RESUMO
Objective To analyze the clinical characteristics,diagnosis and treatment of thyroid micro-carcinoma.Methods The clinical data of 52 cases of thyroid micro-carcinoma operated from 2003 to 2008 were analyzed retrospectively.Results All of the 52 cases were confirmed as thyroid micro-carcinoma by postoperative pathologic exam;30 cases(57.7%) were discovered by intraoperative frozen section and 22 cases were not.Micro-calcification ratio on ultrasound was 35.19%.11 cases were diagnosed as malignant tumor on ultrasound scan preoperatively.Lobectomy of involved lobe with subtotal thyroidectomy of contra-lateral lobe was performed in 38 cases,3 cases of bilateral total thyroidectomy,3 cases of unilateral lobectomy and isthmectomy,5 cases of ipsilateral subtotal lobectomy and 3 cases of ipsilateral lobectomy with isthmectomy were performed.Combined central region lymph nodes dissection was adopted in 27 cases(positive 11/27,40.74%).Follow-up rate was 96.2%,with time ranging from 3 months to 5 years.No recurrence or mortality was discovered.Conclusions(1)B type ultrasound is the first choice for preoperative screening.(2) lpsilateral thyroid lobectomy with contralateral subtotal thyroidectomy combined with central region lymph node dissection is advocated.
