Vocal Fold Polyps

A vocal fold polyp typically occurs only on one side of the vocal fold. Although there may be some similarities, polyps do not look like nodules when examined under the microscope. They are typically more reddish, due to increased blood vessel supply (vasculature). A vocal fold polyp can occur in a variety of shapes and sizes. Depending upon the nature of the polyp, it can cause a wide range of voice disturbances.
