The inferior thyroid artery crosses behind the lower part of the vessel.
2.
In such cases, it is known as the accessory inferior thyroid artery.
3.
The inferior thyroid artery runs superiorly from the thyrocervical trunk to the inferior portion of the thyroid gland.
4.
In this region, the recurrent laryngeal nerve and the inferior thyroid artery pass next to or in the ligament.
5.
The vascular supply to the laryngopharynx includes the superior thyroid artery, the lingual artery and the ascending pharyngeal artery.
6.
The injection of dye into the inferior thyroid artery can be used as an alternate method in identification the recurrent laryngeal nerve.
7.
The external branch is susceptible to damage during thyroidectomy or cricothyrotomy, as it lies immediately deep to the superior thyroid artery.
8.
The transversal thyroid lobe is reached and is rotated up to discover and ligate the thyroid vein to separate the thyroid artery.
9.
The artery may be present as an accessory thyroid artery but sometimes appears to compensate for incompetence or absence of one or more main thyroid vessels.
10.
The structure is important in thyroid surgery as it is closely related to the recurrent laryngeal nerve, the inferior thyroid artery, Berry's ligament and the parathyroid glands.
