Computed Tomography Fistulography in the Diagnosis of Thyroglossal Fistula: A Case Report

Thyroglossal cysts, when ruptured due to infection or surgical intervention, often result in discharging sinuses or thyroglossal fistulas. While spontaneous rupture is common, the formation of a true fistulous tract connecting the base of the tongue to the neckand skin surface is less frequent. To prevent recurrences, complete excision of the tract and its branches is essential. Computed tomography (CT) fistulography emerges as the preferred diagnostic modality for visualizing thyroglossal fistulas and their branching patterns, thereby facilitating meticulous surgical planning. By employing this advanced imaging technique, surgeons can ensure the successful removal of the entire tract, minimizing the risk of future complications.
