1. The muscles attached to the arytenoid cartilages control the degree of opening. 2. The epiglottis and arytenoids are cherry-red and swollen. 3. This lack of nerve supply renders the arytenoid cartilage immobile. 4. Arytenoid adduction is a surgical procedure used to treat vocal cord paralysis.5. Arytenoid adduction is often performed in conjunction with medialization thyroplasty.6. This rotates the arytenoid cartilage and adducts the vocal cord. 7. Arytenoid adduction is often performed at the same time as a medialization thyroplasty.8. Arytenoid adduction is more effective than medialization thyroplasty for closing a posterior gap.9. Thus arytenoid adduction can correct the vertical position of an elevated vocal cord. 10. Arytenoid adduction produces improvements in all of these parameters.
