Thyroglossal cyst develops from epithellial material of thyroglossal duct. Its remaining pieces can be appeared between foramen caecum linguae and isthmus glandulae thyroideae (they are in midline only).
Sometimes are transformed to aberant thyroid glands, with hormonal activities. Duct has to be separated from stripped and narrow m. thyreoglossus. This muscle connects thyroid gland surface and tongue root; it is a part of infrahyoid muscles. Cysts lie either in tongue root or in hyoid region. They can be opened to surface in foramen caecum (canal) as a thyroglossal fistula.
