Abstract
We described the method for combination of two operations, the lateral cricoarytenoid muscle (LCA) pull-surgery and Isshiki's thyroplasty of type I.The indication of this procedure is when there is a noticeable displacement of the arytenoid cartilage. This displacement is judged by the level difference or large inter-arytenoid distance. The LCA pull-surgery is one of the arytenoid adduction methods that the nylon-threads sutured to the lateral cricoarytenoid muscle are pulled antero-caudally without exposing the muscular process through the window in the thyroid ala. Since the operating field is similar to that of type I thyroplasty, this method reduces the damage to the surrounding tissues, compared with the method through posterior edge of the thyroid ala. The combination of thyroplasty of type I is performed in the same operating field by a slight enlargement of the window in the thyroid ala. Since the procedure do not need to rotate the thyroid cartilage, we can reduce the discomfort of the patients under topical anesthetic conditions.
