Vocal Cord Polyps and Nodules
Phonotrauma (overuse of the vocal cords) leads to mechanical stress and occasionally results in callouses (nodules) or larger growths (polyps). The difference between a polyp and nodule is sometimes arbitrary. A large nodule is a small polyp, and vice versa. In this photo, some might characterize the left vocal fold lesion (left side of the photo) as a large nodule, while the right sided vocal fold lesion might be considered a small polyp.
Both types of growth result from vocal overuse. In general, nodules have a change of decreasing in size and even disappearing if the phonotraumatic behavior is eliminated. Whereas polyps rarely disappear without surgery. In this case, I doubt either of these vocal fold lesions would regress with voice rest or voice therapy. Hence surgery was recommended.
