For cystic nodules in the right lobe of the thyroid gland, if the lesion is small, local aspiration with local puncture and injection of sclerosing agent into the capsule can allow gradual adhesion of the capsule wall to eliminate the nodule. If the nodules gradually increase in size and compress the adjacent trachea, and there is a significant sensation of gas pressure, surgical excision can be chosen, and local or general anesthesia can be chosen for the surgical operation. In the case of multiple cystic nodules, partial removal of the thyroid gland is also required. In addition, the thyroid function should be monitored after surgery, because some patients are prone to secondary hypothyroidism, which is manifested as anterior tibial mucinous edema, so attention should also be paid to thyroxine supplementation, and thyroid ultrasound should be reviewed regularly after surgery.
