What are "polyps" and "nodules"?

Jason Hamilton (Facial Plastic & Reconstructive Surgeon) gives expert video advice on: How do I know if I have a voice problem?; What is the treatment for vocal chord lesions? and more...

Vocal nodules are benign. They're small swellings on the vocal cords, and they're usually caused from overuse of the voice. The vocal cords work by vibration, and by straining the voice, the cords actually beat against one another vigorously and form almost callouses, like you'd form on your hands, on the vocal cords. Typically, with rest and voice training, these nodules can subside on their own. If they don't subside, they can be removed surgically. Polyps are very similar to nodules and are typically caused by either vocal abuse or from smoking, and they again can be removed surgically, or they can improve with voice rest and voice training as well.
