Producing a human voice requires precise airflow regulation from the lungs to the oropharynx in tandem with the glottic posture. To display their dynamic vibratory properties, the vocal folds must be correctly compliant. Dysphonia can be caused by factors that affect the glottis’s vibratory nature (such as a laryngeal cyst) or its aerodynamic structure (such as vocal fold paralysis). However, a functional voice problem should be considered when vocal quality declines without corresponding changes in anatomy or the nervous system. Many people believe that phono-trauma causes vocal fold nodules (VFNs), which are benign growths on the medial surface of the true vocal folds (TVFs) and are frequently referred to as singer’s nodules or nodes (as shown in the video below). The nodules are found on both sides of the vocal fold, with a typical site where the anterior and middle thirds of the fold meet (i.e., the midpoint of the membranous vocal fold). Women in their 20s and 30s are the most prevalent age group to have nodules, although children, especially boys, who are more likely to scream or shout than females, can also develop them.
