Zuckerkandl's tubercle (thyroid gland)

Zuckerkandl's Tubercle is a small, pyramidal extension of the thyroid gland, which is often used as a landmark in thyroid surgery. It was first described by the Austrian anatomist Emil Zuckerkandl in 1902.

Anatomy

Zuckerkandl's Tubercle is located at the posterior aspect of the lateral lobes of the thyroid gland. It is present in approximately 80% of individuals and can vary in size from 1 to 10 mm. The tubercle is more commonly found on the right side of the thyroid gland and is often larger on this side.

Clinical Significance

The tubercle is of clinical significance as it is often used as a landmark in thyroid surgery. It is located close to the recurrent laryngeal nerve and the parathyroid glands, structures that are at risk of injury during thyroid surgery. Identification of Zuckerkandl's Tubercle can therefore help to protect these structures.

History

The tubercle was first described by the Austrian anatomist Emil Zuckerkandl in 1902. Zuckerkandl made significant contributions to the field of anatomy, particularly in relation to the endocrine system.
