| 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.
