Clinicopathological studies on thyroglossal duct remnant.

The clinicopathological findings in 48 cases underwent complete surgical excision of epithelial tissue of the thyoglossal duct remnants were reviewed. Simple incision of the cyst does not seem to have any therapeutic value and would be followed frequently by recurrence. The widely used Sistrunk procedure 2,6 surgical excision of the central portion of the hyoid bone together with fibrous tract extending to the base of tongue, seems to be warranted in some cases so long as complete eradication of the epithelial tissue can be made.
