Vocal Cord Nodules (also called Singer's Nodes, Screamer's Nodes)
Vocal cord nodules are also known as “calluses of the vocal fold.” They appear on both sides of the vocal cords, typically at the midpoint, and directly face each other. Like other calluses, these lesions often diminish or disappear when overuse of the area is stopped.
Vocal Cord Polyp
A vocal cord polyp typically occurs only on one side of the vocal cord and can occur in a variety of shapes and sizes. Depending upon the nature of the polyp, it can cause a wide range of voice disturbances.
Vocal Cord Cyst
A vocal cord cyst is a firm mass of tissue contained within a membrane (sac). The cyst can be located near the surface of the vocal cord or deeper, near the ligament of the vocal cord. As with vocal cord polyps and nodules, the size and location of vocal cord cysts affect the degree of disruption of vocal cord vibration and subsequently the severity of hoarseness or other voice problem.
Reactive Vocal Cord Lesion
A reactive vocal cord lesion is a mass located opposite an existing vocal cord lesion, such as a vocal cord cyst or polyp. This type of lesion is thought to develop from trauma or repeated injury caused by the lesion on the opposite vocal cord. A reactive vocal cord lesion will usually decrease or disappear with voice rest and therapy.
Our approach to dealing with nodes, nodules,
cysts, legions and polyps is revolutionary and non-surgical.
