Using Neuromonitoring to find EBSLN: intraoperative neuromonitoring to preserving external branch of superior laryngeal nerve during thyroid surgery

Study summary

The frequent occurrence of impaired function in the external branch of the superior laryngeal nerves following thyroid surgery is recognized as a prevalent complication leading to a diminished quality of life. The objective of this randomized controlled trial (RCT) is to assess the efficacy of neuromonitoring during thyroid surgery in order to safeguard the integrity of these nerves.
