To study the incidence of the tubercle of Zuckerkandl (ZT) among Indian patients subjected to thyroid surgery at a tertiary care cancer centre and its relevance in localization of recurrent laryngeal nerve (RLN). Prospective study on 144 patients (48 males, 96 females) undergoing thyroidectomy (35 hemithyroidectomies, 109 total thyroidectomies) from September 1st 2010 - February 28th 2013. 144 specimen/253 lobes (129 right, 124 left) were evaluated. Findings were recorded by the same team to ensure consistency. Presence, shape, grade (Pelizzo's) of ZT and relationship to RLN were documented. ZT was identified in 90.5 % (n = 229), commoner on the right (n = 120) than on left (n = 109). ZT was Grade 0 in 9.5 %, Grade I in 28.9 %, Grade II in 50.5 % and Grade III in 11 % of cases. In all patients ZT was unilobed. Recurrent laryngeal nerve (RLN) was consistent in position and was posterior to ZT in all cases. There were no branches of the RLN above the ZT. The ZT is a useful guide in locating RLN. Surgeon should be aware about the incidence, shape, grade and relation to RLN which is different in the Indian population as compared to what has been reported globally.
研究在一家三级癌症护理中心接受甲状腺手术的印度患者中祖克坎德尔结节（ZT）的发生率及其在喉返神经（RLN）定位中的相关性。对2010年9月1日至2013年2月28日期间接受甲状腺切除术（35例半甲状腺切除术，109例全甲状腺切除术）的144例患者（48例男性，96例女性）进行前瞻性研究。对144个标本/253个叶（129个右侧，124个左侧）进行评估。由同一团队记录结果以确保一致性。记录ZT的存在、形状、分级（佩利佐分级）以及与RLN的关系。在90.5%（n = 229）的病例中发现了ZT，右侧（n = 120）比左侧（n = 109）更常见。在9.5%的病例中ZT为0级，28.9%为I级，50.5%为II级，11%为III级。在所有患者中ZT均为单叶。喉返神经（RLN）位置恒定，在所有病例中均位于ZT后方。在ZT上方没有RLN的分支。ZT是定位RLN的有用向导。外科医生应了解其发生率、形状、分级以及与RLN的关系，印度人群中的情况与全球报道的有所不同。
