Combined stepladder incision and Sistrunk procedure for en bloc resection of supraclavicular thyroglossal duct cysts

Abstract

Abstract The accurate diagnosis and therapeutic strategies of thyroglossal duct cysts (TGDCs) are challenging for surgeons if the opening with exudate is far from the hyoid bone. A 7-year-old boy presented with a right supraclavicular mass and persistent pus. Ultrasonography and magnetic resonance imaging revealed the fistula to the hyoid bone. Suspecting a TGDC, we combined the stepladder incision technique and the Sistrunk procedure. The first skin incision cut through the opening in a spindle shape, and the second incision was made in the skin just above the hyoid bone. This combined technique allowed en bloc resection of the TGDC and the hyoid bone to the base of the tongue. Cervical masses are commonly encountered in surgical clinics, and even distant openings off the midline must be considered in the differential diagnosis of TGDCs. This treatment strategy is essential for preventing the recurrence of TGDCs and ensures optimal cosmetic outcomes.
