A vocal cord nodule is a mass of tissue that grows on the vocal folds (vocal cords). Typically, this mass will appear on the junction of the anterior and middle two-thirds of the vocal fold, where contact is most forceful.

A vocal cord nodule reduces or obstructs the ability of the vocal folds to create the rapid changes in air pressure which generate human speech. Symptoms include hoarseness of speech, painful speech production, frequent vocal breaks, and reduced vocal range. Vocal fold nodules develop mostly in adult females, and children of both sexes.[1]

The nodules appear as symmetrical swellings on both sides of the vocal cords. The cause of these formations are usually strenuous or abusive voice practices such as yelling and coughing. Those who use their voice constantly in a loud environment are susceptible.

Prognosis [link]

Vocal cord nodules can certainly impair one's speaking and singing ability. They rarely harm one's general health. Indeed, the psychological trauma of being diagnosed with nodules—a trauma affecting those especially whose professional success depends on consistently producing a rich and powerful vocal tone (e.g. singers, actors, litigation lawyers, broadcasters)—typically dwarfs the limited systemic and even otolaryngological effects.

Treatment [link]

Treatment, or voice rehabilitation, usually involves vocal training, speech therapy, and, occasionally, vocal rest. In rare cases, surgery may be required. Removal of vocal cord nodules is a relatively safe and minor surgery. However, those who sing professionally or otherwise should take serious consideration before having surgery as it can affect the ability to sustain notes, as well as alter the vocal range. Examples of this are José José and Julie Andrews, who lost much of their singing ability after undergoing vocal nodule surgery. While the patient is subdued under general anesthesia, long thin scissors and scalpels are used to remove the nodules, or CO2 surgical lasers might be used which are very effective in such cases. The best preventive steps seem to be wrapped up in the study of vocology, the science and practice of voice habilitation.

Symptoms of vocal nodules include vocal fatigue and hoarseness or breathiness. Hoarseness or breathiness that lasts for more than two weeks may signal a voice disorder and should be followed up with an appointment with an otolaryngologist.

Vocal folds

The vocal folds, also known commonly as vocal cords or voice reeds, are composed of twin infoldings of mucous membrane stretched horizontally, from back to front, across the larynx. They vibrate, modulating the flow of air being expelled from the lungs during phonation.

Open when breathing and vibrating for speech or singing, the folds are controlled via the vagus nerve.

Structure

The vocal folds are located within the larynx at the top of the trachea. They are attached posteriorly to the arytenoid cartilages, and anteriorly to the thyroid cartilage. They are part of the glottis which includes the rima glottidis. Their outer edges are attached to muscle in the larynx while their inner edges, or margins are free, forming the opening called the rima glottidis. They are constructed from epithelium, but they have a few muscle fibres in them, namely the vocalis muscle which tightens the front part of the ligament near to the thyroid cartilage. They are flat triangular bands and are pearly white in color. Above both sides of the glottis are the two vestibular folds or false vocal folds which have a small sac between them.
