Abstract:

Objective To summarize up the experience in applying methylene blue dye to locate sentinel lymph nodes of cN0 thyroid papillary carcinoma. Mehtods Fifty?one patients of thyroid papillary carcinoma were performed sentinel lymph node biopsy by using methylene blue dye positioning. After Functional neck dissection ，the number of sentinel lymph nodes and cervical lymph nodes were recorded and analyzed. Results Among the 51 patients，46 cases were found to have blue?stain sentinel lymph nodes with a detection rate of 90.2% ，positive rate of 45.7% ，negative rate of 50% and false negative rate of 4.3%. The sensitivity was 91.3% （21/23），and the accuracy was 95.7% （44/46）. Conclusion Methylene blue as a tracer localizing sentinel lymph nodes on cN0 thyroid papillary carci? noma，evaluating the cervical lymphatic metastasis state ，and selecting surgical procedure，has the guid? ing significance.
