It is common to see in the clinic that a baby has a nodule in the middle of the neck, about the size of a peanut rice, resembling an adult laryngeal node. This is a condition unique to the pediatric neck: a thyroglossal cyst. This cyst is an abnormal structure that remains in the neck when the baby gradually grows from the embryonic state to the human body size, and is named because of its close relationship with the hyoid bone. This cyst is characterized by being located superficially under the skin, but it also has a deep fistula that connects to the hyoid bone and extends through or over the hyoid bone to the pharynx. Therefore, surgery requires the removal of the cyst, a small section of the hyoid bone and any fistula that may be present in front of or behind the hyoid bone, and is essential to avoid postoperative recurrence. The removal of a small section of the hyoid bone has no effect on the baby’s ability to extend the tongue and pronounce sounds. If you bring your baby to our general surgery clinic, we will further clarify the diagnosis by local ultrasound examination and recommend early surgical removal after ruling out conditions such as ectopic thyroid gland that are not suitable for surgery. The lump will not subside naturally if it is observed for a long time; if secondary infection develops, it will instead cause local skin breakdown and the surgical incision will have to be enlarged accordingly.
