About

Intraoperative nerve monitoring is often used in many centers during thyroidectomy. According to the investigators' knowledge, there's no study showing superiority between bipolar and monopolar stimulation probes used for nerve monitoring during thyroid surgery. In this study, the investigators aimed to compare two different types of probes and find out superiorities.Twenty-one patients who underwent primary total thyroidectomy or hemithyroidectomy were included in the study. During surgery, amplitude and latency values obtained in the same patient with both bipolar and monopolar stimulation probes from 10 different anatomical spots [vagal nerve, recurrent laryngeal nerve inferior portion, recurrent laryngeal nerve superior portion, external branch of superior laryngeal nerve (EBSLN)] were recorded prospectively, both when sheath was intact and after being dissected.
