Abstract
Typically, surgical intervention is required to remedy abnormalities of the vocal cords. However, surgical intervention often causes a laryngeal web, or glottic web, to form which impairs the sound quality of the vocal cords. The prosthesis and methods of the invention effectively eliminate regrowth of a laryngeal web after surgery over all other prior art devices and methodologies. During the operative procedure, the prosthesis may be inserted through a surgically created hole in a laryngeal web allowing a laryngeal bridge to assist in holding the prosthesis in position. Following surgery, after the vocal cords heal, the prosthesis may then be removed, and the laryngeal bridge also removed. In the case of an anterior procedure, the prosthesis produces a sharp anterior commissure without any glottic web. The prosthesis and method greatly reduce the recurrence of a laryngeal web.
