Abstract: 【Abstract】 Objective To summarize the clinical effect of central neck lymph node dissection in patients with papillary thyroid microcarcinoma（PTMC）. Methods Fifth-eighty patients with PTMC from April 2008 to May 2011 were included in the study, in which 30 cases were subjected to central neck dissection（observation group）and 28 cases underwent thyroidectomy alone. The lymph node metastasis was analyzed. Results Observation group and control group with ipsilateral neck lymph node metastasis were 3.33%, 17.86%, respectively（P<0.05）, and the complications in observation and control groups were 23.33%, 21.43%, and there was no significant difference between groups. Conclusion Central neck dissection for PTMC surgery effectively reduces the lymph node metastasis and does not increase com-plications.
