8) It is interesting to note that in 2 of these patients, botulinum toxin was injected into the thyroarytenoid muscle to "diminish forces pulling the vocal process away from the body of the arytenoid cartilage.
The arytenoid cartilage serves as the primary fulcrum in vocal fold movement, and it articulates with the cricoid ring via the synovial cricoarytenoid joints.
In addition to pulling the bodies of the arytenoid cartilages together, the IA seems to act as an accessory abductor, effecting a backward (and medial) sliding motion of the arytenoid.
If doubt persists as to a mechanical laryngeal immobility, direct laryngoscopy under general anesthesia with palpation of the arytenoid cartilage and evaluation of the posterior glottis is indicated.
The larynx is by no means responsible for song in birds, as the arytenoid cartilages are immobile and there are no vocal folds.
