New Resources

Updated fact sheets about hoarseness, vocal fold paralysis, and assistive devices are now available in print and online on the NIDCD website.


Using your voice too much or too loudly can cause hoarseness, but sometimes hoarseness is also an indicator that something more serious is happening with the tissues and structures that make up the larynx or the muscles that control them. In this fact sheet, you’ll learn about how your voice works, when to see your doctor if you’re hoarse, how your doctor will make a diagnosis, disorders that can cause hoarseness, and research currently being done to better understand hoarseness.
