thyroglossal fistula resection

In the early stage of the embryo, the thyroid primordial root descends from the tongue with a pedicled tubular structure along the midline, that is, the thyroid tongue tube, and the residual of the tube becomes the cause of the thyroglossal fistula. The thyroglossal fistula must be surgically removed, and it is generally appropriate for surgery over 1 year old. If the abscess is formed, the drainage is first cut, and the operation is performed after the infection is controlled to form the fistula. Treatment of diseases: thyroglossal cysts and fistulas Indication The thyroglossal fistula must be surgically removed, and it is generally appropriate for surgery over 1 year old. If the abscess is formed, the drainage is first cut, and the operation is performed after the infection is controlled to form the fistula. Surgical procedure Injecting a small amount of methylene blue liquid from the mouth of the mouth helps to identify the direction of the fistula. The incision is usually made by a transverse fusiform incision around the fistula. Excision of the scar near the skin and fascia, muscle tissue. The fistula is fragile and should be pulled lightly to avoid difficulties caused by the fracture. Routinely remove the central part of the hyoid bone with the fistula 0.5~1cm, and then separate the fistula from the blind hole. In order to understand the distance between the fistula and the oral cavity, the assistant can use the finger to extend into the entrance cavity, push the base of the tongue forward and downward, and put the fistula in the oral mucosa. The lower part is cut through the ligation. The incision was sutured layer by layer after suturing the genioglossus and mandibular ligament muscle. complication 1. Surgical wound infection In the case of infective fistula resection, care must be taken to avoid wound infection and hemostasis should be improved. 2. The recurrence of fistula is caused by incomplete resection of the diseased tissue. The operation must be performed strictly according to routine practice and cannot be simplified arbitrarily.
