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.
This research project conducts a detailed exploration into the fluctuations of intraoperative recurrent laryngeal nerve monitoring signals during thyroid surgery and their subsequent effects on the voice quality of patients after surgery. The study meticulously analyzes a comprehensive dataset comprised of surgical records and voice analyses conducted before and after the procedure. The primary objective is to pinpoint specific trends and changes in the nerve monitoring signals and to determine how these alterations correlate with the postoperative acoustic characteristics of patients' voices. By establishing a clear link between intraoperative signal dynamics and postoperative voice outcomes, the investigation aims to advance the field of thyroid surgery. This includes providing surgeons with critical insights for the precise evaluation of recurrent laryngeal nerve functionality, enabling targeted interventions during operations, and ultimately contributing to the enhancement of patients' quality of life following surgery. Through this rigorous analysis, the study seeks to contribute valuable knowledge to the surgical community, facilitating improved patient care and outcomes in thyroid surgery.

Voice Handicap Index, including a scale with 30 items.The full, non-abbreviated title of the VHI-30 scale is the "Voice Handicap Index-30," and it is translated as the "Voice Disorder Severity Index." The scale ranges from a minimum score of 0 to a maximum of 120, with higher scores indicating poorer outcomes. |
