Thyroid nodules are located on both sides of the laryngeal nodes in a round or oval shape, with smooth surface, clear borders, firm texture or cystic feeling, no adhesion to the skin, no pressure pain, and can move up and down with swallowing movements. It mostly occurs in young and strong women aged 20-40. The lumps are mostly single or multiple, with slow growth and no conscious symptoms. If this disease is not treated in time, there is a risk of deterioration at a later stage. There are many treatment options, so how can they be treated? Commonly used methods for treating thyroid nodules 1, traditional drug therapy: mainly used for a short period of time, nodules combined with hyperthyroidism, hypothyroidism, thyroiditis when the application of drug therapy. At present, the use of drugs is not recommended for the treatment of thyroid nodules. Drug treatment features: low cost, can quickly control the examination indicators and alleviate some clinical symptoms, but drug side effects, anti-thyroid drugs generally damage the liver and kidneys and reduce white blood cells, the duration of medication is generally 2-3 years, can not stop the medication, the relapse rate is about 30% to 50%, the majority of people taking anti-thyroid drugs can be tolerated, but it is true that a small number of patients can appear allergic, bone marrow suppression, liver damage. However, a small number of patients do experience allergy, bone marrow suppression, and liver damage, so patients with severe liver disease should not be treated with medication. Patients taking oral antithyroid drugs should have their blood and liver functions checked regularly at the hospital. Sometimes 131I is used to treat functional thyroid nodules, which can be very effective. 2.Surgical treatment: It is mainly used for hyperthyroidism, nodules and adenomas that have been affected for a long time and have no effect after long-term medication. Features: fast results. Disadvantages: High cost, many sequelae, leading to destruction of the thyroid gland, which will turn into irreversible hypothyroidism after surgery, and then need to take medication for life. High risk of surgery, which may damage the parathyroid glands and the recurrent laryngeal nerve and cause hoarseness after surgery. Hypocalcemia, etc. 3, thyroid RFA radiofrequency ablation “reasonable choice of technology for the treatment of thyroid nodules Thyroid RFA radiofrequency ablation technology is thermal ablation treatment between the internal tissues of the nodules, from the lesion directly ablate nodules, the efficacy and surgical excision equivalent. In addition, the ablation technique will enhance the activity of macrophages/immune cells in the body and activate antibodies at the same time, resulting in an ultra-minimally invasive procedure. The ultra-minimally invasive procedure is painless, with an incision of about 1 mm, leaving no scars and no aesthetic impact.
