The Tubercle of Zuckerkandl (TZ), which is the remant of the lateral thyroid process, is an important anatomic structure that serves as a reliable landmark for the recurrent laryngeal nerve in thyroid surgery. Furthermore, removal of the TZ is critical for the adequate performance of a total thyroidectomy. However, there is little mention of the TZ in surgical textbooks or papers.
Prospective observational study of 138 consecutive thyroid surgeries. The presence of the TZ, its size, and relationship to the recurrent laryngeal nerve, were recorded.
A total of 211 thyroid lobes were included in the study. The TZ was identified in 61.1% of all thyroid lobes. The median size was 8 mm (range = 3-40 mm). A TZ was more commonly identified on the right (69.6%) than on the left side (53.2%) (P = .02). The recurrent laryngeal nerve was found deep to the TZ in 98.4% of cases.
A TZ is present in the majority of thyroid lobes. Awareness of the TZ is critical in performing an adequate total thyroidectomy, and is very useful as a landmark for the recurrent laryngeal nerve.
甲状旁腺结节（TZ）是甲状腺侧叶的遗迹，是甲状腺手术中喉返神经的可靠标志，也是行全甲状腺切除术的关键。然而，TZ 在外科手术教材或论文中很少提及。
对 138 例连续甲状腺手术进行前瞻性观察研究。记录 TZ 的存在、大小及其与喉返神经的关系。
共有 211 个甲状腺叶纳入研究。在所有甲状腺叶中，61.1% 发现了 TZ。其大小中位数为 8 毫米（范围=3-40 毫米）。右侧（69.6%）比左侧（53.2%）更常见（P =.02）。98.4% 的情况下，喉返神经位于 TZ 的深部。
TZ 存在于大多数甲状腺叶中。了解 TZ 对于行充分的全甲状腺切除术至关重要，而且作为喉返神经的标志非常有用。
