摘要
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。
Objective To study the relationship between Zuckerkandl＇ s tubercle （ZT）and the recmTent laryngeal nmwe （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 lohe only, ≤〈 6 mm ）, Grade 2 （ 6～10 ram） and Grade 3 （ larger than 10 ram）. ZT was classified into three groups according to its location in the thyroid. Results 88.2% （ 45/51 ） of the cada vers 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 toueh. There is close relationship be tween ZT and RLN.
