Clinically, according to the different volume and size of the patient’s thyroid cyst, the specific nature of the cyst and whether the patient has obvious clinical symptoms, different treatment methods can often be taken: a. If the volume of the patient’s thyroid cyst is relatively small, the cyst does not compress the local neurovascular or important organs. The boundaries of the cysts are clear and uniformly echogenic through ultrasound examination, and there are no obvious signs of malignancy. Patients can be advised to review the thyroid ultrasound regularly to closely observe the changes of the cysts, and no special treatment is needed for the time being. Secondly, if the thyroid cyst is larger in size and compresses the laryngeal nerve, trachea and esophagus, the patient has different degrees of hoarseness and difficulty in breathing, and the cyst is found to have a longitudinal to transverse ratio greater than 1 and obvious blood flow signal and other malignant tumor signs through ultrasound examination. At this time, the condition of multiple cysts was more serious, and the patient was suggested to have surgery in time.
