Like vocal nodules, a vocal polyp is caused by voice abuse.
However, it may be caused by a temporary damage or
an upper respiratory infection.
Continuous hoarseness and fatigue of the voice are symptoms of vocal fold nodules.
Through a scientific view, a vocal fold nodule developed in the center of a vocal fold can be observed.
The nodules are usually formed on areas of the vocal folds that receive the most pressure when the folds come together and vibrate.
Vocal fold nodules do not grow over a certain size, and do not cause breathing difficulties.
Polyps require microlaryngeal surgery or PDL laser surgery to remove polyps. When they are
caused by the abuse of the larynx, voice therapy should be done together.
