For restoring unilaterally bowed vocal fold, to appropriate height arytenoid adduction / rotation can be used, when there is complete vocal fold paralysis.
32.
When tumor formation is suspected, parts of the hypopharynx and the upper esophagus and passive mobility of the arytenoid cartilage are endoscopically examined under anesthesia.
33.
These muscles act on the arytenoid cartilages at the posterior ends of the vocal cords and are innervated by the left and right recurrent laryngeal nerves.
34.
It has been suggested that this is because arytenoid adduction directly rotates the arytenoid cartilage and thus more actively medializes the posterior aspect of the vocal cord.

36.
It is opened if the back part of the Arytenoid catilage is pulled apart while the front part is close together in order to facilitate closed vocal folds.
37.
When twanging, the opening of the epiglottic funnel is made smaller by bringing the arytenoid cartilages closer to the lower part of epiglottis ( the petiole ).
38.
The suture placed in the arytenoid adduction procedure mimics the action of the lateral cricoarytenoid muscle and pulls the vocal process of the arytenoid cartilage medially and inferiorly.

The suture placed in the arytenoid adduction procedure mimics the action of the lateral cricoarytenoid muscle and pulls the vocal process of the arytenoid cartilage medially and inferiorly.
40.
A sub-group of children may have occult laryngomalacia, where the tissue directly above the vocal cords ( epiglottis, arytenoids ) collapses into the airway during sleep.
