Paradoxical Vocal Fold Movement
What Is Paradoxical Vocal Fold Movement?
Paradoxical vocal fold movement is a lesser form of spasm where the vocal folds narrow but do not close completely. It may be mistaken for asthma and may cause noisy or restricted breathing. Treating effectively usually involves treating any infection, control of inflammation, treatment of allergies, appropriate hydration and humidification, and occasionally medications to reduce nerve irritability. If the underlying inflammation is treated, this condition is usually temporary. Reflux can cause spasm as well, often in the middle of the night, so if reflux is present it is important to treat it appropriately.
Occasionally speech therapy may be helpful to teach the patient relaxation breathing techniques.
