Prognostic value of subthreshold biphasic electromyographic (EMG) waveforms in Type I loss of signal during thyroid intraoperative neuromonitoring

Key Points

• Postoperative vocal fold recovery is strongly associated with subthreshold biphasic electromyographic waveforms, highlighting their prognostic value.
• The presence of these waveforms indicates residual neural conduction, potentially aiding clinicians during thyroid surgery.
• Assessment of intraoperative neuromonitoring demonstrated improved sensitivity with optimized threshold settings.
• This study underscores the importance of effective intraoperative monitoring techniques for enhancing surgical outcomes.
