1. Do all thyroid adenomas detected need to be treated? What are the treatment methods? Thyroid adenoma (non-nodular goiter) is a true benign tumor of the thyroid gland and needs to be treated, mainly by surgery, iodine 131 and medication. 2. Can medication alone stop the growth of adenoma and avoid surgery? Can it be cured? TSH suppression therapy is usually used to suppress the serum TSH level to the low limit of normal or even below the low limit by using thyroxine preparations in order to suppress the pro-growth effect of TSH on thyroid cells and achieve the goal of shrinking thyroid nodules. Strictly speaking, surgery is the preferred treatment for thyroid adenoma, and drug therapy is not suitable for this patient. 3.What kind of thyroid adenoma needs surgery? Surgery is the first choice for clearly diagnosed thyroid adenomas (not nodular goiter), except for high-functioning adenomas with autonomic uptake. 4. Can removal of adenoma be cured? Surgery is curable. 5.What is minimally invasive thyroid surgery? What is the treatment effect? There is still a controversy about whether lumpectomy is minimally invasive, but the biggest advantage of lumpectomy is the cosmetic effect and no scar on the neck after surgery. 6.What are the advantages and disadvantages of minimally invasive surgery compared to traditional surgery? What kind of patients are they suitable for? Which patients are not suitable? Laparoscopic thyroid surgery is suitable for a special group of patients who have high demands on the appearance of the neck. At present, lumpectomy is mainly used for benign thyroid lesions less than 100px and early stage thyroid cancer patients, while lumpectomy for thyroid cancer is still controversial. 7.Is iodine 131 treatment for thyroid adenoma feasible? What kind of patients are suitable for iodine 131 treatment? What is the efficacy? What are the contraindications? Iodine 131 is mainly used to treat benign thyroid nodules with autonomic uptake and hyperthyroidism. For nodules with autonomic uptake but without hyperthyroidism, Iodine 131 may be an option. Iodine 131 therapy is not recommended for thyroid nodules with symptoms of pressure or located behind the sternum. Being pregnant or breastfeeding is an absolute contraindication to iodine 131 treatment. After 2 to 3 months of iodine 131 treatment, nodules with autonomic function may gradually shrink and thyroid volume may be reduced by an average of 40%; in cases with hyperthyroidism, symptoms, signs and related complications of hyperthyroidism may gradually improve while nodules shrink, and thyroid function indicators may gradually return to normal. (From domestic 2012 guidelines) 8. How should scar patients choose their treatment? The essential surgical approach for scar patients is no different from that for non-scar patients. The scope of flap dissection and unnecessary dissection should be minimized intraoperatively. The surgical approach should be as concealed as possible, such as the lumpectomy route. Early postoperative treatment can be combined with other treatments related to scar formation prevention.
