Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: The Sistrunk operation is the standard procedure for removing a thyroglossal duct remnant. It involves excision of the cyst or fistula along with the central part of the hyoid bone and the tract up to the foramen cecum at the base of the tongue.
Step 2: Removing the body of the hyoid bone and the full tract is essential because the duct passes through or close to the hyoid; leaving it behind leads to recurrence.
Step 3: The procedure is used both for a thyroglossal cyst and for a thyroglossal fistula, which is simply a cyst that has discharged and formed a sinus. Therefore both option b and option c are correct, making the answer option d.
Step 4: A parotid tumour (option a) is treated by superficial or total parotidectomy, not by Sistrunk's operation, so it is incorrect.
