Özet:

 Objectives: This study aims to identify clinical parameters beyond recurrent laryngeal nerve RLN anatomy contributing to loss of signal LOS during thyroid surgery. Materials and Methods: We retrospectively analyzed the records of 171 initial thyroid surgery patients under intraoperative nerve monitoring IONM by a single surgeon. Patient characteristics, surgical details, and LOS data were recorded. All surgical procedures were performed using intermittent IONM in accordance with international guideline statements. Patients were categorized according to the presence of LOS LOS and LOS-, and logistic regression analysis was used to identify LOS-related factors. Results: Among 171 patients, 8 4.7 experienced LOS. LOS cases showed significantly lower tumornodule size and thyroid volume. No significant differences were observed in other variables between the LOS and LOS- groups. Logistic regression analysis identified tumornodule size 10 mm p0.006 and thyroid volume 12 mL p0.013 as significant factors. In 8 LOS patients, traction injuries were prevalent 87.5, mainly at the level of Berrys ligament, left-sided, and single-branch nerve anatomy in 87.5. Complete recovery of LOS occurred in 37.5 of LOS cases after the termination of traction. Conclusion: Small thyroid volume increases the risk of the development of LOS, due to excessive RLN stretching during surgery. Our findings highlight the importance of minimizing traction and using continuous IONM to prevent LOS and subsequent vocal cord paralysis. Key Words: Thyroidectomy, Electromyography, Vocal Cord Paralysis, Loss of Signal, Intraoperative Neuromonitoring.
