In simple words: This surgery removes a cyst or sinus (abnormal passage) connected to the thyroid gland.The cyst usually forms in the neck or under the chin. The surgeon removes the entire cyst and related tissue, including a small part of the hyoid bone (a small bone in the neck), to prevent the cyst from growing back.

This procedure involves the complete surgical removal of a thyroglossal duct cyst or sinus, encompassing its full extent from the base of the tongue to the neck, including resection of a portion of the hyoid bone.The procedure is indicated for recurrent cysts, often resulting from incomplete initial excision or inadequate infection control. The surgeon meticulously isolates the cyst and tract, ensuring complete removal to minimize recurrence. Hemostasis is achieved, and the wound is closed in layers.A drain may be placed post-operatively.

Example 1: A 10-year-old presents with a midline neck mass consistent with a thyroglossal duct cyst. The surgeon performs a Sistrunk procedure, removing the cyst, tract, and a portion of the hyoid bone. Pathology confirms the diagnosis., A 30-year-old has a recurrent thyroglossal duct cyst after a previous incomplete excision.The surgeon performs a more extensive Sistrunk procedure, requiring removal of additional tissue and a larger portion of the hyoid bone to achieve complete excision.A drain is placed postoperatively., A 5-year-old child presents with a thyroglossal duct sinus (an opening in the skin).The surgeon performs a Sistrunk procedure, removing the sinus tract, associated cyst, and a portion of the hyoid bone. The child has an uneventful recovery.

Preoperative imaging (e.g., ultrasound) to rule out other pathology and assess cyst extent.Detailed operative notes including extent of resection (cyst, tract, hyoid bone), and pathology report confirming complete excision.

** Recurrence rates vary depending on the completeness of the initial excision.The Sistrunk procedure, when performed correctly, significantly reduces the risk of recurrence.
