Section 1

A thyroglossal cyst is congenital remnant from the descent of the thyroid into the front of the neck and is therefore attached to the tongue via the embryological tract.

  • Dermoid cyst
  • Thyroid goitre
  • Ranula
  • Laryngocele
  • Epidermoid cyst
  • Branchial cleft cyst – usually away from midline
  • Ultrasound neck

  • Thyroid function tests

  • MRI 

  • CT scan

  • Radioactive iodine scan

  • This may inform you whether there is normal thyroid tissue present or whether the thyroglossal cysts is the only functional thyroid tissue, if so removal may result in hypothyroidism.

  • If acutely infected, antibiotics and aspiration may be required. Incision and drainage should be avoided if possible to avoid fistulation and recurrence following surgery. 

  • Surgical excision via Sistrunk’s procedure.
