[Effects and use of the suture direction mimicking only the force action of the lateral cricoarytenoid muscle in arytenoid adduction combined with thyroplasty type I].

Abstract

Isshiki's arytenoid adduction combined with thyroplasty type I is a useful procedure for correcting the membranous vocal fold atrophy and the height difference between the two vocal folds, particularly in patients with a large posterior glottal chink and atrophy. Conventional arytenoid adduction (Isshiki's arytenoid adduction) is designed to place a suture through the muscular process of the arytenoid attached anteriorly to the thyroid ala, stimulating the function of the thyroarytenoid muscle and lateral cricoarytenoid muscle. Combining with thyroplasty type I, the suture direction of conventional arytenoid adduction prevented inserting implant material into the pocket of the thyroid cartilage window. In contrast to conventional arytenoid adduction, the suture direction in our approach is anchored anteroinferiorly, mimicking only the action of the lateral cricoarytenoid muscle (the major adductor of the larynx). It is used the thyroid cartilage window in thyroplasty type I to determine the direction of the lateral cricoarytenoid muscle. After approaching the muscular process based on Isshiki's arytenoid adduction, two nylon sutures are tied across the muscular process or the lateral cricoarytenoid muscle nearby the muscular process. The cricoarytenoid joint is not dislocated. One of the sutures was anchored to the inferior rear corner of the thyroid cartilage window to be used with thyroplasty type I and the other was anchored to the rear lower margin of the thyroid lamina. Gore-tex medialization thyroplasty is done after tying the sutures on the thyroid ala. Subjects were 30 unilateral paralytic dysphonia. Maximum phonation of all patients improved significantly after surgery. The preoperative and postoperative mean maximum phonation times were 6.0 and 17.9 seconds. No major complications occurred in this study. Our approach effectively combined arytenoid adduction and thyroplasty type I for patients with severe insufficient glottic closure.
