[Thyroglossal duct remnants detected by ultrasonography after total thyroidectomy for thyroid carcinoma].

There are numerous reports of incidental findings of thyroglossal duct remnants (TGDR) after total thyroidectomy, but its implication on the outcome of patients with differentiated thyroid cancer (DTC) is unknown. The aim of this study was to determine the frequency of TGDR detected by ultrasonography after total thyroidectomy in patients with DTC and to evaluate the impact of this finding on the response to treatment. A total of 377 records of patients with DTC who received total thyroidectomy between January 1994 and January 2017 were reviewed.
