What to do if the thyroid nodule is benign cystic solid needs to be discussed in each case. If the nodule is benign and there are no obvious symptoms, it can be checked regularly. If the nodule is large and causing pressure, surgery is usually recommended under medical supervision. Thyroid nodules that cause pressure on the thyroid tissue and surrounding tissues may lead to breathing difficulties and food obstruction if not treated in time, so surgery is recommended: 1. Total thyroidectomy: This surgery requires the removal of the entire thyroid gland, which can achieve the purpose of completely removing the lesions. After the surgery, patients are prone to hypothyroidism, and need to take long-term levothyroxine sodium tablets for replacement therapy. 2. Thyroid lobectomy: the surgery is targeted removal of diseased tissue, less damage, faster recovery after surgery, for some early malignant lesions and most benign lesions. 3. Microwave ablation: it is mainly applicable to the reduction and elimination of benign nodules. If benign cystic solid thyroid nodules are found, it is recommended that endocrinology department should further consult the doctor for thyroid function, thyroid pathology biopsy and other examinations, so as to make a clear diagnosis and then formulate an individualized treatment plan.
