Radiologic findings in persistent thyroglossal tract fistulas

Recurrent cysts and persistent fistulas are frequent complications of thyroglossal cystectomy if the excision is not extended through the hyoid bone to the foramen cecum. In 3 cases of persistent thyroglossal tracts, fistulography was performed and found to be valuable in demonstrating the extent of the tract. Surgical excision was completed and specimens were examined histologically. The retained upper portion of the thyroglossal tract was the established cause of the recurrent symptoms; removal of the entire tract up to the foramen cecum was confirmed as the recommended procedure.
