Vocal cord paresis, also known as recurrent laryngeal nerve paralysis or vocal fold paralysis, is an injury to one or both recurrent laryngeal nerves (RLNs), which control all intrinsic muscles of the larynx except for the cricothyroid muscle. The RLN is important for speaking, breathing and swallowing.
Trauma is often due to excessive use of the vocal folds such as by yelling, screaming, or singing. Though this often results in damage to the outer layers of the vocal folds, the subsequent healing process may lead to changes in the physiology of the folds. [1] Another potential cause of inflammation may be overuse of the vocal cords.
By lowering vocal pitch, the larynx compresses the vocal folds which regulate air flow and production of the sounds used in speech which can cause damage to these muscles over time. Vocal fold lesions or nodules can cause changes in the vocal fold mucosa which leads to increased tension in the larynx, ultimately causing dysphonia.
Vocal cord dysfunction (VCD) is a condition affecting the vocal cords. [1] It is characterized by abnormal closure of the vocal folds, which can result in significant difficulties and distress during breathing, particularly during inhalation. [1] Due to the similarity in symptoms, VCD attacks are often mistaken for asthma attacks or laryngospasms.
