The surgical steps of thyroglossal cyst excision include anesthesia, incision, separation of the cyst, treatment of the hyoid bone, cutting off the cyst, and suturing. 1. Anesthesia: the patient lies flat on the shoulder pads, head tilted back, general anesthesia is always used for children, adults can use local anesthesia, such as preoperative infections, there may be adhesions, general anesthesia will be used. 2. Incision: make a transverse incision parallel to the hyoid bone in the most elevated part of the cyst, with both ends slightly exceeding the range of the cyst. 3. Separate the cyst: pull the muscle flap upward and downward to expose the cyst. 4. Handle the hyoid bone: separate the middle part of the hyoid body from the appendicularis muscle and the hyoid membrane, and then cut off the middle part of the hyoid body together with the periosteum. 5. Cut off the cyst: hold the middle of the hyoid body with pincers and pull it outward, and continue to separate the cyst in the direction of the lingual blind hole. When it reaches the blind hole of the tongue, press the blind hole of the tongue forward through the mouth, and ligate and cut off the cyst here when the white membrane is peeled off to indicate that it has reached the submucosa. 6. Suture: rinse the cavity with saline, stop bleeding thoroughly, and close the cavity in layers without leaving any empty space. The broken end of the hyoid bone does not need to be sutured. If the operative cavity and the pharyngeal cavity have been connected, or the operative cavity is contaminated, or the operative cavity is large, the hyoid bone can be placed under the negative pressure drainage tube. Patients with thyroglossal cysts should go to the hospital in time and receive standardized treatment under the guidance of doctors.
