目的：Zuckerkandl肌（TZ）是甲状腺外侧突的残端，是甲状腺手术中喉返神经定位的重要解剖结构。此外，TZ的去除对于甲状腺全切除术的充分执行至关重要。然而，有很少提到的TZ在外科教科书或papers.Methods：前瞻性观察研究138个连续的甲状腺手术。TZ的存在，它的大小，以及与喉返神经的关系，被recorded.Results：共211个甲状腺叶被列入本研究。TZ在所有甲状腺叶中的识别率为61.1%。中位尺寸为8 mm（范围= 3 - 40 mm）。TZ在右侧（69.6%）比左侧（53.2%）更常见（P = 0.02）。98.4%的病例喉返神经位于TZ的深部。结论：TZ存在于大多数甲状腺叶。TZ的意识是进行充分的甲状腺全切除术的关键，是非常有用的作为一个标志的喉返神经。
Objective: 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.Methods: Prospective observational study of 138 consecutive thyroid surgeries. The presence of the TZ, its size, and relationship to the recurrent laryngeal nerve, were recorded.Results: 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.Conclusions: 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.
