Case Discussion

Once diagnosed all thyroglossal duct cysts should be excised since infection is common making surgery more difficult, cosmetically less satisfactory and higher risk of high recurrence.

Ultrasound examination to determine the precise location of the thyroid gland is recommended since in thyroid hypoplasia, a small central area of aberrant ectopic thyroid may be mistaken for thyroglossal duct cyst with the risk of excision and hypothyroidism.

The aim of surgery is to remove the entire duct including the central part of the hyoid bone in order to prevent recurrence.
