The main postoperative complications of thyroglossal cysts are infection and recurrent infection, which is the repeated failure of the wound to heal and to heal sterilely in one phase. Recurrent infection is stimulated by constant dressing changes and topical changes to stimulate the growth of fresh granulation and allow it to grow back into a fresh wound. Recurrence is when the thyroglossal cyst fistula, or the lingual canal is not completely cut, it is easy to recur and needs to be operated again to cut it out completely in order to prevent future recurrence. In order to prevent future recurrence, it is necessary to operate again to remove it completely. Because the infected stage is more invasive, another postoperative healing is not easy, and there will be more invasion of the surrounding tissue.
