Paradoxical Vocal Fold Motion in ALS Patient: A Case Report

Abstract

Paradoxical vocal fold motion (PVFM) can occur at any stage of amyotrophic lateral sclerosis (ALS). PVFM results in glottic narrowing or complete blockage of airway in ALS patients, which eventually leads to respiratory insufficiency and sudden death. ALS typically presents initially with weakness of hands and bulbar musculature. Rarely, hoarseness is the initial symptom in ALS. This is a case report of how PVFM presents initially with hoarseness as a first symptom of ALS.
