Patient: 2007.11.onset 2007.12 surgical excision 2008.12 recurrence surgical excision and recurrence to hospital treatment Doctor: Hello! Is your child suffering from “thyroglossal cyst”? This is a developmental disease that occurs during the formation of the thyroid gland, and can occur anywhere from the tongue’s blind orifice to the thyroid pathway, and is especially closely related to the hyoid bone, so surgery must remove a section of the hyoid bone to prevent recurrence. Of course, there are some residual epithelium that is difficult to remove completely, and sometimes it is prone to recurrence after surgery. I wonder what specialty the surgery was performed in?
