For thyroid microcarcinoma(TMC),the incidence is not obvious,the lesion is small,the symptoms are not distinctive and the progression is slow. Studies suggest that patients with the age over 45 years or below 15 years old,male,lesion over 5 mm and lymph node metastasis have poor prognosis and active opera-tion treatment is needed. When in operation,the excision extension should take clinical data into consideration, and complete resection of the lesions and preservation of the normal tissue as much as possible should be done. For the patients with lymph node metastasis,lymph node dissection is feasible,and the central lymph node dis-section is applicable for the negative lymph nodes. Reduce the risk of recurrence and metastasis,increase the survival rate of patients with tumor and improve the quality of life,become the prime target of the follow up,in which the standardized treatment of TMC plays a vital role.
