Colloid cysts in the thyroid gland are common clinical lesions of the thyroid gland. Depending on the size of the colloid cyst and the clinical symptoms, different treatment methods can be used. First, the volume is less than 3 cm thyroid colloid cyst, and the patient has no obvious pain, tracheal and esophageal compression symptoms. Considering that colloid cysts are benign lesions, patients are advised to review thyroid ultrasound and do not need to undergo surgery for the time being. Second, if the patient is under close observation, it is found that the size of the colloid cyst of thyroid gland is increasing too fast, and the symptoms of tracheal and esophageal compression appear, causing breathing or swallowing difficulties for the patient. In this case, even if it is a benign lesion, the thyroid cyst has a serious impact on the human body and surgery is recommended to remove the symptoms of compression of the surrounding organs.
