Changes in electromyographic amplitudes but not latencies occur with endotracheal tube malpositioning during intraoperative monitoring for thyroid surgery: Implications for guidelines
Objectives/Hypothesis: During intraoperative neural monitoring (IONM) in thyroid and parathyroid surgery, endotracheal
(ET) tube migration can result in a decrease in vocalis electromyographic (EMG) amplitude without a concordant latency
elevation during stimulation of the recurrent laryngeal nerve (RLN).
Study Design: Retrospective review.
Methods: Data were reviewed retrospectively for thyroid and parathyroid surgery patients with IONM of the laryngeal
