Intraoperative Neuromuscular Monitoring and Its Impact on Pre- and Postoperative Acoustic Outcomes in Thyroid Surgery

Summary

This study examines the impact of intraoperative recurrent laryngeal nerve monitoring signal changes on the postoperative voice quality of thyroid surgery patients. By analyzing extensive surgical data and postoperative voice recordings, the investigation seeks to identify patterns in the variations of these signals and their correlation with voice quality outcomes. The goal is to enhance clinical understanding and surgical practices, allowing for more precise assessments of nerve function, informed surgical interventions, and improved postoperative patient well-being.
