Radioisotope Scanning of the Thyroid Gland Prior to Thyroglossal Duct Cyst Excision

The imperative of the Sistrunk operation: Review of 160 thyroglossal tract remnant operations

“…Scintigraphy is primarily used to demonstrate normal thyroid tissue, reducing the postoperative risk of hypothyroidism due to inadvertent removal of the only functioning thyroid tissue presenting in the TTRs. Most investigators agree that the rate of ectopic thyroid tissue is between 1 to 2 percent 5 . In our current study, only one case of lingual TTR was diagnosed in a 3-month-old boy who presented with stridor, cyanosis, dysphagia, and tachypnea.…”

“…Most investigators agree that the rate of ectopic thyroid tissue is between 1 to 2 percent. 5 In our current study, only one case of lingual TTR was diagnosed in a 3-month-old boy who presented with stridor, cyanosis, and tachypnea. Airway obstruction was the indication for surgery although ectopic thyroid tissue was suspected (the results were unclear) preoperatively by scintigraphy.…”

Thyroglossal duct cysts: clinicoradiological diagnosis and outcome of surgery

“…Radioisotope study, thyroid scintigraphy, is done to document the presence of the normal functioning thyroid gland. Preoperative sonographic identification of a normal thyroid gland in patients with TGDC confirms the origin of the thyroid hormone and excludes ectopic thyroid [22].…”

Midline Ectopic Thyroid Mimicking as a Thyroglossal Duct Cyst

“…It has been shown to be greater than 95% sensitive and specific for differentiating ectopic thyroid tissue from other midline neck masses. 9,10…”
