One of the major perceptual signs of vocal fold nodules is a change in the quality of the voice. [1] The voice may be perceived as hoarse, [4] [5] due to aperiodic vibrations of the vocal folds, [5] and may also be perceived as breathy, [4] [5] due to an incomplete closure of the vocal folds upon phonation.
Vocal nodules are caused over time by repeated abuse of the vocal cords which results in soft, swollen spots on each vocal cord. [24] These spots develop into harder, callous-like growths called nodules. The longer the abuse occurs the larger and stiffer the nodules will become.

The human vocal cords are roughly 12 – 24 mm in length, and 3–5 mm thick. [9] Histologically, the human vocal cords are a laminated structure composed of five different layers. The vocalis muscle, main body of the vocal cords, is covered by the mucosa, which consists of the epithelium and the lamina propria. [10]
The vocal folds consist of 3 primary layers; the Epithelium, the Lamina Propria (containing superficial, intermediate and deep layers) and the Thyroarytenoid Muscle. Vocal fold cysts commonly appear in the Superficial portion of the Lamina Propria, the cyst size impacts the nature of this layer making it more rigid.
Laryngologists treat disorders of the larynx, including diseases that affects the voice, swallowing, or upper airway. Common conditions addressed by laryngologists include vocal fold nodules and cysts, laryngeal cancer, spasmodic dysphonia, laryngopharyngeal reflux, papillomas, and voice misuse/abuse/overuse syndromes.
Vocal cord nodules and polyps are different phenomena, but both may be caused by vocal abuse, and both may take the form of growths, bumps, or swelling on the vocal cords. Vocal fold paralysis is the inability to move one or both of the vocal cords, which results in difficulties with voice and perhaps swallowing. Paradoxical vocal fold movement ...
Reinke's edema is the swelling of the vocal cords due to fluid collected within the Reinke's space. [2] First identified by the German anatomist Friedrich B. Reinke in 1895, the Reinke's space is a gelatinous layer of the vocal cord located underneath the outer cells of the vocal cord.
