Like fingerprints, each person’s voice is unique. When air from our lungs passes through the larynx, or voice box, it causes the vocal cords in the larynx to vibrate, thus producing sound.
Voice disorders occur when the vocal cords are injured. Common causes include vocal strain (talking too much, yelling), viral infections or smoking. These can also lead to problems such as nodules, polyps and sores on the vocal cords.
Treatment for voice disorders varies depending on the cause. Most voice problems can be successfully treated when diagnosed early.
