ABSTRACT

Thyroglossal duct cysts (TDCs) are common congenital neck masses resulting from persisting of the thyroglossal duct that enlarges because of inflammation, infection, and mucus retention. They can be found anywhere in the midline between the foramen cecum and the thyroid gland. TDCs are most frequently found below the level of the hyoid bone and may rarely occur above the hyoid. We reported and discussed the case of a 3- year -old child who suffered a mass at the base of tongue and was operated with Sistrunk procedure. After the surgery respiratory failure developed that required tracheal intubation and mechanical ventilation.
