The thyroglossal duct is an
thyroid gland and its final position. It is located exactly mid-line, between the anterior 2/3 and posterior 1/3 of the tongue
.
The thyroid gland starts developing in the
oropharynx in the fetus and descends to its final position taking a path through the tongue, hyoid bone and neck muscles. The connection between its original position and its final position is the thyroglossal duct. This duct normally atrophies and closes off as the foramen cecum before birth
but can remain open in some people.
Clinical significance
A thyroglossal duct that fails to atrophy is called a
thyroglossal duct cyst.[1]
