It is also anatomically related to the thyroid gland; although the thyroid isthmus is inferior to it, the two lobes of the thyroid extend superiorly on each side of the cricoid as far as the thyroid cartilage above it.
The posterior part of the cricoid is slightly broader than the anterior and lateral parts, and is called the lamina, while the anterior part is the band; this may be the reason for the common comparison made between the cricoid and a signet ring.
Gastric reflux could cause aspiration if this is not done considering the general anesthesia can cause relaxation of the gastro-esophageal sphincter allowing stomach contents to ascend through the esophagus into the trachea.
