Vocal Fold Paresis

Abstract

This article discusses vocal fold paresis as a separate and distinct condition from vocal fold paralysis. The signs and symptoms of paresis may be different and less obvious than those for paralysis, so this condition is often misdiagnosed or underdiagnosed. Elements necessary to heighten clinical suspicion are included to assist in educating practitioners on these subtle findings. Once paresis is suspected, associated respiratory or sensory abnormalities also should be sought, because these may change the treatment plan when recognized. Utility of laryngeal electromyography is discussed along with potential treatment options for both the motor and often-present sensory symptoms.
