Abstract Objective: To highlight a poorly known anatomical variation of the lateral lobe of the thyroid gland, which can be useful in identifying the recurrent laryngeal nerve during thyroid surgery. Materials and methods: We performed a three-year prospective study of 79 thyroid surgery patients. Great attention was paid to anatomical variations of the thyroid gland (i.e. the presence or absence of a distinct tubercle of Zuckerkandl), the recurrent laryngeal nerve and the location of the… 
Zuckerkandl Tubercle of the Thyroid: A Common Imaging Finding That May Mimic Pathology
TLDR
Recognition of this feature of the thyroid gland at CT imaging can obviate the need for biopsy and avoid potential recurrent laryngeal nerve injury.
Importance of Tubercle of Zuckerkandl in Thyroid Surgery
TLDR
Recurrent Laryngeal Nerve was identified with the help of inferior thyroid artery (ITA) and Zuckerkandl tubercle in 68% of cases for safety and RLN could be safeguarded with theHelp of of ZT in this series of cases along with ITA.
The Tubercle of Zuckerkandl is Associated with Increased Rates of Transient Postoperative Hypocalcemia and Recurrent Laryngeal Nerve Palsy After Total Thyroidectomy.
TLDR
The tubercle of Zuckerkandl, when present and of significant macroscopic size is associated with increased rates of transient postoperative hypocalcemia and recurrent laryngeal nerve palsy.
The Rare Coincidence: Nonrecurrent Laryngeal Nerve Pointed by a Zuckerkandl's Tubercle
TLDR
Based on anatomical and embryological variations, it is suggested identification and full exposure of ILN before attempting excision of adjacent structures, like the ZT which has surgical importance for completeness of thyroidectomy.
Two Cases of Enlarged Zuckerkandl's Tubercle of the Thyroid Displacing the Recurrent Laryngeal Nerve Laterally
TLDR
The knowledge of the anatomy of ZT and its relation with the RLN including all variations is mandatory for safe thyroid operations.
Zuckerkandl Tubercle of the Thyroid Gland: Correlations between Findings of Anatomic Dissections and CT Imaging
TLDR
Zuckerkandl tubercles that protrude toward the posteromedial and superior or inferior direction could cause confusion due to their separation when performing diagnoses with CT images.
Incidence of tubercle of Zuckerkandl of the thyroid and it’s surgical relation with recurrent laryngeal nerve and the superior parathyroid gland
TLDR
Zuckerkandl’s tubercle is a posterior extension of lateral lobes of the thyroid gland, maintains a constant relationship with the RLN and the superior parathyroid gland during thyroid surgery.
Incidence and Surgical Importance of Zuckerkandl's Tubercle of the Thyroid and Its Relations with Recurrent Laryngeal Nerve
TLDR
RLN is unusually laying lateral to ZT which is common structure in the thyroid, and may be more vulnerable to injury, and should be fully isolated before excision of adjacent structures.

Incidence and importance of the tubercle of Zuckerkandl in thyroid surgery.
TLDR
The TZ is a distinct feature of the thyroid gland that can be recognised during most thyroidectomies and has no constant relationship to preoperative symptoms.
Zuckerkandl's tubercle of the thyroid gland in association with pressure symptoms: a coincidence or consequence?
TLDR
Observations in the present study supported a strong association of enlarged ZT with pressure symptoms, and it is believed that in a relatively small-size goitre the ZT may cause significant pressure symptoms.
The inferior laryngeal nerve: surgical and anatomic considerations. Report of 251 thyroidectomies
TLDR
The inferior laryngeal nerve is characterized by its important anatomic variations, especially on the right side, and these variations might be different even between males and females.
Superior approach to the inferior laryngeal nerve in thyroid surgery: anatomy, surgical technique and indications
TLDR
The anatomical bases of the surgical access to the higher part of the thyroid lobe, with first location and complete dissection of the inferior laryngeal nerve are described to discuss the advantages and disadvantages of this surgical technique and to determine the operational indications.

TLDR
In a study of 500 recurrent laryngeal nerves, the inferior cornu of the thyroid cartilage was more reliable than the inferior thyroid artery in identifying the recurrent lickengeal nerve.
A safe technique for thyroidectomy with complete nerve dissection and parathyroid preservation.
TLDR
A series of 1,000 consecutive thyroid operations is presented, without a case of permanent recurrent laryngeal nerve injury, due in part to the avoidance of ligating the inferior thyroid artery in continuity and the technique of extracapsular dissection of the thyroid gland.
