Surgical correction of the convex vocal cord after Teflon injection.

Teflon injection of paralyzed and bowed vocal cords has been performed since 1962. It has been generally accepted that nothing could be done if an excess is injected or a granuloma reaction within the cord occurs causing an early or late convex cord which projects across the midline. A technique is described to correct such convex cord problems and the results are given for 12 patients for whom corrective surgery was done.
