Whether a thyroid cyst should be aspirated or surgically removed depends on the nature of the cyst. Thin-walled cysts and benign cysts of small size can be treated with aspiration, while malignant cysts and hemorrhagic cysts are usually treated with surgical removal. 1. Fluid extraction treatment: if it is a thin-walled cyst or a common cyst with small area, it can be directly treated by puncture and fluid extraction, and the injection of sclerosing agent can ensure the occurrence of aseptic necrosis of the cyst wall, so as to achieve the purpose of treating the cyst. Compared with the surgical excision method, the incision of fluid extraction treatment is smaller, and the damage to normal thyroid tissues is less. 2. Surgical excision: If there is no obvious demarcation between the substantial mass of thick-walled cyst and the surrounding tissues, as well as cysts whose contents are bloody and accumulate rapidly after repeated aspiration, we should be alert to the possibility of cancer, and it is best to use surgical treatment. Whether the thyroid cysts are pumped or directly cut, it is recommended that patients go to the hospital to do systematic examination and be judged by professional doctors to choose the most suitable treatment plan for patients.
