To investigate the clinical value of totally endoscopic thyroidectomy in treating papillary thyroid microcarcinoma(PTMC).

The clinical data and follow-up data of 40 patients with PTMC were retrospectively analyzed from October 2015 to June 2018. They were divided into two groups, 20 patients with totally endoscopic thyroidectomy(group A), 20 patients with conventional open thyroidectomy(group B). SPSS 17.0 was used to process data. The quantitative data were expressed in (±s), compared with t test. χ² test and Fisher exact test were used to compare postoperative complications、neck comfort、recurrence and metastasis and so on between two groups, the difference was statistically significant if P<0.05.

The operative time and average hospital stay in group A were significantly longer than group B (P<0.05); There were no significant difference in postoperative complications、number of the lymph node dissection between the two groups. Neck comfort in group A was significantly better than group B; During the follow-up, there were no tumor recurrence or metastasis in all patients.

The totally endoscopic thyroidectomy in treating early-stage differentiated thyroid carcinoma (DTC) especially in PTMC may achieve a similar curative effect compare with open group. It does not affect the prognosis of patients, and could meet the cosmetology of patients especially for women. It is worth for clinical development.
