Nodules found in both lobes of the thyroid gland should also be combined with the patient’s clinical symptoms, as there are many people who can find nodules in the thyroid gland during a health checkup. For lesions less than 1 cm, the patient usually has no clinical symptoms and can be observed with regular follow-up. If the lesion is between 1-4 cm, radiofrequency ablation therapy is chosen to allow the nodules to gradually shrink. In addition, multiple nodules in the thyroid gland can be treated surgically if they are secondary to hyperthyroidism, or if they are not due to malignancy, and if they increase significantly in size in a short period of time, accompanied by weight loss, which is not due to hyperthyroidism. Isolated lesions that compress the trachea and cause a significant sensation of air pressure, affecting the patient’s daily life and work, are also indications for surgery.
