OBJECTIVES/HYPOTHESIS: To confirm the value of using laryngeal electromyography (LEMG) to predict the long-term prognosis of unilateral vocal fold paralysis (UVFP), and elucidate the adequate timing of LEMG. STUDY DESIGN: Prospective cohort prognosis study. METHODS: The LEMG data of 84 patients with UVFP were prospectively collected, and 81 patients received follow-up at least 6 months after symptom onset. If the paralyzed vocal fold had <20% recruitment reduction during phonation compared to the normal vocal fold signals, and absence of fibrillation when the patient was silent, the prognosis was considered to be good (negative finding). Otherwise, the prognosis was considered to be poor (positive finding). The association between UVFP...
