What is a nodule? Is it the same thing as a polyp?
A nodule is a benign growth on the vocal fold that usually occurs on both vocal folds and is caused from chronic vocal abuse (kind of like a callus). A polyp is also typically a benign vocal fold growth, although polyps generally occur only on one side and often arise from a traumatic incident to the vocal folds, e.g., after a vocal fold hemorrhage or mucosal tear.
