.7%（13/102），1度为3.9%（4/102），2度为54.9%（56/102），3度为28.4%（29/102）。ZT主要位于甲状腺侧叶中1/3部，有的越过喉返神经的主干或分支，有的指向喉返神经的主干或分支。结论 ZT作为一个新提出的解剖学标志位置较恒定，易于观察或触摸，方便实用，与喉返神经有密切关系。
Abstract
Objective To study the relationship between Zuckerkandl’s tubercle (ZT)and the recurrent laryngeal nerve(RLN). Methods We examined 51 specimens(102 sides) from cadavers , observed the shape,size and association with RLN.ZT was graded as Grade 0(unrecognizable), Grade 1(thickening of the lateral lobe only,≤6 mm), Grade 2(6~10 mm) and Grade 3(larger than 10 mm).ZT was classified into three groups according to its location in the thyroid. Results 88.2%（45/51）of the cadavers were found in the right side, 74.5%（38/51 in the left side and 72.5%（37/51）bilateral. 12.7%（13/102) were found to be of Grade 0, 3.9%（4/102) Grade 1, 54.9%（56/102）Grade 2 and 28.4%（29/102) of Grade 3. ZT was mainly located in the middle third of the thyroid gland. Some of the tubercles passed over the RLN or branches; some pointed to the RLN or branches. Conclusion As a new anatomical landmark ,ZT remains in a constant position and is easy to observe and touch.There is close relationship between ZT and RLN.
