To observe the therapeutic effect of modified Miccoli and transareolar endoscopic thyroidectomy in the treatment of papillary thyroid microcarcinoma (PTMC).

From January 2016 to June 2018, 105 patients with PTMC received surgical treatment were enrolled into present study. who were randomly divided into observation group (53 cases) and control group (52 cases). Patients in observation group received modified Miccoli routine operation, while patients in control group received totally laparoscopic thyroid surgery. Statistical analysis were performed by using SPSS 21.0 software. Measurement data, such as intraoperative all indexes, PTH before and after surgery, postoperative blood calcium levels, and each score (VAS score, RSI grade, VHI) were expressed as(±s), and were examined by using independent t test. Count data such as incidence of postoperative complication rate were examined by chi square test. A P value <0.05 was considered as statistically significant difference.

The incision length, operation time, intraoperative blood loss, postoperative drainage volumn, neck recovery time, average extubation time and hospital stay in the observation group were significantly better than those in control group respectively (P<0.05). 3 days after operation, the serum calcium level of PTH in the observation group was higher than that in the control group, with significant difference (P<0.05). The VAS score in the observation group was lower than that in control group at 12 h and 24 h postoperatively (P<0.05). The VHI score and the beauty satisfaction score in the observation group were better than those in the control group respectively (P<0.05). There was no significant difference between the two groups in terms of incidence of postoperative complications

The modified Miccoli is effective in the treatment of PTMC with shorter operation time, less intraoperative bleeding, less postoperative complications and better cosmetic effect. It is worth popularizing.
