thyroglossal cyst is a lump or mass in the neck that is filled with fluid. During pregnancy, the fetal thyroid gland begins to form at the base of the tongue and moves to the neck below the thyroid cartilage. The cyst forms when part of the thyroglossal duct does not disappear and remains after birth, resulting in the formation of a thyroglossal cyst.

Endotracheal anesthesia for thyroglossal cyst resection is a general anesthesia technique with endotracheal intubation for the purpose of controlling respiration during the surgery to remove the thyroglossal cyst and for postoperative resuscitation.

Thyroglossal cyst is the most common congenital malformation of the mid-neck region, related to the existence of the thyroglossal duct. During the formation of the thyroid gland, if the thyroglossal duct does not disappear and persists after birth, it will cause thyroglossal cyst.
