Thyroglossal Duct Cyst


The thyroglossal duct forms during development of your child's thyroid before he or she is born. In some children, the thyroglossal duct does not disappear before birth. A cyst can form anywhere on the duct and become infected again until it is removed.


Call your local emergency number (911 in the US) if:

  • Your child is having trouble breathing.

Call your child's doctor if:

  • Your child's symptoms of infection return.
  • You have questions or concerns about your child's condition or care.


  • Antibiotics are used to treat a bacterial infection. Make sure your child takes all of the antibiotics, even if he or she starts to feel better.
  • Give your child's medicine as directed. Contact your child's healthcare provider if you think the medicine is not working as expected. Tell him or her if your child is allergic to any medicine. Keep a current list of the medicines, vitamins, and herbs your child takes. Include the amounts, and when, how, and why they are taken. Bring the list or the medicines in their containers to follow-up visits. Carry your child's medicine list with you in case of an emergency.

Follow up with your child's doctor as directed:

Your child's doctor may send your child to a specialist after the infection is gone. The specialist will create a plan to remove the thyroglossal duct and cyst. Write down any questions so you remember to ask them during your child's visit.
