Abstract

Abstract: Objective To explore the clinical significance of metastasis to recurrent laryngeal nerve lymph nodes at entrance point (RLNLN-ep) in the patients with papillary thyroid carcinoma (PTC). Methods An analysis was done inclu-ding 598 consecutive patients with PTC who underwent thyroid surgery from April 2016 to November 2016. We explored RLNLN-ep in central compartment lymph node dissection. Carbon nanoparticles were injected into the lobes to help identify lymph nodes. RLNLN-ep and the other central compartment lymph nodes were sent for pathological examination. The complications were recorded. Results RLNLN-ep was found in 35 of 598 (5.85%) cases. There were 15 (2.51%) cases with metastasis of PTC and 20 cases without the metastasis. The metastasis rate of RLNLN-ep was related to tumor diameter, tumor location and the amount of tumor. The amount of tumor was an independent factor of metastasis of RLNLN-ep. There were 14 (93.3%) cases with metastasis of RLNLN-ep who were found the other central compartment lymph node metastasis simultaneously. Seven (1.2%) cases had morbidity postoperatively. Conclusions RLNLN-ep could be the site of metastasis of PTC. Central compartment lymph node dissection should include RLNLN-ep and the surrounding tissue.
