Positive Predictive Value of Endoscopic Findings to Diagnose Vocal Fold Paresis

Laryngoscopy corresponding with laryngeal electromyography (LEMG) is essential in diagnosing vocal fold paresis. However, baseline asymmetry or other diseases oftentimes confound the exam, making diagnosis difficult. There is currently no agreed upon endoscopic criteria proven to reliably correlate with LEMG findings. We define a set of endoscopic findings termed “paresis triad” that, when present together, reliably correlate with LEMG. The paresis triad consists of (1) hypocontraction of the weak side of the larynx with increased ventricular show, (2) hypercontraction of the intact side with bulging of the false fold covering the ventricle, and (3) tilting of the interarytenoid cleft to the weak side.
