Methods: Five thyroid-related cell lines-normal thyrocytes (Nthy-ori 3-1), papillary thyroid cancer (PTC) cells (SNU-790, TPC-1), poorly differentiated thyroid cancer cell (BCPAP), and anaplastic thyroid cancer cell (SNU-80)-were cultured under simulated microgravity (10 g) using a clinostat.

First Experience of Single Port Robotic Areolar (SPRA) Thyroidectomy and Modified Radical Neck Dissection (MRND).

: After introducing the single-port robotic surgical system (da-Vinci SP), thyroid surgeries using da-Vinci SP are becoming more popular. Although many methods have been designed for thyroidectomy using the da-Vinci SP, there are very few reports on methods that can perform not only thyroidectomy but also lateral cervical lymph node dissection. In this study, we want to report the first clinical experience with SPRA-MRND (Single Port Robotic Areolar-Modified Radical Neck dissection), using right breast access.

Intraoperative pathologic evaluation (IOPE) can provide evidence regarding CLNM and help surgeons determine the appropriate surgical approach. The aim of this study was to evaluate the efficacy of IOPE and to determine risk factors associated with CLNM in unilateral PTC without preoperative clinical evidence of CLNM.
