Abstract
Isshiki Thyroplasty Type I, a surgical procedure to medialize a paralyzed vocal cord through a window made in the thyroid lamina, has been widely performed to improve hoarseness and misdeglutition in cases of unilateral recurrent nerve paralysis. The medialization of the vocal cord is usually obtained by the insertion of a silicone shim through the window, but the trimming of the silicone is troublesome, and the operation cannot be done without silicone. Thus, we recently devised a new method using a fragment of cartilage instead of silicone. In this method, a vertical portion of the rectangular cartilage removed from the window in the thyroid lamina was inserted between the thyroid cartilage and the endochondrium at the level of the window and was fixed with fibrin glue. This procedure is easy to perform and does not necessitate silicone. Two cases with good results using this method were reported.
