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.

摘要： 【摘要】目的探讨对甲状腺乳头状微小癌（PTMC）患者行中央区淋巴结清扫的效果。方法选择2008年4月~2011年5月在本院接受手术治疗的58例PTMC作为研究对象，将行中央区淋巴结清扫的30例患者作为观察组，将未行中央区淋巴结清扫的28例患者作为对照组，回顾性分析2组患者治疗效果。结果观察组、对照组同一侧颈部淋巴结的转移率分别为3.33%、 17.86%，观察组明显低于对照组，组间差异比较有显著性（P<0.05）；2组并发症发生率分别为23.33%、21.43%，组间比较无显著性差异（P>0.05）。结论甲状腺乳头状微小癌需要进行中央区淋巴结清扫来降低转移。
