In recent years, the incidence of thyroid cancer has rapidly increased worldwide [1]. In some countries, the growth rate of thyroid cancer ranks the first among solid tumors in the whole body [2]. The increase of thyroid cancer is mainly attributed to the growth of papillary thyroid microcarcinoma (PTMC, diameter ≤10 mm) [2]. With the explosive growth of PTMC, the controversy over its diagnosis and treatment is also exacerbated [3-4]. However, whether PTMC performs central lymph node dissection and clearance
