ABSTRACT
BACKGROUND AND OBJECTIVES: Functional diseases of vocal folds have shown various movements of the arytenoid cartilage, however, they have not been documented yet. We studied to find out the relationships between functional diseases of vocal folds and arytenoid movements. MATERIALS AND METHOD: 224 subjects were evaluated by using videostroboscopic examinations. The subjects were classified into three types; notch, ball, and flat types according to the patterns of arytenoid movement during phonation. Vocal fold lesions were investigated and arytenoid movements were compared between normal and disease groups. RESULTS: The arytenoid movements of notch type were more than ball type or flat type in both normal and disease groups. The disease group showed many asymmetric movements of arytenoid cartilage when compared with the normal group. Vocal nodule and vocal polyp showed asymmetric movements of arytenoid cartilage. Conclusions: We found that the functional diseases of vocal folds were related to the asymmetric movements of arytenoid cartilage. We suggest that the various movements of arytenoid cartilage should be considered when functional diseases of vocal folds are examined.
